Building your own home shouldn't cost a fortune in plans.
HomePlanDIY started with a simple frustration: the big plan portals charge $700–$2,000 for a set of drawings — before a single board is cut. We believed owner-builders deserved better.
Every plan we publish is professionally drawn, build-ready, and delivered instantly: dimensioned floor plans, elevations, sections, electrical, plumbing, framing details, and a complete material list. PDF and editable CAD, so your builder or engineer can adapt it to your site.
— The HomePlanDIY team
“The CAD files meant our engineer could adapt everything for our county's snow load. A fraction of what the big sites quoted.”
“Instant download was the clincher. Clean drawings, smart layout, and the loft plan is exactly what we wanted.”
Frequently asked questions
What files do I get when I buy a plan?
Every purchase is an instant download with print-ready PDFs and editable CAD (.dwg) files: dimensioned floor plans, elevations, sections, slab/foundation layout, electrical, plumbing, framing details, door & window schedule, and a complete material list.
Will these plans meet my local building code?
Our plans are drawn to the 2021/2022 IRC standard. Local requirements vary by state, county, and city — some areas require a local engineer or architect to review and seal plans before permitting. We strongly advise checking with your building department before ordering; our CAD files make local adaptation straightforward.
Can you modify a plan for my lot?
Yes. Our team customizes any plan — move walls, add a bedroom, change the foundation or roofline. Use the Modification CTA on any plan page for a quick estimate.
How is this so much cheaper than other plan sites?
We sell direct, digitally, with no printing or shipping. Comparable plans elsewhere run $700–$2,000; ours deliver the same core construction set instantly for a fraction of that.
What is your refund policy?
Because plans are digital and delivered instantly, all sales are final — but if a file issue ever occurs we will fix it fast or make it right. Contact support any time.
