Rent & eviction protection

Is 3370-3374 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 before 1979
Built 1904
2 or more units

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 1904
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 3370-3374 16th Street, owned by Raul & Denise Arriaza, has undergone several significant renovations and faced various maintenance challenges since its construction in 1904. Most recently, in 2023, the property underwent plumbing work including water main replacement, and corrections were made to address confusion between 3372 and 3374 16th Street in multiple permits. A substantial renovation completed in 2021 included a new master bathroom, closet, kitchen remodel, and window replacement at a cost of $52,000. Earlier improvements included a 2013 interior remodel involving kitchen and dining room relocation and installation of a tankless water heater, and 2005 repairs to address rear stair issues following a Notice of Violation.

The building has a documented history of maintenance issues that raise concerns about resident comfort and safety. Between 2011 and 2012, multiple complaints were filed regarding mold, water leaks, and inadequate heating, with one complaint detailing extensive problems including leaks, mold, and window issues throughout the building. Additional historical violations include defective sewer issues in 2002, window problems in 2009, and various concerns about rear stairs in 2005. Recent years have shown improvement in building maintenance, with no active violations since 2020. The property has experienced minimal emergency incidents, with records showing only two fire department responses for a malfunctioning smoke detector and a motor vehicle accident, neither involving building occupants. Recent 311 calls from 2022 to 2024 primarily relate to street-related issues such as graffiti, abandoned furniture, and parking concerns, rather than building-specific problems.

Risk rating

How 3370-3374 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
32ndpercentile
