Initial analysis

The two-unit multi-family residential building at 643 Spruce Street, owned by Fong Bayard P & Rosa A, was constructed in 1925 and features two stories. The property has undergone several window replacement projects over the past few years, most notably following a violation notice issued in September 2021 regarding unauthorized window replacements. This violation, which involved the installation of six vinyl windows on the second floor at the front of the building without the required permits, was ultimately resolved in March 2024 after the proper procedures were followed. The owners completed a permitted window replacement project in April 2022, installing new Pella architectural aluminum-clad wood windows on the street-facing facade and vinyl-framed windows on the rear side. A subsequent window replacement permit was issued in March 2024 for additional street-facing windows.

The building's history also includes a completed kitchen and bathroom remodel from 1987, and a brief housing inspection case in 1995 concerning allegations of illegal units in the basement, which was resolved within three months. More recently, there was a parking enforcement issue in February 2024 involving a Honda Accord parked on the sidewalk near the property, which was addressed by responding officers. The ongoing series of window replacements, both before and after the 2021 violation, suggests an active commitment to maintaining and upgrading the building's exterior features, though the initial unauthorized installation raised some compliance concerns with city regulations.

Risk rating

How 643-645 Spruce 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.

Neighborhood percentile

Out of 272 buildings in this neighborhood, 114 are predicted to be safer.
