Room Addition Scope Audit for Hoboken, NJ

Reviewed May 26, 2026

Room addition bids are only comparable when the new square footage is defined as a complete conditioned living-space project. Separate foundation, framing, roof tie-in, HVAC, electrical, insulation, windows, doors, finishes, drainage, permits and inspections before comparing prices. Use the $119,835 midpoint as a planning number, then require the written scope below before comparing Hoboken contractor bids.

Scope checks

  • - Addition type: bedroom, family room, primary suite, second story, garage tie-in or bump-out, with new square footage and room use stated.
  • - Shell scope: foundation or slab, framing, roof tie-in, exterior wall finish, windows, doors, insulation, air sealing and weatherproofing.
  • - Systems scope: electrical panel capacity, lighting, outlets, HVAC load, ducts or mini-split, plumbing if a bath or wet bar is included, smoke/CO alarms and energy compliance.
  • - Site and closeout: plot plan, setbacks, drainage or stormwater plan, inspections, final approval, cleanup and written change-order pricing.

Ask before deposit

  • - Is this priced as finished conditioned space, shell-only construction or an addition with bathroom/plumbing?
  • - Who prepares drawings, energy forms, structural calculations and permit submittals?
  • - How are roof tie-in, foundation, HVAC load, electrical panel capacity, stormwater and inspections handled?

Common misses
