Initial analysis

The property at 4150 Irving Street is a 2-unit, 2-story multi-family residential building located in San Francisco's Outer Sunset neighborhood, built in 1942 and currently owned by Juan Carlos Sarabla. The building underwent significant modifications in 2019 when the ground floor was remodeled to accommodate an accessory dwelling unit (ADU), including the installation of new windows and replacing a garage door. This period also saw various safety upgrades, including the installation of a comprehensive fire sprinkler system in 2021 (with 14 heads) and a fire alarm monitoring system in 2022. Most recently, in 2023, the building received a solar panel installation (3.8 kW system) and a new fire alarm system installation, though the latter permit was withdrawn.

The building has experienced several maintenance and safety issues over the years, with the most concerning events occurring in 2019 when multiple complaints were filed regarding electrical problems, including broken outlets and appliance issues, as well as security concerns about unit access and a potentially illegal rental unit. These complaints were addressed and abated by July 2019. There were also earlier issues in 2006 involving water leaks, mold, and various renovation projects including bathroom remodeling. The property has undergone regular maintenance, including roofing work in 2015 and window replacements in 2006. Recent records from 2022-2024 show primarily external issues such as sidewalk maintenance needs and parking violations, with no significant building complaints or violations recorded in this period.

Risk rating

How 4150 Irving 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.
