Most multifamily property owners in Los Angeles think about capital improvements in terms of cost. The retrofit is an expense. The panel upgrade is an expense. The balcony repair is an expense. These are obligations to be managed, budgeted, and absorbed — necessary costs of ownership that don't generate revenue and don't improve the property's income profile in any direct way.

That framing is incomplete — and the incompleteness is costing owners real money.

California's Tenant Protection Act of 2019 — AB 1482 — includes a capital improvement pass-through mechanism that allows landlords to recover a portion of the cost of qualifying capital improvements through rent increases on covered tenants. It is one of the least-discussed provisions of a law that is extensively discussed in almost every other respect. Most multifamily owners know AB 1482 as the framework that caps annual rent increases. Far fewer know it as the framework that explicitly provides a pathway to exceed those caps for qualifying capital improvement investments.

The improvements that qualify include exactly the work that SKS Construction delivers: seismic retrofits, electrical system upgrades, structural repairs, and other capital improvements that extend the useful life of the building or bring it into compliance with applicable codes.

Here is how the pass-through mechanism works, what qualifies, what the process requires, and how property owners can structure capital improvement projects to maximize their recovery under AB 1482 — legally, documentably, and in compliance with California's tenant protection framework.

AB 1482 Basics — Who It Covers and What It Allows

AB 1482 applies to most residential rental units in California that are not otherwise covered by local rent control ordinances — and, critically, it applies to units in cities that have local rent control as a supplemental framework for units that the local ordinance doesn't cover. In Los Angeles, the interaction between AB 1482 and the City's Rent Stabilization Ordinance creates a layered compliance framework that owners need to understand before applying any rent increase mechanism.

The general AB 1482 framework caps annual rent increases at 5% plus the local Consumer Price Index, with a maximum of 10%. This is the provision that most owners know. The capital improvement pass-through — Civil Code Section 1947.3 and the implementing regulations — is the provision that allows owners to apply for rent increases that exceed this cap when qualifying capital improvements have been made to the property.

The pass-through is not automatic. It is not unlimited. And it is not available to every property owner or for every type of improvement. The specific eligibility requirements, the calculation methodology, and the procedural requirements vary between the state AB 1482 framework and any local ordinance that applies to the property. In Los Angeles, the RSO has its own capital improvement pass-through program with its own rules — and for RSO-covered units, the RSO program governs rather than the AB 1482 framework.

Understanding which framework applies to your specific units — AB 1482, the LA RSO, another local ordinance, or none — is the first step in evaluating whether a capital improvement pass-through is available and what it can produce.

Which Properties Are Covered — The Threshold Questions

The AB 1482 capital improvement pass-through applies to residential rental units that meet all of the following conditions:

The unit is in a building that was issued a certificate of occupancy more than 15 years ago. New construction is exempt from AB 1482 entirely — the 15-year rule is the threshold that brings a building into the AB 1482 framework.

The unit is not otherwise exempt from AB 1482. Single-family homes and condominiums are exempt from AB 1482 if the owner provides the required exemption notice. Certain subsidized housing units are exempt. Units in buildings where the owner and tenant share common hallways or common walls — owner-occupied duplexes and some triplexes — may be exempt.

The unit is not covered by a more restrictive local rent control ordinance. In Los Angeles, units built before October 1, 1978 — which is the threshold for RSO coverage under the LA Rent Stabilization Ordinance — are covered by the RSO rather than AB 1482 for most purposes. The RSO has its own capital improvement pass-through program, and RSO-covered units use that program rather than the AB 1482 framework.

For most multifamily properties in Los Angeles built between 1978 and approximately 2008 — the building vintage that is most commonly subject to soft-story retrofit requirements, panel upgrade needs, and SB 721 balcony repair obligations — AB 1482 is the applicable framework. These buildings are old enough to be in the AB 1482 window, new enough to have missed RSO coverage, and exactly the building vintage that is facing the largest concentration of capital improvement obligations in the current regulatory environment.

What Qualifies as a Capital Improvement for Pass-Through Purposes

The AB 1482 framework defines qualifying capital improvements as permanent improvements or betterments that materially add to the value of the property, appreciably prolong its useful life, or adapt it to new uses — as distinguished from ordinary repairs and maintenance that merely keep the property in its existing condition.

This distinction matters — and it works in the property owner's favor for most of the improvements in SKS's scope of work.

Soft-story seismic retrofits are capital improvements. They are permanent structural modifications that materially extend the useful life of the building and bring it into compliance with a mandatory code requirement. The retrofit does not merely maintain the building in its existing condition — it fundamentally changes its structural performance under seismic loading. This is the paradigmatic capital improvement for pass-through purposes.

Electrical panel and service upgrades are capital improvements. A service upgrade from 100 amps to 200 or 400 amps is not routine maintenance of an existing electrical system. It is a permanent upgrade that increases the building's electrical capacity and extends the useful life of the electrical infrastructure. The upgrade is permanent, structural, and qualifies as a capital improvement under both the AB 1482 framework and the LA RSO capital improvement program.

