Initial analysis

This two-unit residential building, located at 1621-1623 McAllister Street in the Park North neighborhood, is a two-story flats and duplex structure built in 1900 and currently owned by Robert N. Middleton. The property underwent significant improvements and upgrades in 2013, totaling approximately $145,700 in construction costs, including foundation and lateral strengthening, rear facade modifications, and comprehensive kitchen and bathroom remodeling. The building received substantial electrical upgrades including a complete electrical remodel and 200-amp service upgrade, along with extensive plumbing improvements featuring new water heaters, fixtures, and gas fireplaces. A notable safety enhancement was completed in 2013 with the installation of one-hour fire-rated walls on both floors.

The property has encountered several regulatory and compliance issues, most notably in March 2015 when unpermitted gate installation prompted violation notices and abatement proceedings, though these are now marked as not active. Recent history shows the building has experienced some environmental challenges in its vicinity, with multiple 311 calls in 2024-2025 regarding garbage, debris, and encampments near the property, though these are external to the building itself. The building has had three documented fire incidents, all of which were either unintentional alarm activations or were found to have no actual fire or carbon monoxide presence, with no civilian injuries reported in any of these events. While the property has undergone numerous structural and safety improvements, prospective residents should be aware of the building's history of regulatory compliance issues from 2015 and the recent environmental challenges in the surrounding area, though these are primarily street-level concerns rather than building-specific issues.

Risk rating

How 1621-1623 Mcallister 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.
