Chatham-Kent modular homes — FAQ
Can you build a detached ADU on a rural Chatham-Kent lot?
It depends on servicing. On a fully-serviced lot (municipal water + sewer), a detached ADU is as-of-right. On a rural-residential lot the detached option requires municipal water — a private-well lot isn’t eligible as-of-right (you can still add a unit inside the dwelling). On agricultural (A1) land, only an attached unit is permitted; a detached second dwelling runs through a rezoning. Check your address.
How big can an ADU be in Chatham-Kent?
There’s no fixed m² cap — a detached suite is limited by the 10% accessory-building lot coverage and the 6.0 m height, set back 0.6 m from the side and rear. Check your address for the practical number.
Can you put a modular home in Chatham-Kent?
Yes. On land you own, a modular home on a permanent foundation is legal residential housing under the Ontario Building Code throughout Chatham-Kent, subject to standard zoning and permits.
