Rent & eviction protection

Is 141 Prospect Ave rent-controlled?

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 1982
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

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 141 Prospect Ave in Bernal Heights, owned by Sarah Aldrette, was constructed in 1982 as a two-story flats/duplex structure. The property has undergone several significant renovations over the past two decades, including a $15,500 front siding and trims replacement with hardi-plank in 2014, a bathroom remodel with new fixtures and vanity in 2002, and a wall heater replacement in 2011. Multiple building code violations have been documented, most notably between 2015-2019, involving unauthorized construction of rear decks, with the most recent complaint filed in October 2019 citing dangerous construction practices and possible setbacks violations. While these complaints are marked as "Not Active," their resolution status is unclear from the provided data. The building's maintenance history shows attention to basic upkeep, including a reroofing project in 2003 and various interior repairs in 2002.

The address has experienced recurring issues with abandoned vehicles in the vicinity, with numerous reports filed between 2013 and 2020, though all these cases were resolved as the vehicles were gone upon inspection. While these parking enforcement matters don't directly relate to the building's condition or safety, they may impact the general area around the property. It's worth noting that between 2020 and 2023, there have been no reported building complaints or major permit activity, suggesting either a stabilization of the building's condition or a lack of documentation for any subsequent work.

Risk rating

How 141 Prospect 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
26thpercentile

Out of 1276 buildings in this neighborhood, 944 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
