Verified from official government sources
Caldwell has no short-term-rental-specific permit in its City Code, and Idaho law sharply limits what the city could require. Idaho Code 67-6539 bars cities from prohibiting STRs and classifies them as residential land use. Under HB 583 (effective July 1, 2026) cities may not require any STR license, fee, permit, certification, or registration.
Short-term rentals in Caldwell follow the same noise rules as every property. City Code 07-13-03 bars loud or offensive noise plainly audible 150 feet from the source between 11:00 p.m. and 7:00 a.m. Idaho law (67-6539) lets cities apply these generally applicable noise rules to STRs, and HB 583 confirms STRs must comply with noise and nuisance ordinances.
Caldwell imposes no STR-specific city fee, and HB 583 bars one as of July 1, 2026. Stays of 30 days or less owe Idaho's 6% sales tax plus the 2% Travel and Convention Tax (8% total). Caldwell sits outside the Greater Boise Auditorium District and is not a resort city, so no extra local lodging tax applies.
Caldwell imposes no extra off-street parking on short-term rentals. As a residential land use under Idaho Code 67-6539, an STR is subject only to the same parking standards as any home. HB 583 (effective July 1, 2026) bars cities from requiring additional parking for STRs beyond what applies to all residences.
Caldwell sets no short-term-rental-specific occupancy cap. Under Idaho Code 67-6539 an STR is a residential land use, so it is subject only to the occupancy standards that apply to any dwelling. HB 583 (effective July 1, 2026) lets cities apply occupancy limits tied to International Building Code standards, but only if applied equally to all residences.
Caldwell does not require short-term rental operators to carry special liability insurance, and Idaho law prohibits such a mandate. HB 583 (effective July 1, 2026) bars cities from requiring additional insurance for short-term rentals. Hosts should still carry their own coverage as a business precaution, but it is not a city requirement.
Caldwell does not cap the number of nights a property may be rented short-term, and Idaho law forbids such limits. Idaho Code 67-6539 bars ordinances that effectively prohibit STRs, and HB 583 (effective July 1, 2026) prohibits cities from restricting rental days or capping the number of short-term rentals. Year-round operation is allowed.
Caldwell does not require short-term rentals to register with the city, and Idaho law prohibits it going forward. HB 583, amending Idaho Code 67-6539 effective July 1, 2026, bars cities from requiring any registration, license, certification, or permit to operate an STR. Operators register only with the Idaho State Tax Commission for lodging taxes if renting outside a marketplace.
Caldwell does not require a host or manager to be present or on-site during short-term rental stays, and Idaho law bars such mandates. HB 583 (effective July 1, 2026) prohibits cities from requiring professional property management or owner presence for short-term rentals. Whole-home, unhosted rentals are allowed.
Caldwell does not require a short-term rental to be the host's primary residence, and Idaho law forbids such a rule. Idaho Code 67-6539 treats STRs as residential land use, and HB 583 (effective July 1, 2026) bars cities from imposing owner-occupancy or primary-residence requirements on short-term rentals.
