Initial analysis

The two-unit residential building at 476-478 Pennsylvania Avenue in Potrero Hill, owned by Precision Pennsylvania South LLC, has undergone significant renovations and improvements since 2021. The most recent major works, all initiated in 2023-2024, include comprehensive exterior updates with $35,000 approved for combined stucco and Hardie siding application, garage door replacement, and security improvements. The building has seen substantial infrastructure upgrades, including a complete reroofing ($9,500) in February 2024, installation of new drainage and water lines for multiple bathrooms and kitchens, and modernization of electrical systems with new metering equipment including a 200-amp main split and additional 100-amp meter sockets. Noteworthy interior improvements include soundproofing installations on common walls and ceilings (March 2024) and HVAC system upgrades with new Lennox equipment (though related permits have expired).

The property has experienced persistent sidewalk issues in recent years, with multiple reports of defects including lifted and collapsed sections between 2018-2023, though all were resolved following appropriate investigations. A significant tenant buyout occurred in November 2021, involving three tenants and totaling $181,280. The building's renovation history shows a pattern of systematic updates addressing both aesthetic and functional aspects, with recent focus on lighting (modification of skylights), soundproofing, and comprehensive infrastructure improvements. The property's maintenance record suggests active management response to both building improvements and external issues, particularly in addressing utility systems and building envelope maintenance.

Risk rating

How 476-478 Pennsylvania 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
