Initial analysis

247 Collins Street is a three-unit, two-story multi-family residential building located in the Lone Mountain neighborhood. The property was constructed in 1991 following the demolition of a single-family dwelling in 1987, and is currently owned by Collins-star LLC. The most recent significant improvement to the building occurred in 2021, when Unit #3 underwent a comprehensive renovation including kitchen and bathroom remodeling, electrical rewiring, and fixture upgrades at a cost of $36,750. Prior to this, there was an unsuccessful attempt in 2016 to legalize an in-law unit on the first floor, which was ultimately cancelled.

The building's history includes a number of compliance issues that appear to have been resolved. In 2003, multiple fire safety violations were documented, including concerns about fire extinguishers, emergency exits, and smoke detectors, though all were satisfactorily abated by February 2004. More recently, in early 2021, there were two complaints regarding unpermitted work in Unit #3, specifically related to electrical and general remodeling work, but these complaints are now listed as not active. Among the building's amenities, it is fully sprinkled, as noted in the 2016 permit for the now-cancelled in-law unit legalization. The property has been subject to regular municipal services calls, primarily related to street cleaning and abandoned vehicles, with no significant safety or maintenance concerns documented in recent years.

Risk rating

How 247 Collins 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
