Initial analysis

The Fong Family Trust #1 owns this 7-unit, 3-story multi-family residential building located at 1090 Jackson Street in Nob Hill, built in 1912. The property has undergone several significant upgrades in recent years, particularly regarding fire safety systems, with the most recent improvement completed in April 2023 costing $10,900 to upgrade the fire alarm system to comply with San Francisco Fire Code requirements. This building has a documented history of moisture-related issues, particularly in the early 2000s, when several violations were recorded in 2002 related to water damage, mold, and plumbing problems, though these were abated by November 20, 2002. More recent maintenance includes a reroofing project completed in 2020 costing $9,000, and various electrical and plumbing upgrades associated with unit remodeling.

The most recent complaint filed in September 2024 regarding rooftop access and plants blocking the passageway was resolved by October 11, 2024. The building has experienced multiple fire alarm system malfunction incidents, though no injuries were reported in these instances. There is a pattern of parking enforcement issues in the vicinity, with numerous citations issued between August and December 2024. While the building has had periodic maintenance and upgrades over the years, including various unit remodels and repairs, the recurring fire alarm system malfunctions and the recent rooftop access concerns are notable points in the building's history. Regular inspections have been conducted, with the last routine inspection recorded in 2016.

Risk rating

How 1090 Jackson 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.
