Ada Township Permits & TimelineWhat's Different About Bathroom Permits in Ada Township
Ada Township's permitting pathway is its own animal, and most Ada homeowners don't know the mechanics until they're in the middle of a project. Building permits and inspections are issued through Cascade Township — Ada contracts that work out. You submit the application and plans to Ada Township Planning and Zoning, the Zoning Administrator signs off on conformity with Ada's standards, water and sewer connection fees are paid where applicable, and the application then moves to Cascade Township for issuance and inspection.
Any bathroom remodel that relocates plumbing, adds or moves electrical circuits, or touches structural framing requires a building permit, with plumbing, electrical, and mechanical trade permits riding along. A purely cosmetic refresh — paint, a like-for-like vanity or fixture swap, no plumbing changes — usually does not. We confirm which side of that line your scope sits on during the in-home consultation.
There's a wrinkle specific to Ada: many properties — particularly larger lots along the Thornapple River and in less-dense Ada Township sub-areas — are on private wells, septic systems, or both. A like-for-like remodel that keeps the same fixture count usually doesn't touch the septic side. But a gut remodel that adds a fixture — a second sink, an added shower, or a new bathroom — can trigger a Kent County Health Department review for drain-field capacity and well-setback verification, on top of the township permit. We map that out in discovery so it's priced into the fixed contract and scheduled into the timeline, not discovered mid-build.
Thornapple handles every step of that pathway as part of the fixed-price contract — the Ada Planning and Zoning submittal, the Cascade Township coordination, the Kent County Health filing where it applies, and every rough-in and final inspection. You don't step into a township office. Full breakdown on our Grand Rapids remodeling permits page.
