Initial analysis

The 4-unit, 2-story multi-family residential building at 234-236 18th Avenue in the Central Richmond neighborhood, built in 1912 and currently owned by the Yick Chung Wat Trust, has undergone several significant maintenance and code compliance events over the past decades. The most recent building-related work occurred in 2009 when stucco repairs were completed in response to a Housing Inspection Services complaint about peeling stucco. A major cluster of violations was documented in 2002, primarily related to fire safety and plumbing concerns, including issues with egress obstruction, combustible storage, fire proofing, drainage pipes, and water heater flues, all of which were resolved by October 2003. The building underwent routine inspections in 1996-1997, and 1988 records indicate work to bring the building into code compliance.

More recent history shows a series of parking-related incidents on or near the property, with multiple citations issued between 2019 and 2023 for vehicles blocking driveways or parking on sidewalks. Two general cleaning issues related to loose garbage were reported in 2020, and there was one incident involving a damaged tree in 2019 that required arborist attention. The building's last recorded fire incident was a public service assistance call with no civilian injuries. Throughout its history, the property has maintained compliance with necessary repairs and inspections, with all documented violations being properly addressed and abated.

Risk rating

How 234-236 18Th 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, 1778 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.

Building age

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

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 57.9%
Moderate concern 30.9%
Severe concern 11.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
