Rent & eviction protection

Is 1329-1331 Bay 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 1928

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 1928
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 residential building at 1329-1331 Bay Street in San Francisco's Marina neighborhood has undergone several significant events and improvements since its construction in 1928. The property experienced multiple maintenance challenges in 2022, including water leaks, plumbing issues, and deteriorating paint conditions, particularly during the first half of that year when violations were documented for problems with the ground-level corridor, sewage backups, and chipping paint in bedrooms. These issues culminated in a director hearing in June 2022. However, the building has since undergone substantial improvements, with completed building permits showing significant work including a voluntary seismic soft-story retrofit completed in 2022, bathroom and kitchen remodels in 2023, and window replacements on the front facade in 2024. More recent concerns include two complaints filed in June 2025 regarding address visibility issues from the street, and an open 311 service request from July 2026 concerning a collapsed sidewalk. The property has maintained an active permit history with a total construction cost of approximately $443,400 over the past seven years, and although there were multiple violations and complaints between 2022 and 2025, many of these issues have been addressed through subsequent renovations and repairs.

Risk rating

How 1329-1331 Bay 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
16thpercentile

Out of 988 buildings in this neighborhood, 830 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
