What's included

  • Feasibility, setback and lot-coverage review on your parcel
  • Architectural plans and structural engineering
  • Permitting with Clark County, City of Las Vegas, Henderson or North Las Vegas
  • Foundation, framing, roofing and exterior to match the existing house
  • Full MEP — electrical, plumbing, HVAC tied into existing systems
  • Interior finish — drywall, flooring, millwork, paint — to match adjacent rooms
Typical timeline
Most Las Vegas home additions run 4–7 months total — 8–14 weeks of design and plan check followed by 12–22 weeks on-site, depending on whether it's a single-room ground-floor addition or a full second story.
Investment
Home additions in the Las Vegas Valley typically run $250–$550 per square foot all-in, with most projects landing between $120,000 and $600,000+ depending on size, foundation type, second-story tie-ins and finish level.
Materials we specify
Exterior stucco, window line and roof profile matched to the existing house. Interior finishes — flooring, trim, millwork, paint — carried through from the original rooms so the addition reads as continuous, not bolted on.
