Initial analysis

The multi-family residential building at 327-329 West Portal Avenue, constructed in 1933, is a three-story flat & store property containing three residential units plus commercial space. The building has undergone several significant improvements over the past two decades, including multiple roofing projects (2012, 2017) totaling over $11,500 in work, and major heating system updates with the replacement of wall furnaces in all units (2018) and decommissioning of a steam boiler (2019). The commercial space has seen recent activity with a change of use from limited restaurant to full restaurant in 2021, and ADA compliance improvements in 2019 including new store slope entry and door installation.

The property has experienced various maintenance and compliance issues typical of its age and mixed-use nature. A sewage backup incident was reported and resolved in May 2022, and there was one significant building complaint in 2002 regarding unauthorized kitchen installation work with extended hours, which was promptly abated. Recent activities around the property have included street cleaning and graffiti removal (2023-2024), with an open issue related to tree root damage to sidewalks reported in February 2023. The building's systems and infrastructure have received regular attention, with an emphasis on compliance with modern standards, as demonstrated by the ADA accessibility upgrades and removal of outdated heating systems. The property's commercial components have required special attention to permit compliance, evidenced by a 2011 fire complaint regarding operating without a permit that was found to have no merit.

Risk rating

How 327-329 West Portal 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.
