Initial analysis

The two-unit residential building at 1550 Cortland Avenue in Bernal Heights, owned by Dante and Mary Giosso Family, is a single-story structure built in 1968. The building has undergone several significant maintenance and improvement projects over the years, including a $7,000 reroofing project in 2018 and an underground electrical service conversion in 2004 that upgraded the system to support two meters with 100A service. Historical records show earlier structural work from 1994, including repairs to a corner window bay and framing, though this permit has since expired.

The property has experienced various maintenance and community issues over the past few years, with the most recent incidents primarily involving external matters such as graffiti, parking violations, and abandoned vehicles. Notable recent events include a resolved case of graffiti on a pole in April 2024, illegal parking in January 2024, and a damaged property report in November 2023. The building has also experienced recurring issues with abandoned vehicles in the vicinity between 2021-2022, though these vehicles were consistently gone upon investigation. Other external matters include a noise complaint related to entertainment in April 2019 and two service requests to the Department of Public Works in 2019 and 2023, both of which were resolved.

Risk rating

How 1550 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.
