FAQs
Prefab homes in Delaware
Is Delaware coast-rated construction required for prefab?
Sussex County coastal zones commonly need 130+ mph wind design and elevated foundations in V/AE flood zones. Inland New Castle and Kent lots are closer to standard IRC packages.
How fast are Delaware permits?
County approvals often run about 4–8 weeks. Sussex coastal projects can take longer when wetlands or floodplain review is triggered.
Modular vs manufactured in Delaware?
Modular on a permanent foundation is usually construction-to-perm / real-property lending. HUD-code manufactured homes may need different products. Confirm labeling before you deposit.
What should a Delaware factory-vs-site quote include?
Factory package, delivery, crane, foundation or elevation, utilities, and any coastal wind or flood upgrades. Compare at least three written scopes rather than catalog price per square foot.
