Write down the name, email, and direct phone. You will need this person for the state modular label acceptance, the setback confirmation, and the driveway/curb-cut permit. Land Check surfaces the five questions to ask them.

Confirm in writing that they will accept the state modular label (or your state's equivalent) on your specific parcel. Keep the reply — you'll need it for closing.

Required if you're using a septic system, if your county mandates a perc test for new construction, or if the site sits on fill. Local surveyor or geotechnical firm — budget 2-3 weeks lead time.

Water, sewer or septic, electric service (amperage), gas if applicable, internet. Get written confirmation from each utility that they can serve your address at the required load.

Your GC handles the site prep, foundation, utility trenching, and set-day coordination. If you don't have one, ask your builder for referrals in your delivery radius — most modular builders keep a shortlist.

Your attorney reviews the manufacturer contract, the delivery + installation contract, and coordinates the closing package. Retainer typically $500–$2,500 depending on state.

Cash, conventional modular mortgage, FHA Title II, VA, chattel, or construction-to-perm. The Financing Finder identifies which lenders actually finance modular in your state. Open Financing Finder →

Get quotes for builder's risk during construction + standard HO-3 for post-occupancy. Modular is standard construction from an insurance standpoint — do not accept "mobile home" policies at higher premiums.

Not a text. A phone that will answer at 6am on set day. Usually the GC or you.

Modules are wide and tall. Your builder's transport team pre-scouts most routes — confirm they've done yours in writing. If your driveway or private road is tight, hire a route survey.

No exceptions. The crane cannot set on a foundation that isn't signed off by the county. Get the inspection scheduled with a buffer — a rain delay on inspection day means a rescheduled crane at $2K+ per day.

Water line, sewer or septic drop, electrical conduit, gas line if applicable. Positioned so the set crew can connect at the module's mechanical chase without re-trenching.

After the crane sets the modules, someone has to seal the marriage line, complete siding, hook up mechanicals, and finish interior connections. This is a 1–3 week phase your GC coordinates. Get the calendar on paper before set day.
