Why junior adu (jadu) × Las Vegas produces this band

A junior adu (jadu) scope for a adu in Las Vegas 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, Las Vegas runs 2% below the national median — so the junior adu (jadu) band comes in 65% below the mid-range, then scales 2% below the national median on top of that. Permit timelines for residential work in Las Vegas typically run 3-8 weeks, which is the window you plan your design and decision sequence against. This page gives you the actual 2026 Las Vegas 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

·Efficiency kitchen with limited plumbing (no garbage disposal in many jurisdictions)
·Independent entrance cut into an exterior wall
·Owner-occupancy covenant recording
·Shared utility metering (no new service drop)

What makes Las Vegas different

Labor — Gaming + hospitality remodel cycles create periodic labor-supply tightness — residential remodel competes with hotel refurbishment.
Labor — Summer 110°F+ heat shifts exterior trades to pre-dawn shifts.
Labor — Non-union residential market with competitive rates outside of Strip-corridor peak cycles.
Material — Desert-climate materials (reflective roofing, drip irrigation integration) are a small premium.
Material — Regional supply from LA and Phoenix distribution hubs — lead times typically short.

Las Vegas rules that affect this scope

Clark County Department of Building & Fire Prevention handles permits for unincorporated areas (most of the Strip + suburbs).
City of Las Vegas handles residential within city limits — separate process from Clark County.
Henderson and North Las Vegas each have their own building departments with distinct amendments.
Nevada State Contractors Board (NSCB) licensing required for any work over $1,000 — verify license class matches scope.
