Rent & eviction protection

Is 618-620 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 1900

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.

15+ years since occupancy
Built 1900
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 618-620 Pennsylvania Avenue is a two-unit, two-story multi-family residential building located in Potrero Hill, owned by Walter E Hughes Jr & Emily and constructed in 1900. The building has undergone significant improvements over the past decade, with major renovations occurring between 2013-2015 including comprehensive electrical upgrades, kitchen and bathroom improvements, and HVAC system replacements. In 2014-2015, the building underwent a substantial modernization project with an electrical service upgrade, new kitchen appliances, bathroom upgrades, and furnace replacement, along with related plumbing work including drain and vent modifications.

The property had a notable cluster of violations in late 2012-early 2013, with multiple housing code violations identified in September 2012 regarding inadequate heating, broken glass, fire safety equipment, security, lighting, lead paint concerns, and various interior maintenance issues. These violations were all reported as abated by January 2013, suggesting they were addressed promptly. A subsequent complaint regarding damaged doors and windows was filed in June 2013 and resolved by December 2013. More recently, from 2022 to 2023, the building has only required minimal maintenance, including the replacement of a non-street-visible rear window in December 2022. The property has experienced recurring issues with vehicles blocking the driveway, with three such incidents reported in 2023-2024, though these are unrelated to building maintenance or safety concerns.

Risk rating

How 618-620 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
60thpercentile

Out of 726 buildings in this neighborhood, 290 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Building age
