Overview

The historic Loring Building is a prominent, three-story mixed-use property constructed in 1890 and remodeled for modern professional and retail use. The building includes a ground-floor space designed to support restaurants and arts and crafts, with the first and second floors configured for law firm use.

The property is located in Downtown Riverside at 3673 Main Street and overlooks the historic Downtown Riverside area and the Mission Inn.

As a rental opportunity, the Loring Building offers a practical split between street-level activity and professional office space, with restaurant-oriented requirements supported at the ground floor and dedicated, law-firm-suited space on the upper levels. The City of Riverside is also actively considering an Adaptive Reuse Ordinance that could, subject to approvals, create additional pathways for residential, hospitality, and other mixed-use conversions. For tenants or operators seeking a historically significant downtown address with defined space types across the building, this property provides a clear configuration for restaurants and legal uses within the same asset.
