Most of what gets written about Orange County ADUs covers the zoning rules: what you’re allowed to build. Ready Set Orange is different. It’s the county handing you a design for free, so you’re not paying an architect to draw the same 600-square-foot box everyone else in unincorporated Orange County is also building.
What you need before you start: a homesteaded primary residence in unincorporated Orange County, and a sense of whether you want a detached ADU in the 531–708 sq ft range the program’s plans cover.
Step 1: Confirm you qualify
Ready Set Orange applies only to unincorporated Orange County. For the ADU track, your primary residence on the parcel has to be homesteaded. Long-term rental of the finished ADU is fine; short-term rental is prohibited under the program, with an exception carved out for R-3 zoning. If your property sits inside Orlando, Winter Park, Apopka, Ocoee, Winter Garden, Maitland, or Belle Isle, you’re inside a city, and this county program doesn’t apply to you; check that city’s own housing programs instead.
Step 2: Pick one of the four ADU plans
The county offers four pre-designed, code-reviewed ADU floor plans running 531 to 708 sq ft. A separate track of the same program offers four single-family starter home plans at 1,150–1,483 sq ft, aimed at a different kind of project entirely. For an ADU, you’re choosing among the four smaller plans. The county’s program page has the layouts; compare footprint and room arrangement against your lot before you request anything.
Step 3: Request the plans
Submission happens through the Ready Set Orange program page. The plans are provided at no cost to qualifying property owners; that’s the core of what the program offers.
Step 4: Decide on the affordability certification
Ready Set Orange has an optional layer on top of the base program: Certified Affordable/Attainable Housing status. Qualifying gets you expedited plan review and a water/wastewater fee discount (25% at the Affordable tier), with potential impact-fee reductions on top. It comes with its own eligibility criteria, separate from ADU eligibility itself, so it’s worth a call to the Planning Division to find out whether your project’s income parameters or rent structure would actually qualify before you count on the discount.
Step 5: Confirm your lot against the underlying zoning rules
The pre-approved plans are built to meet Chapter 38’s ADU size caps, but where the structure can actually sit on your lot still depends on your zoning district’s setback requirements. Check your specific lot against the rules on our Orange County page before you settle on a plan orientation, especially if your lot is narrow or has easements running along the rear or side.
Step 6: Submit through FastTrack
Orange County runs permitting through FastTrack. The county hasn’t published a specific reduced timeline figure for Ready Set Orange applications versus a fully custom design, but the mechanism is real: using a pre-reviewed plan means your submission skips the portion of plan review a from-scratch design would otherwise go through.
What this doesn’t cover
This program addresses design cost, not permit or impact fees; both still apply to a Ready Set Orange ADU the same as any other. It also doesn’t cover general zoning eligibility (lot size, HOA covenants, utility capacity); start with our zoning-check guide for that. And it’s specific to unincorporated Orange County; there’s no equivalent program covered here for the incorporated cities within the county.
Quick-reference checklist
| Step | Check | Where | Watch for |
|---|---|---|---|
| 1 | Unincorporated Orange County + homesteaded primary residence | Property Appraiser + your homestead exemption status | City parcels don't qualify for this county program |
| 2 | Pick an ADU plan (531–708 sq ft) | Ready Set Orange program page | Four plans only; not custom |
| 3 | Request plans (free) | Same program page | No cost for the plan itself |
| 4 | Consider affordability certification | Planning Division | Separate eligibility criteria from base ADU program |
| 5 | Hire licensed architect/engineer to finalize | Your own contractor search | Still required even with a pre-approved plan |
| 6 | Confirm lot against zoning setbacks | County page, Chapter 38 | Plan meets size caps; your lot still governs placement |
| 7 | Submit | fasttrack.ocfl.net | No county-published timeline reduction figure; skipping full plan review is the mechanism |
