Initial analysis

The three-unit residential building at 4249-4251 18th Street, located in the Eureka Valley/Dolores Heights neighborhood, was constructed in 1900 and includes a retail component. The property has a notable history of construction and renovation activity, particularly between 2010-2012, when several significant works were completed. This period included a change of use from retail to food service in late 2010, followed by multiple permits for related improvements including sink installations, electrical upgrades, and compliance with building code requirements. The building experienced some permit violation issues in late 2010 related to unauthorized construction work, but these were resolved by April 2012 through proper permitting and inspections.

More recent history shows limited significant building modifications, with the most substantial work being a roof replacement in 1996. The property has been the subject of various street-related complaints in 2023-2024, primarily concerning illegal parking incidents near the building, though these are external to the property's structural condition. Three recent 311 calls (January, November 2024) involved street cleaning matters, but only one specifically mentioned the presence of waste, and no major building code issues have been reported in recent years. The property also has an approved planning record for Limited Restaurant use as of October 2023, allowing for restaurant operations within the existing structure.

Risk rating

How 4249-4251 18Th 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
