Home Additions in Kissimmee, FL
Designed in 3D, permitted with the right Osceola County or city office, and built by a licensed Florida general contractor that also holds its own plumbing license.

Home addition projects in Kissimmee
In Kissimmee, additions are mostly about fitting more people into the house. Families in 1980s and 1990s subdivisions off Pleasant Hill Road and in Buenaventura Lakes add a bedroom, a primary suite or a space for a parent moving in, and some convert the garage into living area. Vacation home owners near US 192 ask about adding a bedroom and bathroom so the home can sleep more guests. Either way, the addition has to read as part of the original block and stucco house, with a matching roofline and the same finished floor height.
What changes for a home addition in Kissimmee
Before design, we confirm whether the parcel is inside city limits, where the City of Kissimmee Development Services Building Division reviews the addition, or in unincorporated Osceola County, where the Osceola County Building Office does. Setbacks and lot coverage come next, since many subdivision lots here are tightly spaced. Bellalago and the resort communities near US 192 usually require architectural approval for exterior changes before the permit, and some restrict garage conversions. New footings are doweled into the existing slab, the soil gets termite pretreatment, and the roof tie-in is flashed for summer storms.
Local details we plan around
- Check city limits first: many Kissimmee addresses are unincorporated Osceola County, which changes the permit office and inspection scheduling.
- Vacation rental owners often need the work scheduled between bookings, with a property manager handling access and a firm finish date for the next guest.
- Rental homes take heavy wear, so we steer toward porcelain tile, quartz, solid-surface or tile showers and finishes that clean up fast between stays.
- Older homes near Lake Toho and downtown may hide older plumbing and electrical that a remodel has to bring up to current code.

Scope
What the work includes
Feasibility and zoning check
Before design, we review your lot survey, setbacks, lot coverage limits and HOA rules to confirm how much you can build and where it can go.
Design and 3D rendering
We design the addition to match the roofline, windows and finishes of the existing house, and show it in 3D so you can see the result before engineering.
Engineering and permit drawings
Licensed design professionals prepare structural plans and energy calculations. We submit the permit package and respond to any reviewer comments.
Foundation and slab
New footings and slab, tied into the existing foundation with doweled reinforcing, with termite pretreatment and a vapor barrier under the new concrete.
Framing or block walls and roof tie-in
Concrete block or wood framing to match the engineered plans, new trusses or rafters, and a roof tie-in that sheds water and matches the existing roofing.
Plumbing, electrical and HVAC
New bathrooms and kitchenettes plumbed under our own license, new circuits and panel review, and air conditioning sized for the added square footage.

"It is a pleasure to recommend Prime Construction / Kitchens for any of your home remodeling needs. Prime Construction helped me diagnose a problem with a wall in my garage related to a window leak. Prime Construction shared with me how I could address the issue myself and saved me the cost of a dispatch by their team. They were only concerned with helping me resolve my issue. I give my full recommendation to Prime Construction. Thank you"

FAQ
Home Additions in Kissimmee: questions
Do not see your question? Call us or send the estimate form and we will answer it on the phone.
Can I add a bedroom to my Kissimmee vacation home so it sleeps more guests?
Often, if the lot has room within the setbacks and the association approves the exterior. A bedroom meant for guests usually needs its own bathroom and air conditioning sized for the new space, and the community may have parking or occupancy rules to check. We review your survey, the association rules and the permit path with the city or Osceola County before any design work.
Is my Kissimmee address in the city or in Osceola County?
It depends on the parcel, not the mailing address. Many homes with Kissimmee addresses, including Buenaventura Lakes, Bellalago and most resort communities along US 192, are in unincorporated Osceola County. The City of Kissimmee has a Check City Limits lookup on its website, and we confirm jurisdiction before we design so the permit goes to the right office.
Can you remodel my Kissimmee vacation rental while I live out of state?
Yes. We can measure with your property manager present, review the 3D design and material choices with you by video and email, and coordinate access through the manager during the work. We schedule around your booking calendar where possible and finish with a walk-through, by video if you cannot be there, before the next guests arrive.
How long does a home addition take in Orlando?
Most room additions take about 3 to 5 months of construction once permits are issued. Design, engineering, HOA review and permitting usually add 2 to 4 months before work starts. Garage conversions are typically faster because the roof and walls already exist. We give you a written schedule before construction and keep you updated as each phase passes inspection.
Do I need a permit for a room addition in Florida?
Yes. Any addition that adds space, changes structure or adds plumbing and electrical requires a building permit, engineered drawings and inspections. The permit is issued by your city building department if you are inside city limits, or by the county in unincorporated areas. As a licensed general contractor, we prepare and submit the permit package.
Can I build an in-law suite or ADU on my property?
It depends on your local zoning. An attached in-law suite with a bedroom and bathroom is usually allowed where additions are allowed. A separate unit with its own kitchen and entrance is treated as an accessory dwelling unit in many places, and rules on size, parking and occupancy vary by city and county. We check the rules for your parcel first.
