Initial analysis

The property at 935-939 Fell Street is a two-story, three-unit multi-family residential building constructed in 1900 in the Hayes Valley neighborhood, currently owned by James B. Lewis. The building has undergone several significant improvements in recent years, including window replacements and upgrades, with the most recent work completed in 2021 involving the installation of six visible front windows with wooden double-hung sashes ($21,267) and a prior major retrofit in 2014 replacing thirteen windows and adding hardi siding to the back of the house ($30,000). The building's infrastructure has been maintained and upgraded over time, with a garage constructed under the building in 2006 ($135,000), reroofing work in 2008 ($8,000), and various plumbing improvements including the installation of a fireplace insert and gas line modifications in 2018.

The property has had two notable routine housing inspections, one in 2000 and another in 2008, with the latter revealing multiple safety and maintenance issues that were promptly addressed within a month, including concerns about dryer vents, general maintenance, security features, and fire safety equipment. Three fire code violations have been recorded: two in 2007 and 2008 relating to alarm systems and combustible materials (both corrected), and one in 2020 concerning alarm system maintenance (which was also addressed). Recent activity in the vicinity has primarily consisted of parking-related issues, with multiple citations issued in 2023-2024 for vehicles blocking driveways, though no major building or safety concerns have been reported in recent years. The building's maintenance history suggests regular upkeep, with no recurring issues or violations, and recent improvements focusing on preserving the building's historical features while upgrading its overall condition.

Risk rating

How 935-939 Fell 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.
