Rent & eviction protection

Is 350-352 23Rd Ave 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 1924

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 1924
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-unit residential building at 350-352 23rd Avenue, located in San Francisco's Central Richmond neighborhood, is a two-story flats and duplex structure built in 1924, currently owned by Donun Chan & Lily T Chan Lv. The property has undergone several infrastructure improvements over the years, including street space and sidewalk permits in 2014 and 2010 respectively, though a 2002 sidewalk permit and a 1995 reroofing permit are now expired. A significant cluster of building violations was documented in late 2007, primarily during a routine apartment housing inspection, which included issues with stair tread deterioration, combustible storage, exterior door self-closing devices, gas meter instructions, and fire extinguisher maintenance; all these violations were resolved by January 24, 2008. An earlier routine inspection was conducted in 2000 with no noted violations.

Recent activity around the property has been primarily related to parking enforcement, with multiple citations issued between May and August 2023 for driveway blocking violations, with at least four resulting in citations. Other recent incidents include a March 2022 report of human or animal waste on the street/sidewalk and a January 2022 Christmas tree removal request, both of which were resolved. The building's permit history shows regular maintenance and compliance efforts, including a 1984 project to bring the building into code compliance as required by dahi. While the property has experienced various maintenance issues in the past, particularly in 2007, there have been no recorded building violations since 2008, indicating improved maintenance of the property, though the recent pattern of vehicle parking violations suggests ongoing challenges with driveway access management.

Risk rating

How 350-352 23Rd Ave'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
30thpercentile

Out of 2250 buildings in this neighborhood, 1575 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
