Initial analysis

The two-story multi-family residential building at 3718-3720 Mission Street in Bernal Heights, constructed in 1990 and owned by Masons Legacy LLC, consists of three units plus commercial space. The property has a documented history of maintenance and habitability issues, with the most significant complaint occurring in July 1997, when multiple deficiencies were reported including a malfunctioning kitchen, broken appliances, cracked flooring, old carpeting, broken windows, mildew in several rooms, a malfunctioning garage door, inadequate lighting, and pest problems. While this complaint was officially abated in August 1997, it represents a period of significant tenant distress.

More recently, from 2020 through 2024, the property has experienced multiple infrastructure and maintenance challenges in the immediate vicinity, though none appear to involve the building directly. These external issues include recurring flooding problems on the street (November 2022 and April 2023), hazardous materials concerns (July 2021), graffiti (December 2020), and various sanitation matters including garbage, debris, and waste incidents (most recently in December 2024). The building's documented history suggests occasional maintenance challenges, particularly regarding exterior cleanliness and infrastructure issues on the street, though there are no recent complaints on record directly related to the building's habitability or maintenance conditions since the 1997 complaint.

Risk rating

How 3718-3720 Mission 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.
