Rent & eviction protection

Is 1266-1268 20Th 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 before 1979
Built 1956

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 1956
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 Woo Family Trust owns this 2-unit, 1-story multi-family residential building located at 1266-1268 20th Avenue in San Francisco's Central Sunset neighborhood. Built in 1956, the property has undergone several significant renovations, with the most substantial work occurring in 2008-2009. This included a comprehensive kitchen and bathroom remodel on the second floor, modification of storage rooms on the ground level, installation of a new bathroom, and upgrades to the electrical system including a main panel upgrade from 60amp to 100amp. The building's infrastructure improvements continued with the installation of a new furnace and water heater, and plumbing updates including new electrical work for storage and bathroom areas.

More recent maintenance history includes stair repairs to the rear building completed in 2002. The property has experienced some recent issues with street cleanliness and parking violations in the surrounding area, particularly in 2024, though these are external to the building itself. Notably, there was a malfunction with an elevator reported in September 2024, though this appears to be a temporary condition that was corrected. The building's recent maintenance record shows the property has generally been kept up to reasonable standards, with most historical permits showing proper completion of work, and no major safety concerns or violations on record. The property has been subject to periodic street cleaning and environmental service calls, most of which have been promptly resolved.

Risk rating

How 1266-1268 20Th 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
87thpercentile

Out of 814 buildings in this neighborhood, 106 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
