License Verification

The Landscape Architects Technical Committee (LATC) licenses individual landscape architects, not firms or corporations. California landscape architect licenses expire on the last day of the licensee’s birth month and must be renewed every two years.

The LATC has provided a database which allows you to access the current listing of landscape architects by license number, name, or city. Delinquent, expired, suspended, or revoked licenses are not listed in this database.

This information was last updated: October 19, 2018

The information is computer-generated and subject to change as licenses are issued, expire, are renewed, revoked or suspended, or as name and address changes are filed with the LATC.

For the most current information, you may telephone (916) 575-7230 or send an email with your request to the LATC at A response will be transmitted to you within 48 hours of your inquiry. Be aware that public information for licensees is restricted to license number, name, address of record, license issue and expiration dates, and enforcement and disciplinary actions. Telephone numbers are not provided.

If you would like to report an unlicensed person, please include that request or information in your email.

Enforcement Actions are available on the LATC website for five years. Please contact the LATC to check on any enforcement actions beyond five years.
