MO HB1791

Establishes six levels of building permits based on property type and size, ranging from small residential projects under 7,500 square feet to CDBG-DR disaster recovery permits

Requires political subdivisions to approve, conditionally approve, or deny permits within specified deadlines: 30 business days for Level 1, 60 business days for Levels 2-4, 12 business days for Level 5, and 10 business days for Level 6

Mandates a 10% reduction in permit fees for each business day a political subdivision misses a deadline, with a 20% daily reduction if deadlines are missed after applicant submits requested revisions

Requires political subdivisions to notify applicants within 5 business days of any missing information needed to complete an application; failure to provide notice results in automatic acceptance of the application

Allows contractors in governor-declared disaster rebuilding areas to begin work without a permit, provided they apply for the required permit within 30 days of starting construction
