Washington County, UT Noise Ordinances: Amplified Music & Outdoor Sound (2026)

Section 10-13-23(O) of the Washington County Code treats amplified sound equipment as a licensing condition for Short Term Rentals rather than a general noise permit. Any sound system or exterior speaker used at an STR must be permanently installed and fitted with a volume limiter; the code flatly states that no other sound systems or exterior speakers are permitted, which rules out portable Bluetooth speakers, rental PA systems, and DJ equipment brought in for an event. ) and to keep volume at or below the decibel ceilings set in § 10-13-23(M): 55 dB at the property line overnight and 75 dB during the day.

Compliance is not self-certifying: the same subsection requires the owner or manager to monitor sound system use and volume, retain that monitoring data for 90 days, and hand it over to the county within five business days of a request in an easily accessible format. Failing to produce the records is a violation by the terms of the ordinance itself, independent of whether an actual noise complaint was substantiated. The rule sits inside the broader Events; Parties; Noise framework of § 10-13-23(M), which also bans live music, disc jockeys, and portable PA systems as indicators of a prohibited event or party at an STR, reinforcing that amplified sound at these properties is tightly restricted rather than merely discouraged.
