Pasco, WA Home Business: Zoning Restrictions (2026)

Home-based businesses in Pasco are regulated as "home occupations" under PMC Chapter 25.150, which permits the conduct of business as a use accessory to an established residence within a residential district. The defining zoning limits are spatial and operational. A home occupation may not occupy more than 20 percent of the gross floor area of the residence; however, all of an attached or detached garage may be used for the home occupation provided the area used does not exceed 600 square feet. The business must be clearly secondary to the residential use. Home occupations must be conducted solely by persons residing within the dwelling unit on the premises, limiting outside employees. Operational standards in PMC 25.150.040 restrict client access: client visits are limited to four hours per client per day, visits may only occur between 8:00 a.m. and 8:00 p.m., no more than two client vehicles may be on site at any given time, and no more than eight customer vehicles may visit the dwelling in a given day. Home occupations must not generate light or glare, vibration, fumes, or odors, or create conditions that annoy, injure, or endanger the comfort, health, or property enjoyment of neighboring residents. These standards keep the residential character of the neighborhood intact while allowing low-impact home businesses.
