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 1982
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 three-story multi-family residential building at 331 18th Avenue in the Central Richmond district, owned by Lee Toy & May S Kwong Revoc, has undergone several significant renovations and repairs since its construction in 1982. Most notably, in 2021, the building experienced water-related issues requiring repairs to multiple bathrooms, with work totaling approximately $100,000 and involving plumbing and electrical upgrades. The building's exterior has seen substantial maintenance work, including a complete bathroom remodeling in Unit A ($12,500) in 2021, re-roofing completed in early 2024 ($12,000), and several siding repairs between 2010-2018 to address water damage and leaks. A potentially concerning incident occurred in 2009 regarding inadequate hot water supply and safety hazards with the water heater, though this was promptly addressed within two weeks. A noise complaint was filed in 2020 related to construction work, which was officially addressed by the Building Inspection Division.

The property has been subject to multiple parking enforcement calls, particularly regarding sidewalk parking violations, with several citations issued in 2019-2022. There were historical maintenance issues in the late 1990s, including reports of water stains, ceiling cracks, and window problems, though these appear to have been resolved. While the building has required regular maintenance and experienced periodic water-related issues, the recent completion of significant bathroom and roofing upgrades, along with prompt responses to safety concerns, suggest active management of the property. Recent parking enforcement actions indicate ongoing issues with unauthorized parking in the vicinity of the building, though these are not directly related to building management.

Risk rating

How 331 18Th Ave'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
94thpercentile

Out of 2250 buildings in this neighborhood, 135 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
