Initial analysis

The property at 843-845 29th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1951 and classified as a Flats & Duplex building, it has recently experienced significant structural concerns. Most notably, in October 2022, the property was impacted by a water main break that caused a moderate hairline crack (approximately 3/8 inch wide) in the front perimeter foundation adjacent to the garage entrance. This incident resulted in additional safety concerns requiring PG&E's involvement and temporary gas shutoff. While this foundation issue was officially abated by February 2023, it required multiple Notice of Violation (NOV) notifications between October 2022 and December 2022, and the incident generated substantial code enforcement attention.

Prior to these recent events, the building's record is relatively quiet, with only one notable incident from August 1995 involving construction-related disputes regarding wood storage and a bulging fence, which was promptly resolved. The property has experienced various parking-related issues in the surrounding area between 2021 and 2025, including multiple reports of vehicles blocking driveways and parking on sidewalks, though these are primarily street management concerns rather than building-specific issues. A tree maintenance issue was reported in January 2024 and remains open as of the latest data. While the foundation concerns from 2022 appear to have been addressed, the building's most recent structural history suggests attention to maintenance of critical systems should be a priority.

Risk rating

How 843-845 29Th 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.
