Outer Richmond, SF 94121 1598035 2 units · 1 fl · 1923

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 740-742 47Th 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.

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.

Annual rent increase cap

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 740-742 47th Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, single-story multi-family residential building constructed in 1923, currently owned by Bypass Trust. The building has undergone several notable improvements over its lifetime, with the most recent significant work occurring in 2019 when one front window was replaced with a wood casement window and three back windows were upgraded to vinyl sliders. A substantial kitchen remodel was completed in 2014, including new cabinets, countertops, appliances, and associated electrical and plumbing work. Earlier improvements from 1989 included the addition of a family room and full bath on the ground floor, along with repairs to front stairs, dry rot issues, and window work.

The building has experienced several maintenance and infrastructure issues in recent years, with the most pressing being a sewage backup incident in November 2023 that required field work by the PUC Sewer Operations. Tree-related matters have been a recurring theme in the area, with multiple reports between 2021 and 2023 regarding overgrown trees, damaged trees, and sidewalk issues caused by tree roots, with the most recent complaints being logged in November 2023. The property has also faced periodic challenges with parking enforcement, as evidenced by three separate incidents in 2022-2023 where vehicles were reported blocking driveways, all of which were resolved through official intervention. While historical permits indicate various structural and aesthetic improvements, the recent sewage issue and ongoing tree maintenance concerns represent the most significant current challenges affecting the property and its surroundings.

Risk rating

How 740-742 47Th 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
9thpercentile

Out of 1040 buildings in this neighborhood, 946 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
