How to Underwrite a California Rental Property with Measure ULA and AB 1482

Underwriting a California rental property requires two calculations that most national real estate frameworks do not account for: the Measure ULA exit liability (if the property is in the City of Los Angeles or adjacent municipalities) and the AB 1482 rent cap ceiling (which sets the maximum annual rent increase for the life of the tenancy if the property is not exempt). Getting either calculation wrong can turn a profitable-looking deal into a net-negative investment. Here is a systematic approach to underwriting that incorporates both.

Step 1: Determine the AB 1482 Exemption Status First

Before modeling any rent increase assumptions, establish whether the property is subject to AB 1482 rent caps. This step must come first because it determines the maximum revenue growth you can underwrite.

The exemption decision requires answering three questions in sequence:

Question 1: Was the property completed within the last 15 years? AB 1482 provides a rolling 15-year exemption for newly constructed units. In 2026, any property with a certificate of occupancy issued after 2011 is currently exempt from the statewide rent cap on that basis. A 2015-built Sacramento duplex remains exempt through 2030. A 2012-built Long Beach fourplex became subject to AB 1482 in 2027. Note the rolling nature: this exemption expires for each property on a specific date, so your underwriting model must account for when a new-construction exemption lapses.

Question 2: If not exempt by age, is it a separately alienable single-family home or condo owned by an individual or non-REIT LLC? Single-family homes and condos owned by individuals or non-REIT LLCs are conditionally exempt from AB 1482 regardless of age. Multi-family properties (duplexes, triplexes, fourplexes, apartment buildings) are generally subject to the rent cap unless protected by the new construction exemption above.

Question 3: Has the required written notice been served? Even if the property qualifies under Questions 1 or 2, the exemption is not automatic. California Civil Code §1946.2(e) requires the landlord to provide specific written notice to the tenant that the property is exempt from AB 1482's rent and eviction restrictions. Failure to serve this notice — using the exact statutory language — nullifies the exemption. A single-family home that would otherwise be exempt becomes fully subject to AB 1482 rent caps and just-cause eviction requirements if the §1946.2(e) notice was never served.

If the property is AB 1482-exempt: your rent increase underwriting can model market rent increases, subject only to the market and any local rent control overlay (see Step 2).

If the property is AB 1482-covered: the maximum annual rent increase is 5% plus the regional CPI, subject to a 10% absolute ceiling. For underwriting purposes, use the current county cap:

Conservative underwriting should model at 5.0-6.0% annual rent increases, not the ceiling, because CPI fluctuates and the ceiling in lower-inflation years may be as low as 5.5-6.5%.

Step 2: Check for Municipal Rent Control Overlays

AB 1482 is the floor, not the ceiling, for California rent regulation. Certain cities impose stricter local rent control ordinances that cap rent increases below the statewide AB 1482 maximum. If the property is in one of these cities, the local cap governs — AB 1482 does not override the stricter local law:

• Los Angeles (RSO-covered units): Annual rent increases limited to 4% under the Rent Stabilization Ordinance for RSO-covered buildings (generally pre-1978 construction). AB 1482's 8.0% cap is irrelevant for RSO-covered units.
• San Francisco: Covered units (generally pre-1979 construction) are subject to the SF Rent Ordinance, which historically allows increases in the 1.6-3.5% range — far below the AB 1482 6.3% maximum.
• Berkeley: Covered units face even tighter constraints. The Berkeley Rent Ordinance has historically allowed increases in the 1-2% range for covered units.
• Santa Monica: Covered units (generally pre-1979) face Santa Monica Rent Control Board caps, typically 1-2% annually.
• West Hollywood: Similar pre-1979 construction coverage with low annual cap adjustments.
• Oakland: Covered units under the Oakland Just Cause for Eviction Ordinance.

For properties in these cities, your rent growth underwriting must use the local ordinance cap for covered units, not the AB 1482 statewide maximum.

Step 3: Model the True Operating Expense Stack

California properties carry operating expenses that frequently do not appear in seller pro formas. A complete operating expense model for an income property in California must include:

Property taxes after reassessment. The purchase triggers a Proposition 13 reassessment to current market value. If the seller's operating statement shows $4,200 in annual property taxes on a $600,000 assessed value from 1997, and you are buying at $1.8 million, your post-purchase property tax is approximately $18,000-$20,000 annually (1% of purchase price plus applicable Mello-Roos and special assessments). Mello-Roos districts in newer California developments can add $2,000-$10,000 annually to the baseline property tax.

Insurance — the California fire zone reality. Standard homeowner and landlord policies are increasingly unavailable or unaffordable in California fire hazard zones. The FAIR Plan (insurer of last resort) covers fire damage only; a Difference in Conditions (DIC) policy is required for liability and other perils not covered by FAIR. FAIR Plan premiums in fire-hazard designated zones run 2-5x the cost of standard coverage. Before underwriting any California property in a wildfire zone, obtain current insurance quotes — do not use the seller's historical insurance premium.

LLC franchise tax. If you hold the property through an LLC, California's $800 annual minimum franchise tax is a fixed operating expense. Budget it as a line item rather than treating it as a one-time cost.

Mandatory seismic and SB 721/326 compliance. Soft-story seismic retrofit costs for multi-family properties range from $3,000-$7,000 for single-family conversions to $158,500 for large apartment buildings. SB 721/326 balcony inspection compliance (the January 2026 deadline has passed) for non-compliant properties accumulates $100-$500 daily in fines until inspection and any required repairs are completed. Always verify SB 721/326 compliance status before closing.

Property management (required for out-of-state investors). California's regulatory complexity — Section 8 voucher acceptance under SB 329, AB 12 security deposit rules, just-cause eviction requirements, habitability standards — makes self-management from another state operationally hazardous. Professional property management typically costs 8-12% of gross rents plus leasing fees.

