Initial analysis

The property at 473-475 Fair Oaks Street in Noe Valley is a two-unit, two-story multi-family residential building constructed in 1908, currently owned by William D. and Rose Nat Grimes. The building underwent significant renovations in 2012, including the addition of a roof deck, elevator, and substantial interior updates such as kitchen renovations, bathroom conversions, and foundation repairs, with a total improvement cost exceeding $140,000. These improvements were accompanied by comprehensive electrical upgrades, plumbing work including copper pipe replacements, and the installation of a 3.45 kW solar system in 2021-2022.

The building's history includes notable concerns from 2009, when multiple violations were recorded related to building maintenance, including issues with weatherproofing, damaged ceilings, stairs, and lead paint hazards, though these were officially abated by April 2011. A concerning complaint was filed in May 2020 alleging an illegal unit merger/demolition, with claims that the duplex's separate entrances had been combined and was being marketed as a single-family home. Since then, there have been various municipal service calls in recent years, primarily related to street cleanliness, parking issues, and a tree root problem affecting the sidewalk, with one building inspection request currently listed as open since June 2024.

Risk rating

How 473-475 Fair Oaks St'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.
