Booking Insights
Caldwell guests book an average of 31.7 days in advance, with an average length of stay of 4.90 nights. The 32-day lead time is below the national STR median, giving operators moderate but shorter advance visibility. The shorter booking window may reflect the market’s significant share of business and relocation travelers who book closer to their stay date.
The 4.90-night average stay is above national norms, consistent with business travelers on extended assignments and leisure visitors making multi-day Treasure Valley trips. Minimum-stay policies of 3-5 nights are well-matched to actual demand. Operators should implement dynamic pricing for the June-August peak while offering flexible minimums in the January-February trough to maintain the 54-64% occupancy floor.
Short-Term Rental Regulations
Caldwell operates under Idaho’s statewide STR preemption law (ID Code 67-6539). No city permit, Canyon County permit, or registration is required for short-term rental operations. Idaho Governor Brad Little signed HB 583 on March 16, 2026, effective July 1, 2026, which expands the existing 2017 preemption statute to explicitly prohibit local permits, fees, density caps, owner-occupancy mandates, rental day limits, and reporting requirements specific to STRs.
The state lodging tax rate is 8.0%. Operators must collect and remit this tax on stays under 30 days. Local governments may still enforce health and safety standards that apply equally to all residential properties, including smoke alarms, fire extinguishers, and carbon monoxide detectors. No owner-occupancy or primary-residence requirement applies. No maximum nights per year cap exists. Enforcement is rated minimal. Idaho’s preemption framework is among the broadest in the nation as of mid-2026.
Market Comparison
Against national benchmarks of roughly 55% median occupancy and $220 median ADR, Caldwell’s April 2026 occupancy of 68.2% is 13 percentage points above the national median. The $145 ADR is below the national baseline by 34%, reflecting the affordable Idaho market. The rental demand score of 92.2 out of 100 is one of the highest in the dataset.
Premium Rentals leads with 70 listings, 2,380 reviews, and a 4.73 average rating. Boise BnB ranks second with 60 listings and 2,210 reviews (4.59 rating). Evolve holds third with 59 listings and 2,613 reviews (4.83 rating). The top three operators manage 189 listings combined in a market of approximately 3,446 total listings, with the large majority independently operated. The strong preemption-backed regulatory framework (score 63.5 out of 100) is expected to improve further as HB 583 takes full effect in July 2026.
