Initial analysis

The property at 317-321 8th Avenue in San Francisco's Inner Richmond district is a two-story mixed-use building constructed in 1921, containing three residential units and ground-floor commercial space. The building has experienced recurring fire safety issues over the past several years, with multiple documented fire code violations between 2017 and 2022, including problems with alarm systems, fire extinguisher service requirements, exit sign illumination, door repairs, and kitchen hood cleaning. All of these violations have been officially abated according to records. Recent building improvements include the installation of partition walls, office fronts, hand wash stations, dental equipment, and associated plumbing and electrical work in 2012-2013.

The property has undergone various maintenance work over the years, including aluminum window installation in 1986, bathroom window replacement, and roofing work in 2003 (though this permit expired). Recent concerns around the property primarily relate to external conditions, with multiple 311 calls regarding garbage and debris, sidewalk cleaning, and general maintenance issues throughout 2022-2025. There have been two notable fire complaints in 2022, though these were resolved promptly. The property has also recorded some infrastructure issues in the immediate vicinity, with an open tree damage case from July 2024, and other external matters like graffiti and abandoned vehicle complaints that have been addressed by city services.

Risk rating

How 317-321 8Th 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.
