D.C. Mun. Regs. tit. 17, r. 17-3305
The Director shall send a renewal application to a practitioner by first class mail to the practitioner's address on file with the Director at least sixty (60) days prior to the expiration of the license.
The practitioner shall meet all of the requirements for renewal prior to the issuance of the renewal.
A practitioner shall notify the Department in writing of any change of home or business address within thirty (30) days of the change of address.
The failure of a practitioner to receive the notice required by § 3305.1 does not relieve the holder of the responsibility of renewing the license.
A practitioner who fails to renew prior to the expiration date may renew the license within sixty (60) days after expiration upon paying the required late fee. Upon renewal, the practitioner shall be deemed to have possessed a valid license during the period between the expiration of the license and the renewal thereof.
If a practitioner fails to renew the license within sixty (60) days after its expiration, the license shall be deemed to have lapsed on the date of expiration, and the practitioner shall be required to apply for reinstatement and pay the required reinstatement fee.
The Director may require an applicant for renewal to provide information on the application for statistical purposes.
