Initial analysis

The property at 431 Balboa Street is a two-story mixed-use building constructed in 1991, containing three residential units (as permitted) above ground-floor retail space. Recent significant activity includes an active complaint from 2018 regarding unauthorized dwelling units, where inspectors noted multiple life safety concerns such as unapproved wiring, plumbing, lack of smoke detectors, and improper egress arrangements. The ground floor features a commercial space that has experienced vacancy issues, with violations filed in 2021 citing non-compliance with the Vacant Commercial Storefront Ordinance. The building underwent restaurant improvements in 2008, including the conversion of a retail space to a sushi bistro bar with related electrical and plumbing work, installation of ADA-compliant bathrooms, and kitchen fire suppression system upgrades. In 2017, AT&T completed a $250,000 rooftop installation of antennas and equipment. Multiple building violations were recorded in 2014 related to fire safety, emergency exits, and hallway obstructions, though these were abated in 2022. The property has experienced various maintenance issues recently, with 311 calls in 2024 reporting sewage backups, debris, and garbage concerns, as well as a recent noise complaint.

Risk rating

How 431 Balboa 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.
