Initial analysis

850 Burnett Avenue is a 3-story, 11-unit multi-family residential building located in the Twin Peaks neighborhood, built in 1963 and currently owned by Timothy Murphy 2008 Revocable Trust. The building has experienced several maintenance and safety issues over its history, with the most recent significant work occurring in 2019 when $8,500 was spent repairing dry rot in the front left corner stucco façade. The property has undergone various fire safety inspections and corrections over the years, with documented issues related to sprinkler/standpipe systems, exit maintenance, and alarm systems between 2011 and 2023, though all were marked as "Condition Corrected." A notable cluster of violations occurred in 2003, involving garage ventilation, door security viewers, fire escape maintenance, and gas leaks, all of which were abated by October 2003.

The building's history includes one completed reroofing project in 1990 and the installation of a new fire alarm system in 1998, though this permit is now expired. Recent routine inspections have been held in 2023, 2010, and 1997, suggesting ongoing monitoring of building conditions. There is a history of parking-related issues around the property, with multiple enforcement calls recorded in late 2024, including instances of vehicles blocking driveways and parking on sidewalks. The property recently recorded a tenant buyout for $50,000 involving one tenant at 233 Glenview Drive in July 2023, though this address appears to be separate from the Burnett Avenue property.

Risk rating

How 850 Burnett Ave'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
