Initial analysis

The three-unit residential building at 672 37th Avenue in San Francisco's Outer Richmond district, currently owned by the Kwong Family Trust, was constructed in 1988 after the demolition of a single-family dwelling in 1986. The three-story flats and duplex building underwent significant renovations in 2015-2016, including the legalization of a first-floor in-law unit with two bedrooms and one bathroom, supported by corresponding electrical and plumbing permits totaling $57,000. The building has received exterior improvements, with siding replacements completed in 2016 on the east, north, and south sides using Hardie Plank siding, with each project costing $7,000.

Most concerningly, there is currently an active housing complaint filed in December 2024 regarding water intrusion, mold, and other maintenance issues in Unit 3, including reported problems with indoor smoking, cleaning standards, and electrical wiring. The building's recent history shows relatively few major issues until the current active complaint, though there have been multiple 311 calls in 2024 related to parking enforcement, shared spaces violations, and general neighborhood maintenance matters. These external incidents included reports of abandoned vehicles, sidewalk parking, amplified sound disturbances, and tree root maintenance issues, though most of these cases were either resolved or validated by responding officials. The property's permit history suggests ongoing maintenance and improvements, with the 2016 exterior siding work and the 2015-2016 conversion to a three-unit configuration being the most significant structural modifications on record.

Risk rating

How 672 37Th 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, 198 are predicted to be safer.
