Initial analysis

The property at 1659 10th Avenue in the Inner Sunset is a two-unit, two-story multi-family residential building constructed in 1946, currently owned by the Angela Chii-feng Wu Revocable Trust. The building has undergone several significant renovations and faced multiple compliance issues over its history. Most notably, in 2006, there were substantial problems with unauthorized construction, including an unauthorized addition at the rear of the property, which led to multiple Notices of Violation and required leak damage repairs costing $50,000 to the foyer and south/west sides of the building. These violations remained unresolved until June 2012. The property saw various improvements in the following years, including a complete reroofing in 2006 ($9,250) and more recently, plumbing work in October 2020 involving replacement of underground sewer pipes and house trap.

Earlier records show attempts to modify the building's layout in 2002, including converting an illegal kitchen and adding a bedroom at the ground floor. The building has also experienced some maintenance issues, with termite repairs documented in 1999 and a heating system complaint in 2000 which was resolved promptly. More recent complaints, primarily from 2019-2022, have involved routine neighborhood issues such as street cleaning, sidewalk parking violations, and waste management concerns, all of which were subsequently resolved. The most significant historical compliance issues appear to have been adequately addressed, with no active violations currently on record, though there was considerable regulatory scrutiny during the mid-2000s regarding unauthorized construction and subsequent repairs.

Risk rating

How 1659 10Th 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

Out of 1493 buildings in this neighborhood, 254 are predicted to be safer.
