Prefab homes in Hawaii: modular & ADU builders
Modular, ADU, and factory-built companies serving Hawaii. Compare listings, then contact builders directly.
In this market
Prefab and modular home builders serving Hawaii must plan for shipping, limited plant proximity, and island-specific permitting. Use this list to find companies that advertise Hawaii delivery and to compare Prefably profiles and Unclaimed public listings.
Freight and crane logistics often dominate the budget. Ask for island-specific delivery notes and a clear split between factory package and site work.
Unclaimed listings are public directory records on Prefably. You can open each company profile to see location, ratings when published, phone when available, and the builder website, then contact them directly. We do not sell your inquiry as a lead. If you run the company, claim this listing free to correct details and mark it as claimed after our review.

FAQs
Prefab homes in Hawaii
Can prefab homes be shipped to Hawaii?
Yes. Modules and flat-pack kits commonly ship in containers from West Coast ports. Allow roughly 6–10 weeks of ocean transit plus island permit and set time.
What about Hawaii ADU rules?
Honolulu allows ADUs up to about 800 sq ft on qualifying lots. Maui, Kauai, and Hawaii County each set their own size and lot-area rules, so confirm the county before you order.
What dominates Hawaii prefab cost?
Freight, crane, and on-island site work often outweigh factory finish upgrades. Get haul, barge or container, and set line items in writing before comparing “price per square foot.”
Modular vs manufactured in Hawaii?
Ask which code path the quote assumes. Local-code modular and HUD-code manufactured products face different permitting and lending treatment even when both arrive by container.
