Initial analysis

The three-unit, three-story multi-family residential building at 648-652 7th Avenue in San Francisco's Inner Richmond district, built in 1907, has undergone several significant maintenance and safety events over the past few decades. The property has experienced multiple fire code violations from 2018-2024, with the most recent occurring in September 2024 regarding test and maintenance documentation, which remains open. A routine inspection in December 2015 revealed several issues requiring attention, including structural maintenance requirements, carbon monoxide and smoke alarm concerns, fire extinguisher deficiencies, and lead paint safety violations, all of which were abated by January 2016. The building's maintenance history shows periodic attention to structural elements, including foundation repairs in 1985 and reroofing work in 1996, though some permits from the 1980s have expired.

Recent activity at the property has generated multiple 311 calls primarily related to street cleaning, parking violations, and general maintenance issues in the surrounding area throughout 2023-2024, though these are more relevant to the neighborhood than the building itself. The property has a documented pattern of fire safety violations, with specific issues noted regarding sprinkler systems, door self-closers, fire extinguisher maintenance, and alarm systems between 2018-2024. While many of these violations have been abated, the building's fire safety maintenance record suggests ongoing attention is required to maintain compliance. The building's owner, Wong Fay Y Survivors Trust, holds the property title, and the building's age and history indicate regular maintenance and compliance checks have been necessary throughout its existence.

Risk rating

How 648-652 7Th 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.

Building size

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Owner's portfolio size

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

12-Month severity forecast
No violation 65.6%
Moderate concern 17.8%
Severe concern 16.6%
