Additions are the most permit-intensive residential work, and Allen reviews carefully. Here's the shape of it.
What's typically required
- A building permit with a full plan set — architectural, structural, energy.
- Structural engineering for new loads and the tie-in.
- MEP details, and HOA review where applicable.
Why we permit first in Allen
We finalize design, complete engineering, and get the permit approved before demolition — the single rule that prevents the most common addition delays, part of The AG Standard. Start with room additions in Allen.
