Local FAQ
Home Additions questions in Allen
Do I need a permit for a home addition in Allen?
Permit requirements depend on the scope of work, for example whether you move walls, plumbing or electrical. Allen publishes its residential permit information on its own website, and that page is the authority. Bring your plans to the estimate and we will tell you what we expect to be required.

Cost depends on size, structural complexity and finishes. Ground-level additions are generally more economical than second stories. We provide a detailed fixed-price proposal after a free consultation.
Will an addition match my existing house?
Yes. We match brick, siding, roofing and trim profiles and align rooflines so the addition looks original.
Do I need HOA approval?
Most Collin County neighborhoods require architectural review. We prepare the drawings and submittals for you.
