Initial analysis

The three-unit multi-family residential building at 260 Ocean Avenue in Mission Terrace is a single-story structure built in 1933, currently owned by David & Maureen F S Costell. The property has experienced several significant events over the past two decades, with the most pressing issues occurring in 2012 when a housing complaint was filed regarding safety concerns including window functionality, egress requirements, and smoke/carbon detector deficiencies, though these were eventually noted as abated. In 2004, the building was subject to multiple violations related to unauthorized construction work in the garage area, including improper sheetrock installation and unauthorized lighting modifications, which were resolved by July 2004. This period also saw electrical work completed to correct violation notices.

The building's maintenance history shows some attention to infrastructure, with permitted work including a $12,500 reroofing project in 2015 and electrical improvements in 2006 for PG&E underground conversion. More recent activity has been mostly routine, with several parking-related complaints filed in 2023 and 2024, though these are external to the building itself. Fire department records show no significant incidents of concern, with primarily routine alarm system activations and no reported civilian injuries. The property has maintained compliance with most basic requirements, as evidenced by the closure of various complaints and violations, though the frequency of parking enforcement issues in recent months suggests an ongoing challenge with access and parking requirements in the immediate vicinity.

Risk rating

How 260 Ocean 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.
