About KNU Construction

A veteran-owned, woman-owned, and minority-owned Fort Lauderdale general contractor built around execution — self-performing key trades and holding the schedule from permit to punch list across Florida.

Who We Are

One Licensed Team, One Point of Accountability

KNU Construction is a licensed Florida general contractor, roofing contractor, and plumbing contractor based in Fort Lauderdale, serving commercial, residential, and multifamily projects across the entire state.

Most projects stall in the gaps between trades — the hand-offs where scope gets lost, schedules slip, and no one owns the outcome. KNU Construction is structured to close those gaps. Because we are a licensed general contractor and a licensed roofing and plumbing contractor, we self-perform the trades that most often drive schedule and quality, then directly manage everything else.

We self-perform roofing and plumbing, deliver general contracting and commercial drywall and interior buildouts in-house, and coordinate a vetted subcontractor network for the remaining scopes. The result is a single chain of accountability from the first site walk to the final walkthrough — one contractor responsible for the permit, the budget, the build, and the close-out. As a Broward County general contractor serving all of Florida, that discipline is what we are built to deliver, whether the job is a single tenant improvement or a ground-up multifamily project.

Our Approach

How We Run Every Project

No theatrics, no vague promises — just a repeatable way of working that protects your scope, your schedule, and your budget.

Execution-Focused

We measure ourselves on work completed, not promises made. The plan exists to get the job built right and handed over.

Transparent Estimating

Clear, itemized estimates with a defined scope of work — no vague line items and no surprise change orders.

Permitting Expertise

We coordinate permits, drawings, and inspections with local jurisdictions so the build starts clean and stays compliant.

Schedule Discipline

Milestones are tracked and protected. You know what comes next and when — and we hold ourselves to it.

Quality Control

Ongoing quality checks during construction keep workmanship and code compliance to standard, not to the deadline.

Punch-List Close-Out

We walk the finished project with you, complete the punch list, and close out cleanly — done means done.
