Portola, SF 94134 5457023 3 units · 2 fl · 1951

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 2857-2859 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 1951
2 or more units

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

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1951
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 2857-2859 San Bruno Avenue is a two-story mixed-use building constructed in 1951, containing three residential units over a ground-floor commercial space. The building has undergone several significant events over the past decade, most notably a period of code enforcement activity between 2013-2015 regarding unpermitted construction of a new room with window in a vacant store space, which was eventually addressed through completion of a permit to remove the unauthorized work. In 2011, there was a plumbing-related violation regarding water leakage from the building's rear north side, which was subsequently resolved. More recently, there have been multiple environmental health and sanitation-related issues in 2024, with several 311 calls concerning garbage and debris on the property, though these have generally been resolved promptly by city services.

The building's permit history shows various improvements and maintenance work, including an underground electrical system upgrade in 2004 and reroofing work in 1993. A significant proposed modification - the addition of a third floor residential unit - was submitted for permit in May 2024, but this application was subsequently cancelled. The property is currently under monitoring for public health and environmental concerns based on 311 calls in late 2024. Fire department records indicate two service calls with no injuries reported, one related to an unintentional smoke detector activation and the other classified as a miscellaneous service call. The building's ownership is currently held by the Lilian Choi Revocable Trust.

Risk rating

How 2857-2859 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
44thpercentile

Out of 255 buildings in this neighborhood, 143 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
