Initial analysis

The two-unit residential building at 477-479 Collingwood Street, owned by Garrett Tyler Goff, has a documented history of maintenance primarily focused on addressing dry rot issues. Most recently, in 2019, repairs were completed on the front elevation, including dry rot remediation and window reinstallation at a cost of $6,000. A more extensive repair project was undertaken in 2018 at the rear of the building, involving stucco removal, framing and sheathing repairs, and door/window replacements, costing $25,000. The building, constructed in 1951 and classified as a two-story flats/duplex structure, is currently undergoing significant electrical system upgrades, with permits issued in late 2024 for solar panel installation and load center replacements. There have been multiple instances of dry rot repairs and window replacements documented between 2006-2019, suggesting ongoing moisture management challenges.

The property has experienced several maintenance and infrastructure issues more recently, including multiple reports of sidewalk parking violations in 2022, tree damage cases in 2021, and sidewalk defects identified in 2021. Planning records show a controversial proposal to legalize a third dwelling unit in the basement without parking, though the current status was marked as "Closed - Approved". A significant tenant buyout of $42,500 was executed in May 2024, involving one tenant. The electrical improvements currently underway include the installation of 23 roof-mounted solar PV modules and battery storage systems, representing a transition towards renewable energy. The building has a notable history of addressing moisture-related issues, as evidenced by the pattern of dry rot repairs and window replacements over the years.

Risk rating

How 477-479 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
84th percentile

Out of 1278 buildings in this neighborhood, 204 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.

Building size

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

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 78.6%
Moderate concern 11.0%
Severe concern 10.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
