Why junior adu (jadu) × Tampa produces this band

A junior adu (jadu) scope for a adu in Tampa combines two price levers: scope and metro labor rates. JADUs carve a ≤500 SF unit out of the existing primary structure with an efficiency kitchen (no range, induction cooktop allowed) and a shared or private bath. Cheapest ADU class when the jurisdiction recognizes it. Against the national median remodel labor rate, Tampa runs 5% below the national median — so the junior adu (jadu) band comes in 65% below the mid-range, then scales 5% below the national median on top of that. Permit timelines for residential work in Tampa typically run 4-10 weeks, which is the window you plan your design and decision sequence against. This page gives you the actual 2026 Tampa bands for this exact combination, plus the three cost drivers Baily asks about first when scoping the project live.

What drives cost for a junior adu (jadu) scope

·Independent entrance cut into an exterior wall
·Owner-occupancy covenant recording
·Shared utility metering (no new service drop)

What makes Tampa different

Labor — HVHZ-adjacent — Tampa Bay code is Florida Building Code but not HVHZ; impact windows are optional (and insurance-incentivized) rather than required.
Labor — Storm-season labor cycles similar to Miami but lower intensity.
Labor — Retiree-homeowner demand drives steady remodel pipeline year-round.
Material — Corrosion-resistant hardware recommended for coastal Pinellas and Hillsborough parcels.
Material — Terracotta roof tile (common in mid-century Tampa Bay) restoration adds specialty material premium.

Tampa rules that affect this scope

City of Tampa Construction Services Division issues permits — 4-10 week turnaround standard.
Hillsborough and Pinellas Counties have separate permit processes for unincorporated areas — check jurisdiction before scoping.
Florida Building Code 2023 wind design: 140 mph ultimate design wind speed in most Tampa Bay zones.
Flood-zone VE and AE parcels (coastal + riverine) trigger elevation and utility-placement requirements.
