Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1900
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The property at 274-276 Oak Street in Hayes Valley is a multi-family residential building constructed in 1900, currently owned by Raul and Denise Arriaza. The building experienced a significant fire incident on August 2, 2023, which resulted in exterior damage to the west side and roof level, along with smoke and water damage throughout the building, rendering it unsafe and uninhabitable. This incident triggered multiple building violations, including an active Notice of Violation (NOV) issued on August 1, 2023, and a final warning letter on October 10, 2023. In response to the fire damage and required repairs, the property is currently undergoing extensive renovations, with multiple permits issued in January 2024 for full unit remodeling, including kitchen and bathroom renovations, electrical upgrades, and plumbing fixture replacements. A roofing project with a cost of $25,000 was completed in November 2023.

Recent history shows the property has faced various urban challenges typical of the area, as evidenced by multiple 311 calls in 2024-2025, including reports of encampments, sidewalk blockages due to construction equipment, and exterior maintenance concerns. There was also a fire-related violation noted in May 2023 regarding combustible materials, though this was quickly resolved. The building's ongoing renovation work, as reflected in multiple permits and substantial investment, suggests active management of the property's recovery from the fire damage. The extensive scope of the current renovations includes comprehensive electrical system updates, new fixtures throughout, and compliance with engineering requirements for fire damage repairs, indicating a systematic approach to bringing the building back to habitable standards while addressing safety and modernization needs.

Risk rating

How 274-276 Oak St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
