Rent & eviction protection

Is 1525 Clay St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1910
2 or more units
16 units
Property type
Multi-Family Residential
Zoning

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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.

Built 1910
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

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 four-story, 16-unit multi-family residential building at 1525 Clay Street in Nob Hill, constructed in 1910 and currently owned by 1525 Clay Street LLC, has undergone several significant safety system upgrades in 2023, including a $50,945 fire alarm system upgrade to comply with SF Fire Code requirements. This upgrade involved modernizing the fire panel, updating all existing devices for compatibility, and installing low-frequency sounders in sleeping areas to meet the required 75dB at pillow standard. The building has a documented history of water-related issues, with notable incidents in 2007 and 2015 involving bathroom ceiling leaks and water damage affecting multiple units. These historical problems were addressed, along with various interior surface violations including damaged ceilings, lead paint concerns, and security issues documented in a 2001 routine inspection.

The property has faced several fire safety concerns in recent years, with violations recorded in 2019 (fire extinguisher issue, corrected) and 2022 (sprinkler/standpipe system violation and building owner contact posting requirement, both abated). While the building has experienced minimal fire-related incidents with no civilian injuries reported, there have been multiple parking enforcement calls regarding driveway blockages and several pavement defect reports on the surrounding street. Recent exterior issues included two instances of graffiti in 2021, though these were resolved. The property's maintenance history suggests ongoing attention to safety requirements, as evidenced by the recent comprehensive fire alarm system upgrade, though the building has experienced recurring water-related maintenance issues over the years.

Risk rating

How 1525 Clay 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

Grade A–B — Low risk

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

Grade C — Moderate risk

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

Grade D–F — High risk

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