Initial analysis

The three-unit, three-story multi-family residential building at 1834-1838 15th Street in Mission Dolores, owned by William H. and Sandra L. Hedden, has a mixed record since its 1911 construction. The most significant incidents occurred in mid-2014, when multiple building violations were documented regarding dangerous conditions with the windows, including complaints about falling pieces of window frames and glazing. These violations, which temporarily designated the property as a nuisance under Section 1001-d of the SFHC, were addressed and abated within three days (July 25-28, 2014), following inspections and necessary repairs.

More recently, the property has generated numerous 311 calls throughout 2024, primarily related to garbage and debris on the street, with recurring reports of mattresses, furniture, and other waste being left on the sidewalk. Several calls also involved reports of needles and other debris that were either not found or resolved upon inspection. The building has experienced multiple false alarm incidents recorded by the fire department, all categorized as unintentional alarm system activations or malfunctioning smoke detectors, though none resulted in any injuries or actual fires. While these issues indicate ongoing maintenance and neighborhood cleanliness challenges around the property, it's important to note that the window safety concerns from 2014 appear to have been properly addressed and resolved.

Risk rating

How 1834-1838 15Th 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.
