If you've inherited an apartment building in Los Angeles, your three immediate priorities are: confirm whether the building is covered by the Los Angeles Rent Stabilization Ordinance, get a current valuation that accounts for Measure ULA's transfer tax impact on properties above $5M, and consult a CPA about the stepped-up cost basis you receive at the date of death. Most decisions about whether to sell, hold, or exchange can wait 60 to 90 days, but ownership obligations to tenants begin immediately.
Inheriting an apartment building is not like inheriting a bank account. You receive the asset, the tenants, the regulatory obligations, the deferred maintenance, and the legal exposure as a single package. Some heirs who have never been landlords are surprised to discover they are responsible for responding to habitability complaints within 24 hours, that they cannot raise rents beyond the RSO annual allowable increase, and that removing a tenant from an RSO-covered building requires one of the specific just-cause reasons enumerated in Los Angeles Municipal Code Chapter XV. None of this is unmanageable, but it requires immediate awareness. This guide walks you through what to do, in the correct order, from the first week through the decision on your long-term path.

The first month determines whether you take control of the asset or let the asset control you. Start with these five actions in roughly this sequence, though some can run in parallel depending on your circumstances.
First, determine the legal mechanism of transfer. Was the building held in a revocable living trust? If so, the successor trustee can act relatively quickly. Was it held in the decedent's name alone without a trust? If so, the estate will likely need to go through California probate court, which typically takes nine to eighteen months before you can sell or formally transfer title. This distinction is critical because it determines your timeline for every other decision. Second, secure the property. If you are not yet the legal owner but the building is vacant or partially vacant, coordinate with the estate's attorney to ensure you have authority to access the property and that utilities and insurance remain active. Third, make contact with existing tenants. You do not need to tell them anything about your plans, but they need to know who to contact for maintenance issues. Failing to establish this contact creates liability under LA habitability law from the moment you have constructive knowledge of the building's existence.
Fourth, do not change anything about the tenants' terms until you understand the RSO rules. Do not raise rents. Do not serve notices you are not legally certain are proper. Do not make promises to tenants about their future in the building. Fifth, engage your professional team: an estate attorney or successor trustee attorney if probate is involved, a CPA who understands IRC Section 1014 and California FTB rules for inherited property, and a multifamily broker who knows LA to give you an initial read on what the building is worth in the current market.
How Do You Confirm RSO Coverage on an Inherited Apartment Building?
Nearly every apartment building in the City of Los Angeles constructed before October 1, 1978 is covered by the Los Angeles Rent Stabilization Ordinance (LAMC Chapter XV). This is not a technicality. It is the single most important legal framework governing your inherited asset. Understanding it changes every financial projection, every sale strategy, and every holding decision you will make.
RSO coverage means the following are now your legal obligations as the new owner: annual rent increases are capped at the allowable percentage set by the City each year (4% for the 2025-2026 RSO period, compounded from the tenant's base rent date); tenants can only be removed for one of the enumerated just-cause reasons in LAMC Section 151.09; if you use a no-fault just-cause reason such as owner move-in or substantial rehabilitation, you owe the tenant relocation assistance per the LAHD schedule (currently ranging from $10,650 to $26,550 or more depending on income and duration of tenancy); and habitability standards are enforced by the Los Angeles Housing Department, which can conduct inspections and issue orders to repair. You inherit all of this from the prior owner. Tenants do not lose their RSO status because the building changed hands through an estate.
An important nuance for heirs: even if some tenants are paying below-market rents, those rents represent both a short-term constraint and a long-term asset. When a rent-stabilized tenant vacates voluntarily, the unit undergoes vacancy decontrol under California Civil Code Section 1954.52, and the new rent can be set at market rate. A building with deeply discounted rents relative to market is not underperforming as an investment asset; it is accumulating decontrol potential that sophisticated buyers will pay a premium to acquire. Understanding this is one of the most important reframes available to heirs who are looking at below-market rent rolls and assuming they have a problem.
