Rent & eviction protection

Is 3476-3480 16Th 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.

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 1912
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-unit multi-family residential building at 3476-3480 16th Street, owned by F Loy & Helen Fong Family Trust, is a 3-story flats and duplex structure built in 1912. The property has undergone several significant improvements and maintenance work over the past decades, including a 2010 window upgrade from aluminum single-pane to vinyl double-pane windows, replacement of approximately 22 rotted steps in 2010, and installation of a direct vent gas fireplace in 2016. In 2016, concerns were raised about peeling lead paint on the west wall, particularly affecting the 3rd and 4th floors, with attention drawn to potential risks for children in the vicinity. The building experienced multiple violations in 2004 related to fire safety and lighting, though these were successfully abated by October 2004.

The property's maintenance history includes various routine inspections dating back to 1995, and several improvements to safety features such as rear stair and basement motion detector lighting installation in 2004. Recent external issues documented through 311 calls primarily involve street-level concerns such as graffiti (most recently in 2021-2022), sidewalk parking violations (2023), and occasional reports of waste on the street or sidewalk (2018-2019). The most recent documented building-specific work was a street space permit issued in 2017, suggesting some form of exterior modification, though the cost was listed as $0. The property's documented history shows regular maintenance and prompt responses to violations, with no active building code or safety violations currently on record.

Risk rating

How 3476-3480 16Th 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
39thpercentile

Out of 1278 buildings in this neighborhood, 780 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
