Building a new detached or attached garage is treated similarly to a major home addition. It involves pouring a concrete slab, structural framing, roofing, and electrical work. Due to zoning laws governing property setbacks and impervious surface limits, the permitting process for garages is highly rigorous.
Given that Montgomery County has a densely packed population of 1,065,949 residents, the local building department frequently experiences high application volumes. Expect processing times of 4 to 8 weeks for standard residential projects.
