Initial analysis

The three-story multi-family residential building at 2001-2019 Balboa Street in San Francisco's Central Richmond neighborhood, owned by Lee Aaron Cin-hung, was constructed in 1921 and contains 8 units with ground-floor commercial space. The building has undergone several significant renovations and repairs over the past two decades, including a complete electrical upgrade in 2004-2007 with installation of new panels, lighting, and receptacles valued at over $25,000, a $18,500 reroofing project in 2017, and various plumbing improvements including sewer repair work in 2013. The property experienced multiple building violations in 2002 related to fire safety and building maintenance, all of which were resolved by October 2002.

More recently, there have been several concerning issues regarding the building's historic windows, with complaints filed in 2023 about unauthorized awnings and banners covering the windows, specifically involving a "Balboa Bubbles" awning and "iHairbook" banner. These violations have been submitted for enforcement action through planning records. Additionally, there is currently an active complaint from February 2023 regarding non-compliance with the vacant or abandoned commercial storefront ordinance. The building's maintenance history shows regular upkeep of essential systems, though there have been recurring issues with street cleaning and garbage overflow as evidenced by multiple 311 calls in early 2025. Two routine inspections in 2002 and 2015 show the property has undergone regular oversight, and previous water leakage issues between floors were addressed in 1996. The most recent building permit activity from 2018 involved the formalization of additional addresses (2015, 2017 Balboa Street) for the commercial portion of the property.

Risk rating

How 2001-2019 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.
