How San Jose Rent Control Works

San Jose’s Apartment Rent Ordinance (ARO), codified under Chapter 17.23 of the Municipal Code, is one of the oldest rent stabilization laws in California. Enacted in 1979, the ARO caps annual rent increases at a fixed 5% per year for qualifying rental units — making it simpler and more predictable than CPI-linked caps used by other California cities.

Unlike the statewide AB 1482 formula (5% + CPI, capped at 10%), San Jose’s 5% cap does not fluctuate with inflation. Whether the Consumer Price Index rises 2% or 6%, San Jose landlords with ARO-covered units are limited to a flat 5% annual general adjustment (AGA). This predictability benefits both landlords planning long-term capital improvements and tenants budgeting for housing costs in one of the nation’s most expensive metros.

The September 7, 1979 Cutoff

The ARO applies exclusively to apartment buildings with three or more units that were built and occupied before September 7, 1979. This date was established when the ordinance was originally adopted and has remained unchanged since. According to city estimates, approximately 29% of San Jose’s rental housing stock falls under ARO coverage — roughly 42,000 units across the city.

The 1979 cutoff reflects a deliberate policy choice: properties built after the ordinance took effect were developed with full knowledge of market conditions and without the expectation of rent regulation. This approach mirrors the Costa-Hawkins Rental Housing Act (Civil Code §1954.50), which prohibits local governments from imposing rent control on housing built after February 1, 1995 — though San Jose’s cutoff predates Costa-Hawkins by 16 years.

The 3-Unit Threshold

One of the most significant distinctions of San Jose’s ARO is the three-unit minimum. Single-family homes, condominiums, townhomes, and duplexes are all excluded from ARO coverage — regardless of when they were built. This is a critical difference from cities like Los Angeles, San Francisco, and Oakland, where buildings with two or more units can trigger local rent control coverage. Many San Jose duplex owners mistakenly assume they are subject to the ARO when they are not.

Just Cause Under the Tenant Protection Ordinance

San Jose’s just cause eviction protections are administered under a separate Tenant Protection Ordinance (TPO), not the ARO itself. The TPO applies more broadly than the ARO — covering many rental units that fall outside the ARO’s scope. Under the TPO, landlords must establish one of 13 enumerated just cause reasons before terminating a tenancy. These include nonpayment of rent, breach of lease terms, nuisance, illegal activity, owner move-in, substantial rehabilitation, withdrawal from the rental market (Ellis Act), and several others.

This dual-ordinance structure means a landlord with a duplex built in 1985 is not subject to the ARO’s 5% cap but may still be required to demonstrate just cause for eviction under the TPO. Understanding which ordinance applies to your property is essential for compliance.

Petition Process for Above-5% Increases

Landlords who believe the 5% cap is insufficient to cover operating costs or capital improvements may petition the San Jose Rent Stabilization Program for an above-guideline increase. The petition process involves submitting financial documentation, attending a hearing, and demonstrating that the requested increase is necessary and justified. Common grounds include major capital improvements (roof replacement, seismic retrofitting, plumbing upgrades), significant increases in operating expenses, or fair return on investment claims. The hearing officer evaluates the petition and issues a binding decision.

Properties Exempt from San Jose’s ARO

The following property types are not subject to the Apartment Rent Ordinance’s 5% cap:

• Single-family homes — regardless of age or ownership structure
• Condominiums and townhomes — individually owned units are excluded
• Duplexes (2-unit buildings) — the ARO requires a minimum of 3 units. This is one of the most commonly misunderstood exemptions in San Jose
• Accessory dwelling units (ADUs) — secondary units on single-family lots
• Buildings constructed or first occupied on or after September 7, 1979 — the original effective date of the ARO
• Substantially rehabilitated buildings — properties that have undergone major renovation may qualify for exemption upon petition
• Government-subsidized housing — units with federal, state, or local rent restrictions already in place
• Non-profit and charitable housing — units operated by qualified non-profit organizations

Even properties exempt from the ARO may be subject to AB 1482’s statewide rent cap and the Tenant Protection Ordinance’s just cause requirements. Always verify both local and state rules for your specific property.

Petition Process for Above-5% Increases

San Jose landlords with ARO-covered properties are not permanently locked at 5%. The petition process allows landlords to request above-guideline increases when justified by documented costs.

Grounds for a Petition

• Capital improvements — major repairs or upgrades that extend the useful life of the property (roof replacement, seismic retrofit, new plumbing or electrical systems, elevator modernization)
• Increased operating expenses — significant increases in property taxes, insurance premiums, utility costs, or required maintenance expenses that exceed the 5% cap
• Fair return on investment — if the 5% cap prevents the landlord from earning a constitutionally guaranteed fair return on property investment
• Debt service — costs associated with financing necessary capital improvements

How the Process Works

1. File a petition with the San Jose Rent Stabilization Program, including supporting financial documentation
2. Tenants are notified and given an opportunity to respond to the petition
3. A hearing is scheduled before an independent hearing officer
4. Both parties present evidence at the hearing
5. The hearing officer issues a decision that is binding, specifying any approved increase amount and duration

Capital improvement increases are typically amortized over the useful life of the improvement, meaning the additional rent increase is spread across multiple years rather than applied as a single lump sum. Once the amortization period ends, the rent increase attributable to that improvement expires.
