Rent & eviction protection

Is 4506-4508 Cabrillo 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 1924

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 property at 4506-4508 Cabrillo Street is a two-unit, two-story multi-family residential building constructed in 1924 in San Francisco's Outer Richmond neighborhood, currently owned by Wong Freeman. The building has experienced several significant maintenance and renovation events over the past two decades, with the most concerning recent incident occurring in early 2023 when improper exterior paint removal work led to complaints about volatile organic compound (VOC) fumes infiltrating tenant spaces and uncontained lead paint dust affecting the garage area. This work reportedly started without proper notification and safety measures in late January 2023. Other notable construction work includes a 2012 structural improvement project involving beam and post replacement at the ground floor ($6,500), kitchen renovations in 2006 ($7,000), and dry rot repairs to the front bay in 2003 ($800). A furnace replacement was completed in 2009, although this permit has since expired.

The property has generated multiple complaints and service requests in 2023, primarily related to construction work conditions, including one incident involving temporary restroom facilities for workers. Historical maintenance records show regular upkeep, with active attention to structural and cosmetic issues over the years. The building's recent permit history shows one streetspace permit from 2018, while several permits from earlier years have either completed or expired. The property has also experienced recurring issues with exterior cleanliness, as evidenced by multiple street cleaning service requests between 2021 and 2024, though these are generally routine municipal service matters rather than direct building concerns.

Risk rating

How 4506-4508 Cabrillo 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
10thpercentile
