    The county's permit forms list a Health Department Site Evaluation Request as required with the building permit, so the septic and well review starts at the same time as the house permit on an unsewered lot.

Building in Kendall County: common questions

Who builds barndominiums in Kendall County?
We do. We supply barndominium kits, custom plans, pole barn homes and turnkey builds for owners across unincorporated Kendall County. Send us the parcel and we will check the zoning, scope the build and give you a price range.
Can I build a barndominium on a small farm parcel in Kendall County?
It depends on the parcel's allocation. On agriculturally zoned land the county generally allows one home per 40 acres, with exceptions for lots that existed before 8 March 1977 and a few other cases. Confirm the allocation with Kendall County Planning, Building & Zoning before you buy.
Do I need a building permit for a barndominium in Kendall County?
Yes. In the unincorporated county, the Building Division issues the permit under the 2024 International Residential Code adopted effective 11 May 2026, and a Health Department site evaluation is required with the permit. Inside a city or village other than Millbrook and Plattville, the municipality issues the permit.
How much does a barndominium cost in Kendall County?
Size, finish level, foundation and site work (well, septic, driveway) drive the number. We price each build against your parcel after a free survey rather than quoting a flat figure.
