10 Factory-Built Housing (FBH) HCD generally does not perform plan review or inspections for FBH projects in-house. Design Approval Agency plans review Quality Assurance Agency - inspections Local building department on-site Once FBH units are delivered to their permanent site, they become the Local Enforcing Agency s jurisdiction and shall be treated similarly to siteconstructed dwelling units. 8

11 In-Plant Inspections The under-construction inspection of FBH manufactured products may be made by: HCD Third-parties approved by HCD (QAA/QAI) The city or county building departments approved by HCD. 9

12 Design Approval, Inspections and Installation HCD provides rules and regulations pertaining to plan approval and in-plant inspections. Includes FBH products manufactured out-of-state and intended for sale in California. 10

13 Plan Approvals Plan approval is required for every FBH model/ design that is designated for sale in California. Design approval is performed by an HCDapproved third-party Design Approval Agencies (DAA). Approved designs must include a resume of what installation work is to be done on-site. 11

14 Plan Approvals Cont d DAA may plan check and evaluate all related building systems, i.e., wall, floor, foundation, roof (truss), plumbing, electrical, and mechanical, including all site-installed elements, preempting local plan review. Plans must contain separate details regarding on-site assembly and attachment of FBH components to foundation and surrounding structure, for use by local building department in plans review and site inspection. 12

15 Assembly and Installation The building department is responsible for inspecting the assembly and installation of FBH units. Approach the building department early to communicate the project details. When certified to inspect by department, a local ordinance may designate the collection of additional fees when necessary to cover the cost of factory inspections required to assure compliance by the building department. 13

16 FBH Licensing Requirements State law does not require FBH manufacturers, dealers or distributors to obtain an HCD occupational license to construct or sell FBH units in CA. Any person who is appropriately licensed by the California Department of Real Estate may sell FBH units. Any person who is licensed by the Contractors State Licensing Board to construct conventional housing may install FBH units. C-47 General Manufactured Housing Contractor may not contract to install factory-built housing units. 14

17 Responsibilities of Local Governments State law establishes two principal roles for local government: First, design approval of the portions of the project that have not been approved previously by HCD or an HCD third-party agency. Second, permit issuance and inspection of the installation and assembly of FBH units at the building site. 15

18 Responsibilities of Local Governments Cont d The local building department must: Verify the presence of HCD Insignia of Approval on each FBH system or component. Inspect the installation of FBH units and components for compliance with the CBSC, Title 24 as applicable to residential occupancies.

19 Local Governments - Statutory Obligations The local building department, may not: Require review of any FBH plans or charge plan check fees when plans have already been approved by HCD or an HCD-approved third-party. Require the alteration of any FBH unit, including any building component system, in order to meet any local code requirements other than local design loads, or aesthetic/ architectural review standards, or location on the property. 17

21 Factory-Built Housing Insignia of Approval All factory-built housing systems or components, offered for sale within California to first users, shall bear an HCD Insignia of Approval. The Insignia of Approval displayed on the product informs the local building official that the FBH unit or component was inspected and conforms to California laws and regulations, including applicable building standards. 19

22 Summarized FBH Process Manufacturer contracts with a QAA and DAA approved by the Department The FBH system or component design is approved by the DAA The FBH system or component is manufactured and inspection by the QAA / QAI or the equivalent Upon final approval, the FBH system or component receives an HCD insignia of approval The FBH system or component is shipped in sections to the project site The FBH system or component is assembled by the installing contractor Inspections are conducted by the local authority having jurisdiction (AHJ) per the manufacturer provided installation instructions The FBH product is then under local responsibility henceforth and the HCD FBH labels may be removed Any alteration, remodels or conversions to the FBH system or component are permitted by local AHJ. 20
