What we do
We believe that building a new home or ADU should be an exciting and rewarding experience, not a source of stress.
Complimentary Site Review & Model Match
We start with a no-cost walk-through of your property—checking setbacks, utilities, and overall feasibility. Next, we help you choose the prefab or manufactured model that makes the most sense for your lot, budget, and timeline. Clear guidance up front means no rude surprises down the road.
Hassle-Free Permitting
All plan sets, engineering calcs, and Title 24 docs are drafted and submitted by our team. We track every comment from city and county reviewers and keep you posted, but you never have to stand in line at the building counter. Most permits clear in 6-8 weeks, saving you months of paperwork headaches.
Site Preparation & Foundation Work
While the factory builds your home, our crew grades the lot, pours the engineered foundation, and brings power, water, and sewer to the pad. Coordinating both tracks in parallel keeps the project moving even when others stall. When the modules arrive, the site is plug-and-play ready.
Factory Build, Delivery & Set-Up
Your home is constructed indoors under strict QC, then trucked and craned onto the foundation in a single day. We bolt, seal, and weather-proof the structure, connecting all utilities with minimal neighborhood disruption. Indoor fabrication plus rapid on-site assembly means you’re weeks—not months—away from move-in.
Final Touches & Support
Our team completes siding, roofing tie-ins, interior trim, and any custom finish items, then walks the whole job with you for sign-off. We handle the final inspection so you get a green tag without the stress. After hand-over, you have a direct line to us for warranty questions—because reliability doesn’t stop at the front door.

“We've worked with MyPrefabHomes on a couple projects and were thoroughly impressed by their professionalism and the quality of their work. They completed the project on time and within budget, making our dream of adding a functional and stylish space to our property portfolio a reality. ”
Joe Stokley, Jr. — Principal-Broker, Stokley Properties, Inc.
"I purchased a Silvercrest manufactured house through JPW Development as an ADU for my aging in-laws. I couldn't be happier with my decision. The Silvercrest product is a quality home that exceeded our expectations. More importantly I was incredibly impressed with the professionalism and expertise of the JPW Development team. Overall, I couldn't be more pleased with experience and my new ADU from JPW Development."
Mrs. O'Gara
"We really enjoyed working with John Piccolo Wignall and his wife Terri on the purchase of our manufactured home. They kept us informed on the status of construction. From start to finish all involved were great at communicating with us, fair with us when unexpected expenses arose, and completed the project in a timely manner. I highly recommend JPW Development Co on a project like ours!"
