Initial analysis

The 4-unit, 2-story multi-family residential building at 791-797 21st Avenue in the Central Richmond neighborhood, owned by Helene Daigian Haroutinian, has undergone several significant renovations and faced some notable issues since its construction in 1921. Most recently, in early 2022, substantial improvements were made to units 795 and 797, including new sink and dishwasher installations, kitchen cabinet replacement, and extensive electrical rewiring with a new subpanel installation at a cost of $32,000. Prior to this, in 2021, additional electrical work was completed, including wiring updates for various living spaces. The building experienced multiple code violations in May 2003 related to plumbing, electrical systems, stairs, fire safety, and egress compliance, though all were promptly abated by July 2003. A period of garage-related concerns occurred between 2005-2006 when complaints were filed regarding unauthorized use of the garage for a painting business, leading to violations related to combustible materials and chemical storage, which were ultimately resolved by 2014. Historical records show earlier improvements including reroofing work completed in 2000 and a code compliance effort in 1985.

More recently, the property has experienced ongoing issues with garbage and debris in the vicinity, with multiple reports (at least eight) filed between August 2024 and November 2024, though these appear to be external to the building itself and primarily concern street cleaning matters. While the building has faced various maintenance and safety compliance challenges over the years, all known violations have been addressed and resolved, with no active violations on record as of now. The most recent building improvements (2022) suggest ongoing maintenance and upgrading of the property's systems and amenities, though the frequency of recent street cleaning complaints indicates some ongoing challenges with waste management in the immediate area.

Risk rating

How 791-797 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.

Neighborhood percentile

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
