Rent & eviction protection

Is 2331 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 1904
2 or more units
3 units
Property type
Multi-Family Residential
Zoning

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 1904
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 three-story multi-family residential building at 2331 Folsom Street, owned by Paulina V. Espinoza, was constructed in 1904 and contains three units. The property has undergone several significant events, most notably its participation in San Francisco's mandatory Soft Story Retrofit Program, which was documented as a violation in November 2017 when the owner failed to submit the required permit application and plans for seismic retrofit work. This violation, along with associated monthly violation monitoring fees and requirements not to remove an earthquake warning placard, was ultimately abated by March 2018. The building's infrastructure maintenance includes completed reroofing work from 1989 and electrical upgrades for underground utility conversion in 2004.

Recent records show a pattern of false alarm activations from 2017 through 2021, primarily related to the building's alarm system and smoke detectors, though none resulted in actual fires or civilian injuries. The property has experienced an active 311 service record in recent months (2024-2025), with numerous calls related to street cleaning, parking enforcement, and streetlight issues, particularly focusing on problems with vehicles blocking driveways. While these external issues aren't directly related to the building's condition, they reflect the surrounding neighborhood environment. The building's fire safety systems have had multiple activation events, including a cooking fire that was confined to its container, but no serious incidents or injuries have been recorded.

Risk rating

How 2331 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
43rdpercentile

Out of 2380 buildings in this neighborhood, 1357 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood (ZIP code)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
