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 2007
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 four-story, three-unit building at 320 Alemany Blvd in Bernal Heights, owned by 320 Alemany LLC, has experienced significant regulatory challenges since its construction in 2007. Most notably, in late 2022, a city inspection revealed multiple serious violations, including unauthorized unit modifications resulting in the conversion from three to six units, with unauthorized additions of fireplaces, kitchen conversions, and interior reconfigurations across multiple floors (units 1A, 2, 3A, 3B, 4A, and 4B). The building also faced violations related to fire safety, with concerns about an incomplete sprinkler system installation, missing emergency escape openings, and various fire code breaches including obstructed exit stairs and improperly secured roof access. While the owner attempted to address some issues through building permits, including a completed voluntary fire escape retrofit in late 2023, other significant problems persist. These include active plumbing violations and a pending final warning notice regarding unauthorized construction work. The building's exterior and structural elements have come under scrutiny as well, with requirements for an inspection of weather-exposed wood and metal structures including decks, balconies, and fire escapes. The property's documented history includes 7 service requests and 3 complaints processed through the Department of Building Inspection (DBI) system in the past seven years, though the most pressing issues appear to be concentrated in the recently discovered 2022 violations.

Risk rating

How 320 Alemany Blvd'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 1276 buildings in this neighborhood, 1199 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
