Initial analysis

The 7-unit, 3-story multi-family residential building at 601 Burnett Ave in Twin Peaks, owned by Trilateral Inc, has undergone significant improvements to its life safety systems in recent years, most notably with a comprehensive fire alarm system upgrade completed in March 2023 costing nearly $35,000, which included the installation of new smoke detectors, heat detectors, pull stations, and horn/strobes. The building has a history of structural maintenance and improvements, including several deck replacements, window upgrades, and roofing work between 1992 and 2022, with the most recent deck-related improvements occurring in 2017.

The property has maintained an active maintenance schedule, addressing various building and safety requirements over the years, though it has experienced some notable issues. In 2017, there was a complaint regarding unsealed work areas and potential lead paint disturbance, and multiple violations were recorded between 2001 and 2017 related to ventilation, fire safety, and weatherproofing, all of which were subsequently abated. While the building has experienced numerous false fire alarm activations and one smoke detector activation incident (all with zero civilian injuries), these incidents generally correspond to system malfunctions rather than actual emergencies. Recent activity at the property has primarily involved routine external maintenance matters, as evidenced by multiple 311 calls for sidewalk cleaning and general maintenance in late 2023, though these are typical for the area and not indicative of any systemic issues with the building itself.

Risk rating

How 601 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
57th percentile

Out of 172 buildings in this neighborhood, 74 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 53.6%
Moderate concern 25.2%
Severe concern 21.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
