Initial analysis

The two-unit residential building at 326-328 Irving Street in San Francisco's Inner Sunset neighborhood is currently undergoing significant upgrades and modifications, with the most substantial project being a proposed conversion of the ground floor vacant space into two additional dwelling units (ADUs), which is currently under review. This conversion project, if completed, would increase the building's total unit count to four and includes plans for ceiling upgrades to meet fire safety requirements and basement sprinklers. The property has seen considerable improvement work in 2023, including voluntary seismic upgrades with new shear walls, concrete slab work, and stair replacement valued at $62,000. Multiple interior improvements were completed earlier in 2023, including kitchen and bathroom remodels in both units, window replacements, and complete rewiring of units, with associated plumbing and electrical work.

The building's maintenance history shows attention to structural integrity and safety, with recent installations of a heat pump system (February 2024) and necessary gas and electrical modifications to support new appliances and systems. Historical records indicate past issues such as a sewage backup in 2015 and various graffiti incidents, mostly occurring on utility poles rather than the building itself. External maintenance work has included reroofing in 2007 and emergency repairs to the rear deck in 2002. The property has had several 311 calls related to general neighborhood issues such as parking violations, hazardous materials, and street cleaning, though these are primarily related to the surrounding area rather than the building itself. The most recent permits and improvements suggest ongoing efforts to modernize the building while addressing seismic safety and habitability requirements.

Risk rating

How 326-328 Irving 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.

Neighborhood percentile

Out of 1493 buildings in this neighborhood, 0 are predicted to be safer.

12-Month severity forecast
