More space, matched to your home and your local code

Adding on is the most structural work a home can undergo — foundation, framing, roofline, and tie-ins all have to be engineered and permitted correctly. We manage the whole process, from feasibility and design through permits and final finishes.

Additions and accessory dwelling units (ADUs) are handled differently by each jurisdiction — the City of Oviedo, unincorporated Seminole County, and the City of Orlando each set their own rules. We build to what actually applies to your Kissimmee lot.

More space, matched to your home and your local code

Engineering & permits

We coordinate the structural engineering, permitting, and any HOA/ARB review so the addition is legal and lasting.

Kissimmee, Osceola County

What a home addition in Kissimmee involves

We work throughout Kissimmee — from Buenaventura Lakes and Remington to Kissimmee Bay, Mill Run, Tapestry. Kissimmee is the Osceola County seat, a diverse and fast-growing city south of Orlando, and it sits in Osceola County, part of the Greater Orlando area we cover from our base in Oviedo.

Permitting for a Kissimmee home addition goes through City of Kissimmee Building Division. Not every Kissimmee address is inside the city limits — some are unincorporated Osceola County, and that changes which department reviews your plans. We confirm the jurisdiction for your exact address before anything gets filed.

Alongside Kissimmee, we regularly take on work in nearby Osceola County communities including St. Cloud, Celebration.

Every Kissimmee home addition we take on is run by the same licensed general contractor (CGC1539321) that pulls the permit — so there is one point of accountability from the first walkthrough in Buenaventura Lakes or Remington through final inspection with City of Kissimmee Building Division.

Additions & ADUs FAQ

Common questions

It depends on your city or county's zoning, lot size, and setbacks — the rules differ across Oviedo, unincorporated Seminole County, and Orlando. We check what applies to your specific lot before you spend money on design. In Kissimmee, that review goes through City of Kissimmee Building Division, and we build their turnaround into the schedule we give you.
Most room additions run about 3–5 months from permit to finish; second stories and ADUs take longer. Engineering and permitting happen before we break ground, and we give you a schedule up front. For Kissimmee specifically: City of Kissimmee permits inside city limits; unincorporated addresses go through Osceola County.
Yes — additions require structural engineering and permitting, and we coordinate both, plus any HOA or architectural-review approval, as part of the project. We do this work across Kissimmee and the wider Osceola County area from our base in Oviedo.
