ADU Construction · Bastrop County, Texas
In Texas, a ADU Construction requires a building permit.
An accessory dwelling unit (ADU) always requires a building permit because it adds a habitable dwelling, including electrical, plumbing, mechanical permits and egress/zoning review. Plans are reviewed under the Statewide (local may exceed) code (IRC 2021); apply through Bastrop County Development Services before work begins.
