Initial analysis

The three-story multi-family residential building at 720-722 Arguello Blvd in the Lone Mountain neighborhood is a 2-unit structure built in 1906, currently owned by the Karen Lum Revocable Trust. The property has experienced significant incidents, most notably a serious fire in April 2015 that affected the back of the top unit (#720), causing damage to the bedroom, kitchen, and roof areas requiring $30,000 in repairs. This incident was preceded by complaints about building modifications beyond approved permits. Earlier maintenance issues were documented in 1998, including roof leaks, stair damage, and inadequate heating, though these were resolved by 1999. The building underwent various improvements over the years, including dry rot repairs to the deck and staircase in 2015, reroofing in 2000, and a horizontal addition completed in 1999.

Recent history (2021-2024) shows consistent street safety and maintenance issues around the property, including multiple reports of loose garbage, parking violations, and abandoned vehicles, though these are not directly related to the building's condition. Of particular note is the property's recent history with unauthorized short-term rentals, with violations documented under both unit addresses, resulting in penalties referred to the Bureau of Delinquent Revenue. The building's maintenance record shows regular upkeep but also reveals some recurring issues, particularly with stairs and exterior elements, suggesting ongoing structural maintenance needs.

Risk rating

How 720-722 Arguello Blvd'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