Balcony structural repairs under SB 326 and SB 721 occupy a more nuanced position. Routine maintenance and ordinary repairs — replacing a few deteriorated deck boards, applying waterproof coating — are generally not qualifying capital improvements. Structural framing replacement, ledger board reconstruction, and diaphragm connection upgrades — the kind of structural repair that an SB 326 or SB 721 finding requiring significant intervention produces — are more likely to qualify as capital improvements, particularly when the scope is documented by a licensed engineer and permitted through LADBS.

Foundation repairs and structural retrofits — retaining wall reconstruction, caisson additions, grade beam work, CMU reinforcement — are capital improvements. They are permanent structural modifications that extend the useful life of the building and are not routine maintenance by any reasonable definition.

The documentation of the improvement as a capital improvement — the engineering drawings, the LADBS permit, the final inspection record, and the engineer's certification — is the evidentiary foundation for the pass-through application. Work that is performed without permits, without engineering documentation, and without city sign-off is harder to characterize as a qualifying capital improvement — because the documentation that establishes its character as a permanent, engineered, code-compliant improvement doesn't exist.

This is one of the less-obvious financial reasons why permitted, engineered construction matters for multifamily property owners: the permit documentation is not just a compliance record. It is the evidence base for rent increase applications that can generate ongoing revenue from the capital investment.

The LA RSO Capital Improvement Pass-Through — For Pre-1978 Buildings

For multifamily property owners with RSO-covered units — buildings with certificates of occupancy issued before October 1, 1978 — the relevant mechanism is the LA Rent Stabilization Ordinance's Capital Improvement Pass-Through program rather than the AB 1482 framework. The RSO program has been in place for decades and has a well-established procedural framework administered by the Los Angeles Housing Department.

Under the RSO capital improvement pass-through, an owner who has completed qualifying capital improvements can apply to LAHD for permission to collect a temporary rent surcharge from covered tenants. The surcharge is calculated based on the total cost of the qualifying improvement, allocated across all covered units, amortized over a defined period — typically three to five years depending on the nature of the improvement.

The RSO pass-through is explicitly designed to allow owners to recover the cost of improvements that benefit the tenant — not to generate profit from the improvement, but to recover the capital cost in a way that is transparent, documented, and approved by the housing department. The application requires detailed documentation of the improvement scope, the total cost, the contractor information, and the permit records.

For a 12-unit RSO building that has completed a $180,000 soft-story retrofit, the pass-through calculation might work as follows: $180,000 total cost, allocated across 12 units at $15,000 per unit, amortized over 60 months at $250 per unit per month in temporary rent surcharge. The surcharge is temporary — it terminates after the amortization period — and it is in addition to the standard annual RSO rent increase allowance.

The pass-through does not make the retrofit free. It makes it partially recoverable through the rent roll — converting a pure capital expense into a capital investment with a defined recovery period.

The AB 1482 Pass-Through Mechanics — For Post-1978 Buildings

For units covered by AB 1482 rather than the RSO — buildings with certificates of occupancy issued between October 1978 and approximately 2008, depending on the specific building — the capital improvement pass-through mechanics are different from the RSO program but conceptually similar.

Under AB 1482, a landlord may increase rent above the standard annual cap if the increase is based on a capital improvement that meets the qualifying criteria. The increase is subject to specific limitations: the rent increase for a capital improvement cannot exceed 10% of the current rent, and the total rent increase in any 12-month period — including any standard annual increase — cannot exceed 15% of the rent in effect at the start of that period.

The AB 1482 capital improvement pass-through does not require pre-approval from a housing agency — unlike the RSO program, which requires LAHD application and approval before the surcharge can be collected. Under AB 1482, the landlord provides required notice to the tenant of the rent increase, documents the capital improvement basis for the increase, and implements the increase in compliance with the notice requirements.

However — and this is critical — the absence of pre-approval does not mean the absence of scrutiny. A tenant who challenges the AB 1482 capital improvement pass-through can file a complaint with the appropriate housing department or pursue the matter through the courts. The landlord must be able to document the qualifying nature of the improvement, the cost basis for the pass-through calculation, and the proper notice procedures.

The documentation that makes this defense possible is exactly the documentation that a properly permitted, engineered, and city-signed-off construction project produces: the LADBS permit, the stamped engineering plans, the final inspection record, the contractor invoices, and the engineer's certification. Work performed without this documentation trail cannot be defended as a qualifying capital improvement — because the evidence that establishes its qualifying character doesn't exist.

The Notice Requirements — What Has to Happen Before the Rent Increase

Both the RSO pass-through and the AB 1482 pass-through have notice requirements that must be satisfied before any rent increase based on a capital improvement can be collected. Failure to comply with notice requirements — in timing, content, or delivery method — can render an otherwise valid pass-through unenforceable and expose the owner to penalties for collecting rent in excess of the applicable limit.

