Rent & eviction protection

Is 1200 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 1927

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.

Built 1927
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 two-unit residential building at 1200 23rd Ave in San Francisco's Central Sunset neighborhood was constructed in 1927 and is currently owned by H & K Associates. The most significant recent events occurred in May 2024, when the property faced multiple violations related to unauthorized construction work. These included both stair repairs and roofing work, with complaints filed on May 10 and 13 regarding unsafe conditions and work being performed without proper permits. The violations were promptly addressed, with the necessary permits for roof repairs totaling $12,000 being issued in May 2024 to rectify the situation.

The building's recent history has also seen various maintenance and neighborhood issues, with the most notable being the repair of unsafe stairs (with associated violation) and roofing work (both resolved by June 2024). The property has been the subject of multiple 311 calls throughout 2024, including reports of graffiti, illegal parking, trash dumping, and noise complaints. While many of these issues were resolved through proper channels, they reflect ongoing maintenance and environmental challenges in the surrounding area. The building's permit and violation history suggests a period of attention to structural maintenance requirements, though these were primarily addressed through proper channels once violations were issued. The property had no recorded building violations or significant complaints prior to 2024, indicating that most structural issues appear to have emerged recently.

Risk rating

How 1200 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
23rdpercentile
