Rent & eviction protection

Is 2639-2645 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.

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 1907
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 property at 2639-2645 24th Street in San Francisco's Inner Mission neighborhood is a three-story mixed-use building constructed in 1907, currently owned by Antonio & Rita Castellucci, containing three residential units and ground-floor commercial space. The building has a documented history of maintenance and compliance issues, with particular concern over lead paint hazards. Most recently, in late 2021, the building received multiple citations for weatherproofing and lead paint violations, with an upcoming director's hearing scheduled for February 2024. The property has experienced several significant repair events, including responses to minor fire damage in 2014 affecting the second floor's rear wall, and multiple siding and window repairs. Electrical upgrades were completed in 2009, installing additional outlets throughout the building. Recent complaints from 2024 point to ongoing lead paint and blight issues, and there are currently active concerns regarding a vacant storefront and unpermitted water heater installation from 2023.

The building's documented repair history shows attention to various maintenance needs over the years, including roofing work in 1997, subfloor replacement in 2000, and accessibility improvements in 2003. A cluster of 311 calls in early 2025 has emerged regarding garbage issues and street maintenance near the property, though these are external to the building itself. The commercial space has experienced several changes and challenges, including concerns about unpermitted use changes and sign installations, as evidenced by multiple planning records and complaints. The building's history includes several violations related to security, plumbing, and smoke detection systems, though most of these earlier complaints from 2006 appear to have been resolved. While many past issues have been addressed through proper permits and repairs, the most pressing current concerns relate to the building's exterior condition and lead paint hazards, which appear to be ongoing areas requiring attention.

Risk rating

How 2639-2645 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
1stpercentile

Out of 2380 buildings in this neighborhood, 2356 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
