Initial analysis

The three-story, two-family residential building at 654-656 9th Avenue in San Francisco's Inner Richmond district was completed in 1988 following the demolition of a single-family dwelling on the site in May 1987. The property, currently owned by the Mitsuo Tsumoria 1990 Trust, has undergone several significant improvements over the years, with the most recent being a complete reroofing project in November 2022 costing nearly $26,000. The building has seen substantial window upgrades, with two major replacement projects - one in 2014 replacing 10 windows with Anderson wood clad units, and a more extensive project in 2013 replacing 28 aluminum windows with new paintable wood composite units featuring grids to match the existing windows.

The property has maintained an active maintenance record, including historical improvements such as the 2002 reroofing and installation of sprinkler plans during its original construction in 1987. Several quality-of-life issues have been documented through 311 calls, including a sewer issue in November 2019, a mold and mildew complaint in October 2017, and sidewalk maintenance concerns in 2012 involving tree root damage that affected approximately 80 square feet of sidewalk. The latter issue was resolved through proper inspections and remediation. While the building has experienced typical urban maintenance and parking-related incidents, including several vehicle-related complaints and a burnt-out streetlight in the vicinity, these do not appear to directly impact the building's structural integrity or resident safety. The property's documentation shows regular upkeep and compliance with building codes, with no recorded violations or serious safety concerns.

Risk rating

How 654-656 9Th 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
85th percentile

Out of 1723 buildings in this neighborhood, 258 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.

Building size

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

Owner's portfolio size

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 82.0%
Moderate concern 11.1%
Severe concern 6.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
