Idaho Falls, ID Short-Term Rentals: Noise Rules (2026)

The City of Idaho Falls does not have a noise rule written only for short-term rentals. Noise at an STR is governed by the same nuisance and noise provisions that apply throughout the city, and the responsibility for compliance is placed squarely on the operator. The city's Short-Term Rentals FAQ states that the property owner is "responsible to ensure that their property is in continued compliance with city regulations," and specifically includes "nuisance issues such as noise" in that obligation. There is no published STR-specific quiet-hours window, decibel limit, or audibility standard unique to short-term rentals; instead, the general city nuisance code and any applicable noise provisions apply equally to STR guests and permanent residents. Idaho Code 67-6539 authorizes cities to "implement such reasonable regulations as it deems necessary to safeguard the public health, safety and general welfare in order to protect the integrity of residential neighborhoods," which is the legal basis for applying ordinary noise and nuisance rules to STRs. Idaho's tightened STR preemption (House Bill 583, 2026) confirms that cities retain authority over generally applicable noise, nuisance, and curfew rules so long as they impose no greater restriction on STRs than on comparable single-family dwellings. The practical guidance for an Idaho Falls host is to manage guests so that amplified music, parties, and late-night disturbances do not rise to a nuisance, because the host, not just the guest, is accountable for the property's continued compliance.
