Initial analysis

The three-unit residential building at 35-39 Prosper Street in the Eureka Valley/Dolores Heights neighborhood, owned by the Liu Revocable Trust, has undergone several significant renovations and experienced consistent maintenance attention since its construction in 1900. The most recent major work occurred in 2021, involving bathroom remodeling and dry rot repairs costing $14,900. Prior improvements include a substantial ground floor renovation in 2013 ($90,000) that encompassed kitchen and bathroom remodeling, foundation work, and structural strengthening, along with associated plumbing and electrical upgrades. A notable plumbing complaint regarding sewage backflow into a shower was filed in September 2021, though this issue was marked as not active.

Historical records from 2002 show multiple housing code violations related to stairs, garbage disposal, and fire safety, all of which were abated by August 2002. The building's maintenance history reveals attention to critical infrastructure, including attempts to upgrade rear stairways in 2011 (though these permits expired) and previous plumbing work in 2013. Recent 311 calls from 2023-2024 primarily concern street cleaning issues, including reports of garbage and debris, though these are more related to external conditions rather than building-specific problems. The property has undergone regular inspections and permitted improvements, demonstrating ongoing maintenance and compliance efforts by the ownership.

Risk rating

How 35-39 Prosper 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