The table below summarizes the key RSO obligations you assume as an heir on the day you take title.
| RSO Obligation | What It Means for Heirs | Consequence of Violation |
|---|---|---|
| Annual rent increase cap (4% for 2025-2026) | Cannot raise rent above the allowable percentage regardless of how long ago the last increase was given | LAHD can order rollback; tenant can sue for triple damages |
| Just-cause eviction requirement | Cannot evict a tenant without one of the enumerated LAMC 151.09 reasons; an ownership transfer is not just cause | Unlawful detainer dismissed; potential harassment claim under LAMC 151.10 |
| Relocation assistance for no-fault evictions | Owner move-in, substantial rehab, and demolition require payment of LAHD-schedule relocation amounts | Eviction invalid without payment; liability for tenant's costs if forced to vacate without assistance |
| Habitability and maintenance | Responsible for all habitability items including plumbing, heating, weatherproofing, and pest control from day one | LAHD Orders to Comply; rent reductions; potential rent escrow by tenants |
| Posting requirements | Must post the current RSO allowable increase notice and rent registration documents | Technical violations that can complicate a sale or permit application |
| Annual rent registration | Must register units annually with LAHD and pay per-unit registration fees | Cannot legally impose a rent increase while registration is lapsed |
How Does Stepped-Up Cost Basis Work for Heirs?
The stepped-up basis under Internal Revenue Code Section 1014 is the most powerful tax advantage available to you as an heir, and most heirs do not fully understand it until they are already planning a sale. Here is the core mechanism: when you inherit real property, your cost basis is reset to the fair market value of the property at the decedent's date of death, not what they paid for it decades ago. This means that all of the capital gains that accumulated during the prior owner's lifetime are permanently eliminated for federal tax purposes.
Consider a building that was purchased in 1980 for $250,000 in Koreatown and is now worth $2.4 million. Had the original owner sold it, they would have owed capital gains tax on approximately $2.15 million in gain, less depreciation recapture. You, as the heir, have a basis of $2.4 million, the current market value. If you sell it for $2.4 million, your taxable gain is zero on the appreciation (though depreciation recapture taken during the estate period applies). This is why heirs are often in a uniquely favorable position to sell: the tax cost of a sale immediately after inheriting can be dramatically lower than it would have been for the prior owner during their lifetime.
To properly document and protect the stepped-up basis, you need a qualified appraisal or broker price opinion establishing fair market value as of the date of death. This is not optional. The IRS and FTB require substantiation of the basis claim. Engage a CPA and consider a formal appraisal, particularly for properties that may have complex valuation questions such as tenant occupancy discounts, deferred maintenance, or pending code violations. A proper valuation at the outset protects your basis claim and reduces audit risk if you sell in the following years.
How Do You Get a Current Market Valuation for an Inherited Building?
Before you can make any rational decision about selling, holding, or exchanging, you need to know what the building is actually worth in the current LA multifamily market. This is not the same as what it was worth when the prior owner last had it appraised for insurance purposes, what Zillow says, or what a neighbor told you they heard another building sold for. It is a current, market-based assessment by a broker who is actively transacting in that specific submarket.
A proper multifamily valuation for an inherited LA apartment building considers: the current rent roll relative to market rents (the rent spread is often the most significant value driver in RSO buildings), the building's physical condition and any deferred maintenance that a buyer's inspection will surface, recent comparable sales in the specific submarket, the Measure ULA transfer tax exposure if the building is near or above the $5M threshold, and the buyer pool that is currently active in that neighborhood. For most inherited buildings in neighborhoods like Koreatown, Echo Park, Highland Park, or Glassell Park, the buyer pool consists of 1031 exchange buyers rolling equity from other LA buildings, institutional private equity firms pursuing value-add plays, and individual investors who have been tracking specific neighborhoods. Each of these buyer types underwrites buildings differently, and a good broker positions the asset to reach all three simultaneously.

