How much do residential MEP plans cost?
Residential MEP plan pricing at MEP Plans USA is flat-rate, based on your home's conditioned square footage and how many disciplines you need. A single-discipline set starts at $1,495, a two-discipline package starts at $2,495, and a full mechanical, electrical, and plumbing package starts at $3,495. There is no sales tax and there are no hidden fees.

Pricing reflects design scope, and engineering stamp requirements differ by city or county — when a stamp is needed, we provide a custom quote rather than folding it into the flat rate. Because the base price is tied to size and discipline count, you can estimate your total before submitting anything, then layer on only the add-ons your project actually needs. This keeps budgeting predictable and avoids the surprise line items that sometimes appear with hourly engineering work. Requirements vary by jurisdiction — verify with your local building department, since a city-specific submittal item could affect your final scope. For a side-by-side comparison of every tier and discipline combination see our pricing page, or place your order to lock in your flat rate today.
