Home Addition Cost in Chaska

Additions in the Twin Cities typically run $300–$500+ per square foot all-in, with second-story additions and complex tie-ins at the high end.

Process & Timeline

  1. Design & scope. A design-build firm develops plans, selections, and a fixed scope before construction pricing. Expect several weeks of design for anything beyond a cosmetic refresh.
  2. Permits. Your contractor pulls city permits for plumbing, electrical, and structural work. This is non-negotiable in Chaska.
  3. Construction. Timeline depends on scope; see the FAQ below for typical durations. Good firms give you a milestone schedule and a named project lead.
  4. Punch list & inspection. Final inspections close the permits; a written warranty (1 year workmanship is standard in MN) should back the work.