Once you have confirmed RSO status, documented your stepped-up basis, and received a market valuation, you are in a position to make an informed decision about the building's future. There are three meaningful paths available to most heirs, each with distinct implications for liquidity, taxes, operational involvement, and long-term wealth.
The sell path provides immediate liquidity, exits all RSO and habitability obligations, and allows heirs to deploy capital elsewhere. It makes the most sense when the heir has no experience managing multifamily property, when multiple heirs have different financial needs and a buyout is not feasible, when the building requires significant capital investment to stabilize, or when the stepped-up basis means the tax cost of a sale is minimal. The hold path preserves the real estate exposure, captures ongoing cash flow and long-term appreciation, and continues to build equity as rents trend toward market through natural turnover. It requires either active management capacity or the willingness to engage professional property management, which typically costs 5% to 8% of gross rents for Los Angeles multifamily. The 1031 exchange path preserves real estate exposure while deferring any remaining gain, allowing heirs to swap a challenging LA apartment building for a different asset type: perhaps a triple-net commercial building that requires no active management, a property in a different market with lower regulatory burden, or a Delaware Statutory Trust (DST) that allows passive ownership of institutional real estate.
The table below presents the decision framework in more detail across the key criteria heirs typically weigh.
| Criteria | Sell | Hold | 1031 Exchange |
|---|---|---|---|
| Holding period intention | Short-term; want liquidity now | Long-term; 10+ years | Medium to long; want different asset |
| Tax situation | Strong: low or no capital gain due to stepped-up basis | Tax deferral not needed; income welcome | Remaining gain to defer; high-bracket taxpayer |
| Operational capacity | No management experience or interest | Willing to self-manage or hire PM company | Want passive income; no active involvement |
| Building condition | Deferred maintenance; value-add potential better for buyer | Stabilized; good occupancy; manageable repairs | Either; exchange works regardless of condition |
| Equity position | High equity; stepped-up basis; low tax cost to sell | Strong cash-on-cash return after refinance optional | Large equity stack; want to recycle into larger asset |
| Multiple heirs | Clean resolution; each heir receives cash | Requires consensus; all heirs must agree on management | Possible, but all heirs must coordinate the exchange |
| Market timing | Current buyer demand in the submarket is strong | Anticipate appreciation; willing to wait out cycle | Identify replacement before selling; market agnostic |
How Do You Sell an Inherited Apartment Building in Los Angeles?
When selling makes sense, the process for an inherited apartment building follows the same fundamentals as any LA multifamily sale, with some important nuances specific to estate situations. The first is title. Before you can close escrow, the title company will require evidence that you have the legal authority to sell. If the building was in a trust, that means the successor trustee certificate and trust documents. If the estate went through probate, it means the Order Confirming Sale or Letters Testamentary with IAEA authority. If any liens, judgments, or back taxes exist on the property from the prior owner's estate, those must be resolved before or at close. Start the title review early.
The second is the offering memorandum. A professional multifamily OM for an inherited building should honestly present the rent roll, including any below-market rents, because sophisticated buyers will discover everything in due diligence and a presentation that attempts to obscure operating reality will collapse the deal at the worst possible time. The OM should also present the decontrol analysis: unit by unit, what the market rent potential is as tenants vacate and what cap rate the building approaches at full market rents. In many LA neighborhoods, the spread between a building's current yield at in-place rents and its projected yield at full decontrol is 100 to 200 basis points or more. That spread is the value-add story, and it is what separates a correctly positioned inherited building from one that is simply dumped on the market at a number pulled from a residential comparable database.
Third, and critically for inherited buildings specifically: disclose everything. California requires comprehensive disclosures in commercial real estate transactions, and estate sellers who attempt to conceal known defects, code violations, pending LAHD orders, or tenant disputes face significant post-close liability. If the building has problems, disclose them. A buyer who knows what they are getting into will pay a price that reflects reality. A buyer who discovers problems after close will sue.

