Rent & eviction protection

Is 3221 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.

Built 1938

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.

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 two-unit, two-story multi-family residential building at 3221 16th Street in Mission Dolores, owned by Louie/Cheung Fmy T, was constructed in 1938 and has undergone several significant maintenance and upgrade projects over the years. Most notably, in 2019 the electrical system received a substantial upgrade with the installation of new equipment and a 200-amp service, responding to PG&E requirements. The building's maintenance history includes reroofing work completed in 2010 at a cost of $7,200. A series of fire safety incidents have been recorded, though none resulted in injuries or significant damage - these include a cooking fire contained to a container, a carbon monoxide detector activation with no CO present, and an incident of arcing/shorted electrical equipment.

Recent infrastructure issues have emerged in 2024, particularly regarding sewer vent covers, with multiple reports of missing side sewer vent covers between August 26-27. The property has experienced several municipal service issues in late 2024, including parking enforcement requests, a color curb complaint, and encampment-related concerns, though most of these cases were either unable to be located or resolved by authorities. The building's immediate vicinity has faced some waste management challenges, with multiple reports of garbage and debris issues in January 2025, including overflowing city garbage cans. While these recent environmental concerns may affect resident experience, it's worth noting that similar issues appear to be affecting the broader neighborhood rather than being unique to this property.

Risk rating

How 3221 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
