Miami-Dade County
GENERAL CONTRACTOR IN MIAMI
Condo interiors and older single-family homes, permitted the Miami-Dade way.
Miami has the strictest product-approval and inspection environment we work in, and condo buildings add their own rulebook on top. That is exactly why homeowners here call a licensed general contractor instead of assembling trades themselves.

What Miami homes throw at us
We price the house you actually have
Before we quote anything, we look for the conditions that turn a clean renovation into a change-order nightmare. These are the ones we find most often here.
- Condo interiors requiring board approval, insurance certificates and work-hour compliance
- Older homes with cast-iron waste lines that need lining or replacement
- Miami-Dade NOA product approval required on every impact window and door
- Tile-over-tile floors and prior owner work that has to be corrected before finishing
Permits & approvals in Miami
Permits run through the City of Miami or Miami-Dade County depending on your address, with Miami-Dade product approval on openings and roofing. Condo work also needs a board-approved packet, elevator scheduling and proof of insurance naming the association.

“We had water damage behind a wall that two other contractors misdiagnosed. 12X found it in an hour, handled the drying, rebuilt the drywall, and dealt with the insurance paperwork.”
“Pavers, a pergola, an outdoor kitchen, and turf — done in five weeks and permitted properly. Our backyard is the reason we stopped talking about moving.”
“We turn over rental units on tight deadlines. They have never once missed a make-ready date, and their punch lists are cleaner than anyone we've used.”
