Initial analysis

The two-story multi-family residential building at 1090 Hampshire Street in San Francisco's Inner Mission neighborhood is a 4-unit apartment complex constructed in 1916, currently owned by Zigoris Fmly Tr. The property has undergone several significant modifications and faced various regulatory challenges over its history. Most notably, there is an ongoing permit application from 2021 (still in filed status) seeking to legalize an unauthorized fifth unit on the ground floor, along with necessary code updates and fire sprinkler installation. In 2003, the building underwent substantial remediation following a comprehensive inspection that revealed multiple safety issues, including problems with fire proofing, smoke detectors, stairs, electrical systems, and security features, though these violations were all abated by December 29, 2003. Other improvements to the building include a reroofing project completed in 2014 (cost: $7,200) and exterior renovations involving vinyl siding and aluminum flashing completed in 2000 (cost: $19,000).

Recent activity at the property has primarily involved external maintenance and local neighborhood issues, with multiple 311 calls in 2024 related to garbage, debris, parking violations, and a tree root issue. Of particular note is an open tree maintenance case from October 2023 regarding lifted sidewalk tree roots. The building has also undergone routine health and safety inspections in 2011, which were found to be not active, indicating no current violations or concerns at that time. The property's history includes one complaint regarding an illegal unit in the garage filed in 2000, which was resolved within approximately seven months. The most recent planning record indicates an active status for the 2021 permit application regarding the fifth unit legalization, with David Whitfield Architects listed as the developer.

Risk rating

How 1090 Hampshire 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
