Summary
Benton County treats a short-term rental of an ordinary dwelling as a home occupation under BCC § 51.020(12), which pulls in the home occupation rule that the use must produce no noise, odor, vibration, glare, or fumes detectable outside the structure, under BCC §§ 91.205, 91.210 or 91.215 depending on lot size.
This type of use is distinct from a short-term rental use (defined as rental of a dwelling for less than a 1-month period) which is considered a home occupation and allowed subject to the applicable standards for home occupations in this code. ... (3)Produce no noise or obnoxious odors, vibrations, glare, or fumes detectable to normal sensory perception outside the structure;
Full Breakdown
Instead of writing a standalone short-term rental ordinance, Benton County's Development Code definition of "Dwelling" folds short-term rental in directly: a rental of a dwelling for less than a one-month period is defined as distinct from ordinary residential use and is treated as a home occupation, subject to the same standards as any other home business. 215(3) governs lots over five acres, and all three use the same zero-tolerance language, barring noise or obnoxious odors, vibrations, glare, or fumes detectable to normal sensory perception outside the structure.
Because it's classified as a home occupation, a short-term rental is also subject to the same floor-area caps, the 10-trip-per-day traffic limit, and, if operated outside the home, the two-year permit renewal. 050(11) bans short-term accommodation outright for both the primary dwelling and the ADU, so the noise-and-nuisance standard described here only applies to a stand-alone dwelling being rented short-term, not an ADU parcel.
Violations & Fines
A short-term rental generating noise, odor or other nuisance detectable outside the structure is a home occupation standards violation, enforced by Community Development and Code Compliance under Chapter 31. The escalating process runs from a verbal notice through a written notice to comply and, if uncorrected, a stop-work order or infraction complaint with a fine up to $500 per violation and up to $1,000 for a continuing violation (BCC §§ 31.020, 31.125(3)).
