Rent & eviction protection

Is 4263 California St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1911
2 or more units

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.

Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

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, six-unit apartment building at 4263 California Street, located in San Francisco's Inner Richmond neighborhood, was constructed in 1911 and is owned by Antonio and Rita Castellucci. The property has experienced several significant maintenance and safety issues, particularly during the mid-2000s. In May 2005, multiple violations were documented related to interior surfaces, including problems with paint, damaged ceilings, and concerns about lead-based paint hazards, with these violations remaining unresolved until October 2005. Additional violations in May 2006 noted issues with window sashes and continued paint problems, including lead hazard warnings, though these were also resolved by October 2005. Two routine safety inspections were conducted in 2004 and 2016, with the 2005 inspection specifically noting mold, mildew, and some structural damage.

The building's permit history includes an expired permit from 2001 for the construction of a new 3-car garage with a deck above in the existing rear yard, valued at $50,000, and a renewal permit in 2005 for final inspection. Electrical work was completed in 2005, which also involved the neighboring property at 4293 California St. More recently, from 2024 to early 2025, there have been multiple municipal service calls recorded near the property, primarily relating to parking enforcement issues, waste removal, and graffiti, though these are external issues not directly related to the building's condition. The most recent documented routine safety inspection in 2016 did not reveal any active violations, suggesting improved maintenance standards in recent years.

Risk rating

How 4263 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
16thpercentile

Out of 1723 buildings in this neighborhood, 1447 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.
