Initial analysis

The three-unit residential building at 570-572 22nd Avenue in the Central Richmond neighborhood, owned by Allen Ng & Sharon S Mar Rev, has maintained a consistent record of property upkeep since its construction in 1982. The most significant recent improvement was a kitchen remodel completed in 2018 in unit #572, which involved electrical and plumbing upgrades and was executed at a cost of approximately $22,446. Earlier maintenance work included reroofing projects in 2011 and 1994, and stucco repairs on the front of the building in 2008. A notable safety concern emerged in late 2023 with a collapsed sidewalk condition that required contractor intervention to address tripping hazards, though this was resolved by November 2023.

The property has experienced several municipal service calls over the past two years, primarily related to parking enforcement issues, including three documented cases of driveway blocking in 2024 that resulted in citations. There were also two reports of abandoned vehicles in August 2024, though these cases were either resolved or found to have no merit. The building faced some maintenance challenges in 2023, including a garbage overflow situation that required Recology intervention and a sidewalk defect that demanded follow-up from resident engineers. A fire complaint regarding combustible materials was filed in October 2018 but was determined to have no merit by January 2019. The property's maintenance history suggests regular upkeep, though recent years have shown increased incidents requiring municipal intervention, particularly regarding parking enforcement and sidewalk maintenance.

Risk rating

How 570-572 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, 518 are predicted to be safer.

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.

Estimated permit spend (past 7 years)

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

Construction spend, owner's portfolio

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

Neighborhood location

12-Month severity forecast

Moderate concern 15.5%
Severe concern 13.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
