Rent & eviction protection

Is 2907-2909 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

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.

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, two-unit multi-family residential building located at 2907-2909 Folsom Street in the Inner Mission was built in 1895 and is currently owned by Brenda Ng. The property has undergone several significant renovations and improvements over the past decade, with the most recent major work occurring in 2021 when the front stairs were repaired and replaced, costing $5,000. A substantial renovation project was executed in 2015-2016, involving interior improvements to the first floor including new living spaces and extensive plumbing and electrical upgrades throughout both units. This project included the installation of a condensing boiler, radiant heating, bathroom remodels, and kitchen updates, with a total cost of approximately $205,500. The property has also been proactive in addressing flooding concerns, with the installation of a backflow preventer and drainage system modifications completed in 2016 as part of a flood rise minimization project.

The building has maintained compliance with regulations, with a significant planning record showing the removal of an illegal ground floor unit in 2011, confirming the legal status of the two units. Recent maintenance work has included window replacements in 2014 and various infrastructure improvements. The property has experienced some exterior maintenance issues, as evidenced by multiple 311 calls regarding bicycle lane blockages in 2021 and earlier, though these are parking-related rather than building-specific concerns. The building's systems have been regularly updated, including a 2013 electrical upgrade with underground service conversion and installation of new fixtures and safety systems. The property is well-documented in terms of permits and inspections, with no outstanding violations or code complaints on record.

Risk rating

How 2907-2909 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
92ndpercentile

Out of 2380 buildings in this neighborhood, 190 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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