Third-Party Design Approval Agencies
Third-party agencies (PDF) are certified by the Department of Housing and Community Development's (HCD's) Manufactured Housing Program staff to perform as a Design Approval Agency (DAA) and/or a Quality Assurance Agency (QAA), enforcing design and construction approval of commercial modulars (CMs), special purpose commercial modulars (SPCMs), and multifamily manufactured homes (MFMHs) designated for sale in California.
Third-party agencies, once approved, provide these services as a small business acting on behalf of HCD.
Procedures for Quality Assurance Agency
For CMs, SPCMs, and MFMHs, the following items are required when applying for a Third-Party Agency Certification Approval:
- Required forms: Form HCD-MH 471 (PDF) is required for each person listed in the ownership structure.
- Organizational Structure: An organizational chart listing the names and job classifications of all persons subject to approval.
- List of California Engineer(s)/Architect(s) on DAA staff, including all staff, managers, supervisors, engineers, and architects who have not been previously approved by HCD.
All third-party agencies are required to report monthly to HCD using form HCD-MH 473. The report is due by the 15th of each month. The report provides information on all the activities of the QAA currently under contract in that reporting month. The HCD-MH 473 must be sent with forms HCD-MH 441 and HCD-MH 442, which detail each manufacturer’s production for each unit type (CM, SPCM, MFMH, Factory-Built Housing). If there has been no activity or no production by one of your client manufacturers, enter each manufacturer’s name and write “No inspection/insignia issued this month” on form HCD-MH 473 adjacent to the manufacturer’s name. Refer to Title 25, California Code of Regulations, Chapter 3, Section 4880 for more details.
