Initial analysis

The Simpson Family Trust's duplex property at 415 Parker Avenue in the Lone Mountain neighborhood is a two-story multi-family residential building constructed in 1986. The building's maintenance record shows several significant projects over the years, including a completed reroofing in 2006, installation of gas fireplaces in 2010, and patio wood repairs in 2009. A notable building complaint was filed in June 2011 regarding common area lighting, coin-operated washer/dryer connections, and a possible unauthorized unit, though this complaint is currently listed as not active.

Recent activity at the property has been predominantly related to parking enforcement issues, with multiple citations issued between 2023 and 2024 for vehicles blocking driveways. The building's maintenance record shows some cancelled permits, including a 2017 window replacement project and an earlier 1985 flooring installation permit. The most recent permitted work appears to be a window replacement project, completed by the Simpson Family Trust, focusing on upgrading street-facing windows to aluminum clad materials. The property's historical records confirm its original construction as a two-family dwelling in 1985, and the building has maintained its classification as a flats and duplex structure since then.

Risk rating

How 415 Parker Ave'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.
