Initial analysis

The property at 4524-4526 Mission Street is a two-unit, two-story mixed-use building constructed in 1904, currently owned by the Peter Whitcomb Revocable Living Trust and operating as a multi-family residential building with commercial space. The building has undergone several significant maintenance and improvement projects, including re-roofing work in 2010 costing $13,000 combined for plywood installation and re-roofing, and various plumbing upgrades in 2019 (though some permits were canceled). The structure has faced multiple fire safety concerns, with violations issued in August 2023 regarding exits, fire escapes, standpipe systems, and doors. A notable fire safety violation history from July 2018 included issues with sprinklers, extinguishers, exit maintenance, and roof access, though these were subsequently abated.

The property has experienced recurring issues with graffiti, with multiple reported incidents in recent months (2024), three of which remain open or were only partially resolved. Recent maintenance concerns include a sewage back-up discharge from a catch basin in December 2024, though inspections found no significant problems. Historical complaints include a water drainage issue affecting neighboring property (2019) and a hoarding-related complaint (2016) that was noted as repeated. The building's commercial space has undergone various modifications, including electrical work for sign installation in 2007 and permits related to a bar/restaurant use (ABC Type 47) that was approved in 2018. The property has had multiple 311 calls relating to environmental issues, including offensive conditions and debris, with the most recent cases all being resolved through city services.

Risk rating

How 4524-4526 Mission 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.
