Complete permit packages – one submission, no missing pieces
Most permit drawing problems in Toronto come from the same three sources.
And all three are avoidable when the drawings are done right the first time.
- The drawings were incomplete – and the city sent them back – Toronto’s building permit reviewers return applications that are missing information, have inconsistencies between drawings, or don’t demonstrate code compliance. Every return resets the clock. A project waiting on a permit that’s been returned twice has lost six to ten weeks before construction starts.
- The designer prepared drawings without understanding how the building would be built – Drawings that look correct on paper but don’t reflect the actual structure, the existing conditions, or the physical constraints of the site create problems during construction – changes, delays, and additional costs. Good permit drawings are grounded in how a building actually goes together, not just how it looks in plan.
- The project started without the right permits – and stopped – Stop-work orders are issued when construction begins without required permits, or when work doesn’t match the approved drawings. The consequences — fines, mandatory demolition of unpermitted work, insurance complications – are serious and entirely avoidable. The permit process exists for good reasons, and navigating it properly protects the homeowner.
Building design from people who understand both sides of the drawing – and both sides of the wall.
Sandra and Johanna graduated as architects in Venezuela and have 10 years of construction experience across three countries. That combination changes how we approach permit drawings — we understand what the drawings need to show, and what happens when they meet a real building site.
All permit drawings we produce are reviewed and stamped by a licensed BCIN designer or engineer before city submission.
We prepare complete permit packages — architectural drawings, site plans, structural engineering coordination, and all supporting documentation. We review existing conditions thoroughly before drawing anything, because drawings that don’t reflect reality create problems during construction, not on paper.
And because we also build what we design, our drawings are buildable — not just approvable.
What you get when design and construction knowledge come from the same team
Drawings grounded in construction reality
We know what a contractor needs from a set of drawings to do the work correctly. Dimensions that reflect actual site conditions. Details that can be built with standard trades and materials. No drawings that look complete on paper but leave questions unanswered in the field.
Complete permit packages – submitted right the first time
Missing information is the most common reason Toronto permit applications are returned. We prepare thorough packages: architectural drawings, site plan, structural coordination, and all required supporting documentation. One submission, no missing pieces.
Design thinking alongside technical compliance
Permit drawings are not just a regulatory requirement – they are the document that defines what gets built. We bring architectural training to that document, so the space that gets approved is also the space that works well for the people living in it.

How We Work With You
STEP 1: Book a free 15-minute call
We talk about your project – what you are planning, what you know about the existing conditions, and what the permit requirements are likely to be. We will tell you honestly what is involved and whether we are the right fit.
STEP 2: Site review and design development
We review the existing conditions, confirm zoning compliance, and develop the design. You see the drawings in progress – before anything is finalized, so the permit drawings reflect decisions you have made, not assumptions we made for you.
STEP 3: Complete permit package – reviewed, stamped, submitted
We prepare the full package: architectural drawings, site plan, structural coordination, and supporting documentation. A licensed BCIN designer or engineer reviews and stamps. We submit to the city and manage the review process through to approval.
10 Reasons Why Clients Choose Us
Everything you need to bring your custom home to life — start to finish.
- We prepare drawings that reflect how a building actually goes together. Sandra and Johanna (founders) have 10 years of construction experience. Our permit drawings don’t just look correct in plan — they reflect the existing conditions, the structural reality, and what a contractor actually needs to build the work correctly.
- Architectural training behind every drawing We graduated as architects in Venezuela. We think about proportion, how spaces connect, and how the building relates to its site — not just how to satisfy the minimum requirements of a permit submission.
- Licensing: All permit drawings are reviewed and stamped by a licensed BCIN designer or engineer before city submission.
- Complete packages — submitted right the first time: Incomplete applications are the most common reason Toronto permits are returned. We prepare thorough packages: architectural drawings, site plan, structural coordination, and all required supporting documentation. One submission, no missing pieces.
