Summary
In unincorporated Grant County, a home occupation is allowed in any dwelling under Unified Development Code § 23.08.210, which lists permitted trades like artists, tailors, home crafts and small kennels, bars funeral homes and medical or veterinary clinics outside the Agricultural district, and treats an occupation with no employees and no signage as permitted outright without an approval process.
(a)Home occupations are subordinate to the primary residential use and are permitted in any dwelling unit and include, but are not necessarily limited to:(1)Artists and sculptors;(2)Authors and composers;(3)Dressmakers, seamstresses and tailors; ... (d)In addition to the standards applicable in the zoning district in which located, all home occupations shall be subject to the following standards:(1)A home occupation shall be conducted within a dwelling which is the bona fide residence of at least one (1) of the persons employed in the occupation or in an accessory building thereto which is normally associated with a residential use; ... (4)No more than two (2) persons at any one time other than a member of the immediate family occupying such dwelling shall be employed; ... (8)Any new construction to house the home occupation shall be limited in scale so that it is in character with neighboring properties. In no case shall more than one thousand (1,000) square feet of total building area on the property be devoted to the home occupation; ... (f)The granting of the proposed home occupation use shall not constitute a rezone.
Full Breakdown
Grant County's Unified Development Code treats a home occupation as subordinate to a residence and lists examples ranging from artists, authors and dressmakers to instructors, real estate agents, lawyers and small kennels housing five to ten dogs or stables boarding up to ten horses, all governed by UDO § 23.08.210(a). Certain uses can never qualify as home occupations anywhere outside the Agricultural district: funeral homes, medical or dental clinics and veterinary hospitals are barred under § 23.08.210(b). A home occupation with no employees, no sign, work performed entirely indoors and no outdoor storage, alteration or repair of materials or equipment is exempt from any approval process under § 23.08.210(c); every other home occupation must clear Development Services review against the baseline standards in § 23.08.210(d).
Those standards require the occupation to run out of the operator's bona fide residence or an accessory building normally associated with residential use, forbid exterior changes that make the property look non-residential, and cap outdoor wood storage at four cords for anyone selling firewood from home. No more than two people outside the operator's immediate family may work on site at one time, noise audible at the property line is capped at twenty continuous minutes for up to an hour a day if loud enough to be annoying, and newly built space devoted to the business cannot exceed 1,000 square feet.
Access must come from a county-standard road, and the Administrative Official can attach further conditions or amend the site plan to protect public health and safety. Approving a home occupation never rezones the parcel under § 23.08.210(f).
Violations & Fines
Grant County Development Services, the Sheriff's Office, the Public Works Director and the Prosecuting Attorney are all authorized to enforce UDO home occupation standards under GCC § 1.32.020. A confirmed violation, such as exceeding the two-employee cap or running a barred use like a veterinary clinic, is assessed at $500 per occurrence under GCC § 1.32.140, and repeat or uncorrected violations can lead to a stop work order, permit suspension under § 1.32.240, or revocation under § 1.32.250.
