Initial analysis

Located in San Francisco's Inner Richmond district, 682 9th Avenue is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Castleton Dillon. The property has undergone several significant renovations over the past two decades, with the most recent major work occurring in 2022, including a complete kitchen remodel ($29,000) that upgraded electrical and plumbing systems to current codes. Prior improvements include a substantial 2015 renovation that updated both bathroom and kitchen facilities across the units, featuring new cabinets, fixtures, and appliances, along with the installation of high-efficiency furnaces ($55,000). Earlier maintenance work included the replacement of 33 windows in 2004 (from aluminum to vinyl) and historical updates to the roof and rear stairs in the 1990s.

The building's maintenance record shows regular upkeep, though there have been some concerning incidents. In 2022, there were construction-related complaints filed regarding unauthorized work, after-hours construction, and noise issues, though these complaints are currently listed as not active. The property has experienced two notable fire safety incidents in May 2021 involving sprinkler/standpipe systems and alarm systems, both of which were resolved with conditions corrected by June 2021. Other historical issues include a 2018 electrical non-hazard complaint, and various parking and public space concerns around the property perimeter, though these do not directly reflect on the building's condition. Two 311 calls from 2020 regarding trees damaging property and a defaced sign were resolved, and a 2019 building inspection complaint was closed with resolution noted.

Risk rating

How 682 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
93th percentile

Out of 1723 buildings in this neighborhood, 121 are predicted to be safer.

Model explanation

What's driving this score

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building size

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

Building age
