Rent & eviction protection

Is 642-644 11Th Ave 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 1915

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 1915
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 property at 642-644 11th Ave in the Inner Richmond is a two-story, multi-family residential building constructed in 1915, containing three units and currently owned by the Daniel C & Alice Wai Rvc Trust. The building has experienced several significant events, with the most recent being plumbing work completed in March 2023 involving modifications to the front water meter installation. The building's history shows two instances of fire-related events in 1988-1989, requiring repairs but no structural changes. A notable set of violations occurred in 2017 during a routine safety inspection, highlighting various safety and security issues including the need for carbon monoxide alarms, fire extinguishers, and the removal of egress obstructions; all these violations were abated by April 2017. The building underwent joist repairs at the rear in 2010, and has had various window and kitchen cabinet modifications over the years.

Recent activity around the property has been dominated by parking-related issues, with multiple 311 calls between 2023-2024 regarding sidewalk parking and driveway blocking, suggesting ongoing challenges with parking enforcement in the area. Two false fire incidents were recorded with no civilian injuries reported. The building's inspection history shows regular oversight by Housing Inspection Services, with annual routine inspections between 2002-2017 indicating active monitoring of building conditions. While the property has experienced some maintenance issues over the years, particularly noted in the 2017 violations, records show that these issues have generally been addressed promptly once identified.

Risk rating

How 642-644 11Th Ave'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
32ndpercentile

Out of 1723 buildings in this neighborhood, 1172 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
