Frequently Asked Questions About Home Additions
The cost depends on the type of addition, square footage, and finish level. A basic room addition in the Orlando area typically starts around $80,000 to $100,000. A sunroom or enclosed lanai can run $30,000 to $80,000. Second-story additions and ADUs are larger projects and often run $150,000 to $300,000 or more. TEK provides free, detailed estimates so you know exactly what you are getting before any work begins.
Yes. All structural additions, including room additions, second stories, sunrooms, and ADUs, require permits from your county or city building department. TEK handles the entire permitting process, including architectural drawings, structural plans, and inspections. We work regularly with permitting offices in Orange, Osceola, and Seminole counties.
Timeline varies based on scope. A single-room addition typically takes 3 to 5 months from permit approval to final walkthrough. A second-story addition can take 5 to 8 months. ADUs and full home expansions run 6 to 12 months depending on complexity and permitting timelines in your area. TEK gives you a construction schedule upfront and communicates with you every step of the way.
Matching is a priority for us. Our team designs additions to blend with your existing roofline, siding, windows, and interior finishes. You will see design renderings before construction begins so there are no surprises. We work with architects and designers to make sure the addition looks like it was always part of the house.
In most cases, yes. Room additions, sunrooms, and lanai builds are typically isolated from your main living area so you can continue using your home. For second-story additions or large whole-home expansions, there may be periods where certain areas are inaccessible. TEK plans the construction schedule with your comfort in mind and will be upfront about any disruption.
TEK serves homeowners across Central Florida including Orlando, St. Cloud, Winter Park, Lake Nona, Kissimmee, Windermere, Winter Garden, and Narcoossee. If you are unsure whether we cover your area, give us a call or visit our service areas page.
Yes. We partner with GreenSky to offer financing options for home additions and remodeling projects. This allows you to move forward with the project you want without having to wait. Ask about financing options during your free consultation.
A home addition expands your main home's footprint and remains part of the primary structure, sharing walls, utilities, and a single address. An ADU (accessory dwelling unit) is a separate or semi-separate dwelling on the same lot, with its own entrance and often its own kitchen and bathroom. ADUs can be rented out independently, while a home addition typically cannot. TEK builds both, and we can help you figure out which option fits your goals.
