Initial analysis

The property at 4631-4633 18th Street is a 2-unit, 2-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood. Built in 1903 and currently owned by the Bolick Chan Revocable Trust, this flats/duplex-style building has undergone several significant improvements over the past decade. Most notably, in 2019-2020, both units received substantial renovations including kitchen remodels, the addition of powder rooms, and electrical upgrades with new sub-panels and related work, at a combined cost of approximately $80,000. The building has seen consistent maintenance and upgrades to its infrastructure, including HVAC improvements in 2012 with furnace and duct replacements, comprehensive insulation work in both units, and a 200-amp electrical service upgrade in 2007.

The property has experienced relatively few serious issues over its history, with the most significant concerns being environmental in nature. A 2016 complaint regarding potential lead paint violations was resolved through inspection by the Department of Building Inspection. More recently, there was a sewage backup incident reported in 2011, and multiple tree maintenance matters were addressed in 2018. The building's recent history shows regular maintenance and upgrading of systems, particularly between 2019-2020, when most major improvements were completed. The property has experienced typical urban residential issues such as street defects (resolved in 2021), temporary moving signs, and periodic tree maintenance needs, but no recurring safety or maintenance patterns of concern are evident in the records.

Risk rating

How 4631-4633 18Th St'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

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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 92.0%
Moderate concern 5.8%
Severe concern 2.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
