Initial analysis

The two-unit residential building at 3320-3322 Balboa Street in San Francisco's Outer Richmond neighborhood is owned by William and Maylan Wong and was constructed in 1956 as a two-story flats and duplex structure. The property has undergone several significant maintenance updates, including re-roofing work in 1997, 2016, and most recently, in December 2019, there was an attempt to legalize an unauthorized unit consisting of one bedroom, bathroom, and kitchen under Ordinance 43-14, though this permit was subsequently withdrawn. Planning records indicate a previous proposal to legalize a third unit at the ground floor behind the garage, which would have included modifications to the property's curb cut and parking configuration, though the current status of this project is documented as "Closed - Informational."

The building's recent history shows no significant safety concerns or major resident complaints, though there have been several maintenance issues in the surrounding area, including periodic graffiti incidents (most recently in 2024), street cleaning needs, and parking enforcement matters between 2011 and 2024. Notable external issues have included two incidents of loose garbage requiring clean-up in 2022 and 2023, and several graffiti cases on nearby infrastructure, including a parking meter and pole. While there have been multiple 311 calls recorded near the property, most relate to street conditions and parking issues rather than direct building concerns, and no tenant buyouts have been recorded at this address.

Risk rating

How 3320-3322 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.
