A custom home is not just a design decision. It is a management decision. The right GC should be able to explain cost control, schedule control, communication, insurance, licensing, and how changes are handled before the first shovel hits the ground.
Start with the basics: license, insurance, real business presence
In Florida, verify the contractor's license directly through the state's official portal. You should be able to confirm the license number, profession, business address, and license status.
Also ask for proof of general liability and workers' compensation coverage. If a builder hesitates here, move on.
A professional GC should give you a written contract early
“Do not hire anyone who tells you a contract is unnecessary.”
The contract should clearly state:
- what work is included
- what work is not included
- the payment schedule
- the process for changes
- the expected timeline
- how allowances are handled
- what happens if materials or selections change
Ask how they manage allowances
Allowances are not bad by themselves. They are placeholders. The problem is when they are vague or unrealistically low.
If a contract includes allowances for cabinets, tile, plumbing fixtures, appliances, lighting, or exterior finishes, ask:
- what dollar amount is included
- what quality level that amount realistically buys
- what happens if final selections exceed the allowance
- whether installation, freight, and taxes are included
Ask how communication actually works
Clear communication is not a soft skill here. It is cost control.
- who your point of contact is
- how often you get updates
- how change orders are approved
- how site decisions are documented
- how billing ties to progress
Check references the right way
Do not just ask whether past clients were happy. Ask whether the builder stayed close to budget, explained changes early, kept the site organized, finished punch-list items, and whether the client would hire them again.
That last question usually tells you more than the first four.
Red flags worth taking seriously
- the bid is far lower than the others
- the contract is thin or unclear
- insurance documents are missing
- references are hard to reach
- the builder cannot explain schedule logic
- 'we'll figure it out later' shows up too often
The clean conclusion
“A custom home does not need a flashy salesperson. It needs a disciplined operator.”
