Rent & eviction protection

Is 3475 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 1912
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 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 14-unit, three-story apartment building at 3475 16th Street, owned by Romel Sfapt Llc, was constructed in 1912 and has undergone significant recent modifications, most notably the addition of two ADUs in the basement level completed in 2020. The building has been through substantial safety and infrastructure upgrades, including a new fire sprinkler system installation in 2019 with 28 heads, smoke detectors, and a comprehensive fire alarm system upgrade. The property has completed its mandatory soft-story seismic retrofit under Tier 3 requirements.

Recent maintenance and safety concerns include multiple instances of water supply issues during construction in 2020, temporary blocking of egress routes, and several 311 calls regarding building systems and external maintenance. The building has experienced periodic heating and hot water system problems, with complaints in 2019 and 2021 regarding these essential services. While there have been several fire safety inspections and complaints between 2005-2021, most were determined to be without merit, though some did require corrections. The property has maintained active permits and completed various interior upgrades over the years, including plumbing and electrical improvements, bathroom renovations, and boiler system updates. Recent issues in 2024 included a sewage backup discharge from the side sewer vent, which was resolved through field work completion.

Risk rating

How 3475 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
6thpercentile

Out of 1278 buildings in this neighborhood, 1201 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
