Quick Answers About Orlando, FL ADUs
Market Context
Orlando has a median home value of $298,000. Adding an ADU typically increases that by 25% — approximately $74,500 in added equity. A 1-bedroom ADU in Orlando rents for approximately $1,490/month in the Orange County rental market , yielding a 6.8% cap rate on the investment. Occupancy averages 91% in this market.
Top Orlando neighborhoods for ADU investment include College Park, Delaney Park, Thornton Park, Lake Eola Heights, Audubon Park. Close-in single-family neighborhood near downtown with steady rental demand and many buildable lots. Immediate proximity to downtown jobs and amenities makes it attractive for rental ADUs.
Permit Process
Permit applications are reviewed by the Permitting Services Division , with a plan check timeline of approximately 6 weeks. Permit fees in Orlando range from $2,500 to $10,000 depending on project scope. Design review: Yes - in historic districts only (Certificate of Appropriateness required); Appearance Review may apply in Traditional City overlay or for corner lots
Orange County's Permitting Services Division will kick back your ADU application if your lot falls under the Wekiva River Protection Area or falls within certain drainage basins tied to the Econlockhatchee River — triggering an extra environmental review that can tack on 3-4 weeks before plan review even starts. Older Orlando neighborhoods like College Park or Delaney Park also frequently have undersized water laterals from the 1950s, so the City's utility department may require you to upsize your service line at your own cost before they'll sign off on a new meter for the ADU. Since STRs are allowed county-wide, don't forget Orange County requires a separate STR registration and tax certificate — a step people often skip and get fined for after their ADU is already rented out.
"In my experience with Orlando permitting, that 6-week timeline and $200/sqft figure are state-level estimates, not gospel—I'd get at least two local contractor quotes and call the Permitting Services Division directly before penciling in a start date. With HOA presence at 78% in this market, I've also seen HOA architectural review add weeks that never show up in a city permit timeline, even when the county process itself moves quickly."

Property Eligibility
Is My Orlando, FL Property Eligible for an ADU?
Orlando homeowners are governed by local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Orlando under local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval. No owner-occupancy requirement in Orlando — you can rent both units as investment properties. Review process and timelines are set by local ordinance — confirm the current process with the Permitting Services Division before designing.
Multi-Family Property
Additional ADUs on multi-family and duplex lots may qualify under local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval — the exact number and type allowed depends on Orlando's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 78% of Orlando homes are in an HOA. Florida Statute §720.3035 limits HOA control over certain interior changes but does not preempt CC&Rs that ban ADUs outright — Florida HOAs generally retain the ability to restrict ADUs through their covenants. Our drawings include HOA submission formatting.
Historic Districts
Yes - in historic districts only (Certificate of Appropriateness required); Appearance Review may apply in Traditional City overlay or for corner lots
Always verify eligibility with Permitting Services Division before designing.

Orlando ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Orlando construction costs, median rental rates, and property value uplift data. Adjust the inputs to model your specific project.
Your Project
Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 25% uplift (regional ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.

Orlando ADU Market at a Glance
Local Zoning Rules
2026 Orlando ADU Rules
Orlando's 2026 ADU ordinance caps new units at 1,000 sq ft and 35 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run 5 ft side and 5 ft rear, close to the regional baseline. Because of FL's statewide wind-load provisions (Florida Building Code wind design / High-Velocity Hurricane Zone rules), structural drawings for a detached ADU here need a licensed engineer's stamp — architectural sheets for a code-compliant unit under the size cap generally don't.
Permit fees run $2,500–$10,000 — in line with what most homeowners budget for permitting, and plan check takes about 6 weeks at Permitting Services Division. Submit directly to the department online — link below.
| Regulation | Orlando Allowance |
|---|---|
| Max ADU Size | 1,000 sq ft |
| Max Height | 35 ft |
| Side Setback | 5 ft |
| Rear Setback | 5 ft |

We turn your backyard into a rental unit. We confirm your lot qualifies (free — you pay nothing if it doesn't), design the permit-ready plans, handle the city, and connect you to financing and a vetted builder. One flat fee — about what an architect charges just to start. Yours would rent around $1,490/mo.
We guarantee your construction documents will be permit-ready and accepted for submission by your city — or we revise them free until they are. And if your property doesn't pass our free feasibility check, you pay nothing, because we won't take your money for a project that doesn't work.
