Initial analysis

The three-story multi-family residential building at 610 Cortland Avenue in Bernal Heights, owned by Douglas F Wong & Pearl W Ye, consists of 5 units and was constructed in 1960. The property underwent significant ground floor modifications between 2014-2016, including the conversion of two required residential parking spaces into a daycare facility and ATM, along with associated improvements such as a new storefront, accessible restroom, and comprehensive fire safety upgrades including a new fire control unit, voice evacuation panel, and two-hour fire-rated hallways. More recent maintenance work includes a sewer house trap replacement in 2022 and various infrastructure upgrades in 2015 such as electrical service enhancements, plumbing work, and HVAC installation.

The building's history reveals some concerning maintenance patterns, particularly in recent years. A 2018 complaint noted persistent issues with garbage overflow and maintenance in the garbage room, which was described as a potential fire hazard. There were multiple fire safety-related violations in 2001 that were subsequently abated, including issues with smoke detectors and fire enclosure doors. Recent maintenance concerns have also been documented through 311 calls, including graffiti incidents in 2023 and sewer-related issues in 2019. While the property has experienced periodic violations and maintenance issues over the years, most recent permits and work suggest ongoing investment in building systems and infrastructure, though the frequency of graffiti and sewer-related complaints indicates some persistent exterior maintenance challenges.

Risk rating

How 610 Cortland 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
