Initial analysis

The 6-unit, 3-story apartment building at 250 Connecticut Street in Potrero Hill, owned by the Mary Kay Hartley Family Trust, was constructed in 1964 and has undergone several significant safety upgrades in recent years. Most notably, the building completed its mandatory Tier 3 soft-story seismic retrofit in 2016, which included the addition of new shear walls and footings, though there were some compliance issues that required attention. The property has also seen substantial fire safety improvements, including a voluntary fire alarm system replacement in 2022 that cost $26,400 and included updates to meet current San Francisco Fire Code requirements. Historical improvements include window upgrades in 1997, reroofing in 1995, and exterior siding work in 2003.

The building has experienced multiple safety-related inspections and violations over its history, including several fire safety concerns in 2007 that were resolved by 2008, and a 2020 complaint regarding incomplete soft-story retrofit work that was abated in 2022. The property has maintained good compliance with seismic retrofit requirements since then, as evidenced by the issuance of the Certificate of Final Completion. Recent activity (2023-2024) has primarily involved parking enforcement issues, with multiple reports of vehicles blocking driveways, though these are not directly related to building safety or habitability. The building has experienced three fire-related incidents since records were kept, though none resulted in civilian injuries or significant damage, including one cooking fire, a system malfunction, and a detector activation. A sidewalk defect was reported in 2020 and remains open as of 2019, though this pertains to public infrastructure rather than the building itself.

Risk rating

How 250 Connecticut 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
57th percentile

Out of 726 buildings in this neighborhood, 312 are predicted to be safer.
