Initial analysis

The property at 667-669 45th Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1947, currently owned by Wiseman General G. The building has undergone significant improvements over the past several years, including substantial kitchen and bathroom remodels in both units (2015 and 2017), egress stair replacement (2015), dry-rot repair at the front balcony (2017), and reroofing (2015). All these improvements were completed with proper permits and documented inspections, except for one instance in 2016 when an upper bathroom remodel was reported without a permit, though this complaint is currently listed as not active.

The building has experienced some safety-related issues, particularly in 2020-2021, when multiple fire code violations were cited, including problems with the alarm system, sprinkler service, fire extinguisher maintenance, and exit pathways, though all these violations were subsequently abated. Additional maintenance and compliance history shows attention to plumbing and electrical systems, with documented updates to fixtures and systems during the kitchen and bathroom remodels. Recent external incidents near the property have included multiple reports of sidewalk parking violations (May 2024) and occasional graffiti (2019), though these are not directly related to building conditions. The most recent building-related activity includes an environmental health request in September 2024, though the nature and outcome of this request are not specified in the records. The property's permit history suggests ongoing investment in maintenance and improvements, with the most recent significant work being done in 2017.

Risk rating

How 667-669 45Th 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.
