Sub scheduling is where Dallas projects lose days. Core lesson: plan mechanical and plumbing together at rough-in, and together again at finals, so crews and the inspector line up and you pass the first time.
Dallas Development Services states that, effective June 1, 2026, all commercial, residential, and multifamily projects must schedule plumbing and mechanical rough inspections together on the same day, and schedule plumbing and mechanical finals together once ready for final inspection.
What this means for a 30x60 shop with HVAC and a restroom: sequence trades to be ready on the same day, confirm access and test points, and label everything cleanly on site. Do this when you build the schedule, not the night before inspections.
Checklist:
1) Put combined M/P roughs and finals on your master schedule.
2) Confirm both trades are complete and present before you call.
3) Stage fixtures, caps, gauges, and access panels for the inspector.
DM INSPECTION PLAN with your project dimensions, intended use, and Dallas ZIP for a quick combined-inspection sequence you can hand to your subs.
