Initial analysis

The two-unit residential building at 656-658 35th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1914, currently owned by Roy M Guinnane. The property's maintenance and improvement history shows several permitted upgrades over the years, including a kitchen remodel in 1996, a horizontal addition that expired in 1997, the installation of a half bathroom and private office in 1998, and reroofing work completed in 1991.

Recent activity at the property has primarily involved parking-related issues, with multiple complaints about driveway blocking between October 2023 and January 2025, though enforcement officers were often unable to locate the offending vehicles. There were also several instances of sidewalk parking violations in 2022 that resulted in citations. A significant regulatory matter occurred in late 2023 when the Rent Board confirmed that the property was exempt from rental fees. Additionally, there was a short-term rental compliance issue at 658 35th Avenue, where it was alleged that the owner was operating unauthorized short-term rentals through Airbnb. This complaint was investigated and ultimately abated, with instructions given to cease such activities, and the property appears to have transitioned to 30-day minimum stays thereafter.

Risk rating

How 656-658 35Th 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 1040 buildings in this neighborhood, 520 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 75.2%
Moderate concern 19.0%
Severe concern 5.8%
