Rent & eviction protection

Is 431 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 1915
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 1915
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 residential building at 431 20th Avenue in the Central Richmond neighborhood, owned by the Anita A Pini Revocable Trust, is a two-story flats and duplex structure built in 1915. The building's maintenance history shows some significant events, particularly in 2011 when the property received multiple building violations related to peeling exterior paint, which raised concerns about potential lead hazards. These violations, filed on May 17, 2011, were documented through complaint number 201134141 and were all successfully abated by August 31, 2011. The property has undergone some infrastructure improvements, including a water service replacement completed in 2011 and the installation of a new 40-gallon gas water heater in 2018, though the permit for this work has since expired.

In recent years, the building has not had any major building code violations or complaints directly related to the structure itself. However, there have been several 311 calls in the vicinity of the building between 2018 and 2024, primarily regarding sidewalk cleaning, hazardous materials, and parking issues. The most recent service request, filed in October 2023, was a general environmental health inquiry that was transferred to the Department of Public Health. A smoke detector activation incident was recorded, but no fire or civilian injuries were reported. The property's overall record suggests that while there have been periodic maintenance issues and environmental concerns in the surrounding area, the building's major violations have been addressed and there have been no recent significant safety or habitability concerns directly related to the structure itself.

Risk rating

How 431 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
41stpercentile

Out of 2250 buildings in this neighborhood, 1328 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
