It's your responsibility to call your local building department and find out whether sealed plans are required. If they are, we coordinate with a licensed structural engineer, who reviews the calculations in our plans, makes any adjustments necessary, and seals them. The engineer's fee is passed through at cost: commonly $1,000–$3,000, and from about $500 to $5,000 depending on the home. Plus our $150 coordination fee.

  • Architect-drawn custom plans commonly run $10,000–$20,000 once revisions are included. That's what we see as general contractors; it depends on the size of the home and how custom it is.
  • Our price: $1,495 up to 1,800 living sq ft, plus $0.75 (Standard) to $1.25 (Complex) per sq ft over 1,800, with three rounds of revisions included. The table uses the Standard price. Savings = the typical architect-drawn set minus our price.
  • Sealed plans, only if your building department requires them: a licensed structural engineer reviews, adjusts and seals our plans. Their fee is passed through at cost, commonly $1,000–$3,000, and from about $500 to $5,000 depending on the home, plus our $150 coordination fee. If you need one, subtract it from the savings.
  • Savings are estimates, not quotes or a promise. Your costs will vary.
