Tigard, OR Home Business: Zoning Restrictions (2026)

Tigard regulates home-based businesses through Chapter 18.760 (Home Occupations) of the Tigard Community Development Code (Title 18). The chapter applies to any accessory commercial use associated with a primary Household Living use in a residential base zone. A home occupation must be conducted only by a principal occupant of the dwelling unit. The use must be operated entirely within the dwelling unit or a conforming accessory structure; the maximum floor area used for the home occupation and associated storage is 25 percent of the combined residence and accessory-structure floor area or 528 square feet, whichever is smaller. A dwelling unit may host more than one home occupation provided the combined floor area stays within the limit; each home occupation must apply for a separate home occupation permit if required by the chapter. Supplier deliveries to the residence are limited to 3 per week. Exterior storage of commercial vehicles as defined in the Oregon Vehicle Code is prohibited, with a single exception: one commercially licensed vehicle of not more than 0.75 ton gross vehicle weight (GVW) may be parked outside a structure. Additional off-street parking beyond the existing residential requirement is not required for a home occupation. The chapter distinguishes Type I and Type II home occupations, with the Type II permit processed under the Type II land use review procedure in CDC 18.710.060; Type II is the path for home occupations involving customer or employee activity that exceeds the more restrictive Type I baseline. A separate City of Tigard business license under TMC Chapter 5.04 is required in addition to the CDC 18.760 home occupation permit. CDC 18.760 should be reviewed alongside the applicable base zone (e.g., R-1, R-2, R-3.5, R-4.5, R-7, R-12, R-25, R-40 under Title 18) because the base-zone rules control the underlying residential use and may impose additional standards on accessory commercial use.
