Rent & eviction protection

Is 907-909 Clayton 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 1906

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 1906
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.

The property has a documented history of stair-related maintenance issues, with repairs to exterior stairs and landings occurring in 2014, 2006, and as far back as 1989. A significant cluster of building violations was recorded in 2006, including issues with stairs, security features (deadlatch locks and self-closing doors), and a fire safety concerns, all of which were addressed by March 2007. Another set of violations was documented in 2011 regarding lead paint, fire extinguisher maintenance, and gas meter instructions, which were promptly resolved within two months.

In terms of building maintenance, a roof replacement was undertaken in 2008 at a cost of $14,750, and various stair repairs have been completed over the years.

Risk rating

How 907-909 Clayton 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.

Neighborhood percentile
85thpercentile

Out of 526 buildings in this neighborhood, 79 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
