Initial analysis

The six-unit, three-story apartment building at 645 8th Avenue in the Inner Richmond neighborhood, managed by Soo Marital Trust, has undergone several significant safety and infrastructure improvements since its construction in 1928. Most recently, in November 2023, the building's fire alarm system received a major upgrade to comply with current fire safety codes, including the installation of low-frequency sounders in sleeping areas. Of particular note is the completion of a mandatory soft-story retrofit in 2017, which involved the installation of steel moment frames, ply shear walls, and new foundations to improve seismic safety.

The building has experienced recurring sewer-related issues, with multiple complaints and 311 calls between 2019 and 2024 regarding sewage backups and vent problems, suggesting ongoing infrastructure challenges in this area. There was a significant cluster of fire safety violations in the early 2000s, including problems with the fire escape system, central alarm system, and smoke enclosure doors, though these were all abated by March 2002. A 2014 complaint noted rodent problems near trash areas and a long-abandoned bicycle on a landing, though these issues were marked as not active. Recent maintenance records show attention to various systems, including a handrail installation in 2006 and re-roofing work in 2000, indicating ongoing building upkeep. The property is classified as Tier 3 in the city's soft-story program, with work completed and a Certificate of Final Completion issued.

Risk rating

How 645 8Th Ave'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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.
