Rent & eviction protection

Is 1675 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 1948
2 or more units

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 1948
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, two-story multi-family residential building at 1675 20th Avenue in San Francisco's Central Sunset neighborhood, built in 1948, has experienced several noteworthy events over the past decade. Most recently, in June 2024, there was a sewage back-up discharge incident involving a catch basin, which was promptly resolved by PUC Sewer Operations. The property has a documented history of pavement-related issues, with multiple complaints filed between 2013 and 2023, including an open pavement defect case from August 2023. The building's infrastructure maintenance has required attention to street space, with permits issued in 2014 and 2005 for street space use and scaffolding, though neither of these activities appears to have directly impacted resident safety or comfort.

The property's maintenance record shows a pattern of addressing urban infrastructure challenges, primarily focusing on pavement defects. While these issues are primarily street-related rather than building-specific, they do impact the immediate environment around the property. Additional historical incidents include a traffic engineering complaint in October 2021 that was directed to the SFMTA Livable Streets program for potential traffic calming measures, and a parking violation complaint in August 2019 involving a Honda vehicle parked on the sidewalk, though the responding officer was unable to locate the vehicle at that time. The structure itself appears to have maintained relative stability over this period, with most recorded incidents focusing on external urban infrastructure rather than building-specific concerns.

Risk rating

How 1675 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
71stpercentile

Out of 814 buildings in this neighborhood, 236 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
