Long cooling seasons and heavy summer rain drive the two problems we see most here: moisture getting into assemblies, and anything that traps it staying wet.
Garage conversions read as the cheap route and often are, but the slab usually sits below the required floor height and lacks a moisture barrier, so the real scope includes the floor system most quotes leave out.
Utilities are the line item that surprises people: whether your existing panel and sewer lateral can carry a second dwelling, or whether you are trenching to the main.
What the job includes
