Key takeaways
- General contractors usually charge either a percentage of the project (often 10 to 20 percent) or a fixed price that already includes their fee.
- That fee pays for managing permits, subcontractors, scheduling, materials, and accountability, not just labor.
- Total project cost depends far more on scope and finishes than on the GC’s markup.
- The cheapest bid is rarely the best value. Missing scope and cut corners cost more later.
One of the first questions homeowners ask is what a general contractor actually costs in Jacksonville. The honest answer is that it depends on how the contractor charges and on the size of your project, but here’s a clear breakdown so you know what’s normal and what you’re paying for.
How do general contractors charge?
There are two common models. With cost-plus, you pay the actual cost of materials and labor plus the contractor’s fee, usually a percentage of the project, often in the range of 10 to 20 percent. With a fixed-price (or lump-sum) contract, the contractor quotes one total number that already includes their fee, materials, and labor. Fixed-price gives you more budget certainty; cost-plus can be more transparent on a project where the scope may shift. Either way, the contractor’s fee covers project management, not just hammering nails.
What does the contractor’s fee actually pay for?
It’s easy to look at a GC’s markup and wonder what you’re getting. You’re paying for someone to pull and manage permits, line up and supervise licensed subcontractors, order and coordinate materials, keep the job on schedule, handle inspections, and take responsibility if something goes wrong. On any project with multiple trades, that coordination is what keeps costs from spiraling.
Typical Jacksonville project cost ranges
These are broad ranges to set expectations. Your actual cost depends on size, finishes, and condition of the existing structure, so get a written estimate.

What drives the price up or down?
- Scope and size – more square footage and more trades cost more.
- Finishes – the gap between builder-grade and luxury materials is huge.
- Structural and hidden issues – older homes often reveal surprises once walls open up.
- Permits and code upgrades – bringing older work up to current Florida code adds cost.
- Design complexity – moving plumbing, electrical, or load-bearing walls adds labor.
How to get the best value (not just the lowest price)
Get three written estimates for the same scope, and don’t automatically take the cheapest. A lowball bid usually means missing scope, lower-grade materials, or change orders waiting to happen. Look for a licensed, insured contractor who gives you a clear written scope and stands behind the work.

Frequently asked questions
What percentage does a general contractor charge in Florida?
Many general contractors charge a fee in the range of 10 to 20 percent of the total project cost, though fixed-price contracts fold that fee into one quoted number. The exact percentage varies with project size, complexity, and risk.
Is it cheaper to be my own general contractor?
It can look cheaper on paper, but acting as your own GC means you’re responsible for permits, scheduling, hiring and managing subs, inspections, and any mistakes. For most homeowners, the time, risk, and lack of trade relationships outweigh the savings, especially on larger projects.
Why is one contractor’s bid so much lower than the others?
Usually because it leaves something out: scope, code-required work, permit costs, or quality materials. It can also signal an unlicensed or inexperienced contractor. Compare bids line by line for the same scope before deciding.
Does the contractor’s fee include permits?
It should be spelled out in the contract. Many GCs include permitting in their scope and price, but always confirm who pulls and pays for permits before you sign.
