Initial analysis

The 4-unit, 2-story multi-family residential building at 1250 17th Avenue in the Inner Sunset, owned by Calvin Wong 2017 Living Trust, has a notable history since its 1914 construction. The most recent significant issue was reported in May 2023, involving water leakage from the lobby ceiling onto the stairs, with indications of potential mold. In early 2020, the building experienced multiple maintenance challenges, including heating problems, window issues, and interior surface damage, all of which were documented in a single housing complaint and subsequently abated by March 2020. During the same period, there were concerns about unpermitted water heater installation and various plumbing maintenance needs, including flue vent installation and heater replacement, though these permits expired without recorded completion.

Earlier issues include periods of vacancy with reports of broken windows and graffiti in 2018 and 2019. The building's maintenance history shows various permit applications over the years, including a street space permit from 2016 and alteration work from 1985, as well as efforts to bring the building into code compliance in 1983. Of particular note is a documented carbon monoxide incident, though no civilian injuries were reported. The property has undergone routine inspections by Housing Inspection Services in 2001 and 2009, with most recent violations related to building maintenance being addressed promptly. In terms of parking-related incidents, there have been several 311 calls regarding sidewalk parking and driveway blocking, though these were typically resolved without direct enforcement.

Risk rating

How 1250 17Th 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.
