Rent & eviction protection

Is 4075 California St rent-controlled?

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 1988
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-unit multi-family residential building at 4075 California Street, located in San Francisco's Inner Richmond neighborhood, was constructed in 1988 and is currently owned by the Diana Leong Family Trust. The property has undergone at least one significant renovation, with building permit records showing a $25,000 kitchen and bathroom remodel in unit #3 completed in 2002. The building experienced several safety-related issues in April 2003, when multiple violations were documented regarding fire safety concerns, including egress obstructions in the garage area, emergency lighting system problems, and smoke detector requirements. These violations were all addressed and abated by May 14, 2003. The building has undergone regular housing inspections, including a routine inspection by Housing Inspection Services in 2016, though no significant violations were noted in the most recent records.

Recent activity around the building has primarily involved street-related issues, with multiple 311 calls in the past two years regarding parking violations, including driveway blocking incidents in 2023, and reports of cars parking on sidewalks. There have also been some maintenance and public space concerns, such as illegal postings in 2022 and instances of graffiti in 2023. The only recorded fire incident was a false alarm or call, and notably, there have been no documented civilian injuries related to fires at this address. The property appears to have maintained compliance with safety regulations since the 2003 violations were resolved, with no recent building code violations on record.

Risk rating

How 4075 California 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
81stpercentile

Out of 1723 buildings in this neighborhood, 327 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
