Rent & eviction protection

Is 34 Gaven 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.

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 1900
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 34 Gaven Street is a one-story, two-unit multi-family residential building located in the Portola neighborhood, constructed in 1900 and currently owned by the Rosita T Castaneda Revocable Trust. The building's permit history shows one record dating back to 1995 for a horizontal project costing $3,000, though this permit has since expired.

The most notable recent activity associated with this property involves a cluster of 311 calls for service in early January 2025, with multiple reports of garbage and debris on the street and sidewalk areas. While many of these cases have been resolved with no work needed, there are several calls still marked as open or in progress, indicating ongoing concerns with street cleanliness around the property. Additional issues noted in January 2025 include reports of graffiti on sidewalk structures. The building has no recorded fire incidents or violations in its recent history, though there was a fire alarm system maintenance violation recorded at the nearby 625 Bay Shore Boulevard address in 2019, which has since been abated.

Risk rating

How 34 Gaven 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
75thpercentile

Out of 255 buildings in this neighborhood, 64 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
