Tips
- Manual D, J, and S calculations must be submitted with new residential building plans prior to plan review, per the City's Oct. 1, 2021 policy notice.
- Every fifth home a builder constructs is subject to mandatory blower-door thermal-envelope testing under the 2018 Idaho Administrative Code amendments.
- The City of Pocatello issues and reviews mechanical/HVAC permits itself; a mechanical permit is a City-issued building permit, so the City is bound by Idaho Code § 39-4117 (added 2025 ch. 272), which requires written notice of the completeness determination within 10 business days for a residential building permit application and 20 business days for a commercial one. This is a statutory completeness-review deadline, not a full-approval deadline (the statute states a completeness determination 'shall not constitute approval but shall authorize the application to proceed to formal plan review'). DOPL publishes no separate mechanical-permit turnaround because Pocatello self-administers mechanical permits.
