Initial analysis

The multi-family residential building at 626-630 9th Avenue, located in San Francisco's Inner Richmond neighborhood, is a 3-story, 4-unit flats and duplex structure built in 1913, currently owned by John K. and Jessica Wagner. The property has undergone significant renovations and modifications in recent years, with the most recent permit filed in December 2023 for a new roof deck with access stair penthouse. Major improvements in 2022-2023 included rear stairs repairs, window waterproofing, lightwell siding replacement, and structural corrections, including the addition of plywood shearwalls to comply with a Notice of Violation. The building underwent substantial interior upgrades in 2018, including the complete remodeling of 5 bathrooms, installation of new plumbing fixtures throughout, and updates to electrical systems across multiple units.

The property has had some concerning issues previously, though all have been resolved. In 2021, a complaint investigation revealed missing shear walls and an unauthorized 40 sq. ft. addition at the rear garage, which was subsequently addressed through proper permitting and structural corrections. Earlier violations from 2002 related to fire safety and security requirements were abated within two months. The building has also experienced several tenant buyouts, with significant payments made to vacating tenants between 2016 and 2018, totaling $305,000. Recent infrastructure improvements include the installation of a hydronic mini system feeder in December 2024, bathroom remodels, and the addition of three new gas furnaces in 2018. The property has maintained compliance with building codes, with all recent permits marked as complete, and currently has no active violations or complaints on file.

Risk rating

How 626-630 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.
