What Allen says

Current status: Allen's zoning has historically not permitted independent secondary dwelling units on single-family lots. If your goal is a true rentable ADU, Allen is not currently the place.

The catch most people miss

Rules change — Texas cities revisit ADU ordinances every year, and a statewide bill may return in the 2027 legislature. Leave your email and we'll tell you the day Allen's rules move.
