What Is a BCIN Designer? Ottawa Homeowner Guide
📋 Quick Answer
A BCIN designer is a building design professional who has passed Ontario Building Code examinations and is registered with the Ministry of Municipal Affairs and Housing. BCIN stands for Building Code Identification Number — a unique five-digit registration number that must appear on all drawings submitted for a building permit in Ontario. For most residential projects in Ottawa, a BCIN designer is the most cost-effective qualified professional to prepare your permit drawings — no architect required.
If you have ever looked into getting a building permit in Ottawa, you have probably come across the term “BCIN” on City forms, designer websites, and contractor advice. But most homeowners do not know what it means — or why it matters for their project. This guide explains everything you need to know about BCIN designers, what they are qualified to do, how they compare to architects and engineers, and when you actually need one for your Ottawa renovation or construction project.
At Architectural Drawing, our team holds BCIN qualifications and prepares permit drawings for residential projects across Ottawa. We are the BCIN designer you can rely on for building permit drawings that get approved.
What Does BCIN Stand For?
BCIN stands for Building Code Identification Number. It is a unique five-digit registration number assigned by Ontario’s Ministry of Municipal Affairs and Housing to qualified building professionals — including designers, building officials, inspectors, and registered code agents.
The BCIN system was created by Bill 124 (the Building Code Statute Law Amendment Act), which was proclaimed into law in 2003 and took effect January 1, 2006. Before Bill 124, anyone could prepare building permit drawings in Ontario without demonstrating building code knowledge. Bill 124 changed that by requiring all designers submitting drawings for building permits to be qualified, registered, and insured.
Today, when you hire a BCIN designer, you are hiring someone who has:
✅ Passed OBC exams — Demonstrated knowledge of the Ontario Building Code through formal examinations administered by Humber Polytechnic
✅ Registered with MMAH — Holds an active registration in the province’s QuARTS system (Qualification and Registration Tracking System)
✅ Carries liability insurance — Maintains professional liability insurance as required by Bill 124, protecting you if design errors occur
✅ Renews annually — BCIN registration must be renewed every year with proof of current insurance and may be subject to retesting
BCIN Qualification Categories
Not all BCIN designers are qualified for the same project types. The Ministry assigns qualifications based on which examinations the designer has passed. Here are the categories that matter most for Ottawa homeowners:
For the vast majority of Ottawa residential projects — custom homes, additions, renovations, basement apartments, and garages — a designer with the House qualification is all you need.

BCIN Designer vs Architect vs Engineer
One of the most common questions Ottawa homeowners ask is whether they need an architect, an engineer, or a BCIN designer. Here is how the three compare — and when each is required:
The key takeaway: for most Ottawa residential projects, a BCIN designer is all you need for the architectural drawings — floor plans, site plans, elevations, cross sections, and construction details. If the project involves structural modifications like removing a load-bearing wall, the BCIN designer coordinates with a P.Eng. for the structural component. For a deeper comparison, see our architect vs architectural technologist guide.
The Homeowner Exemption: Can You Skip the BCIN?
Ontario’s Building Code (Part C, Article 3.2) allows a homeowner to take design responsibility for drawings related to a house they personally own — including ancillary structures like garages and sheds. This is called the homeowner exemption.
If you use the exemption, you fill out the Schedule 1 form declaring yourself as the designer and writing “homeowner” as the basis for exemption. You do not need a BCIN number in this case.
⚠️ Important caveat: The homeowner exemption waives the designer qualification requirement — it does not waive the drawing quality requirement. Your drawings must still be drawn to scale, fully dimensioned, and contain all the information the City requires. Freehand sketches and incomplete plans will be rejected. Most homeowners who attempt this find the deficiency cycles cost more in time and frustration than hiring a professional BCIN designer in the first place.
How to Verify a BCIN Designer’s Qualifications
Before hiring any BCIN designer, you can verify their credentials for free using Ontario’s public QuARTS Public Search Registry. Here is what to check:
1. Registration Status
Confirm the designer’s and firm’s BCIN registration is current — not expired, suspended, or revoked.
