AI summary

The two-unit, two-story multi-family residential building at 4344 Balboa Street in the Outer Richmond, constructed in 1923, has undergone several significant maintenance and compliance events over the past two decades. Most notably, the property has experienced three routine housing inspections in 2002, 2011, and 2014, revealing various safety and maintenance issues that were subsequently addressed. These violations included fire safety concerns such as an inoperable fire escape drop ladder, missing lobby smoke detector, and expired fire extinguishers in 2002 and 2011, as well as structural issues like the need for guardrails and handrails at rear exit stairs identified in 2011 and fire proofing repairs required in 2014. The building has seen important infrastructure improvements, including a $6,200 reroofing project in 2002 and a substantial electrical upgrade in 2003 that installed a 200-amp main service with four meters.

Recent maintenance activities (2022-2024) have focused primarily on exterior and access issues, with multiple 311 calls regarding overgrown trees blocking sidewalks, driveway blocking incidents, and a damaged side sewer vent cover reported in 2023. The property is currently involved in an open public works follow-up request from December 2024. Planning records indicate an approved Cottage Food Operator Bakery referral with the Department of Public Health, though the developer information is listed as "None." The building's ownership is recorded under Nancy Ying-nuan Su & Jack W, and all previously noted violations have been marked as not active, suggesting they were resolved appropriately at the time.

Risk rating

How 4344 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.

Neighborhood percentile
