Initial analysis

The two-story, four-unit multi-family residential building at 506-508 Shotwell Street in the Inner Mission was constructed in 1904 and is currently owned by Frank & Delores Gagliardi L. The building has undergone several maintenance updates, most notably a complete reroofing project in 2024 valued at $16,400, and previously in 1997. In 2009, a permit was filed for the installation of two new curb cuts measuring 10'-011". The property has a history of health and safety inspections, with violations recorded in 2003 relating to the lack of handrails and missing gas meter instructional diagrams; however, these issues were promptly addressed and abated by November 25, 2003. A routine housing inspection in 2011 was also conducted and resolved.

Recent activity at the property has been primarily related to parking and street cleaning issues. Between 2022 and 2025, there have been multiple enforcement actions taken for vehicles blocking driveways and parking violations, with citations issued in several cases. The most recent building-related activity was the reroofing project completed in 2024, which represents the most significant building maintenance work in recent years. The building appears to be maintaining compliance with building codes following the resolution of past violations, with no active violations currently on record. While there have been several 311 calls regarding street cleaning and debris between 2022 and 2024, these are primarily external to the building itself and relate to public sidewalk maintenance.

Risk rating

How 506-508 Shotwell 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
