Real Client Experience: Navigating Complex Permit Requirements
When Sarah and Mike contacted us about their master bathroom remodel, they thought they just needed to “update the look” with new tile and fixtures. During our initial consultation, we discovered their vision actually involved significant changes that would require multiple permits.
Their wish list included:
- Moving the toilet to create space for a larger shower
- Adding a skylight for natural light
- Installing heated floors throughout
- Creating a double vanity with additional lighting
- Adding a ventilation fan connected to existing ductwork
We explained that their “cosmetic update” actually required electrical, plumbing, and structural permits due to the fixture relocations, new electrical circuits, and skylight installation.
