Red Flags When Hiring a Contractor in Miami: A Builder Tells You What to Walk Away From

Most bad construction outcomes in Miami were predictable at the first meeting. The owner saw the signal — a bid dramatically under the others, a contractor vague about who pulls the permit, a request for half the money up front — and talked themselves past it because the schedule was attractive or the price was. This article is the list we'd hand a friend: the red flags when hiring a contractor in Miami, ranked roughly by how expensive they get.

We're Metro Design-Build, a licensed and insured Florida general contractor in Miami — three generations of building here, from Joseph Alter, who invented the Murphy bed, to Herman Alter's South Beach shop, to David Eyal Alter, who earned his GC license at 19 and holds a broker's license as well. We compete against every type of firm described below, so read this as informed bias and verify everything independently.

Is the contractor actually licensed — and is it their license?

The first check is obvious; the failure mode is not. Almost nobody in this market hires a contractor with no license at all. What happens instead is license borrowing: the person you're dealing with operates under a qualifier — a licensed individual who lends their number to a company they don't actually run. The license checks out on Florida's DBPR site, so the owner stops looking.

Dig one layer deeper. Ask who the qualifying agent is and whether that person will be involved in your project. Ask how long the license has been attached to this specific company. A license that hopped between three LLCs in five years is telling you something. Then verify insurance directly — call the carrier, don't accept a PDF — because a certificate of insurance is trivially easy to doctor and worthless if the policy lapsed. General liability and workers' compensation both, and if the contractor says their subs "carry their own comp," ask for those certificates too. In Florida, an uninsured worker hurt on your property becomes your problem.

Why is one bid so much lower than the others?

The lowball bid is the most seductive red flag because it arrives dressed as good news. In high-end remodeling, when one number comes in 25–40% under the field, one of three things is true: the contractor missed scope, the contractor plans to make it back on change orders, or the contractor is pricing to win cash flow they need to finish someone else's job. All three end badly for you.

The tell is in the exclusions page, not the price page. A tight bid says what's not included — allowances stated per item, structural unknowns flagged, permit fees and impact windows called out as Miami-Dade NOA-approved products with a real line item. A vague bid keeps everything soft so it can all be renegotiated later. Related flag: a contractor who resists a detailed scope because "we'll figure it out as we go." That sentence has funded more litigation than any other in this industry. It's also the core argument for the design-build model — when design and construction sit under one contract, the price is built from real drawings, not from a guess that gets corrected at your expense.

What do the payment terms tell me?

Florida law caps what a contractor can take up front before doing work under certain conditions, but the practical rule is simpler: money should follow work, never lead it by much. A request for 40–50% at signing is a contractor financing yesterday's project with your deposit. Reasonable structure looks like a modest mobilization payment, then draws tied to completed milestones you can walk and verify — demolition done, rough-in inspected, cabinetry set.

Two related flags. First, pressure to pay in cash or to skip a written contract "to save you the tax" — that contractor is showing you exactly how they'll treat your paperwork later. Second, a contractor who won't provide lien releases from subcontractors and suppliers with each draw. Under Florida's construction lien law, an unpaid sub can lien your home even if you paid the GC in full. Releases are how you close that door, and a professional firm produces them without being asked.

Who is pulling the permit — and why does the answer matter so much here?

If a contractor suggests you pull an owner-builder permit, end the meeting. An owner-builder permit shifts liability from them to you — it's the move of someone who can't permit the work under their own license or doesn't want the inspection record attached to their name. Equally disqualifying: "we don't really need a permit for this." In Miami-Dade, the permit process is genuinely demanding, and unpermitted work surfaces at the worst possible time: at sale, at refinance, or at an insurance claim after a storm.

This is doubly true for condo renovations, where a second approval layer exists: the association. A contractor unfamiliar with condo board requirements, elevator protection, insurance minimums naming the association, and working-hour restrictions will burn weeks learning them on your dime. Ask directly how many condo projects they've completed in buildings like yours. Combining two units — as we did at the Joy Fishman Residence, two condos merged into one 3,000-square-foot home — involves structural review and approvals that a house remodeler has simply never navigated.

Can they show me finished work and the people who did it?

A portfolio of renderings is not a portfolio. Ask for completed, comparable projects and the ability to speak with those owners — not the two hand-picked references every contractor keeps warm, but recent clients of your project's size. A firm working at the level of a luxury home builder should offer this before you ask; we point people to work like the Stern Residence and let the owners talk.

Then ask who actually performs the work. A GC with no employees is a broker — every trade is subcontracted, quality control is a phone call, and warranty service depends on subs who have no open invoice with you. It's a legitimate business model, but you should know that's what you're buying. We keep 30+ professionals in-house, including our own millwork shop, because self-performance is the only quality control that doesn't rely on someone else's calendar. Whichever firm you choose, ask the question and listen for a straight answer.

The last flag is the quietest: a contractor who agrees with everything. Real builders push back — on the schedule fantasy, on the detail that won't survive salt air, on the allowance that's too thin for the finish level you want. If nobody in the interview told you something you didn't want to hear, keep interviewing. Our published process exists so clients can see the disagreements coming before they're change orders.

What is the biggest red flag when hiring a contractor in Miami?

Licensing and insurance problems, because they poison everything downstream. A contractor operating on a borrowed qualifier or lapsed insurance leaves you with no state recourse, no coverage for injuries on your property, and work that may be unpermittable. Verify the license on DBPR, confirm the qualifier's role, and validate insurance with the carrier directly.

How much deposit should a contractor ask for in Florida?

Money should track work. A modest mobilization payment followed by milestone-based draws is standard for a well-capitalized firm; 40–50% up front is a contractor using your deposit to finish someone else's project. Pair every draw with signed lien releases from subs and suppliers — Florida's lien law lets an unpaid sub lien your property even after you've paid the GC.

Is it a red flag if a contractor says I don't need a permit?

Yes — walk away. Nearly all structural, electrical, plumbing, mechanical, and window work in Miami-Dade requires a permit, and impact openings must use Miami-Dade NOA-approved products. Unpermitted work surfaces at sale, refinance, or an insurance claim, and the cost of legalizing it after the fact routinely exceeds doing it right the first time.
