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 rules change between each city and the unincorporated parts of Seminole, Orange and Osceola counties. We build to what actually applies to your Greater Orlando lot.

Timeline

How long a home addition takes in Greater Orlando, stage by stage

Typical time: about 3–5 months from permit to finish for a room addition; second stories and ADUs take longer. The stages are the same for every addition we build across Greater Orlando; what changes is the size of the job and the review time at your building department.

  1. Site visit and feasibility — we measure, check the slab, roof, electrical panel and plumbing, and confirm the zoning setbacks and any HOA or architectural review for your lot.
  2. Design — a floor plan and elevations matched to the house, then a written, itemised estimate.
  3. Structural engineering — sealed drawings for the foundation, the roof tie-in and the wind design for your address, plus energy calculations.
  4. Permit review — the set goes to your city or county building department; we answer any review comments, and the written schedule you get with the estimate builds in that turnaround.
  5. Construction — foundation, framing, the roof tie-in and dry-in, then the trades, insulation, drywall and finishes.
  6. Inspections and close-out — every inspection scheduled by us, the permit closed, and a final walkthrough with you.

Planning Ranges

Additions & ADUs in Greater Orlando: what it typically costs

Typical planning ranges for a Greater Orlando addition or ADU. Planning ranges only, not a quote — final pricing depends on size, foundation and site.

ProjectTypical rangeNotes
Room addition$40,000 – $120,000Size, foundation, finishes
Second-story addition$150,000 – $300,000+Structural reinforcement, new stair, roof
ADU / garage conversion$50,000 – $180,000Detached vs. conversion, utilities, kitchen/bath

These are typical planning ranges — not a quote. Every project is priced after we see the space.

What moves the price of a home addition

  • Square footage and layout — the number of rooms, closets and doors.
  • Foundation and site — slab-on-grade or raised floor, soil, drainage and whether the lot is in a mapped flood zone.
  • The roof tie-in — matching tile or shingle, and whether part of the existing roof is redone so the two match.
  • Plumbing — a bathroom or kitchenette adds the most, and septic capacity matters on homes that are not on sewer.
  • Finishes, windows and doors — rated for the design wind pressure at your address, matched to the house or upgraded.

Additions & ADUs FAQ

Common questions

It depends on your city or county's zoning, lot size, and setbacks — the rules differ from one jurisdiction to the next across Seminole, Orange and Osceola counties. We check what applies to your specific lot before you spend money on design.
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.
Yes — additions require structural engineering and permitting, and we coordinate both, plus any HOA or architectural-review approval, as part of the project.
An addition expands your existing home; an ADU is a separate living unit with its own kitchen and bath, whether detached or a garage conversion. They're permitted differently — we'll explain which fits your goal.
Our October 2026 planning ranges across Greater Orlando: room addition $40,000 – $120,000; second-story addition $150,000 – $300,000+; ADU or garage conversion $50,000 – $180,000. Size, the foundation, the roof tie-in and plumbing move the number most, and every project is priced after a site visit. See the room addition cost guide and home additions in Orlando.
Yes, always. An addition is structural work, so Florida's $7,500 permit exemption does not apply; it needs a building permit with engineered drawings plus electrical, plumbing and mechanical permits from the office that covers your address — the city inside city limits, the county elsewhere. We pull the permit and schedule the inspections. Details: home addition permits in Orlando & Seminole County.
Usually. Under Florida's Save Our Homes rules, additions and improvements are assessed at just value when they are added, so the new space is taxed at its value even though the yearly increase on the existing homestead stays capped. The county property appraiser sets the figure; the sources are on our FAQ.
For a ground-floor addition, usually yes: the new rooms go up outside the existing walls and the opening into the house is cut late, so most of the home stays closed and usable. A second story has a roof-off and dry-in stage that can make parts of the house unusable for a period; we plan that sequence with you before work starts.
Not usually. As a design-build contractor we produce the plans, and a Florida-licensed engineer seals the structural drawings the permit requires. A separate architect makes sense for a complex or highly custom house, and we can price and build from an architect's drawings if you already have them. Compare the two routes in design-build vs architect.
Any month — we build year-round. The Atlantic hurricane season runs June 1 to November 30 and summer brings afternoon rain, so the stages that open the house (the roof tie-in on a room addition, the roof-off stage on a second story) are scheduled with that in mind. Engineering and permit review take weeks either way, so starting the paperwork in summer often means building in the drier months.
Our Greater Orlando remodeling FAQ covers ADU rules, property taxes and addition costs, with sources for every Florida rule it cites.
