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

Annual rent increase cap

Coverage unclear. AB 1482 turns on the certificate-of-occupancy date and property type — confirm the year the building was completed.

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 595 Mariposa Street is a five-story, multi-family residential building containing 20 units, constructed in 2017 under the ownership of Soma Acquisition LLC. The building has undergone significant infrastructure upgrades since its completion, including plumbing improvements such as a new combined storm and sewer system, water pipes, and water heaters installed in 2017-2019. The building has experienced recurring issues with boiler permits, with violations filed in 2020 and most recently in March 2024 for two boilers (serial numbers 1722106283289 and 1722106283290), though these violations were abated within weeks. A notable accessibility concern was documented in June 2021 regarding the front entrance and elevator access for disabled individuals, particularly during a period when the elevator was reportedly non-functional. The building's fire safety systems have been the subject of multiple violations and complaints, including issues with alarm systems, fire sprinkler systems, and blocked exits between 2010-2024, with the most recent violations concerning the ERRCS (Emergency Responder Radio Coverage System) in 2024. Recent 311 calls from January 2025 indicate ongoing concerns with garbage management and encampments in the vicinity of the property. The building appears to have maintained compliance with most building permits, including recent ERRCS upgrades in 2021 and final inspections in 2022, though there have been multiple revisions and confirmations regarding various systems throughout its operational history.

Risk rating

How 593-599 Mariposa 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 74 buildings in this neighborhood, 70 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
