The short answer
- Removing or changing a load-bearing wall is structural work and needs a building permit, usually with an engineer's design.
- Many interior walls in Florida homes support roof trusses or beams, and some are concrete block. Don't assume a wall is non-structural.
- Even a non-structural wall can hide plumbing, electrical or air conditioning ducts, which bring their own permits.
- Structural work is excluded from Florida's 2026 small-project permit exemption.

Open floor plans are one of the most requested Florida remodels, especially in homes built in the 1970s through 1990s with closed kitchens. Taking out a wall can transform a house, but it's also where cutting corners can be dangerous.
Load-bearing walls need a permit
Removing, shortening or opening a load-bearing wall is structural work. Florida building departments require a permit, and most require a design from a Florida-licensed engineer or architect for the beam or header, its supports and how loads reach the foundation. Structural work is excluded from the 2026 small-project permit exemption, whatever it costs.
In Florida, look out for:
- Interior walls under roof trusses or girder trusses. Some interior walls carry roof loads even in a one-story home.
- Concrete block interior walls. Older homes and some newer ones have block walls inside, which may also be part of the structure that resists wind.
- Walls under beams or bearing points from a second floor.

Non-structural walls
Removing a partition that carries no load may be minor work in some jurisdictions, but walls often hide:
- electrical circuits and switches, which need to be relocated or removed properly
- plumbing vents and supply lines
- air conditioning ducts and returns
Each of those has its own permit and licensed trade. Call your building department with your plan before demolition.
What the process looks like
- A contractor or engineer confirms whether the wall is structural.
- For structural walls, an engineer designs the beam, posts and connections.
- The contractor applies for the permit with the drawings.
- Temporary shoring supports the structure while the wall comes out.
- Inspectors check the framing and connections before drywall covers them. See building inspections in Florida.
Who should do it
Structural work needs a licensed general, building or residential contractor (or an owner-builder doing it on their own home with the required permit and design). See general contractor vs. hiring trades. For budgeting a kitchen opening, see our kitchen remodel cost guide and kitchen permit guide.
Frequently asked questions
How do I know if a wall is load-bearing?
Clues include walls running perpendicular to the ceiling joists or trusses, walls under a beam or another wall, and concrete block interior walls. But only a qualified professional can say for sure. Our load-bearing walls guide explains what to look for.
Can I remove a non-load-bearing wall without a permit?
Some building departments treat removing a truly non-structural partition as minor work, but if the wall contains wiring, plumbing or ductwork, moving those needs permits. Ask your building department before you start.
How much does it cost to remove a load-bearing wall?
It depends on the span, what the wall supports and whether it's wood frame or block. Engineering, a beam or header, temporary shoring, patching and permits all add up, and it's usually part of a larger kitchen or living area remodel.
