Rent & eviction protection

Is 439-441 28Th 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 1919

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 1919
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 three-story multi-family residential building at 439-441 28th Avenue in San Francisco's Central Richmond neighborhood, owned by Albert & Eva Y Wong Trust, was constructed in 1919 and contains three units. The property has undergone several significant maintenance and infrastructure upgrades over the years, including a complete reroofing in 1990 (though this permit is now expired), rehabilitation of exterior rear stairs and railing in 1996, and most recently, the replacement of a ceramic sewage pipe from the garage to the street in January 2024.

The building has experienced various inspection and maintenance issues throughout its history. A notable cluster of violations was documented in December 2002 relating to fire safety, egress obstructions, plumbing/electrical systems, and security requirements, though all were abated by February 2003. More recent concerns include a water damage and mold complaint filed in July 2022, and a fire alarm system violation issued in January 2018 that was subsequently resolved. The property has been the subject of routine housing inspections in 2000, 2012, and 2022, all of which have been marked as not active. Recent external issues documented through 311 calls include a collapsed sidewalk (January 2024) and parking violations, though these are primarily municipal rather than building-specific concerns.

Risk rating

How 439-441 28Th 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
12thpercentile

Out of 2250 buildings in this neighborhood, 1980 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
