Rent & eviction protection

Is 1215 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.

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

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 12-unit, 3-story multi-family residential building at 1215 Bay Street in the Marina, owned by Johnson L & Diana W Chiao T, was constructed in 1923 and has undergone significant recent improvements. Between 2020-2021, five units (5, 6, 9, 10, and 11) received comprehensive kitchen and bathroom remodels, including new appliances, fixtures, and electrical work, with project costs ranging from $13,000 to $36,000. The building underwent major maintenance in 2020, including reroofing ($77,500) and the installation of washer/dryer facilities with associated plumbing work. Of particular note, the building experienced fire damage in 2015 affecting multiple units (3, 7, 11) and common areas, requiring repairs and prompting the replacement of fire-damaged windows. More recently, in 2023, fire safety inspections identified issues with extinguishers and alarm systems, though these were promptly corrected. The building has a Tier 3 soft-story status indicating that seismic retrofit work has been completed. Historical violations primarily relate to heating system issues, egress obstruction, and alarm system maintenance, but these have all been resolved. The property's maintenance record shows regular updates to individual units and infrastructure, though there was one instance of unauthorized smoking reported in 2017 and some concerns about random noise in 2015.

Risk rating

How 1215 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
4thpercentile

Out of 988 buildings in this neighborhood, 948 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.