Call (323) 376-2469 Start the Sale ProcessHolding the Building: What You Inherit from the Previous Owner
Choosing to hold an inherited apartment building is not a passive decision. You are taking on an operating business with real obligations to real tenants and real regulatory exposure. Understanding what you are inheriting operationally is essential before you make this choice.
On the tenant side, you inherit every existing lease agreement at its current terms, including below-market rents on long-tenured RSO tenants who may have been in their units for 10, 15, or even 30 years. You cannot simply reset rents to market rates on these tenants while they remain in place. You also inherit any outstanding maintenance requests, any pending LAHD complaints, any ongoing disputes about security deposits, and any informal understandings the prior owner may have had with tenants that are difficult to document but create tension when a new owner tries to run things differently.
On the building side, you inherit the physical condition, which in older Los Angeles buildings often means deferred maintenance that a prior owner either could not afford to address or chose to defer. Soft-story retrofit compliance (if applicable under LADBS Ordinance 183893), any outstanding LADBS notices of violation, and the physical condition of all systems including plumbing, electrical, roofing, and HVAC become your responsibility immediately. If the building requires significant capital investment to bring into compliance, that cost affects both your cash flow analysis for holding and your net proceeds analysis for selling.
On the regulatory side, you take on annual LAHD rent registration obligations, the duty to respond to any existing LAHD cases opened against the prior owner, and the ongoing obligation to stay current with any changes to RSO enforcement rules. The 2025-2026 RSO allowable increase is 4%. If the prior owner skipped a registration year, you may not be permitted to impose that increase until registration is brought current.
If you hold, engage a professional property management company experienced with RSO compliance. A good LA multifamily PM firm will handle rent registrations, habitability response protocols, just-cause eviction documentation, and annual allowable increase letters, all of which protect your legal exposure and your ability to sell cleanly in the future. This is not a cost; it is risk mitigation that pays for itself in avoided violations and preserved asset value.
The 1031 Exchange Option: Timelines and Traps
A 1031 exchange allows you to sell your inherited apartment building and defer capital gains taxes by reinvesting the proceeds into a like-kind replacement property within a specific timeframe. For many heirs who have moderate capital gains after the stepped-up basis adjustment, a 1031 exchange is worth modeling carefully because it may allow you to swap a high-maintenance, RSO-heavy LA apartment building for a more passive asset class while preserving real estate exposure and deferring any remaining tax liability indefinitely.
The mechanics require careful attention. To execute a valid 1031 exchange: the property must be held for investment or business purposes, which inherited property satisfies from the moment you take title; you must identify your replacement property or properties within 45 calendar days of closing on the relinquished property; you must close on the replacement property within 180 calendar days of the original close; and all proceeds from the sale must be held by a Qualified Intermediary (QI), not by you or your attorney. Receiving or constructively receiving the proceeds, even for a single day, disqualifies the exchange.
For Los Angeles inherited apartment buildings, the most common 1031 replacement options are: other California apartment buildings in less regulated markets (though AB 1482 now covers a wide range of properties statewide), triple-net leased commercial properties (pharmacies, fast food, medical offices) that provide passive income with minimal management demands, industrial or warehouse properties in the Inland Empire or Central Valley which have performed strongly in recent years, and Delaware Statutory Trust interests, which allow heirs to invest exchange proceeds into fractional ownership of institutional real estate managed by a professional sponsor with no active management responsibility. Each carries a different risk profile and management burden. The qualified intermediary agreement must be in place before the inherited building closes escrow, since the 45-day identification window opens the moment title transfers and there is no grace period once escrow closes.
Measure ULA: The Transfer Tax That Changes Your Math Above $5M
Measure ULA, passed by Los Angeles voters in November 2022 and codified in LA Municipal Code Section 21.9.2, imposes an additional transfer tax on sales of real property located within the City of Los Angeles that exceed the threshold amounts. A sale between $5 million and $10 million incurs an additional 4% transfer tax. A sale above $10 million incurs 5.5%. This is paid by the seller at close and comes out of net proceeds.
