Initial analysis

The two-story multi-family residential building at 660-664 8th Avenue in San Francisco's Inner Richmond neighborhood was constructed in 1923 and contains 4 units. The building has undergone several significant improvements over the years, including a complete reroofing in 2011 costing $6,270, installation of new electrical sub-panels in 2010, and the conversion of an in-law kitchen to a laundry unit in 2005. A notable renovation in 2002 involved merging a ground floor studio with an upstairs unit to eliminate an illegal unit, and a street space permit was issued in 2014.

The property has undergone three routine housing inspections (2017, 2010, and 2002) by Housing Inspection Services, with the most recent inspection in March 2017 resulting in multiple violations that were abated by April 2017. These violations included issues with fire safety equipment, gas utility requirements, and the need for a carbon monoxide detector. The building's maintenance history shows attention to both structural and safety systems, with electrical upgrades and roofing work performed in recent years. More recently, in late 2023, there was a reported infestation issue, as documented in a Department of Public Health complaint. The building has also experienced recurring issues with parking enforcement, particularly regarding blocked driveways and sidewalk parking, with multiple citations issued between 2019 and 2025, suggesting ongoing challenges with parking management in the vicinity.

Risk rating

How 660-664 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

Out of 1723 buildings in this neighborhood, 1241 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

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

Estimated permit spend (past 7 years)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 62.7%
Moderate concern 20.2%
Severe concern 17.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
