Initial analysis

The 4-unit, 2-story multi-family residential building at 786-792 21st Avenue in the Central Richmond neighborhood was constructed in 1921 and is currently owned by the Gallaher Non Exempt Trust. The property has undergone significant renovations and improvements over the past 15 years, with the most recent work completed in 2023 involving electrical updates including the removal of knob and tube wiring at two ceiling light locations, installation of new receptacles, and rewiring of closet lighting. Major improvements in 2021 included an upgrade to the electrical subpanel, bathroom renovations, and plumbing work for a new bathroom and closet. The building has received several substantial upgrades between 2008 and 2021, including a new roof deck (approved, 2021), various unit remodeling projects, and infrastructure improvements such as water heater replacements and seismic safety upgrades for furnaces and ducting.

The property has experienced several violations and maintenance issues, particularly between 2008-2009, including problems with improperly installed furnaces and water heaters, which were subsequently addressed. There were also multiple complaints regarding various maintenance issues in 2009, including electrical problems, window repairs, smoke detection, and rodent concerns, all of which were resolved. Historical records show the building has undergone significant electrical and plumbing updates, and most recent work suggests ongoing maintenance and modernization efforts. The roof deck was approved with specific conditions regarding privacy screens, and there is no record of recent planning code violations or complaints. While there have been several 311 calls about general cleaning and maintenance issues in the vicinity of the property, these are typical for urban locations and do not indicate any specific building deficiencies.

Risk rating

How 786-792 21St 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.
