Initial analysis

The 6-unit, 2-story multi-family residential building at 283 20th Ave in the Central Richmond neighborhood, owned by Elaine Richards, was constructed in 1926 and has undergone several significant improvements over the past decades. Most notably, the building completed mandatory soft-story retrofit work in 2019 (Tier 3) to strengthen wood shear walls and comply with seismic safety requirements, with the work's cost amounting to $65,000. Recent maintenance includes roofing work and siding replacement in 2023, with a project value of $9,800. Unit #5 received substantial renovations in 2019, including a remodel of living spaces, window modifications, kitchen updates, and electrical system improvements with a combined cost exceeding $28,000, as well as plumbing upgrades involving water line relocation.

The building's maintenance history shows attention to critical infrastructure, with a complete sewer line and trap replacement in 2012, though there were some earlier issues that required attention. In 2003, the building faced multiple violations related to ventilation, fire safety, and alarm systems, though these were all resolved by September 2003. A 2005 complaint regarding insufficient heat was similarly addressed within one day. An annual inspection in 1995 and a routine inspection in 2009 showed normal regulatory oversight. More recently, the property experienced typical urban maintenance issues, as evidenced by 311 calls for street cleaning in 2021 and 2024, which were resolved promptly.

Risk rating

How 283 20Th 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

Out of 2250 buildings in this neighborhood, 1552 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 72.9%
Moderate concern 16.5%
Severe concern 10.6%
