What Architects Can Do
- Design buildings of any size or complexity
- Work on commercial, institutional, and residential projects
- Design schools, hospitals, churches, and assembly buildings
- Provide full project management from concept to completion
- Sign and seal drawings without BCIN certification

- Complete a 2-3 year college diploma in Architectural Technology
- Obtain BCIN certification from the Ministry of Municipal Affairs and Housing
- May join the Association of Architectural Technologists of Ontario (AATO)
- Focus on construction documentation, building codes, and technical drawings
Architectural technologists are experts at translating design concepts into detailed construction documents. They have in-depth knowledge of the Ontario Building Code, construction methods, and permit requirements.
What Architectural Technologists Can Do
- Design residential homes (with size limitations)
- Prepare permit drawings and construction documents
- Perform building code analysis
- Create CAD drawings and 3D models
- Coordinate with engineers and contractors
- Submit drawings for building permit approval
What Is a BCIN Number?
The Building Code Identification Number (BCIN) is a license issued by Ontario’s Ministry of Municipal Affairs and Housing (MMAH) that certifies a designer’s knowledge of the Ontario Building Code.
Key Facts About BCIN
- Required for: Architectural technologists, technicians, and designers submitting permit drawings in Ontario
- Exempt: Licensed architects and professional engineers
- Qualifications: Multiple categories including House, Small Buildings, Large Buildings, Plumbing, and Septic
- Renewal: Annual renewal required with proof of insurance
To obtain a BCIN, designers must pass exams administered by the MMAH. The General Legal exam is mandatory, followed by qualification-specific exams based on the type of work they want to perform.

When You Need an Architect
You must hire an architect for your Ontario project if:
- Your building exceeds 600 m² (6,458 sq ft)
- Your building is more than 3 storeys
- You’re building a restaurant, church, school, or hospital

- Your project has complex site conditions or unusual requirements
- You’re building a high-end luxury home
- You need full project management services
- The design aesthetic is your top priority
When an Architectural Technologist Is Sufficient
An architectural technologist is typically the right choice for:
- Standard residential projects: Custom homes, additions, renovations
- Permit drawings: Permit documentation for straightforward projects
- Budget-conscious projects: When cost savings matter
- Code-focused work: Projects requiring deep building code expertise
- Secondary suites: Basement apartments and in-law suites

Frequently Asked Questions
What is the difference between an architect and architectural technologist in Ontario?
Architects have university degrees (5-7 years), are licensed by the OAA, and can design any building type without restrictions. Architectural technologists have college diplomas (2-3 years), require BCIN certification, and are limited to residential projects under 600 m² and small commercial buildings. Technologists focus on technical documentation while architects emphasize design aesthetics.
Do I need an architect to build a house in Ontario?
No, you don’t need an architect for most residential homes in Ontario. A BCIN-certified architectural technologist can design single-family homes, duplexes, and townhouses up to 600 m² (6,458 sq ft) and 3 storeys. You only need an architect if your home exceeds these limits or includes assembly/care occupancies.
What is a BCIN number in Ontario?
A Building Code Identification Number (BCIN) is a license from Ontario’s Ministry of Municipal Affairs and Housing certifying that a designer has passed exams on the Ontario Building Code. It’s required for architectural technologists, technicians, and designers to submit permit drawings. Architects and engineers are exempt from BCIN requirements.
Is an architectural technologist cheaper than an architect?
Yes, architectural technologists typically charge 30-50% less than architects for comparable services. While architects may charge 8-15% of construction costs, technologists often charge 5-10%. For a standard home renovation or addition, this can mean savings of several thousand dollars while still receiving professional, code-compliant drawings.
Can an architectural technologist stamp drawings in Ontario?
Yes, BCIN-certified architectural technologists can sign and submit drawings for building permits within their qualification scope. Their drawings include their BCIN number, which validates their authority to submit plans. However, some projects may require additional stamps from structural engineers or other specialists.
What projects require an architect in Ontario?
You need an architect in Ontario for buildings over 600 m² or 3 storeys, assembly occupancies (churches, restaurants over 30 persons, theatres), institutional buildings (schools, hospitals), care facilities (daycares, nursing homes), and multi-unit residential with stacked dwelling units.
