Forty-six of our published deal stories involve rent control or another regulation that shaped the sale: who the buyers were, how the building was underwritten, or how long escrow took. This article draws on those stories. It describes what we saw in those deals; it does not measure what any regulation did to prices across the market.
For every local cap's current figure, the buildings it covers and what is changing, see our rent control guide for Los Angeles, Ventura and Santa Barbara.
The Rules Behind Our Deals
Los Angeles apartment owners work under several layers of rules, and new ones have been added since 2019. The ones that come up most in our deals are:
Los Angeles RSO (Rent Stabilization Ordinance)
Covers rental properties of two or more units first built on or before 10/01/1978 in the City of Los Angeles: 661,851 units in the City Controller's 2024 count. Annual rent increases are capped at 3% from 07/01/2026 through 06/30/2027 (the same 3% rate has applied since 07/01/2025). Since 02/02/2026 the formula is 90% of CPI, with a 1% minimum and a 4% maximum. Utility percentage adders were eliminated, and the 10% dependent adder is no longer permitted. Vacancy decontrol under Costa-Hawkins still allows landlords to reset rents to market when a tenant voluntarily vacates. Buyers therefore underwrite two things: the rent the building collects today and the rent a unit could reach after a tenant leaves. Our RSO guide covers the full mechanics.
AB 1482 (California Tenant Protection Act)
A statewide cap of 5% plus regional CPI, up to 10% a year, with just-cause eviction protections, on most rental buildings whose certificate of occupancy is more than 15 years old (a rolling date), through 01/01/2030. It reaches buildings in cities with no local cap, including many of our deals in Glendale, Burbank, Long Beach and most of Ventura County. Santa Monica has had its own rent control since 1979, and Thousand Oaks’ 1980 ordinance now covers only tenancies in place since 1987, so its newer tenancies also fell under AB 1482. Buildings that once had no cap now have one, and buyers underwrite it.
Measure ULA (Homelessness and Housing Solutions Tax)
A 4% transfer tax on sales over $5,400,000 and under $10,900,000 (CPI-adjusted), and 5.5% on sales of $10,900,000 or more, in the City of Los Angeles. Our ULA guide details how it affects pricing and deal structuring. For LIHTC and affordable housing properties, exemptions may apply, but the application process adds weeks to the escrow timeline.
LIHTC (Low-Income Housing Tax Credit)
Properties with active LIHTC restrictions face a completely different sales process: TCAC transfer approval, right-of-first-refusal obligations, extended-use covenant compliance, and a specialized buyer pool limited to operators who understand affordable housing compliance. Our Serrano deal, a 42-unit LIHTC property that closed after 239 days and three simultaneous government approvals, demonstrates the complexity involved.
What We Saw in These Deals
Regulation Comes Up in the Decision to Sell
In many of these deals the seller named a regulation among the reasons to sell: rent limits, compliance costs, a soft-story retrofit order or Measure ULA. We have not counted how often it was the main reason, and owners sell for many reasons at once.
Owners who bought decades ago often raise it: an owner who purchased in 1990 now works under statewide caps, possible ULA exposure and retrofit orders that did not exist then. Some of them sell and use a 1031 exchange to move into a market with fewer rules or a passive investment.
Some Buyers Underwrite the Rules Better Than Others
Not every buyer understands LA's regulatory environment. Out-of-state investors routinely underestimate rent control implications. First-time buyers may not account for RSO relocation fees or soft-story compliance costs. Measure ULA's transfer tax changes the math for buyers and sellers above the threshold.
In a regulated market, the broker's job is not just finding a buyer. It is finding a buyer who understands what they are buying and can underwrite the regulatory constraints accurately. Selling a rent-controlled building to a buyer who does not understand vacancy decontrol mechanics is a recipe for a failed escrow.
Government Approvals Can Lengthen Escrow
Government approvals do not move on real estate timelines. TCAC transfer applications, ULA exemption filings, and RSO compliance verifications all add weeks or months to the escrow process. Fourteen of these 46 deal stories also appear in our "Escrows That Almost Didn't Close" category.
How Buyers Underwrite Below-Market Rents
In City of Los Angeles buildings we underwrote from 2016 to 2026, rent-controlled units sat about 9 points further below our market-rent estimate than exempt units of similar age, and, in the buildings whose rent rolls show move-in dates, the gap widened the longer a tenant had stayed. That result rests on our own underwriting files, one source, and is detailed in our rent control guide for Los Angeles, Ventura and Santa Barbara. Our own test did not establish whether rent control raises or lowers a building's price.
A buyer looking at a building with deep loss to lease weighs two things: today's income and the rent a unit can reach when a tenant moves out. How much of that future rent a buyer will pay for depends on the buyer, the building and interest rates; in our experience it shows up in the cap rate on current income.
In our view, pricing a rent-controlled building on current income alone or on full market rents alone both miss. We price it on the rent roll as it is, with in-place and market rents side by side and move-in dates, so a buyer can underwrite the turnover they expect.
What Sellers in Regulated Markets Should Know
- Your building's regulatory status affects every aspect of the sale, from pricing methodology to buyer pool to escrow timeline. Get a regulatory audit before listing.
- Show the gap between in-place and market rents. Buyers underwrite turnover; document current rents, market rents and move-in dates clearly in the offering.
- AB 1482 compliance is now table stakes. Ensure your property is in full compliance before listing. Non-compliance creates escrow risk and buyer leverage.
- Measure ULA on sales over $5,400,000 changes the math. If your property is near the threshold, pricing strategy must account for the 4% transfer tax. Some deals are better priced just below the threshold.
- Budget extra time for LIHTC and affordable housing sales. Government approvals can add 3 to 6 months to the timeline. Structure the escrow to accommodate this.

Frequently Asked Questions
How does rent control affect apartment building values in Los Angeles?
Our own test of cities that adopted caps from 2017 to 2023 did not establish a price effect either way; the design could not detect an effect smaller than about 5% to 8%. What we did find, in City of Los Angeles buildings we underwrote, is that rent-controlled units sit further below our market-rent estimate, and, where rent rolls show move-in dates, more so the longer the tenant has stayed. Buyers price that gap building by building.
What is Measure ULA and how does it affect apartment sales?
Measure ULA imposes a 4% transfer tax on sales over $5,400,000 and under $10,900,000, and 5.5% on sales of $10,900,000 or more in the City of Los Angeles.
Does AB 1482 apply to my building?
AB 1482 applies to most rental buildings in California whose certificate of occupancy is more than 15 years old, with exemptions for single-family homes and condos owned by individuals who give the required notice, owner-occupied duplexes, and units under a local cap that is lower. Our rent control guide for Los Angeles, Ventura and Santa Barbara has a checker for every city in Los Angeles, Ventura and Santa Barbara counties.
How long does it take to sell a LIHTC property?
LIHTC transactions typically take 6 to 12 months due to TCAC transfer approval requirements, right-of-first-refusal obligations, and a specialized buyer pool. Our Serrano deal took 239 days from listing to close.
