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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 1040 buildings in this neighborhood, 946 are predicted to be safer.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
