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.
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.

- Plan sets and permit submittal
- Detached, attached and garage conversions
