Rent & eviction protection

Is 523 Campbell 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 1904

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1904
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 three-story, two-unit multi-family residential building located at 523 Campbell Avenue in Visitacion Valley has undergone several significant infrastructure improvements since its construction in 1904. Recent improvements include the installation of solar panels in 2016 (18 PV modules), a new electrical meter main panel in 2012, and major plumbing upgrades in 2014 including the replacement of the house trap and underground main sewer line. The building has also seen earlier maintenance work, including reroofing in 2012 and window replacements in 1998-1999. However, the property has a troubling history of safety concerns, particularly highlighted by multiple complaints filed in October 2018, alleging serious issues including unpermitted structural modifications, gas leaks, illegal plumbing work, and unauthorized electrical installations - some of which reportedly nearly caused a fire. A comprehensive complaint filed in August 2018 detailed hazardous living conditions, including gas leaks, electrical problems, and structural concerns. The building's maintenance history shows both proper upgrades and concerning pattern of complaints regarding unauthorized modifications.

Most recently, between October and December 2024, there have been multiple reports (nine in total) of garbage and debris issues in the vicinity of the property, primarily involving loose waste and abandoned items, though these are not directly related to building conditions. While many of these recent cases have been resolved, they do indicate ongoing challenges with waste management in the immediate area. The building's documented permit history shows regular maintenance and improvements over the years, though the frequency of improvements and repairs suggests ongoing attention to basic infrastructure needs. The property is currently owned by Anne Seeman, though historical records show previous ownership by Seeman Anne.

Risk rating

How 523 Campbell 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
24thpercentile

Out of 214 buildings in this neighborhood, 163 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
