Initial analysis

The two-unit residential building at 666-668 22nd Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1981, currently owned by the May Yon Lee Ma Living Trust. The property has undergone two significant maintenance work projects during its lifetime, with the most recent being a repair to the left side siding in September 2019 due to dry rot, which included the installation of new 1"x8" hardie siding with vapor barrier & flashing at a cost of $8,000. In July 2007, the building underwent window replacement work, installing new vinyl windows of the same size that were visible from the street, at a cost of $7,200. An earlier permit from 1982 appears to have been cancelled.

The property has been subject to numerous parking enforcement issues in the surrounding area, with eight reports of abandoned vehicles between 2022 and 2025, though most of these resulted in "Gone on Arrival" outcomes when enforcement officers arrived, except for two vehicles that were towed - one in June 2024 for expired registration and another in August 2022 after 72 hours of being reported. Additionally, there was one incident in March 2023 involving a Port-A-Potty blocking the sidewalk, which was resolved after inspection when the temporary structure was removed. While these reports indicate ongoing parking challenges in the immediate vicinity, they primarily concern public street areas rather than the property itself, and none of the incidents directly relate to the building's condition or resident experience.

Risk rating

How 666-668 22Nd 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 2250 buildings in this neighborhood, 540 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.

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.

Neighborhood location

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

12-Month severity forecast
No violation 79.0%
Moderate concern 13.1%
Severe concern 7.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
