Initial analysis

The property at 471-473 28th Avenue is a 2-unit, 2-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1917, this flats/duplex structure has undergone several significant repairs and improvements over the past decades, with particular attention required for the rear stair area. A notable incident occurred in 2017 when unauthorized replacement of the rear stairs was reported, leading to a code enforcement investigation and subsequent Notice of Violation (NOV #201797371). The unauthorized work was completed by Abel C. Maldonado Construction, and to rectify the situation, a proper permit was obtained in September 2017 with a $20,000 cost to install new footings and framing, which was successfully completed by February 2018 and marked as abated.

Other maintenance work includes window replacements (2004), minor dry rot repairs (2000), and rear stair repairs (1987), demonstrating ongoing attention to the building's upkeep. A significant infrastructure upgrade was performed in December 2020 with the replacement of up to 20 feet of water service lines. Recent 311 calls primarily concern external matters such as parking violations and tree root issues, with one open case from April 2020 regarding damaging property from tree roots lifting sidewalk surfaces. The building's maintenance record shows consistent attention to structural elements, particularly regarding the rear stairs which have required multiple interventions over the years.

Risk rating

How 471-473 28Th 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.
