How to Prepare a Manufactured-Home Site and Coordinate Utilities

Coordinate the Property as One Project

Site preparation usually involves clearing and access, earthwork and drainage, and foundation preparation. Each part affects the others. The driveway must serve delivery equipment. The homesite must respect setbacks and septic areas. Utility routes must reach the final home position. Drainage must move water away without damaging the foundation or septic system.

Choose and mark the exact home location before crews clear, grade, trench, or build. Consider the delivery route, section orientation, foundation, driveway, utilities, septic or sewer, porches, HVAC equipment, parking, drainage, trees, and possible future additions together.

Confirm Permits and Responsibilities

Requirements vary by state, county, city, utility, health department, building department, home, and foundation. Ask each authority what approvals, plans, permits, inspections, and licensed professionals apply to the exact property.

Create a written responsibility list. Record what the dealer handles, what the buyer handles, which contractor performs each job, what must be inspected, and what has to finish before the next crew starts.

Use the Foundation Designed for the Project

Manufactured homes may use pier systems, concrete footers, engineered slabs, or other approved foundations. Basements are possible for some projects but require additional design and coordination and are more common with modular construction.

The correct system depends on the manufacturer’s installation instructions, approved design, soil, drainage, local requirements, lender, climate, and home. Do not build a generic pad from a neighbor’s experience. Get the requirements for the exact home and verify grading, soil preparation, footing locations, support, and inspection.

Utility routing also changes with the foundation. An accessible crawlspace may simplify plumbing and electrical work. A slab may require drains, sleeves, conduits, and connection points to be located before concrete is poured. Plan those details early.

Start Electrical Service Early

Once the home order is settled, the service address is valid, and the homesite is known, contact the serving electric utility. Ask where service can enter, whether it will be overhead or underground, what clearing or trenching is required, which equipment belongs to the customer, what inspections must pass, and how much scheduling lead time is typical.

Give the utility representative enough access to see the homesite and route. Save the current specifications and give them to the electrician. Requirements differ by provider, so do not copy another property’s installation.

Define the Water and Wastewater Work

For public water, confirm the meter location, connection charges, provider-owned equipment, customer-owned line, pipe specifications, trenching, inspection, and ownership boundary. Photograph customer-owned piping before it is covered.

For a well, coordinate drilling, the pump and pressure system, water testing, power, permits, treatment, and the connection to the home. For sewer, verify tap location, fees, line installation, and inspection. For septic, obtain the required soil and site approval, system design, permit, qualified installation, inspection, and final approval.

If the site does not support a conventional septic system, stop and understand whether an approved alternative exists and what it will cost to install, operate, inspect, and maintain.

Size and Sequence the HVAC System

Confirm the equipment, thermostat, outdoor pad, electrical disconnect, duct connection, condensate drainage, permits, startup, testing, and warranty. The installer should size the system for the final home order and local conditions rather than using square footage alone.

Electrical service generally must be available before final HVAC startup and testing. That makes electrical coordination an early task even though HVAC commissioning often happens near the end.

Document the Work and Protect the Schedule

Save applications, specifications, contacts, quotes, contracts, permits, inspections, invoices, changes, scheduled dates, and photographs of buried work. Track each remaining task, owner, dependency, and next date in one project list.

A home can be ready before the property is ready. Use the factory-production period to advance clearing, drainage, foundation, utilities, septic, permits, and inspections. Follow up before a missed handoff turns into weeks of delay.
