Initial analysis

The two-story, six-unit multi-family residential building at 143 28th Street in Noe Valley, owned by Martinovich 2000 Family Trust, was constructed in 1951 and has undergone several significant safety improvements in recent years. Most notably, the building completed a mandatory soft-story retrofit in 2015 (cost: $50,000) and an upgrade to its fire alarm system in 2021 (cost: $15,000) to comply with San Francisco fire code requirements. The property experienced multiple building code violations in late 2022 related to fire safety, including issues with combustible storage, plumbing compliance, and smoke/carbon monoxide detection systems, though these violations were all abated by April 2023. Additional recent maintenance work includes the replacement of a wall heater in 2021.

The building's historical permit record shows various improvements over the decades, including garage door replacement (2012), window upgrades (1996), roofing work (1994), and aluminum window installation (1987). The property has been subject to routine housing inspections, with several citations for fire safety and plumbing issues in 2022-2023, though these were resolved. Recent tenant mobility activity includes a buyout at the neighboring property (119 28th Street) in May 2024 for $7,000. The building's location has experienced recurring parking-related issues, as evidenced by multiple reports of blocked driveways and sidewalk parking between 2019 and 2025, though these are external to the building's conditions. A notable sewer incident occurred in 2013 involving a backup that was subsequently addressed.

Risk rating

How 143 28Th 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.