Vacancy and bad debt. California's Unlawful Detainer eviction timeline — 4-6 weeks uncontested, 2-3 months contested — means that vacancy between tenancies and the income gap during an eviction are longer than in most other states. Budget 7-10% vacancy and include a line item for eviction reserves ($1,500-$2,500 uncontested, $4,000-$10,000+ contested).

Step 4: Model the Exit — Measure ULA and Transfer Tax Matrix

This is the step where most California investment property analyses fail. The exit cost determines your true return on invested capital, and California's transfer tax landscape — particularly in the City of Los Angeles — is dramatically different from the $1.10/$1,000 county baseline that national investing models assume.

Measure ULA (City of Los Angeles):

• Properties selling for $5,000,000 to $9,999,999: additional 4.0% tax on the gross sale price
• Properties selling for $10,000,000 or more: additional 5.5% tax on the gross sale price
• The tax applies to the gross sale price with no deduction for outstanding debt or mortgage balances
• There is no marginal rate structure: a sale at $4,999,999 incurs zero ULA tax; a sale at exactly $5,000,000 incurs $200,000 in ULA tax

The equity impact of Measure ULA: A $6 million Los Angeles building with a $4.5 million mortgage produces $1.5 million in equity. The Measure ULA tax is 4.0% × $6,000,000 = $240,000. The seller nets $1,500,000 − $240,000 = $1,260,000, before standard county transfer tax and closing costs. The ULA tax alone consumes 16% of the equity position.

The critical underwriting implication: If you are buying a Los Angeles property today at $3 million with the expectation that it will appreciate to $5.5 million over 10 years, your exit model must include a $220,000 Measure ULA liability that your current purchase-price model does not trigger. Build the projected exit price into your Measure ULA calculation before evaluating the deal.

Transfer tax matrix for other California cities:

For all properties, add the baseline county documentary transfer tax: $1.10 per $1,000 of gross sales price (0.11%).

Step 5: Account for FTB Capital Gains at Exit

California taxes all capital gains — short-term and long-term — as ordinary income at rates up to 13.3% for high earners. There is no preferential long-term capital gains rate equivalent to the federal preferential rate.

Form 593 withholding at closing: If you are a non-California resident seller, the buyer is required to withhold 3.33% of the gross sale price at closing. This is a cash flow impact at closing — you recover it through your California return — but it is a withholding, not an additional tax. Budget the cash flow timing impact.

1031 exchange and FTB Form 3840: If you plan to exit via a 1031 exchange into a property in another state, California's FTB Form 3840 clawback obligation means the deferred California gain follows you until you cash out in a taxable transaction. Model this as a contingent liability that reduces your effective after-tax return if you eventually sell without another qualifying exchange.

Cost segregation and depreciation recapture: Depreciation recapture is taxed as ordinary income in California, same as all other capital gains. If you have taken accelerated depreciation through cost segregation, the recapture calculation is material and should be modeled with your CPA before acquisition.

Who This Is For

This underwriting framework is for investors who:

• Are under contract on a California income property and need to verify that the deal's return projection holds after accounting for the actual rent cap ceiling for the property's county, the applicable transfer tax at their projected exit price, and the true operating expense stack including post-reassessment property taxes
• Are evaluating a Los Angeles multi-family property above $4 million and need to determine whether the deal's exit is viable after Measure ULA
• Are modeling rent growth assumptions on existing tenanted properties and need to confirm whether the property is AB 1482-exempt and, if so, whether the §1946.2(e) exemption notice has been served

Who This Is NOT For

This framework does not replace:

• A California CPA for entity-specific tax strategy and cost segregation analysis
• A California real estate attorney for §1946.2(e) notice review and AB 1482 compliance documentation
• A current market broker for submarket-specific rent data and vacancy rate inputs

Frequently Asked Questions

How do I find out if a property is in an LA RSO-covered building?

The City of Los Angeles Housing Department maintains the RSO registration database at the Los Angeles Housing Department portal. You can search by property address to determine RSO status. Generally, multi-family buildings constructed before October 1, 1978 in the City of Los Angeles are subject to RSO, but you must verify the specific property's registration status.

Can I model the Measure ULA cost as a pass-through to the next buyer?

Market pricing will determine whether Measure ULA costs can be passed through at sale. In practice, buyers at the $5-10 million price point have incorporated Measure ULA into their own underwriting, which has compressed pricing in the City of Los Angeles above the $5 million threshold. RAND Corporation research estimated the tax was suppressing approximately 1,900 units of new construction annually by reducing the economics of land sales and multi-family trade.

What happens if I buy a new construction property and the 15-year AB 1482 exemption expires during my hold?

When the rolling 15-year new construction exemption expires for a property you own, the property becomes subject to AB 1482 automatically — including the rent cap and just-cause eviction requirements. The §1946.2(e) written notice requirement for the exemption is only relevant during the period of exemption. Once the exemption expires, you need to serve appropriate just-cause eviction notices and apply the AB 1482 rent cap to future increases.

Is the Measure ULA tax expected to be repealed?

As of mid-2026, Measure ULA is active and enforced. There have been legal challenges arguing the tax exceeds California's authority under the Mitigation Fee Act, but no court has struck it down as of this writing. Underwrite your California Los Angeles properties assuming Measure ULA remains in place at exit.

How should I model potential rent growth for properties currently at below-market rents?

AB 1482-covered properties allow rent increases up to the applicable CPI cap upon renewal, not to market rent. If you acquire a property where current rents are 30% below market, you cannot increase rents to market in one step — you are limited to the annual cap each year. This significantly extends the time horizon to reach market rent and should be modeled year by year in your cash flow projections.
