Initial analysis

The property at 1201-1207 18th Avenue in San Francisco's Inner Sunset neighborhood is a two-story, four-unit multi-family residential building constructed in 1923 and currently owned by the Chiu Family 2010 Trust. The building has experienced several significant maintenance and safety issues over the years, with the most notable cluster of problems occurring in 2011 when multiple violations were documented regarding fire safety and building maintenance, including required repairs to bedroom walls and ceilings, kitchen ceiling holes, living room ceiling cracks, and various instances of peeling paint. These violations were eventually abated by December 2015. Earlier maintenance work included repairs to rear wooden stairs and fire escape in 1998, repair of the rear wall and foundation work in 1984, and several corrections made in 1983 under Department of Building Inspection orders to bring the building into compliance with current codes.

More recent history shows ongoing challenges with parking enforcement in the immediate area, as evidenced by numerous 311 calls between 2022 and 2024 regarding vehicles blocking driveways or parking on sidewalks. There have also been recurring issues with garbage and debris on the street, with several general cleaning requests recorded in 2023-2024. While these issues pertain to the surrounding area rather than the building itself, they do indicate ongoing neighborhood management challenges. The building has undergone routine housing inspections in 2001 and 2009, and there was a complaint in 2000 regarding unauthorized professional/commercial office use in the ground floor space, which was quickly resolved. The most recent building-related activity recorded was a parking enforcement response in December 2024, though this was not directly related to the building's conditions or management.

Risk rating

How 1201-1207 18Th 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.