Under the RSO program, the notice process is administered by LAHD as part of the application process. LAHD reviews the application, approves the pass-through amount, and the owner then provides required notice to tenants of the approved surcharge before it can be collected.

Under AB 1482, the owner must provide written notice to the tenant at least 30 days before any rent increase of 10% or less, and at least 90 days before any rent increase exceeding 10%. The notice must state the amount of the new rent, the effective date of the increase, and — for a capital improvement basis — should document the capital improvement that justifies the increase.

The notice requirements are procedural — they don't affect the substantive validity of the pass-through, but they are a prerequisite for collecting the increased rent. Property owners who implement rent increases based on capital improvements without following the notice procedures are collecting unauthorized rent — even if the underlying improvement would have qualified for the pass-through.

The recommendation: work with a qualified property management attorney or housing consultant who is familiar with the applicable notice requirements for your specific units before implementing any capital improvement pass-through rent increase. The procedural requirements are not complicated, but they need to be followed correctly.

The Project Sequencing That Maximizes Pass-Through Recovery

Here is the practical insight that most property owners don't receive from either their contractor or their property manager: the sequence and documentation of the capital improvement project directly affects the amount recoverable through the pass-through mechanism.

Capital improvement pass-through calculations are based on the total documented cost of the qualifying improvement. Total documented cost means the sum of all costs that can be substantiated with records — contractor invoices, engineering fees, permit fees, inspection fees, and directly related project costs. Costs that are not documented are not recoverable through the pass-through.

This means that every fee associated with a qualifying capital improvement project should be documented and retained: the SKS design and engineering fee, the permit application fees, the LADBS plan check fees, the special inspection fees, the contractor construction cost, and any directly related costs such as temporary tenant relocation expenses where applicable. The total of these documented costs is the basis for the pass-through calculation — and maximizing the documented total maximizes the recoverable pass-through.

It also means that improvements should be permitted — because the permit record is the primary documentation of the improvement's qualifying character, and unpermitted improvements have a weaker basis for pass-through qualification. An electrical panel upgrade completed with a finaled LADBS permit and a licensed engineer's sign-off is a documented qualifying capital improvement. The same upgrade performed without a permit is an undocumented modification that is difficult to defend as a qualifying improvement if challenged.

SKS's standard project deliverable — the complete permit documentation package including the finaled permit, stamped engineering plans, final inspection record, and engineer certification — is not just a compliance record. It is the pass-through documentation package. Every project we complete for a multifamily owner is delivered with the documentation that supports a capital improvement pass-through application.

What This Means for the All-In Return on a Capital Improvement

The financial analysis of a capital improvement project changes when the pass-through mechanism is factored in. The improvement is not simply an expense — it is an investment with a defined recovery component through the rent roll.

Consider a 10-unit building in Los Angeles — post-1978 construction, AB 1482 covered — completing a $120,000 soft-story retrofit. Without the pass-through, the retrofit is a $120,000 capital expense that improves the building's compliance status and eliminates the liability costs of non-compliance — a compelling return, as we've analyzed elsewhere, but a return driven by liability elimination rather than income generation.

With the AB 1482 pass-through, the owner can implement a rent increase on each of the 10 units based on the capital improvement — up to 10% of current rent per unit, subject to the overall 15% cap. On 10 units averaging $2,000 per month in rent, a 5% capital improvement pass-through increase of $100 per unit per month generates $1,000 per month in additional gross revenue — $12,000 per year. The $120,000 retrofit investment produces a 10% income return through the pass-through, in addition to the liability elimination value.

On an RSO-covered building with the same parameters, the LAHD-approved pass-through surcharge produces a similar income recovery — temporary in duration but structurally the same in its effect on the investment return.

This is the calculation that converts a capital improvement from a pure expense into a capital investment with a measurable income return. It is the calculation that most multifamily owners in Los Angeles are not making — because they don't know the pass-through mechanism exists, or because their contractor never told them that the documentation the project produces is the evidence base for the income recovery.

Why the Firm You Hire for the Capital Improvement Determines the Pass-Through Outcome

The pass-through mechanism is only as strong as the documentation it is based on. And the documentation is only as complete as the contractor who produced it.

A soft-story retrofit completed by a firm that doesn't produce a finaled permit, stamped engineering plans, and a Certificate of Compliance is a retrofit that cannot be fully defended as a qualifying capital improvement in a pass-through application. The improvement may have been made. The structure may be genuinely better. But the evidentiary record that establishes the improvement's qualifying character — its permanence, its engineering basis, its code compliance — is incomplete.

A retrofit completed by SKS Construction produces a complete documentation package: finaled LADBS permit, stamped as-built engineering plans, special inspection reports, Certificate of Compliance, and engineer's certification letter. This package is the complete evidentiary record for a capital improvement pass-through application — under the RSO program, under AB 1482, and under any subsequent regulatory framework that governs rent adjustments based on capital improvements.

We don't just build the improvement. We build the record that makes the improvement financially recoverable.