2. Qualification Category
Verify the designer holds the right category for your project (e.g., “House” for a residential renovation).
3. Design Firm Registration
Both the individual designer AND the firm they work for must have a BCIN. Drawings need both numbers.
When your BCIN designer submits drawings for your building permit, they must complete a Schedule 1: Designer Information Form that includes their name, BCIN number, firm BCIN, contact information, a description of the design work, and their signature taking responsibility for the design. This form is submitted with every permit application and is reviewed by Ottawa Building Code Services before your permit is processed. For details on the overall permit timeline and permit fees, see our dedicated guides.

Frequently Asked Questions
Do I need a BCIN designer or an architect for my Ottawa renovation?
For most residential renovations — including kitchen and bathroom remodels, basement finishing, additions, and secondary dwelling units — a BCIN designer is sufficient. Architects are typically only required for large buildings (Part 3 of the OBC), such as apartment buildings or commercial structures. A BCIN designer is both qualified and significantly more affordable for standard residential work.
Is BCIN the same as being a licensed architect?
No. A BCIN designer and a licensed architect are different credentials regulated by different bodies. Architects (OAA members) are exempt from needing a BCIN because their training already covers building code knowledge. A BCIN designer is specifically qualified under the Ontario Building Code to prepare drawings for building permits but does not hold the title “architect.” Both can prepare residential permit drawings — but architects typically handle more complex projects.
How much does a BCIN designer charge in Ottawa?
Fees depend on the project scope. A simple renovation drawing package typically costs $1,000–$3,000. Basement apartments and additions range from $2,000–$5,000. New custom homes are $5,000–$15,000+. For a full breakdown, visit our drawing costs guide.
What is a Schedule 1 form?
The Schedule 1: Designer Information Form is a mandatory document submitted with every building permit application in Ontario. It identifies the person taking design responsibility for the drawings — including their name, address, BCIN number (or homeowner exemption declaration), and a description of the design activities. Without a completed Schedule 1, Ottawa will not process your permit application.
Can a BCIN designer do structural engineering?
No. A BCIN designer can use standard OBC Part 9 span tables to specify framing sizes and spacing — but cannot perform custom structural engineering. For projects that require structural analysis — such as load-bearing wall removals, custom beam sizing, or non-standard foundations — a licensed Professional Engineer (P.Eng.) must design and stamp the structural components. A good BCIN designer coordinates with P.Eng. partners seamlessly.
Does a BCIN designer handle the permit application for me?
Many BCIN designers — including Architectural Drawing — offer permit application support as part of their service. This includes preparing the complete drawing package, completing the Schedule 1 form, submitting the application to the City, and responding to any deficiency letters during the review process.
Is the BCIN only for Ontario?
Yes. The BCIN system is exclusive to Ontario. Other Canadian provinces have their own qualification requirements for building designers. If your project is in Ottawa (or anywhere in Ontario), a BCIN designer is the qualified professional to prepare your residential permit drawings.
How do I find a BCIN designer near me in Ottawa?
You can search the QuARTS Public Search Registry for designers registered in your area. Alternatively, contact Architectural Drawing directly — we serve all of Ottawa and the surrounding region with BCIN-qualified residential design services.
What happens if my designer does not have a valid BCIN?
If drawings are submitted by a designer without a valid BCIN (and the homeowner exemption is not used), Ottawa Building Code Services will reject the application. You will need to hire a qualified designer to re-prepare and re-submit the drawings — costing you additional time and money. Always verify credentials before hiring.
Can a BCIN designer help with building inspections?
A BCIN designer does not perform official building inspections — those are conducted by City of Ottawa building officials. However, a good BCIN designer prepares drawings that are clear enough for inspectors to follow, and can help you understand the inspection requirements for each stage of your project. Some designers also offer site visits to ensure construction matches the approved drawings before you call for an inspection.
