ADU & In-Law Suite Construction in Old City

An ADU is a complete second home on your lot — its own kitchen, bath, and entrance — and in Florida it is the go-to for multigenerational living and rental income. We confirm your lot is buildable, build to the FBC with wind/HVHZ compliance, handle egress and utilities, and stand for the inspections so the unit is a legal, storm-ready dwelling.
