Inner Mission, SF 94110 6520007 3 units · 3 fl · 1900

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 2840-2848 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.

Built before 1979
Built 1900
2 or more units

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.

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

This three-story, multi-family residential building located at 2840-2848 Folsom Street in San Francisco's Inner Mission neighborhood was constructed in 1900 and contains three units. The property underwent significant improvements in 2016, including a completed soft-story retrofit costing $50,000 to improve seismic stability, and substantial renovations to units 2846 and 2848 featuring kitchen updates, communication features, and accessibility improvements. The building's infrastructure has been maintained with several important updates, including a complete reroofing in 2009, heating system upgrades in 2016, and sewer repairs in 2019. The property also successfully completed a 200-amp underground electrical conversion in 2004.

The building's maintenance record shows regular upkeep, though there have been some quality-of-life issues reported in recent years. Multiple 311 calls between 2022 and 2024 have been logged regarding parking violations, including bicycle lane blockages and driveway access issues, though these are primarily external to the building itself. There was one notable incident requiring attention in 2010 regarding smoke detector placement in stairwells, which was promptly addressed within nine days. Recent complaints from 2023 include reports of graffiti and a noise complaint from late 2024, though these appear to be routine urban issues rather than major building concerns. The building's owners have demonstrated compliance with safety requirements, as evidenced by the completed soft-story retrofit and timely responses to inspection findings.

Risk rating

How 2840-2848 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
52ndpercentile

Out of 2380 buildings in this neighborhood, 1142 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Per-building complaint rate across the owner's portfolio.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.
