Rent & eviction protection

Is 1339 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.

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 1339 20th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Sunset neighborhood. Built in 1924 and classified as a Flats & Duplex structure, the building has undergone several maintenance and improvement projects over the years. Most notably, in 2016, a $12,500 foam roof overlay was completed for both 1339 and 1341 20th Avenue, representing a significant roof maintenance upgrade. The building experienced a furnace change-out in early 2015, though records indicate this permit eventually expired.

The property has a documented history of maintenance issues and resident complaints, particularly regarding ventilation and weatherproofing. In July 2001, multiple violations were recorded regarding weatherproofing and siding repairs on the north side of the property, as well as exhaust fan termination issues; however, these violations were abated by September 2001. More recently, in February 2016, there was a complaint about mold in a back room of the house, though this complaint is listed as not active. The building's mechanical systems have required attention, including the aforementioned furnace replacement and roof work.

Risk rating

How 1339 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
42ndpercentile

Out of 814 buildings in this neighborhood, 472 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
