Rent & eviction protection

Is 374-376 Prospect 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 1906
2 or more units

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 1906
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 two-unit, two-story residential building at 376 Prospect Avenue in Bernal Heights, owned by Mario A & Ilonka T Quevedo, has faced multiple significant code compliance issues since 2020. The property, constructed in 1906, is currently subject to several active violations regarding unauthorized modifications and safety concerns. These include issues with exterior stairs, decks, and the presence of an unauthorized third dwelling unit. In October 2020, complaints were filed regarding deck and stair repairs at the rear and south side of the property, with allegations of reconstruction work exceeding permitted scope and completed repairs being less than 50% of the required work. Additionally, in September 2020, inspectors reported finding a third unit at the rear of the building over two floors, complete with a kitchen and bathroom, despite city records only permitting a two-unit configuration.

To address these violations, the owners obtained a building permit in October 2022 (Permit #202210184537) for various corrective actions, including relocating exterior access stairs, adding a half-bath, legalizing a newly constructed ADU (487 sq ft), removing an unauthorized second-floor kitchen and deck, and making other modifications totaling $150,000. This permit was issued in response to multiple Notices of Violation (N.O.V.) issued between 2020 and 2022, including the Final Warning Letter from August 2022. While some progress has been made through these permits, as of October 2023, several active violations remain in the system, particularly concerning stair and deck repairs and the unauthorized third unit. The building's historical records show a reroofing project was completed in 1989, and there has been recurring parking enforcement activity in the vicinity caused by vehicles blocking the sidewalk, primarily related to a Chevrolet Chevelle (license plate 2BRD829) between 2018-2021, though these issues are unrelated to the building's structural or safety concerns.

Risk rating

How 374-376 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
2ndpercentile

Out of 1276 buildings in this neighborhood, 1250 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
