Initial analysis

The three-unit multi-family residential building at 47-51 Collingwood St, owned by Mullins Living Trust, is a three-story flats and duplex structure built in 1904 in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant renovations in recent years, most notably a comprehensive 2022 renovation of one unit costing $40,000 that included electrical rewiring, bathroom modernization, kitchen cabinet replacement, and installation of a tankless water heater, followed by plans in 2024 to remove a pantry from the kitchen. Other notable improvements include the 2016 replacement of nine rear windows with new vinyl double-hung windows, and plumbing upgrades including a new house trap and pipe section installed in 2014.

The building's maintenance history shows attention to safety concerns, with multiple housing inspections in 2002 and 2013 identifying various fire safety and building code issues, including problems with fire proofing, stair repairs, and fire extinguisher servicing. These violations appear to have been addressed, as they are listed as "Not Active" in the records. Infrastructure improvements include electrical system upgrades, with a new subpanel and complete rewiring of one apartment, and multiple plumbing upgrades including a recent wall heater replacement in April 2024. While there have been several 311 calls regarding the property, most relate to external issues like sidewalk cleaning and debris removal, with only one instance of graffiti in 2022. The building's fire safety systems were activated once due to a malfunctioning alarm system, with no civilian injuries reported.

Risk rating

How 47-51 Collingwood 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 1278 buildings in this neighborhood, 511 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Building age

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

Director's hearing rate, owner's portfolio

Per-building rate of director's hearings across the owner's portfolio.

12-Month severity forecast
No violation 78.8%
Moderate concern 9.2%
Severe concern 12.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
