Tips
- A deck, patio cover, storage shed, or open carport under 400 sq ft that is accessory to a residence has a flat $50 permit fee regardless of construction cost.
- Remodel valuation must reflect actual labor and material cost, not a square-foot schedule — keep contractor invoices/estimates on hand for permit intake.
- Confirm with City of Grand Junction Planning (970-244-1430) whether a City zoning/setback review applies before finalizing addition plans, since the county issues the building permit but City zoning still governs setbacks within city limits.
