What affects the price

The materials you choose—from siding to kitchen finishes—also change the math significantly. Whether you’re building a detached unit or converting an existing garage shifts the permit requirements and structural work needed. We provide exact pricing confirmed free on the call.

Frequently asked in Topeka
What exactly is an accessory dwelling unit in Topeka?
In Topeka, an accessory dwelling unit, or ADU, is a secondary housing unit on a single-family residential lot. It's essentially a smaller, independent living space. This could be a detached structure in your backyard or an addition to your existing home. The key is that it provides basic living facilities like a kitchen, bathroom, and sleeping area. It's a practical way to add living space without subdividing your primary lot.
