Initial analysis

The property at 1056 Potrero Avenue is a three-story mixed-use building constructed in 1907, currently undergoing significant redevelopment under owner Macs Development LLC. The building's recent history is marked by substantial renovation attempts, beginning in 2016 with a major project that aimed to convert the existing structure into a five-apartment building with new bike parking, exterior improvements, and sprinkler systems. This initial project has evolved through several permits, with the most recent approved plans proposing the creation of 3 dwelling units and 6 ADUs within the existing building envelope, increasing the total unit count to 9. A voluntary seismic upgrade was also undertaken in 2020 to address soft-story concerns.

The property has experienced multiple compliance issues and construction challenges over recent years. Between 2016 and 2019, several Notices of Violation were issued, including concerns about weatherproofing, abandoned building status, egress obstructions, and sanitation issues, all of which were eventually abated. More recent complaints from 2022-2024 have raised serious concerns about building conditions, including reports of water intrusion, fire safety issues, structural problems, and abandoned construction status. The building has also faced multiple fire code violations related to storage and exit pathways in 2018, though these were processed as duplicate complaints. As of December 2024, there are active complaints regarding blight and an unregistered abandoned vacant building status. The extensive permit history includes significant infrastructure work, such as plumbing upgrades for multiple units, electrical improvements, and seismic retrofitting, though some permits have expired without completion.

Risk rating

How 1056 Potrero 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.
