Initial analysis

The two-unit residential building at 517-519 Paris Street in San Francisco's Excelsior neighborhood, constructed in 1917, has undergone significant recent improvements under the ownership of Gurson S Dang 1990 Trust. Most notably, in 2024, comprehensive renovations were completed to convert storage space into habitable areas, including a bedroom, office, and bathroom, along with substantial plumbing and electrical upgrades. These improvements included the installation of a tankless water heater, new bathroom fixtures, kitchen updates, and an electrical panel upgrade to 100 amps. Prior to this, in 2022, the building received additional maintenance work including door replacements, bathroom repairs, electrical updates, and kitchen preparations for future improvements.

The property has a relatively clean maintenance record, though there was an instance in October 2022 involving building code compliance issues, which were promptly addressed and marked as "Not Active." Historical records from 1999 show some plumbing and ceiling issues that were quickly resolved. The building's infrastructure has been regularly maintained, with documented improvements to electrical systems in 2004, 2005, and 2007, including service upgrades. Recent months have seen multiple parking-related incidents near the property, with several citations issued between August and December 2024 for violations including sidewalk parking and double parking, though these are external to the building's conditions and management.

Risk rating

How 517-519 Paris St'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 337 buildings in this neighborhood, 219 are predicted to be safer.
