Full Breakdown

MCA 50-60-203 grants the Montana Department of Labor and Industry authority to adopt and enforce a state building code based on the International Code Council's I-Codes. The adopted Montana State Building Code requires residential pools deeper than 24 inches to have barriers at least 48 inches tall, self-closing self-latching gates, and pool covers or alarms in some configurations. Local certified building departments enforce these provisions; uncertified jurisdictions default to state inspection. Cities may adopt stricter requirements but cannot reduce the statewide minimum barrier height or hardware specifications.

Violations & Penalties

Construction without compliant barriers violates MCA 50-60-214 with stop-work orders, fines up to $500 per violation, and required corrective installation before occupancy.
