Initial analysis

The 439-441 15th Avenue property is a two-unit, two-story multi-family residential building constructed in 1923 in the Central Richmond neighborhood, currently owned by the Thomas W Lim Revocable Trust. The most significant recent improvements include a comprehensive kitchen remodel completed in October 2024, involving both electrical (installation of a 60-amp subpanel with multiple circuits) and plumbing (new sink, drain lines, and gas line) work with a reported cost of $38,000. The building has undergone several notable maintenance and upgrade projects over the years, including the replacement of the main drain line and house trap in 2016, installation of a water heater pan with drain in 2015 (following a plumbing complaint), and seismic improvements in 1987 with foundation reinforcement.

The property has experienced some maintenance issues requiring attention, including a plumbing complaint in March 2015 regarding washing machine drainage overflow, which was resolved by April 2015. There have been infrastructure concerns such as a sewage backup incident in November 2022 and several street-related issues recorded through 311 calls, including garbage/debris incidents in 2024 and parking violations. The building's safety record shows two fire-related incidents: a contained cooking fire and a malfunctioning smoke detector, neither of which resulted in civilian injuries. While the property has had its share of maintenance and compliance matters over the years, recent records indicate ongoing improvements and prompt resolution of issues as they arise.

Risk rating

How 439-441 15Th 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.
