Rent & eviction protection

Is 1446-1448 Thomas 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 1910

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 1910
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 property at 1446-1448 Thomas Avenue in Bayview, owned by the Ng Family Trust, is a 2-unit, 2-story multi-family residential building constructed in 1910. The building has experienced several significant maintenance issues over the past decade, with the most pressing current concern being lead paint hazards identified in May 2023, which required work to address severely peeling and flaking paint at the exterior. Historical complaints from 2021 noted severe structural concerns regarding a storage unit, while earlier complaints from 1996-2005 documented a range of issues including inadequate heating, water leakage, damaged walls, electrical problems, and plumbing concerns. The property has undergone some infrastructure improvements, such as water heater relocations and pipe upgrades in 2009, and a gas houseline extension in 2010. Recent developments include multiple street parking enforcement calls and sidewalk-related complaints in 2024, though these are not directly related to building conditions. The property has faced recurring issues with exterior maintenance and safety, as evidenced by multiple housing inspections and violation notices over the years, with the most recent lead paint violations being addressed in November 2023.

Risk rating

How 1446-1448 Thomas 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
30thpercentile

Out of 382 buildings in this neighborhood, 267 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
