Initial analysis

The two-unit residential building at 237-239 Prospect Avenue in Bernal Heights is a two-story flats and duplex structure built in 1925, currently owned by Christopher J. Reilly. The building's maintenance history shows several significant repairs over the past decades, including reroofing projects in 1990 and 2005 (the latter costing $5,000), window replacements in 1990, and dry rot repair at the front corner in 1995. While these historical maintenance records indicate regular upkeep, there are no documented major structural or systems upgrades in recent years.

The property has experienced several infrastructure and maintenance issues in 2024, particularly in the second half of the year, with multiple street lighting problems (three incidents between November and December), a sewage backup issue in July, and various cleaning needs including graffiti removal and garbage management. Most of these issues were promptly addressed and resolved by the respective city departments, including PUC - Sewer Operations and Street and Environmental Services. The building's immediate surroundings have faced recurring maintenance challenges, particularly with street cleanliness and lighting, though these appear to be primarily municipal infrastructure issues rather than building-specific problems. The most recent service request dated December 2024 was related to a billing inquiry with the Public Utilities Commission, which was also resolved through customer communication.

Risk rating

How 237-239 Prospect 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
