HUD places requests in its routine or complex track based on the amount of work and time involved in processing the request. The criteria for assignment to a specific track can be found in HUD's FOIA Regulations, 24 CFR 15.104(d).

When you receive your acknowledgment letter from the Department, you will be advised whether your request has been assigned to the routine or complex track. If your request has been assigned to the complex track, you will be advised in the acknowledgment letter of your opportunity to consult with the FOIA Specialist handling your request to determine whether your request can be modified and transferred to the routine track.
