Initial analysis

The property at 3439-3443 Balboa Street is a 2-story mixed-use building constructed in 1947, containing 3 residential units and ground-floor commercial space, currently owned by the John Loy Lam Revocable Trust. The building has undergone several significant modifications over the years, with the most pressing recent concern being a fire safety violation in October 2023 regarding blocked exits, which was subsequently abated. The commercial portion of the building has experienced multiple use changes, including a controversial transition from a beauty salon to a massage establishment in 2016, which generated complaints about unauthorized operations and required multiple permit modifications. The building has also seen various maintenance and improvement projects, including injection grouting work in 2016, porch remodeling in 2013, and multiple accessibility improvements between 2005-2006 including handicap access entry construction and toilet facilities.

Historical records show past concerns about structural and maintenance issues, including a 1999 complaint about deteriorating back stairs and windows, and several plumbing-related work orders. Recent activities from 2024 have primarily involved exterior maintenance issues such as garbage management and graffiti removal, as well as some parking-related concerns. The building's systems have been periodically updated, with electrical improvements including circuit panel replacements in 2005 and various other system upgrades over the years. While the property has had its share of maintenance and regulatory challenges, most recent issues have been promptly addressed, though the building's history suggests ongoing attention to both safety compliance and general upkeep has been necessary.

Risk rating

How 3439-3443 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.
