Initial analysis

The three-unit residential building at 4526 Irving Street in the Outer Sunset, owned by Susanna Shui Ying Kwong Rev, was constructed in 2004 and consists of two stories. The property has undergone several significant improvements over its lifetime, including a complete re-roofing project in July 2023 costing $37,000, installation of a fire alarm system and sprinkler system during construction in 2004 and 2003 respectively, and a plumbing upgrade in 2014 involving a 3/4" bypass assembly installation. The building's original construction in 2002-2004 included comprehensive electrical work, with the installation of multiple electrical systems including 65 lights, 38 switches, 100 receptacles, and various appliance connections.

Recently, there has been one active building complaint from February 2023 regarding construction work involving grinding operations that reportedly created sparks and noise affecting neighboring properties. There has also been a pattern of parking enforcement issues, with multiple complaints about blocked driveways recorded between September and November 2024, though many of these were invalid due to incomplete reporting information. An operational business complaint was filed regarding the charging of Bird Scooters and delivery operations from the property, though this was listed as informational in the planning records. The building has experienced one documented fire incident related to cooking, though it was contained with no civilian injuries reported.

Risk rating

How 4526 Irving 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 632 buildings in this neighborhood, 398 are predicted to be safer.