- We coordinate structural engineering — you don’t manage it: Where structural drawings are required, we coordinate with licensed structural engineers. You have one point of contact for the complete permit package. You don’t manage a separate engineering relationship alongside us.
- We know the Toronto zoning by-laws and Ontario Building Code: We review zoning and code requirements at the start of every project, before any drawings are produced. No surprises at the permit submission stage because a setback or height limit wasn’t checked upfront.
- We design for the people living there, not just for the permit reviewer: A permit drawing defines what gets built. We bring design thinking to that document — so the space that gets approved is also the space that works well and holds up over time.
- We understand older Toronto homes: Pre-1980s Toronto homes present conditions that need to be understood before drawings are produced: irregular framing, non-standard dimensions, hidden structural elements. Drawings based on assumptions rather than actual conditions create problems during construction.
- Garden suites and laneway houses handled properly: Toronto’s garden suite and laneway housing programs have specific zoning requirements that need to be confirmed before design starts. We conduct the zoning analysis first, then design within what’s actually permitted — not what looks good before the numbers are checked.
- City of Toronto Building Renovator licence: We hold the City of Toronto Building Renovator licence. That means we don’t just prepare the drawings — we can also supervise the construction that follows, with a single team responsible for design, permit, and build.

Frequently Asked Questions
Q: What is a building designer in Ontario, and what can they do?
In Ontario, a building designer is a professional qualified to prepare the drawings required for a building permit under the Ontario Building Code. The specific licence is called a BCIN (Building Code Identification Number), issued by the Ministry of Municipal Affairs and Housing after passing a series of technical exams.
A licensed BCIN designer can prepare permit drawings for houses, additions, renovations, and low-rise buildings up to a defined scope. For larger or more complex projects, a licensed engineer or architect may be required to review or stamp the drawings.
We want to be transparent about where we are: Sandra and Johanna both graduated as architects in Venezuela and have 10 years of construction experience. Sandra is currently preparing for the BCIN designer exams. In the meantime, all permit drawings we prepare are reviewed and stamped by a licensed BCIN designer or engineer before submission to the city. The drawings themselves are produced by us – the review and stamp ensure full code compliance and legal submission.
Q: Do I need a building designer for my renovation or addition in Toronto?
For most meaningful renovation projects in Toronto – anything involving structural changes, additions, new construction, or significant alterations to plumbing, electrical, or mechanical systems – you will need permit drawings prepared or reviewed by a qualified professional.
Simple cosmetic work (painting, flooring, replacing fixtures in the same location) typically does not require permit drawings. But as soon as you are removing walls, adding square footage, finishing a basement, building an addition, or constructing a garden suite, you are in permit territory and you need drawings that meet Ontario Building Code requirements.
The risk of submitting incomplete or non-compliant drawings is significant: the city returns the application, the clock resets, and your project timeline extends by weeks or months. We prepare thorough, code-aware drawings from the start to minimize that risk.
Q: What is the difference between a building designer, an architect, and an engineer?
An architect (licensed by the Ontario Association of Architects) is qualified to design and seal drawings for any type of building. In Ontario, many residential projects below a certain size do not legally require an architect – a licensed BCIN designer can handle them.
A building designer (BCIN licensed) can prepare permit drawings for low-rise residential projects within a defined scope: houses, additions, renovations, garden suites, and similar. For structural elements beyond a certain complexity, a structural engineer is required to review and stamp those portions of the drawings.
An engineer (P.Eng, licensed by Professional Engineers Ontario) provides structural, mechanical, or civil calculations and stamps drawings within their area of expertise. Many residential projects require both a building designer to prepare the architectural drawings and a structural engineer to confirm load-bearing elements.
Sandra and Johanna bring architectural training from Venezuela and understand how all three disciplines interact. We coordinate with licensed engineers and BCIN designers as required to produce complete, compliant permit packages.
Q: What does the Toronto building permit process look like for a renovation or addition?
The building permit process in Toronto begins with a complete application: architectural drawings showing the existing and proposed conditions, a site plan, any required structural drawings, and the applicable forms and fees. Incomplete applications are one of the most common causes of delays – the city returns them for revision and the timeline resets.
