Inner Mission, SF 94110 6521035 3 units · 3 fl · 1908

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 2831-2835 Folsom 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.

Annual rent increase cap

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

2831-2835 Folsom Street is a three-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, owned by the Katya Jaen Trust 2005 and constructed in 1908 as a three-story flats and duplex structure. The building has undergone several significant renovations and maintenance work over the past decades, with the most recent notable incident occurring in December 2024 involving a damaged tree on the property. In 2011, the building underwent repair work on the second and third floors, specifically addressing issues in two small laundry rooms at 2833 and 2835, while earlier improvements in 2005 included comprehensive electrical rewiring of key areas including bedrooms, kitchen, dining room, living room, and hallway, along with kitchen remodeling across all three units.

The building's history shows attention to safety concerns, particularly during a routine housing inspection in 2003 that identified multiple issues including problems with smoke detectors, emergency exits, and stairs that required repairs, though these violations were all abated by December 2003. Subsequent inspections in 2011 also occurred but were not associated with any major violations. The property has experienced recurring issues with external graffiti and tree maintenance, with multiple 311 calls between 2021 and 2024 regarding damaged trees, graffiti, and parking violations in the vicinity. While the building has undergone various repairs and improvements over the years, including laundry room repairs, deck/stair repairs, and electrical upgrades, it has also faced multiple instances of exterior maintenance challenges such as graffiti and tree-related issues, which appear to be ongoing concerns as evidenced by recent 311 calls.

Risk rating

How 2831-2835 Folsom 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
62ndpercentile

Out of 2380 buildings in this neighborhood, 904 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
