Rent & eviction protection

Is 735 40Th 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 1947

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.

Just-cause eviction

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 residential building at 735 40th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1947, currently owned by Steven A Davis. The property has had minimal documented maintenance over the past several decades, with only one permitted improvement on record - a reroofing project completed in 1989. Of particular concern is an active blight complaint filed in August 2024, reporting structural defects visible from the public right-of-way and noting that the property has been vacant for several years with inadequate maintenance, including plywood boards on the ground floor and general deterioration creating an eyesore.

The building's recent history (2021-2024) shows several minor quality-of-life issues in the immediate vicinity, including two parking enforcement incidents in August 2021 related to double parking and sidewalk parking, both of which were resolved through official citations. There were also two cases of illegal postings in January 2021 that were addressed, and one report of an abandoned vehicle in July 2016 that was resolved when the vehicle was no longer present upon officer arrival. While these latter incidents reflect neighborhood concerns, they are not directly related to the building's condition or management. The most pressing current issue remains the active blight complaint regarding the property's maintenance and structural condition.

Risk rating

How 735 40Th 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
67thpercentile

Out of 1040 buildings in this neighborhood, 343 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
