When Do You Need a Licensed Technologist?

A Licensed Technologist is someone granted a limited licence by the OAA to practise architecture in accordance with the conditions and limitations established in the regulations under the Architects Act.

In addition to the Exceptions enumerated in Section 11(3) of the Regulation under the Architects Act, a Licensed Technologist may offer architectural services to the public within the following protected scope of work:

  • residential occupancy containing one dwelling unit or two attached dwelling units, and, as constructed, enlarged, or altered, not more than four storeys;
  • residential occupancy containing three or more attached dwelling units, and, as constructed, enlarged, or altered, not more than four storeys and 600 m2 in building area; and
  • a restaurant for the consumption of food or drink intended to accommodate not more than 100 people that is not more than three storeys and not more than 600 m2 in gross area as constructed, enlarged, or altered. (See definitions on the right.)

Whether or not your project legally requires an OAA member, there are always significant advantages to retaining one of these highly skilled professionals with extensive training and experience.
 
The Architects Act establishes legal liability for those who misrepresent themselves as Licensed Technologists, or who practise architecture (or enable it) by non‐members. This liability extends to Authorities Having Jurisdiction (AHJs) (e.g. municipalities and townships) who elect to process applications in contravention of the Act.

When in doubt, contact the OAA’s Office of the Registrar to confirm whether the Architects Act applies to a particular project. Staff will respond promptly to help all parties understand how to comply with their legal requirements as they relate to the Act.

DEFINITIONS

Section 11 of the Architects Act offers the following definitions:

Building area means the greatest horizontal area of a building within the outside surface of exterior walls or, where a firewall is to be constructed, within the outside surface of exterior walls and the centre line of firewalls.

Gross area means the total area of all floors above grade measured between the outside surfaces of exterior walls or, where no access or building service penetrates a firewall, between the outside surfaces of exterior walls and the centre line of firewalls but in a residential occupancy where access or a building service penetrates a firewall, the measurement may be taken to the centre line of the firewall.
