Troutdale allows home occupations as an accessory use in residential zoning districts under Troutdale Development Code (TDC) Chapter 5.100 (Home Occupations), administered by Community Development. A home occupation is defined as a lawful occupation carried on in a dwelling by a resident of the dwelling where the occupation is secondary to the main use of the property as a residential dwelling. The TDC requires the use to remain clearly incidental and subordinate to the residential character of the property, conducted by household residents, with no external evidence of the business and no off-site impacts (noise, traffic, parking, signage beyond what is allowed). A Troutdale business license under Title 5 of the City Code is also required regardless of the home-occupation zoning approval.
The Troutdale Development Code, in its 2017 codified form most recently amended November 17, 2023, regulates home-based businesses through TDC Chapter 5.100 (Home Occupations), part of Chapter 5 (Miscellaneous Uses, Standards, and Exceptions). Section 5.100 defines a home occupation as 'a lawful occupation carried on in a dwelling by a resident of the dwelling' that is 'secondary to the main use of the property as a residential dwelling' and sets standards designed to keep the operation indistinguishable from a normal residential use. The chapter's standards require: (1) the occupation be conducted by members of the household residing in the dwelling, with limits on non-resident employees; (2) the occupation be carried on entirely within the dwelling unit (or an accessory structure where specifically allowed); (3) the dwelling retain its outward residential appearance, with no commercial display, no outside storage of stock or materials, and signage limited to the small nameplate allowed by the TDC sign standards in the underlying residential district; (4) the operation generate no noise, vibration, glare, fumes, odors, electrical interference, or other off-site impacts that would be detectable beyond the dwelling unit; (5) on-premises retail sale of stock kept for that purpose be limited or prohibited, with mail-order, internet-based, and service-based work generally favored over on-premises retail; (6) customer and client visits be limited so as not to generate traffic or parking demand inconsistent with the residential character of the neighborhood; (7) vehicle storage and use be limited so that commercial vehicles, trailers, and large equipment do not dominate the streetscape. Certain higher-impact uses (vehicle repair, restaurants serving the public, commercial kennels, and similar uses) are categorically inconsistent with the home-occupation definition because they cannot satisfy the no-off-site-impact standard and must operate in a commercial or industrial district. Even when the zoning standards of TDC 5.100 are satisfied, the operator must also obtain a Troutdale business license under Title 5 of the City Code through the City Recorder; the standard license fee is $80 per year on a calendar-year cycle. The Community Development Department (503-674-7230) administers TDC 5.100 zoning approval, and the City Recorder administers the business license; the two approvals run in parallel. Cottage food production and family day-care home uses are layered on top of TDC 5.100 with separate state licensing through the Oregon Department of Agriculture (cottage food) and the Oregon Department of Early Learning and Care (registered/certified family child care homes under ORS 329A); the state programs do not displace TDC 5.100 standards.
A home-based business that exceeds the TDC 5.100 standards (visible signage beyond the permitted nameplate, outside storage, customer traffic inconsistent with the residential character, non-resident employees beyond the chapter's limit, on-premises retail of stock, or off-site noise/odor/glare impacts) is a Troutdale Development Code zoning violation enforced by Community Development and the Code Compliance program. Enforcement begins with a notice of violation and opportunity to correct; continued non-compliance is referred to municipal court for civil penalties under the standard penalty provisions of Title 1 of the Troutdale Municipal Code. Operating without the required Troutdale business license is an independent violation enforceable by the City Recorder under Title 5 and triggers the $25 late fee plus city collection action. Categorically prohibited uses (vehicle repair, public-serving restaurants, commercial kennels) cannot be cured by application and must cease or relocate to a properly zoned commercial or industrial district. Where the home business produces noise, the Troutdale Municipal Code Chapter 8.24 (Noise Control) is the operative authority (see short-term-rentals/noise-rules for the citywide 10 p.m. to 7 a.m. nighttime window and plainly-audible standard), and persistent nuisance impacts are independently abateable under TMC Chapter 8.28 (Nuisances).
