Initial analysis

The two-unit residential building at 491 29th Street in Noe Valley, owned by the Elizabeth T Erhardt Living Trust, is a two-story flats and duplex structure built in 1911. The building's maintenance history reveals two significant structural repairs: in 2004, approximately 60 square feet of water-damaged wall framing was replaced at a cost of $3,500, and in 1987, dry rot was addressed in the back porch siding. These repairs suggest periodic moisture-related maintenance issues, though no similar problems have been reported in recent decades.

The property has generated several municipal service calls over the past ten years, with the most recent being a resolved parking enforcement issue in March 2024 regarding a driveway blockage. Other notable incidents include an illegal posting removal in 2019, a reported abandoned vehicle in 2018 (which was gone upon arrival of authorities), street cleaning in 2016, and a temporary moving sign request in 2015. A significant planning matter was approved in 2014 regarding a variance for coverage, usable open space, rear yard, and density. Finally, a 2014 incident involving garbage cans being left out continuously resulted in outreach and enforcement action, though this appears to have been successfully resolved.

Risk rating

How 491 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.

Neighborhood percentile