There is no exemption for inherited properties. The tax applies to any seller, including estates, successor trustees, and individual heirs who have taken title through inheritance. If the building you inherited is worth between $5M and $10M and is located within the City of LA, Measure ULA will cost you between $200,000 and $400,000 at sale. On a building worth $7M, that is a $280,000 tax that did not exist before 2023. This fundamentally changes the net proceeds calculation for any inherited building near or above the threshold.
Sale price $4.5M, City of LA: No ULA tax (below $5M threshold). Standard city/county transfer tax applies.
Sale price $6M, City of LA: ULA tax = $240,000 (4%). Net proceeds reduced by $240,000 versus what they would have been in 2022.
Sale price $8M, City of LA: ULA tax = $320,000 (4%). This alone can determine whether a sale proceeds or whether a different strategy is adopted.
Sale price $11M, City of LA: ULA tax = $605,000 (5.5%). Combined with standard transfer taxes, the total transfer tax burden exceeds $650,000.
For buildings with valuations near $5M, a precise current-market analysis is important. A building that appraises at $5.1M carries full ULA exposure. A building that can be credibly positioned at $4.95M avoids it entirely. The difference is $200,000. A broker who understands Measure ULA will position the pricing discussion with this threshold in mind, not as a manipulation of the process but as a legitimate market assessment that reflects how buyers are also structuring their offers.
Buildings in municipalities outside the City of Los Angeles boundaries, such as Culver City, West Hollywood, Santa Monica, or unincorporated LA County, are not subject to Measure ULA. If your inherited building is in an unincorporated area or an independent municipality, confirm its exact jurisdictional location before assuming ULA applies.
Should You Work with an Estate Attorney or a Multifamily Broker?
Heirs who inherit apartment buildings in Los Angeles often find themselves working with an estate attorney first and a real estate broker second, with the two professionals operating in parallel for most of the process. Understanding what each professional is responsible for prevents confusion, missed deadlines, and costly errors.
The estate attorney or successor trustee attorney handles the legal authority to transact: obtaining or confirming trust successor status or probate authority, clearing title issues, resolving any creditor claims against the estate, handling IRS and FTB estate tax and income tax obligations, and coordinating the final distribution of sale proceeds among beneficiaries. If the estate has multiple heirs who disagree about the sale, the estate attorney manages that dispute, which may ultimately require a court-supervised sale proceeding. The estate attorney is not, in most cases, a real estate expert. They should not be your source of market value information, buyer qualification guidance, or marketing strategy.
The multifamily broker handles everything on the real estate side: the market valuation, the preparation of an offering memorandum, the identification and qualification of buyers, the negotiation of price and terms, the management of due diligence, and the coordination with escrow and title to close. A broker experienced with estate sales understands that the seller's authority may be in process, that probate court may need to confirm the sale, and that the timeline may be constrained by legal requirements outside the broker's control. A broker who does not have this experience will create problems rather than solve them.
The tax advisor, typically a CPA, sits in the middle: they must be consulted before any sale to confirm the stepped-up basis calculation, determine whether a 1031 exchange makes sense given the remaining gain, model the California FTB 3.33% withholding obligation (which applies to sales by most California taxpayers including estates), and confirm the depreciation recapture exposure. Engaging the tax advisor before signing a listing agreement, rather than after, ensures that the sale strategy is tax-optimized from the start.

Frequently Asked Questions
What do I do first if I inherited an apartment building in Los Angeles?
Your first three actions are: (1) confirm RSO coverage by checking the building's construction date against LAMC Chapter XV criteria, (2) engage a CPA to document the stepped-up cost basis under IRC Section 1014, and (3) determine whether the property passed through a trust or will require California probate. If the building was not held in a trust, probate may delay your ability to sell for nine to eighteen months. Tenant obligations begin immediately regardless of probate status.
Do I have to keep the existing tenants after inheriting an LA apartment building?
