Initial analysis

The property at 3620-3624 Balboa Street is a mixed-use building constructed in 1927, containing 4 residential units plus retail space, and owned by Kathryn Pik Kwan Wong. The building's maintenance history shows regular upkeep, including a significant $40,000 ADA-compliance bathroom renovation completed in 2024, a $10,000 reroofing project completed in 2019, and various repairs in 2017. A notable incident occurred in 2017 when unauthorized construction led to a building violation regarding an improper roof addition, which was subsequently removed per compliance orders. More recently, in late 2024, there have been multiple water-related issues, including complaints about water infiltration affecting neighboring properties and reports of sewage discharge, though these have been addressed according to city records. The property has experienced some operational challenges, including complaints about excessive noise from construction work and service disruptions from nearby businesses. Historical records show attention to safety concerns, with a blocked exit issue being promptly corrected in 2007. The building's recent permit activity and complaint resolution patterns suggest ongoing maintenance and compliance efforts, though some infrastructure issues remain a recurring theme.

Risk rating

How 3620-3624 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.
