Initial analysis

The two-unit residential building at 1205-1207 31st Avenue in Central Sunset, constructed in 1938, has experienced significant recent activity, particularly regarding unpermitted modifications. In November 2021, building violations were filed against both units, documenting unauthorized work including kitchen and bathroom renovations, wall removals, and various installations. These violations triggered a complex permitting process, culminating in 2022 permits (PA#202208110302, PA#202207057780) to address the issues, including the legalization of an ADU and various kitchen modifications. The property has also required several infrastructure updates, including a water line replacement in December 2024 and multiple electrical and plumbing compliance measures in 2022.

Two active building violations remain pending, with a director's hearing scheduled for February 2024, related to unpermitted modifications including exterior wall openings, kitchen work, and unauthorized gas installations. The building underwent an illegal ADU conversion process that began in 2022 and was partially rectified through subsequent permits, with an estimated cost of $128,300. Periodic maintenance records show historical work including reroofing in 1989 and recent plumbing repairs. The property's exterior surroundings have experienced various municipal service calls in late 2024, primarily related to graffiti removal, pavement issues, and a fallen tree, though these are not direct building concerns.

Risk rating

How 1205-1207 31St 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.

Neighborhood percentile
