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 1993
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 4428 California Street, owned by the Rita Tong Revocable Trust, was constructed in 1993 following the demolition of a previous retail store in 1992. The property, located in the Lake-Presidio neighborhood, features three residential units and includes ground-floor commercial space. Recent developments include an active permit from April 2024 for the creation of two commercial units on the ground floor, with the owner-designating one as 4428B California Street. Historical improvements to the property include a roofing project completed in 2010 valued at $5,000.

The building's recent service-related history shows a pattern of street cleaning and maintenance needs in the immediate vicinity, particularly in 2023-2024, with eight documented cases including garbage and debris removal, illegal postings, and general cleaning requests. Notable recent incidents include three separate cases of garbage and debris requiring attention in late 2024, and multiple instances of illegal postings in late 2023. External environmental management issues appear to be the most significant recent concern, though these generally pertain to street-level conditions rather than building-specific matters. The property underwent substantial commercial space modifications in 1992, with an initial construction cost of $300,000 for the three-story structure that combined residential and retail uses.

Risk rating

How 4428 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
54thpercentile

Out of 660 buildings in this neighborhood, 304 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
