Initial analysis

The three-unit, three-story multi-family residential building at 1541-1543 15th Street in the Inner Mission, owned by the Delarosa Marital Trust, was constructed in 1910 and has undergone several significant maintenance and compliance-related events over the past two decades. Most notably, in 2015-2017, the building underwent window replacement work following a violation for unpermitted vinyl window installations, with three windows being converted from vinyl to wood ($4,500) to meet code requirements. The property has experienced recurring issues with stair safety and fire safety compliance, with violations recorded in 2003 and 2008 related to wooden stairs that required repairs, and fire safety concerns including missing fire extinguishers in 2008. Historical improvements include a comprehensive interior rehabilitation in 1990 involving cabinet, flooring, and bathroom updates, along with the installation of new furnaces on every floor.

More recently, between November 2024 and January 2025, there have been multiple reports of garbage and debris issues near the property, with some cases still open as of January 2025. These concerns primarily relate to loose garbage, yard waste, and abandoned furniture. The building has a history of routine safety inspections, with records from 2003, 2006, and 2008 showing various compliance matters that were subsequently resolved. The most recent known window-related work was completed in 2017, when the building underwent modifications to comply with building codes, though previous complaints had been filed regarding unpermitted window replacements. The property has also experienced some infrastructure issues, as evidenced by a November 2024 sewer flooding incident that was resolved, and has been subject to routine maintenance inspections by housing authorities.

Risk rating

How 1541-1543 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.
