Initial analysis

The two-unit residential building at 1500 15th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1938, currently owned by Lew Loren. The building's documented history shows various maintenance and safety concerns over the years, with the most significant being a set of fire complaints between 2009 and 2021, including issues with combustible materials (2009), alarm systems (2015), and an uncategorized complaint in 2021, though all were resolved with "No Merit" or "Condition Corrected" status. Historical building maintenance records show a repair project from 1987 involving work on the base rear wall, porch, and window sashes, though this permit has since expired.

In recent months (2024), the property has experienced numerous urban challenges primarily related to parking issues, with multiple complaints about vehicles blocking driveways and parking on sidewalks, some resulting in citations. There has also been one report of an abandoned vehicle and another case involving debris that required Recology's intervention, all of which have been resolved. From an environmental maintenance perspective, there was a positive development in August 2024 when Urban Trails cleared vegetation from the stair corridor, though there's currently an open complaint regarding a pavement defect that remains unresolved. The building's basic structure and systems appear generally to have maintained compliance with safety requirements, given that the majority of historical fire complaints were found to have no merit, with only one requiring correction.

Risk rating

How 1500 15Th Ave'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
73th percentile

Out of 1493 buildings in this neighborhood, 403 are predicted to be safer.
