Rent & eviction protection

Is 407-409 Pennsylvania 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 1978

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 Sandoval Family Trust owns this two-unit, two-story multi-family residential building located at 407-409 Pennsylvania Avenue in Potrero Hill, which was constructed in 1978. The property underwent significant improvements in 2016-2017 to address requirements from physical inspection report #CC-8138, including the installation of two 220V 50-amp subpanels and a new hot water heater, as well as completion of sewer/housetrap replacement work. A notable windows project from 2012 involved removing and replacing 14 front windows with new fiberglass units, though this permit ultimately expired.

The building has experienced recurring issues with area maintenance and parking enforcement in recent months. Between October 2024 and January 2025, there were multiple reports of garbage and debris, including several instances involving mattresses and other waste, which were subsequently resolved. The property area has also seen frequent parking violations, with at least seven enforcement actions taken, including citations for sidewalk parking and other illegal parking incidents, though some of these cases were unable to be validated or resulted in vehicles being gone upon officer arrival. The building's permit history suggests a recent focus on maintaining basic infrastructure compliance, with all related permits from the 2016-2017 period having been completed, including electrical, plumbing, and general building work.

Risk rating

How 407-409 Pennsylvania 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
85thpercentile

Out of 726 buildings in this neighborhood, 109 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
