ADU — Attached ADU Cost in Orlando, 2026

Why attached adu × Orlando produces this band

A attached adu scope for a adu in Orlando combines two price levers: scope and metro labor rates. Attached ADUs share a wall with the primary house. Needs its own entrance, fire-rated separation, and (in most jurisdictions) independent utility metering — but shares the site's foundation-extension cost. Against the national median remodel labor rate, Orlando runs 10% below the national median — so the attached adu band comes in 5% below the mid-range, then scales 10% below the national median on top of that. Permit timelines for residential work in Orlando typically run 4-10 weeks, which is the window you plan your design and decision sequence against. This page gives you the actual 2026 Orlando bands for this exact combination, plus the three cost drivers Baily asks about first when scoping the project live.

What drives cost for a attached adu scope

• ·Fire-rated wall assembly (typically 1-hour, sometimes 2-hour)
• ·Independent utility service drops
• ·Shared-wall sound isolation (STC 50+)
• ·Grading and drainage on the new footprint

What makes Orlando different

• Labor — Inland location keeps labor away from HVHZ-only restrictions — broader trade pool.
• Labor — Tourism-industry remodel cycle drives steady demand in Kissimmee + Lake Buena Vista.
• Labor — Retiree + second-home market in Winter Park and Baldwin Park produces consistent premium-finish work.
• Material — Central Florida material distribution is served by Tampa and Jacksonville ports — competitive pricing.
• Material — Termite-resistant construction (pressure-treated, borate-treated) is a region-specific material cost.

Orlando rules that affect this scope

• City of Orlando Permitting Services runs residential plan review in 4-10 weeks.
• Orange and Osceola County jurisdictions handle unincorporated parcels — different inspection schedules than City.
• Florida Building Code wind zone is inland (140 mph) — no HVHZ impact-window requirement.
• Florida Energy Conservation Code requires HVAC sizing calcs and envelope verification on all remodels touching conditioned space.

Questions LA homeowners actually ask

• What is the 2026 cost range for a attached adu scope adu in Orlando?

  $153,900-$324,900, with the median landing near $239,400. The range reflects finish tier and layout complexity within the attached adu scope; the Orlando labor multiplier of 0.90× vs national median is baked in.

• How long does a attached adu scope adu take in Orlando?

  22-32 weeks of on-site construction for the attached adu scope, plus 4-10 weeks of permit review in Orlando if the scope requires a permit. Cosmetic-only refreshes often skip permits; anything touching plumbing, electrical, or structural does not.

• What is the single biggest budget-overrun risk for this scope?

  Utility separation surprises — some markets require a new electrical service drop from the street, not just a sub-panel. Utility-company coordination adds 6-10 weeks and $8-14K.
