Initial analysis

The three-unit, three-story multi-family residential building at 23-27 Collingwood Street in the Eureka Valley/Dolores Heights neighborhood was constructed in 1908 and is currently owned by Collingwood Properties LLC. The property has undergone several significant renovations and maintenance projects over the years, with the most recent major work being the replacement of a wall heater in 2021. Historical improvements include a substantial $45,000 renovation in 2003 updating kitchen appliances, cabinets, and bathroom fixtures, and a major $22,000 project in 1994 to rebuild the rear stair and porch while adding storage and laundry facilities in the basement. The building has experienced two notable fire safety incidents, both of which were false alarms, and has had no recorded civilian injuries related to fires.

The property has a history of compliance issues that were resolved, including a 2002 violation regarding exterior door security and garbage receptacle placement, which was abated within three months. Routine housing inspections were conducted in 2000 and 2011, with no persistent violations noted. Recent activity around the building has mostly consisted of external urban challenges, including multiple 311 calls in late 2024 regarding graffiti, garbage, and other street maintenance issues, most of which were resolved by city services. Planning records show a project to demolish and rebuild the rear stair and back porch was approved, indicating ongoing attention to building maintenance and upgrades. The property has maintained three residential units throughout its history, consistent with its original configuration.

Risk rating

How 23-27 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, 728 are predicted to be safer.

Neighborhood (ZIP code)
