Initial analysis

The two-story, three-unit multi-family residential building at 733-737 Spruce Street in the Lone Mountain neighborhood, owned by Chew Thli&suey Kam Wong '04, was constructed in 1980 and has undergone several significant renovations since then. In 2017, the property underwent a substantial window upgrade, installing 16 new windows and a patio door at a cost of $22,750, with 12 street-facing windows receiving fiberglass Millguard Ultra Series treatments, while others were replaced with vinyl windows featuring U-Factor .29 and SHGC .23 ratings. Prior to this, in 2016, the building received deck repairs costing $12,750, which included the removal of existing decking, protection of underlying joists, and installation of new Trex decking on less than 50% of the deck surface.

The building's inspection and complaint history shows regular oversight, with routine housing inspections conducted in 2000 and 2004, both of which were completed without any noted ongoing issues. Recent activity at the address has been minimal, with only two instances of graffiti on a nearby transit shelter in 2018, which were promptly addressed, and a 2024 report of garbage and debris that was resolved by Recology. The property's maintenance record suggests careful upkeep of major building components, with the most recent significant improvements focusing on energy efficiency and structural elements such as windows and decking.

Risk rating

How 733-737 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
68th percentile

Out of 519 buildings in this neighborhood, 166 are predicted to be safer.
