Rent & eviction protection

Is 1344-1346 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.

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.

Just-cause eviction

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

This two-unit multi-family residential building, located at 1344 20th Ave in the Central Sunset neighborhood, was built in 1922 and is owned by the Wong Family Trust. The property has undergone significant recent improvements, with comprehensive kitchen remodels completed in both the upper (1344) and lower (1346) units in March 2024, followed by a bathroom renovation in the lower unit in August 2024, including electrical upgrades and new fixtures totaling approximately $85,000. Heating and ventilation systems were also addressed with the installation of new furnaces in the garage in August 2020.

The building has a history of maintenance and safety issues that required attention, notably during a cluster of violations filed on June 19, 2020, which included problems with heating, electrical systems, security features, and mold in the bathroom. These violations, which were serious enough to result in a Final Warning Letter in September 2021 and a director hearing in December 2021, were ultimately abated by June 26, 2023. Earlier issues included a plumbing leak in June 2020 that affected the downstairs unit, kitchen drain problems in June 2019, and a sewage backup incident recorded in April 2019. Historical records show the legalization of an existing storage room in the basement in 1987, and a street space permit was issued in 2015. The most recent work on the property represents a substantial investment in upgrading the building's infrastructure and living conditions, suggesting improved maintenance standards moving forward.

Risk rating

How 1344-1346 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.
