Advanced House Plans draws to Omaha, Nebraska building codes, so some changes may be needed to meet your local standards, and areas prone to earthquakes or hurricanes may require review by a local engineer. Plans are not pre-stamped; a structural engineer's stamp is offered for all 50 states and Canada as a checkout option and takes one to three weeks. The blueprints do not include detailed HVAC or plumbing layouts, which are set by local code and your subcontractors, and they assume prior construction knowledge rather than serving as a step-by-step build guide.
Want changes? The quote is free.
If you like Santa Ana but a few changes would make it perfect, Advanced House Plans can alter it. Every plan is drawn in house, so the people who change it are the people who designed it. The most common changes are priced up front on the plan page, and anything beyond those gets a free written quote.
Drawn in house
Every plan is designed by Advanced House Plans themselves, so an alteration goes straight to the original designer instead of through a third-party drafting service.
Free quote in one business day
Send an alteration request from the plan page and a written quote comes back within one business day. If you accept it, they send an online contract to sign and pay. Nothing is owed for the quote itself.
Common changes priced up front
Exterior wall type, foundation, a reversed plan, a site plan, editable CAD files and an unlimited build license are all priced on the plan page itself. The options and prices that apply to this plan are listed above.
What will it cost to build this house plan?
Plan price is one number. Construction cost is the number that decides whether you build. Advanced House Plans runs a free Cost Estimator on every plan page: enter a zip code and it prices Santa Ana against real local new-construction records.
Your zip code, real records
The estimator pulls real estate records for new construction in your area to get an all-in cost per square foot, which includes builder fees, excavation, realtor fees and even lot cost.
Adjusted for this plan
That cost per square foot is applied to this plan's total finished area, then adjusted for features the average does not cover, such as extra garage space and large covered porches or patios.
Low to high, by finish level
The result is a range you can move by choosing a finish quality. Advanced House Plans is explicit that it is a ballpark, not a number to use for financing or to hold a builder to. For that, get the plan bid by a contractor.
