CALIFORNIA58 | HOUSING EXPLAINER | OCTOBER 18, 2026. A manufactured home can arrive from a factory, but buying the unit does not automatically give its owner permission to install and occupy it on a particular California parcel. The California Department of Housing and Community Development (HCD) states that contractors who install or prepare to move manufactured homes must hold a C-47 General Manufactured Housing Contractor license. That is a separate question from whether a county or city will approve the proposed residential use.

Two different approvals

First, land use: ask the planning department whether a manufactured home is permitted on the parcel, whether it must be on an approved foundation, and what setbacks, floodplain, fire access, utility and sewage requirements apply. A seller’s assertion that the lot is ‘buildable’ is not a permit. Second, installation and construction: confirm the responsible inspection agency and whether HCD or the local building department has authority over the particular work. HCD notes that factory-built housing installation is subject to inspection by the local building department, while permits for mobilehomes and parks can involve HCD or other authorized agencies.

Why the C-47 license matters

HCD explicitly identifies the C-47 requirement for contractors installing or preparing to move manufactured housing. Before signing a contract, check the contractor’s current license and classification with the Contractors State License Board, verify insurance and ask who will obtain each permit. A license alone does not override a zoning prohibition, and a land-use approval does not substitute for an appropriately licensed installer.

What the state says about fees and review

HCD’s permit guidance says some park-construction plan-review packages may take four to six weeks after submission, and it lists a preliminary plan-check meeting fee of $238 per hour with a one-hour minimum. Those examples apply to the specified HCD review process and are not a universal fee or approval timeline for putting a single manufactured home on private land. County charges, site work, transport, foundation, water, sewer and power can substantially change a project’s total cost.

Checklist before paying a deposit

  1. Get the parcel’s APN and written zoning confirmation from the city or county.
  2. Ask the building authority for its manufactured-home installation requirements and applicable forms.
  3. Check access for a transport vehicle, foundation engineering and utility capacity.
  4. Confirm floodplain and wildfire requirements and whether a private well or septic system can be permitted.
  5. Verify the installer’s C-47 classification and obtain itemized written quotes.
  6. Do not treat a preliminary discussion with staff as a final permit approval.
