What to Look for in an Orlando ADU Contractor
Florida DBPR license and Orange County experience
Any contractor you hire must hold a current Florida Department of Business and Professional Regulation (DBPR) Certified General Contractor or Residential Contractor license. More important: verify they have pulled permits specifically with Orange County or the City of Orlando — not just in other Florida jurisdictions. ADU permitting requirements differ significantly by city.
Verifiable ADU permit history
Ask for the addresses of 3–5 ADUs they have completed in Orange County within the last 18 months. Look up the permit status on Orange County's public permit portal to confirm they were actually permitted and received a Certificate of Occupancy. A builder who cannot provide this is likely not as experienced as they claim.
Fixed-price vs. cost-plus contracts
In Florida's volatile construction market, fixed-price contracts protect you from material cost increases mid-project. Cost-plus contracts (materials + labor markup) can balloon 20–40% above initial estimates. TEK Construction Group and most dedicated ADU builders offer fixed-price contracts. Get this in writing before signing.
Knowledge of City vs. County jurisdiction
Many Orlando addresses fall under Orange County jurisdiction, not the City of Orlando — and the two have different ADU rules, setback requirements, and permit processes. A builder who doesn't immediately know which jurisdiction your parcel falls under has not done many ADUs in your area. This is a fast, reliable screening question.

City of Orlando and Orange County ADU eligibility depends on your specific parcel. Takes 30 seconds, no sign-up required.

Can any general contractor build an ADU in Orlando?
Any Florida-licensed general contractor can technically pull an ADU permit. But Orlando ADU permitting has specific requirements that an experienced specialist navigates faster. Ask any GC for their ADU permit history in Orange County specifically — not just Florida generally. That's the fastest way to assess real ADU experience.
