Prepare the site before your modular home is delivered by confirming permits, boundaries, ground conditions, foundation requirements, drainage, utility connections, and delivery access. I recommend using the home supplier’s approved drawings and coordinating them with your local designer, engineer, contractor, and utility providers before excavation begins. Site requirements vary by location, home design, transport method, and foundation type, so this checklist is a planning tool—not a substitute for project-specific engineering or local approval.

A well-coordinated site can help reduce avoidable delays during installation, but modular construction does not remove the need for careful ground preparation. Confirm responsibilities and dates in writing, especially where several contractors or authorities are involved. Use the steps below to identify open questions before the home is ready to ship.
Ask your modular home supplier for the current project documents needed for site coordination. Depending on the design and local process, these may include a floor plan, module or section dimensions, foundation interface details, connection locations, and delivery or lifting information. Check that the versions being used by your site contractor match the versions approved for your project.
Local authorities determine which permits, inspections, setbacks, and technical documents apply. Confirm requirements directly with the relevant building department and qualified local professionals rather than assuming that another project’s approval process will apply. If the site is in a managed community or has access restrictions, check those rules before scheduling construction traffic.
Write down who is responsible for permits, survey work, excavation, foundation construction, utility connections, inspections, and delivery coordination. Ask each party to identify information they still need and the latest date it can be provided without affecting the agreed schedule. This simple coordination step can expose missing approvals or conflicting work sequences early.
Confirm property boundaries and the proposed home position using project documents and, where needed, a qualified surveyor. Check setbacks, easements, access rights, overhead restrictions, and underground services before placing the foundation or planning a crane position. Do not rely on visible fences alone as proof of a legal boundary.
Record the site’s existing ground levels and identify slopes, low points, retaining walls, trees, and neighboring structures that may affect construction. A survey plan should use a clear unit system and datum so the designer, foundation contractor, and installer can compare levels consistently. For example, a 1:100 fall is equivalent to 10 mm per 1 m; this is a conversion, not a recommended drainage grade for every site.
Soil bearing capacity, groundwater, fill, rock, and unstable ground can affect foundation design and construction methods. Ask the local engineer or design professional whether a geotechnical investigation is required for your site and what information is necessary before foundation work. Do not select or alter a foundation based only on a neighboring building or a generic online specification.
Confirm the foundation type, dimensions, bearing points, anchor or connection locations, and tolerances against the approved design for your home. The foundation contractor should know which measurements and inspections must be completed before the modules arrive. If the site conditions differ from those assumed in the design, pause and ask the responsible engineer or designer to review the change.
Before covering or pouring work that will later be hidden, confirm which inspections or records are required locally. Keep relevant survey checks, inspection approvals, and foundation completion information available for the installation team. Resolve discrepancies before delivery rather than expecting the crew to correct structural or dimensional issues on arrival.
Decide how surface water will be directed away from the home and where roof runoff, temporary construction water, and site drainage will go. The appropriate solution depends on local rules, soil, slope, neighboring properties, and the approved design. Avoid directing water onto adjacent land or into a location that could affect the foundation, access route, or work area.

Identify the planned connection points for electricity, water, wastewater or sewer, communications, and any other services included in the project. Ask the supplier and local trades to confirm how the home’s connection locations align with the site routes and service-provider requirements. Mark routes and connection points on a coordinated plan before excavation.
Confirm whether services must be installed, inspected, or left accessible before the home is set in place. Utility providers may have their own application, connection, capacity, and scheduling processes, so contact them early. Keep service records and site markings current, particularly if underground work is carried out in stages.
Discuss delivery dimensions and transport arrangements with the supplier or logistics coordinator. Review the route from the public road to the installation point, including gate openings, turning areas, road restrictions, overhead lines, surface strength, gradients, and any narrow or low-clearance sections. A route that appears suitable for a car may not accommodate the transport equipment required for a modular home.
Record measurements from the actual route and share them with the party responsible for transport planning. For example, note a measured 4.0 m entrance width as a site observation, not as a universal minimum; the required clearance depends on the delivery configuration and route conditions. Confirm any restrictions with the relevant road authority, property manager, or transport provider.
Ask the installation or lifting team what space, ground conditions, access, and equipment arrangements are required for unloading and placement. Keep the work zone clear of stored materials, parked vehicles, and avoidable obstructions. Confirm the planned crane or other placement equipment location and whether the supporting ground needs assessment by a qualified professional.
Agree on a delivery window, site contact, communication method, and contingency process for weather or access problems. Make sure the installation team can reach the site safely and that required permits or traffic arrangements are in place. The exact equipment and setup should be determined for the specific home, route, and site—not assumed from a generic checklist.
One common mistake is beginning excavation before the home layout and foundation information are coordinated. Another is checking only the driveway entrance while overlooking turns, overhead obstacles, soft ground, or restrictions farther along the route. These issues can lead to redesign, rework, or a rescheduled delivery.
It is also risky to assume utilities will be ready automatically or that all inspections happen in the same order everywhere. Confirm responsibilities and lead times with the relevant provider and authority. If a contractor proposes a site change, have the appropriate designer or engineer review its effect on the home and installation before proceeding.
The practical answer is to complete approvals, site checks, foundation coordination, drainage planning, utility preparation, and delivery-access review before scheduling the modular home’s arrival. Start with the supplier’s current documents, then confirm site-specific requirements with local authorities and qualified professionals. Keep a written checklist of open items, responsible parties, and completion dates so that unresolved work is visible before delivery.
At Hongshun Guangju, we encourage buyers and project teams to coordinate site conditions and home requirements early in the sourcing process. Share your project location, intended layout, foundation approach, and delivery constraints with our team when requesting information. This helps establish which product and technical details need confirmation before you move into site preparation and installation planning.
