How Much Does an ADU Permit Cost in Orlando?
Budget $2,000–$4,000 for the Orlando permit itself (project-based), issued by the Permitting Services Division — but treat that as the entry fee, not the total. ADUs are full dwelling units, so the permit stack usually includes building, electrical, plumbing, and mechanical trade permits, plus plan review. One local note: building fees follow new construction rates ($26 for first $1k + $3/add'l $1k) plus impact fees. Get an itemized fee estimate from the department before finalizing your budget; the spread between a simple conversion and a new detached build is wide.
ADU Size Limits and Zoning Rules in Orlando
Before drawing plans, check the two gates that sink most ADU projects: size and zoning. Size ceilings vary by lot and ADU type (attached, detached, or conversion), so confirm your specific configuration. Setbacks, height limits, and utility connections layer on top of those rules. The Permitting Services Division can confirm what your specific lot allows — worth doing before you pay for architectural drawings rather than after.
