Initial analysis

The two-unit residential building at 1671-1673 12th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1948, currently owned by Eric L. Chow. The property has undergone several significant renovations over the years, including multiple bathroom remodels: in 1999, both units received bathroom updates, followed by a more extensive $13,000 renovation in 2005 of unit 1673's bathroom and the addition of a master bath, which was accompanied by electrical work including new lighting and outlets. The building's roofing was completely redone in 1991, indicating proper maintenance of essential systems.

A notable incident occurred in July 2004 when a complaint was filed regarding power loss that raised safety concerns about potential fire hazards, though this issue was resolved within a week. More recently, in March 2020, one tenant accepted a buyout for $17,368.89 at the 1671 12th Avenue address, though this is not directly related to the duplex property's current status. The most recent activity, from January 2024, was a routine street cleaning matter involving an abandoned Christmas tree, which was resolved by Recology. The building's permit and complaint history suggests regular maintenance and updating of facilities, with no recent complaints or major issues affecting resident safety or comfort.

Risk rating

How 1671-1673 12Th 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.
