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 1989
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 residential building at 679 20th Avenue in the Central Richmond neighborhood has undergone several significant improvements since its 1989 construction, including two substantial kitchen remodels in 2015 and 2017, each costing approximately $20,000-$22,000 and involving comprehensive upgrades to electrical systems and appliances. However, the property has faced some maintenance challenges, particularly regarding an abandoned skateboard ramp structure that generated multiple complaints in 2017, with one complaint citing it as a dilapidated and dangerous eyesore that had become a breeding ground for pests. This unauthorized structure was reportedly left in disrepair for several months, though the complaint status is listed as "Not Active."

The building's recent history shows relatively routine maintenance and service requests, with the most pressing recent issues being multiple complaints about garbage receptacle management in October 2024, though these were resolved with no evidence of ongoing violation noted during inspection. The property has experienced recurring parking-related issues in the surrounding area, with multiple citations issued for driveway blocking between 2019-2021, though these are external to the building itself. The property's permit history shows proper documentation of major alterations, including foundation work and basement modifications completed in the mid-1980s, and all recent improvements have been properly permitted and completed according to records.

Risk rating

How 679 20Th 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
78thpercentile

Out of 2250 buildings in this neighborhood, 495 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
