Initial analysis

The two-unit residential building at 1986 25th Street in Potrero Hill, owned by Antonio & Lazara Cornejo, is a two-story flats and duplex structure built in 1965. The building has undergone several improvements over the years, with the most significant recent work occurring in 2014 when approximately 1,200 square feet of plastic siding was replaced with stucco on the front and left sides at a cost of $30,000. Earlier maintenance records show tile replacement work was completed in the kitchen and bathroom areas in 1993, and there was an earlier, now-expired permit from 1987 for vinyl siding installation.

The property has experienced a pattern of parking-related issues in recent years, with multiple enforcement actions recorded between 2021 and 2024, including citations for sidewalk parking, blocked driveways, and double parking. The most recent incidents in October 2024 involved construction equipment blocking a crosswalk and a resolved parking violation. There was one building inspection complaint transferred to the Department of Building Inspection in February 2024, and a pavement defect report in February 2021. Of particular note, a fire-related complaint was filed and referred to another agency in March 2024, though no additional details are available. The building's maintenance history suggests regular upkeep, with the most substantial exterior upgrade occurring in 2014, while the ongoing parking enforcement issues indicate a continuing challenge in managing street access around the property.

Risk rating

How 1986 25Th 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.
