Initial analysis

The three-unit, three-story multi-family residential building at 173-177 29th Street in Noe Valley, owned by the Mary M Rousseau Revocable Trust, was constructed in 1908 and has undergone several significant maintenance and renovation projects over the years. Most recently, in 2020, visible mold and extensive water damage were reported in the bathroom and other areas of the first floor. A 2019 complaint highlighted concerning HVAC issues, specifically improper return air ducting that allowed unconditioned garage air to enter the apartment, while both years also had reports of water-related problems. The building has a history of ventilation and roof maintenance work, including reroofing in 2010 and various roof fan noise complaints. Several significant renovations were completed in the early 2000s, including window replacements, exterior siding work, and a notable violation regarding unauthorized vinyl siding installation that led to abatement proceedings.

The property has also experienced recurring sanitation issues, with multiple violations regarding standing water conditions, though these were ultimately abated. Earlier building history includes interior demolition and kitchen remodeling work completed in 1984, and a 1986 project to bring the building into code compliance. More recent external concerns have been documented through 311 calls, primarily relating to street parking issues around the property, though these are not directly related to building conditions. The building's documented permit history shows regular maintenance and improvements, though the recent pattern of water-related issues and mold concerns may indicate ongoing challenges with moisture management in the structure.

Risk rating

How 173-177 29Th St'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.
