Rent & eviction protection

Is 4031-4033 24Th 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 1908

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 1908
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 4031-4033 24th Street property is a 3-unit, 3-story multi-family residential building located in Noe Valley, constructed in 1908 and currently owned by Olivia Chin Tr. The building has undergone several significant maintenance and improvement projects over the years, with the most recent being a gas line repair and hydro jet sewer work completed in April 2023. A concerning active plumbing complaint was filed in March 2024 regarding an allegedly old and illegal gas water heater, which remains under investigation by the Plumbing Inspection Division. The property has experienced various infrastructure modifications, including a complete reroofing in 2001 (at a cost of $5,700), water pipe installation in 2008, and historical kitchen and bathroom improvements dating back to 1986-1994.

The building's inspection history reveals several important issues, particularly during the late 1990s, including a significant flue pipe safety concern in 1999 that was promptly addressed. More recent inspections have shown relatively routine oversight, with water intrusion complaints in 2007 (though these were quickly resolved) and a recent fire alarm system malfunction in late 2023 that was corrected within a month. While the building itself has had its share of maintenance and permit activity, there has been noticeable ongoing external activity in the vicinity, as evidenced by multiple 311 calls in 2024 primarily related to garbage, debris, and general cleaning issues on the street and sidewalk surrounding the property. The property has maintained compliance with major housing regulations, with routine inspections showing no significant code violations, though the recent gas water heater complaint will require attention.

Risk rating

How 4031-4033 24Th 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
17thpercentile

Out of 1879 buildings in this neighborhood, 1560 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
