Rent & eviction protection

Is 1239-1241 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.

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 1925
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 1239-1241 23rd Avenue in the Central Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1925, currently owned by Rhetc Lp. The building has undergone several significant improvements over its history, with the most recent major maintenance activity being a re-roofing project in 2002 costing $5,600. Earlier renovations include a completed second-floor interior remodel in 1999, and additional work in 1988 to address water damage in the stairs area. Between 1994-1999, there were attempts at kitchen remodeling and bathroom additions, though one permit from 1994 expired without completion.

The property has experienced recurring issues with tree maintenance, particularly in 2024, with two open cases regarding sidewalk damage from tree roots. There have also been multiple incidents of driveway blocking reported between 2022 and 2024, with at least one citation issued. Seasonal cleaning issues were noted in early 2024 with two cases related to Christmas tree disposal, both of which were resolved. The most recent parking enforcement case was resolved in October 2023, involving a White Tesla. These records suggest ongoing concerns with parking management in the area, though this is not an internal building issue. The building's maintenance history shows regular upkeep, with no recorded safety violations or recent major structural concerns.

Risk rating

How 1239-1241 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
47thpercentile

Out of 814 buildings in this neighborhood, 431 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
