Initial analysis

The 14-unit apartment building at 480-484 6th Street, owned by the Mae S Lee Living Trust, was built in 1916 and consists of three stories. The building is currently in violation of San Francisco's mandatory Soft Story Program requirements, having been classified as Tier 4 Non-Compliant, with an active complaint filed in December 2022 citing failure to complete retrofitting. The most recent building-related issue was a mold problem in July 2024 linked to a leak, though this was abated by August 2024. In 2016, the building experienced several interrelated issues that resulted in multiple violations, including water damage, plumbing problems, and deficiencies in smoke detection systems, all of which were resolved by December 2016. The property has undergone various improvements, including a $66,700 residential retrofit in 2018 to comply with the Soft Story Program and accessibility improvements costing $16,000.

The building has a history of fire safety concerns, with recent violations issued in 2018 for sprinkler/standpipe systems and most recently in 2024 for fire escape maintenance, though both were subsequently abated. There have been multiple false fire alarm incidents and smoke detector activations recorded, though no civilian injuries have been reported in any fire incidents. The ground floor of the building continues to operate as a limited restaurant under the name "Grab N Go," which is permitted in the building's zoning classification. Recent 311 calls regarding the property mainly relate to external issues such as parking violations and street cleaning needs. The building's maintenance history includes several repair and upgrade projects, including the replacement of a water heater in 2016 and various other interior and structural improvements over the years.

Risk rating

How 480-484 6Th 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.
