Can I enclose my patio in McKinney?
Yes, on a permit. McKinney's packet describes a patio cover as open on at least two sides and treats anything attached to the house as part of the house, so a walled-in patio has to meet the house's setbacks. A roofed room over 200 square feet needs engineered drawings, and the energy reports come from a third-party inspector before the final.
Walls change what McKinney calls it
McKinney sorts backyard work into accessory uses, accessory structures and accessory buildings. A patio enclosure starts in one group and ends up in another.
- Pergolas, arbors, patio covers and shade structures are accessory structures, which the packet describes as open on at least two sides. Close in the sides of a patio cover and it no longer fits that description. City of McKinney Patios, Pergolas, Sheds and Accessory Structures Alteration, Residential Packet, effective October 1, 2025, Definitions
- Accessory structures attached to the house are treated as an extension of the house. Anything physically joined to it must meet the same setbacks as the main house, and the packet tells owners to call the city to confirm the setbacks for their lot. City of McKinney Patios, Pergolas, Sheds and Accessory Structures Alteration, Residential Packet, effective October 1, 2025, Definitions and setbacks
- The packet says permits are required when building, remodeling or enlarging a building. Painting, wallpaper, carpet, cabinets and trim do not need one. City of McKinney Patios, Pergolas, Sheds and Accessory Structures Alteration, Residential Packet, effective October 1, 2025, FAQ, When is a permit required?
- The city gives its own reasons to permit the work. Homeowners insurance may not pay for damage caused by work done without permits and inspections, and listing associations require sellers to disclose improvements and repairs. City of McKinney Patios, Pergolas, Sheds and Accessory Structures Alteration, Residential Packet, effective October 1, 2025, FAQ, Why do I need a permit?
- McKinney does not enforce deed restrictions or HOA rules, so an HOA's approval is a step the owner has to get on its own, apart from the city permit. City of McKinney Patios, Pergolas, Sheds and Accessory Structures Alteration, Residential Packet, effective October 1, 2025, General requirements

Drawings and engineering
- Any structure over 200 square feet with a roof deck, attached or not, needs engineered construction documents. Roofed means a solid roof, not open rafters. City of McKinney Patios, Pergolas, Sheds and Accessory Structures Alteration, Residential Packet, effective October 1, 2025, FAQ, When is engineering required?
- A structure made of aluminum or steel must be engineered whatever its size, so a metal-framed sunroom kit needs an engineer too. City of McKinney Patios, Pergolas, Sheds and Accessory Structures Alteration, Residential Packet, effective October 1, 2025, FAQ, When is engineering required?
- For a walled building the packet lists a foundation plan, framing plans, a floor plan with the walls, doors and windows, front, side and rear elevations with materials and height, and the energy code compliance documents. City of McKinney Patios, Pergolas, Sheds and Accessory Structures Alteration, Residential Packet, effective October 1, 2025, Accessory buildings
- The designer's certification letter, which states that the plans meet McKinney's adopted codes and regional amendments, is not required for additions, renovations and alterations under 1,000 square feet. City of McKinney Residential Builder Packet, Designer's Certification Letter

The fee, the energy reports and the work hours
- McKinney's builder packet charges additions and alterations 68 cents for each gross square foot of the addition, or of the area the alteration touches. That is a city fee, not our price. City of McKinney Residential Builder Packet, Building permit fees
- The builder packet lists a final energy inspection report, approved by a third-party inspector, among the reports the city requires. The energy testing certificate comes at completion, before the final inspections. City of McKinney Residential Builder Packet, Required reports and energy forms
- Construction is allowed Monday through Friday from 6 a.m. to 9 p.m., Saturday from 8 a.m. to 5 p.m., and Sunday from 1 p.m. to 5 p.m., in every zoning district. City of McKinney Residential Builder Packet, Allowable construction hours

McKinney Questions
What people in McKinney ask us
Is a patio enclosure just a patio cover permit in McKinney?
No. McKinney's patio cover is open on at least two sides. Once the sides are closed and the room is joined to the house, the city treats it as part of the house, with the house's setbacks.
My cover runs close to the back fence. Can it still be enclosed?
Maybe not all of it. An attached room has to meet the main house's setbacks, which can be deeper than where an open cover was allowed. We confirm the setback for your lot with the city before we draw a wall.
Will my McKinney enclosure need an engineer?
If it is roofed and over 200 square feet, yes, and an aluminum or steel room always does. Our drawings carry the engineering either way, so the question does not stall the permit.
Who checks the insulation and windows?
A third-party energy inspector. McKinney wants that inspector's final report, and the energy testing certificate, before the final inspections can close the permit.
How long does a patio enclosure take in McKinney?
Most run 3 to 6 weeks on site once the permit is issued. Windows on order and a post that has to come out are the usual reasons it runs longer.
What does a patio enclosure cost in McKinney?
The length of the new walls, the windows and door, the cooling, whether a post comes out and how the outside is matched move it most. It is priced in writing after a site walk; the price does not move unless the scope does.
