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 1987
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 two-unit multi-family residential building at 631 25th Avenue in the Central Richmond neighborhood, owned by the Chow Pamela Living Trust, has undergone several significant modifications since its construction in 1987. The most recent major work is an issued permit for re-roofing with a cost of $20,000, scheduled for 2024, which continues the pattern of maintenance shown by a previous roofing project in 2006 that cost $4,500. The building's interior has seen various renovations, including a 1995 bathroom relocation and kitchen removal conversion to storage, as well as treatment for dry rot at the shower in 1994. Initial construction challenges were addressed in 1986 with changes to the north side footing and the demolition of the previous structure. A notable incident occurred in October 1995 when a complaint was filed regarding an illegal unit with kitchen and bathroom facilities behind the garage, though this issue was promptly abated within days.

In terms of recent property management and maintenance, there have been multiple cases of sidewalk-related issues near the building, primarily involving illegal parking and garbage concerns. Between 2020 and 2024, there were several documented instances of driveway blocking, with the most recent parking enforcement action occurring in June 2024. Street cleaning and garbage issues have been reported and resolved in various instances throughout this period, including the most recent cases in June 2024 for garbage and debris. Two instances of graffiti were reported and addressed in early 2023. While these external maintenance issues have been consistently resolved through appropriate channels, they do suggest ongoing challenges with the immediate surroundings of the property, particularly concerning parking and waste management.

Risk rating

How 631 25Th 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
75thpercentile

Out of 2250 buildings in this neighborhood, 562 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
