Rent & eviction protection

Is 769-773 45Th 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 1930

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 1930
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 769-773 45th Avenue in the Outer Richmond is a 2-unit, 2-story multi-family residential building constructed in 1930, currently owned by the Sandra H Chen Trust. The building's maintenance history includes a significant foundation work in 2007, when approximately 30 feet of the north property line footing was reinforced using chemical grouting, at a cost of $10,000. A serious complaint was filed in October 2002, reporting multiple issues including a non-functioning heater, a ceiling collapse, water leakage affecting the apartment below, and concerning bathroom floor conditions, though the current status of these problems is not specified in the records.

Recent activity around the property has primarily involved parking-related enforcement, with multiple citations issued in June 2024 for sidewalk parking and driveway blockage. There have been some municipal service issues in the vicinity, with open Muni maintenance complaints regarding overhead lines from 2021-2022, and various street and sidewalk matters including a missing street cleaning sign (October 2021), a pavement defect assessment that found no current issues (May 2021), and street cleaning concerns (March 2021). The most recent documented incident was a street light repair completed in July 2020. While the building has undergone some structural work in the past, the maintenance and complaint history shows no documented recurring building-specific issues since 2002, though the age of the building suggests ongoing maintenance would be expected.

Risk rating

How 769-773 45Th 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
41stpercentile

Out of 1040 buildings in this neighborhood, 614 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
