Rent & eviction protection

Is 669-671 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.

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 1908
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 669-671 Pennsylvania Avenue property in Potrero Hill is a three-story, two-unit multi-family residential building owned by the Shelan 2011 Family Trust and constructed in 1908. The building has undergone several significant maintenance and safety-related improvements over the years, most notably a sewer lateral replacement completed in 2020 and a structural retrofit of existing gravity framing in 2016. A notable building violation in 2008 resulted from unauthorized construction of new stairs and concrete piers, which was subsequently addressed through a $16,500 permit to properly remove and replace rear and side stairs. This incident also triggered a fire safety complaint regarding blocked exits, though these conditions were corrected promptly in both cases.

The property has experienced multiple maintenance issues between 2020 and 2022, including several reports of damaged trees (with multiple complaints registered in September 2021) and one instance of graffiti in April 2022, all of which were resolved. The most recent incident was a parking enforcement issue in January 2024. While the building's major structural and safety improvements have been properly documented and addressed through appropriate permits, the property has experienced occasional maintenance challenges typical of its age and type, particularly regarding exterior elements like stairs and trees. The building's permit and violation history suggests that when issues have arisen, they have generally been addressed through proper channels, though there was an initial period of unauthorized work in 2008 that required remediation.

Risk rating

How 669-671 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
55thpercentile

Out of 726 buildings in this neighborhood, 327 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
