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 1995
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

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 six-story, 19-unit multi-family residential building at 1608-1610 Polk Street, constructed in 1995 and currently owned by 1688 Sacramento Street LLC, has experienced a series of notable events, particularly in its recent history. Most concerning is the recent fire violation issued in December 2023 regarding sleeping area requirements, which remains open as of October 2023. The building has also faced multiple fire safety issues in 2023, including blocked exits and extinguisher concerns in November 2023, though these conditions were corrected. Previous violations include an alarm system issue in December 2021 and combustible materials concern in October 2018, indicating ongoing fire safety maintenance challenges. The building was involved in a significant 2015 incident when electrical work was performed without proper permits during a restaurant remodel, though this violation was subsequently abated.

The property's maintenance history shows various improvement projects, including a $36,000 reroofing in 2014, installation of a T-Mobile facility in 2010, and several commercial space renovations in 2015 involving plumbing and electrical work. Recent activity includes a 2024 permit to verify sound levels in sleeping areas, though the 2020 plumbing permit for new house trap work has expired. The building has experienced recurring issues with its commercial spaces, as evidenced by multiple vacant storefront complaints in 2019 and 2020. Historical records (1996) indicate past water seepage issues in the garage area, and there have been several fire alarm activations and elevator rescues recorded, though none resulted in injuries. The building's location has generated multiple recent 311 calls (as of late 2024) relating to street cleaning, illegal parking, and maintenance issues, suggesting ongoing exterior maintenance challenges around the property.

Risk rating

How 1608-1610 Polk 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
23rdpercentile

Out of 1125 buildings in this neighborhood, 866 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
