Initial analysis

The property at 1254-1256 17th Avenue in San Francisco's Inner Sunset neighborhood is a two-story, multi-family residential building constructed in 1988, containing three units and owned by Sing Chang & Bee Choo Chin. The building's construction history reveals a transition from a previous two-family dwelling that was demolished in September 1987, followed by the completion of the current three-unit structure with an installed sprinkler system that same year. Most recently, in December 2024, there was a permit issued for the replacement of nine rear windows at a cost of $6,000, though this work prompted a noise complaint from a neighboring property that was filed and abated within the same timeframe.

The building's maintenance and compliance record shows three routine housing inspections conducted in 2001, 2009, and another in December 2024 related to construction activity. The property has experienced some minor issues with street parking, with multiple reports of abandoned vehicles in the vicinity between 2022-2024, though these were mostly found to have no merit or complied with parking regulations upon investigation. A street cleaning issue was reported and resolved in 2016, and there was one construction noise complaint in December 2024 that appears to have been addressed promptly. The building's permit and complaint history suggests regular maintenance and adherence to safety requirements, with the most significant recent activity being the window replacements and associated noise concerns.

Risk rating

How 1254-1256 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.
