| 1. Land Ownership |
Confirm that you own the parcel or have written authorization to place a dwelling on it. Review the legal description, access rights, utility easements, and recorded restrictions. |
Recorded deed, title report, survey, easement documents, and subdivision restrictions. |
Required |
A home may not be legally deliverable or occupiable if the site lacks lawful access, sufficient rights, or approved use. |
| 2. Zoning District |
Ask the local planning department whether the proposed home is allowed as a manufactured home, modular home, accessory dwelling, recreational unit, or another residential structure. |
Current municipal or county zoning map, zoning ordinance, and written zoning determination. |
Required |
“Portable” is a marketing description, not a universal legal classification. Local zoning controls whether the unit may be placed and occupied. |
| 3. Minimum Lot Standards |
Check minimum lot area, frontage, setbacks, maximum lot coverage, building height, parking, open-space rules, and any design requirements. |
Local development code and site-plan requirements. |
Required |
A compliant home can still be rejected if the parcel cannot satisfy dimensional or parking requirements. |
| 4. Home Classification |
Identify whether the unit will be treated as a HUD-code manufactured home, a state-code modular home, a site-built structure, a recreational vehicle, or another category. |
Manufacturer specifications, certification documents, state approval records, and local zoning definitions. |
Required |
Classification affects construction standards, installation rules, foundation requirements, taxes, title, and permitting. |
| 5. HUD Code Eligibility |
If the home is a manufactured home, confirm that it was built for the federal manufactured housing program and carries the required certification label and data plate. |
HUD Manufactured Home Construction and Safety Standards, 24 CFR Part 3280; certification label and data plate. |
Required for HUD-code homes |
A home advertised as “tiny,” “portable,” or “park model” is not automatically a HUD-code manufactured home. |
| 6. Construction Date |
Verify the date of manufacture and the standards applicable at that time. Confirm whether additions, alterations, or conversions were completed after manufacture. |
Data plate, certification label, purchase documents, alteration records, and inspection reports. |
Document Review |
Older homes may be subject to different requirements, while unapproved alterations may create safety and permitting problems. |
| 7. Site Preparation |
Evaluate soil conditions, grading, drainage, frost depth, slope, wind exposure, seismic conditions, and the location of utility connections. |
Site plan, geotechnical information where required, drainage plan, and local installation requirements. |
Required |
Site conditions determine foundation design, anchoring, flood protection, and whether delivery equipment can reach the parcel. |
| 8. Foundation and Anchoring |
Determine whether the jurisdiction requires a permanent foundation, pier system, slab, crawl space, basement, tie-downs, or engineered anchoring. |
24 CFR Part 3285 installation standards, manufacturer installation instructions, engineered plans, and local code requirements. |
Required |
Improper support or anchoring can prevent final approval and may increase wind, settlement, and moisture risks. |
| 9. Building Permit |
Confirm which permits are needed for placement, foundation work, structural connections, alterations, decks, stairs, porches, garages, and other site improvements. |
Local building department permit checklist and approved construction drawings. |
Required |
Ordering before permit confirmation can result in a home that cannot legally be installed or occupied. |
| 10. Utility Connections |
Verify water, wastewater, septic, electrical, gas, communications, and fire-access requirements. Check whether public connections are available at the property line. |
Utility availability letters, septic approval, electrical permit, plumbing permit, and utility-provider requirements. |
Required |
Utility extension costs can materially change the project budget and schedule. |
| 11. Floodplain and Environmental Review |
Check the official flood hazard designation, required elevation, foundation limitations, wetlands, protected areas, wildfire exposure, and stormwater obligations. |
Current flood maps, local floodplain ordinance, environmental permits, and site-specific review. |
Location Dependent |
Floodplain rules may require elevation, special foundation design, flood openings, or additional approvals before placement. |
| 12. Transportation and Delivery |
Measure road width, bridge limits, turning radius, overhead clearance, gate width, driveway grade, and staging space for cranes or delivery equipment. |
Delivery route survey, transportation permit requirements, and site logistics plan. |
Location Dependent |
A legally permitted home may still be impossible or unusually expensive to deliver to a restricted site. |
| 13. Installation Inspection |
Confirm who is responsible for installation, foundation inspection, utility inspections, anchoring verification, and correction of deficiencies. |
Local inspection schedule, state installation program, approved plans, and installation documentation. |
Required |
Passing installation inspections is commonly necessary before the final approval or certificate of occupancy. |
| 14. Certificate of Occupancy |
Obtain written confirmation that the dwelling may be occupied after all required inspections and corrections are complete. |
Certificate of occupancy, final inspection approval, or equivalent local authorization. |
Required |
Possession or delivery does not necessarily mean the home is approved for residential occupancy. |
| 15. Budget and Contract Terms |
Separate the home price from land preparation, foundation, transportation, permits, utility work, taxes, inspections, insurance, and contingency funds. |
Itemized contract, site-work estimate, permit fee schedule, payment milestones, cancellation terms, and warranty documents. |
Required |
Many project costs arise outside the advertised home price, and site approval should be confirmed before non-refundable ordering. |
