Steps
Confirm the project falls under HCAI's regulatory scope; the OPM preapproval program is limited to seismic design of supports and attachments for manufacturer-certified equipment.
Check whether the equipment/casework manufacturer already holds an active OPM preapproval number for the applicable anchorage condition.
If not preapproved, coordinate with the project structural engineer to submit project-specific seismic anchorage calculations instead of relying on an OPM.
Confirm which edition of the California Building Code governs the review, since HCAI updates its review basis on a code-cycle schedule.
Direct specific applicability questions to HCAI's OPM program contact rather than assuming general millwork always requires this preapproval.
Known gotchas
OPM preapproval is scoped narrowly to seismic anchorage of supports/attachments — it is not a general product-quality certification and does not substitute for AWI/WI casework compliance programs.
HCAI's program was formerly branded under OSHPD; older documents/forms may still reference 'OSHPD OPM' — confirm you're using the current HCAI-branded process and forms.