Yes. An ownership transfer does not constitute just cause for eviction under the Los Angeles Rent Stabilization Ordinance. Tenants in RSO-covered buildings have just-cause protections that survive the sale or transfer of the building. You inherit all existing lease agreements, all RSO obligations including annual allowable rent increases, and all habitability responsibilities from the first day you take title. Evicting tenants simply because you are the new owner is not permitted under LAMC Chapter XV.
What is stepped-up basis and how does it help heirs?
When you inherit real property, IRC Section 1014 resets the cost basis to the fair market value at the decedent's date of death. This eliminates capital gains tax on all appreciation that occurred during the prior owner's lifetime. If your relative purchased the building for $200,000 in 1985 and it was worth $1.8M at death, your basis is $1.8M. A sale at $1.9M produces only $100,000 in taxable gain rather than $1.7M. The stepped-up basis is one of the most valuable tax advantages available to heirs, and it is only available at inheritance. Consult a CPA immediately to document it properly.
Should I sell or keep an inherited apartment building in Los Angeles?
The right path depends on four factors: your holding period intentions, your capacity to manage or hire management for an RSO property, your tax situation relative to the stepped-up basis window, and your equity position. Heirs with no intention to actively manage multifamily assets, no prior landlord experience, and immediate liquidity needs typically benefit from selling. Heirs with long-term wealth-building goals and the bandwidth to oversee operations often hold. The 1031 exchange is appropriate when you want to maintain real estate exposure but transition to a different asset type or geography.
Can I do a 1031 exchange with an inherited apartment building?
Yes, an inherited apartment building can be used as the relinquished property in a 1031 exchange, but only after you formally take title. The estate must distribute the asset to you first. Once you hold title, the standard 1031 rules apply: 45 days to identify replacement properties and 180 days to close. All proceeds must flow through a Qualified Intermediary. The stepped-up basis at the date of death becomes your basis for calculating gain deferred in the exchange.
Does Measure ULA apply to inherited apartment buildings in LA?
Yes. Measure ULA, codified in LA Municipal Code Section 21.9.2, applies to all sales of real property in the City of Los Angeles above the threshold amounts, regardless of how the seller acquired the property. A sale between $5M and $10M incurs a 4% additional transfer tax; sales above $10M incur 5.5%. There is no exemption for inherited properties. On a $6M sale, ULA adds $240,000 in transfer taxes that come directly out of your net proceeds.
How long does it take to sell an inherited apartment building in Los Angeles?
If the building was held in a trust, the successor trustee can typically list and sell within 60 to 120 days of death, comparable to a standard multifamily sale. If the estate goes through California probate, add nine to eighteen months before you can close. The sale process itself, once you have authority to sell, typically runs 45 to 90 days from listing to close, depending on occupancy, building condition, and buyer financing. Estates with multiple heirs may add additional time if beneficiaries disagree on pricing or terms.
What if the inherited building has problem tenants or deferred maintenance?
Problem tenants and deferred maintenance are common in inherited buildings where the prior owner was aging or disengaged. As the new owner, you assume liability for habitability and code compliance from day one. A multifamily broker experienced with estate sales will help you determine whether to cure problems before listing or to position the building as a value-add sale priced accordingly. Attempting to evict problem tenants immediately before a sale is rarely advisable and often backfires under RSO rules. In most cases, the market prices in deferred maintenance, and a properly disclosed as-is sale is cleaner than an attempted renovation.
Do I need a specialized broker to sell an inherited apartment building in LA?
Yes. Selling an inherited LA apartment building requires a broker who understands RSO just-cause eviction requirements, how to calculate the decontrol uplift premium in an offering memorandum, Measure ULA threshold analysis, and how to present an estate sale to the institutional and private capital buyers who are the most qualified purchasers in this market. A residential broker or general commercial broker without specific LA multifamily depth will almost always leave significant value on the table or create due diligence problems that delay or kill the transaction.
