Questions people ask
How much does a garage permit cost in Allen?
Permit fees established by resolution of City Council; plan review fees apply in addition to permit fees. Valuation-based fees mean the number depends on what the job is worth, so the department quotes it when you apply.
I already built it without a permit. What now?
Allen can issue a stop-work order and require you to apply after the fact, sometimes with an extra fee. Work that was covered up may have to be opened for inspection. Full walkthrough here.
