Rent & eviction protection

Is 2507-2509 San Bruno Ave 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 1907

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 2507-2509 San Bruno Avenue property is a two-unit, two-story multi-family residential building with a commercial space, located in the Portola neighborhood and constructed in 1907, currently owned by the Leung/yu Family Trust. The building has undergone several significant improvements over the past two decades, including a conversion from overhead to underground electrical service with a 200-amp system installed in 2003, sewer main repairs in 2008, a re-roofing project in early 2013, and a kitchen remodel later that same year. Of particular note is a building complaint filed in May 2023 regarding the main building being vacant, though this complaint is currently listed as not active.

In recent months (December 2024 - January 2025), the property vicinity has experienced multiple maintenance issues primarily related to street cleaning, with at least ten reports of garbage, debris, and graffiti on or near the property. The majority of these reports have been resolved through inspection and appropriate action, including one noted instance of a posted Notice of Violation for sidewalk graffiti. Historical building maintenance records show a pattern of systematic upkeep, with the most recent substantial work dating back to 2013. While the building has maintained basic safety and structural improvements through various permits, the recent cluster of street-level issues suggests ongoing challenges with property maintenance in the immediate surroundings.

Risk rating

How 2507-2509 San Bruno Ave'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
23rdpercentile

Out of 255 buildings in this neighborhood, 196 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
