Rent & eviction protection

Is 2631-2635 23Rd 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

The 11-unit, three-story building at 2631-2635 23rd Street, constructed in 1926 in San Francisco's Inner Mission neighborhood, is currently facing significant regulatory and compliance challenges. Most notably, the building has an active violation related to failure to comply with the mandatory soft-story retrofit program, which was identified in September 2017, with associated penalties including monthly monitoring fees and an earthquake warning placard. Recent building complaints from 2026 indicate three active concerns: the building is currently vacant with boarded windows, there are issues with an illegally installed awning, and expired permits related to structural problems. A major area of contention involves the alleged conversion of residential garage spaces into warehouse space by the business occupying part of the building, which has resulted in multiple complaints about illegal use and parking issues. The building's permit history shows a cancelled wood frame seismic retrofit permit from 2019, originally valued at $45,000, which was intended for both seismic and accessibility improvements. Over the past seven years, the property has generated 546 service requests and 11 complaints to the Department of Building Inspection, including two Notices of Violation and one Final Warning Notice, with a particular concentration of recent activity related to parking enforcement issues in 2026.

Risk rating

How 2631-2635 23Rd 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
3rdpercentile

Out of 2380 buildings in this neighborhood, 2309 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location