Once submitted, straightforward residential renovations and additions are typically reviewed in 20 to 30 business days. Projects that require zoning review, a minor variance, or heritage approval take longer – sometimes significantly longer, depending on the complexity and whether a Committee of Adjustment hearing is required.
During construction, the city requires inspections at specific stages: framing, insulation, rough-in plumbing and electrical, and final. We coordinate all required inspections as part of our project management process.
Q: How much does building design and permit drawing preparation cost in Toronto?
Design and permit drawing fees for Toronto residential projects vary significantly by project scope. For a straightforward addition or basement renovation, design fees typically run $5,000 to $15,000. A full house renovation or custom home project requiring comprehensive permit drawings can run $15,000 to $40,000+ depending on size and complexity.
These fees cover the drawings themselves, coordination with structural engineers where required, any revisions requested by the city during permit review, and attendance at inspections. Permit fees paid to the city are separate — typically $100 to $300 for simple work, and $10,000 to $30,000+ for a new home build.
Design fees are often the most cost-effective investment in a renovation. Drawings that are thorough and code-compliant from the start avoid the change orders, delays, and rework that incomplete planning produces.
Q: Can you prepare drawings for a garden suite or laneway house in Toronto?
Yes. Toronto’s garden suite and laneway housing programs have specific zoning permissions and design requirements that need to be understood before drawings are prepared. The city has pre-approved certain setbacks, heights, and footprint limits for these structures, and drawings need to reflect those constraints accurately.
We prepare the design and drawings for garden suite and laneway house projects, coordinated with a licensed BCIN designer or engineer who reviews and stamps for permit submission. We also handle the zoning analysis upfront – confirming whether your lot qualifies and what the maximum permitted size is – before any design fees are committed.
Garden suites and laneway houses are one of the most common projects we field questions about, and one of the areas where getting the drawings right the first time matters most. The city’s review process for these projects is active and detailed.
Q: What is the difference between building design and interior design?
Building design, in the Ontario regulatory context, refers specifically to the preparation of permit drawings that comply with the Ontario Building Code – the structural, spatial, and technical documentation required to get a building permit. It is a regulated activity requiring a BCIN licence or higher.
Interior design, as a regulated profession in Ontario, is practiced by Registered Interior Designers (ARIDO members) and involves space planning, material selection, and specifications. A Registered Interior Designer can prepare certain permit drawings for interior alterations, but their scope is different from a BCIN building designer.
In practice, most homeowners need someone who understands both – the spatial and aesthetic decisions (interior design) and the technical and code-compliant documentation (building design). Our architectural training covers both dimensions. We design spaces that are beautiful and buildable, and we prepare the technical drawings that turn those designs into approved permits.
Q: Do you work on projects outside the City of Toronto?
Yes. While our primary market is the City of Toronto and the inner GTA, we work on projects across the Greater Toronto Area including Mississauga, Markham, Richmond Hill, Vaughan, Brampton, and surrounding municipalities. Each municipality has its own zoning by-laws and permit procedures, and we review those requirements at the start of every project.
The Ontario Building Code applies province-wide, so the drawing standards and technical requirements are consistent. The differences between municipalities are primarily in zoning – permitted uses, setbacks, height limits, and coverage ratios – and in the permit review process and timelines.
Q: What projects do you typically prepare drawings for?
We prepare design and permit drawings for a range of residential projects in Toronto and the GTA: single-family home renovations and additions, basement finishing and underpinning, garden suites and laneway houses, kitchen and bathroom renovations requiring structural or plumbing changes, second suite additions, and custom home builds.
Every set of drawings we produce starts with a thorough understanding of the existing conditions – what the home is, how it’s built, what the zoning allows, and what the client is trying to achieve. We do not produce drawings that look good on paper but don’t reflect reality. The drawings need to be accurate, code-compliant, and buildable.
Q: How do you handle the structural engineering portions of permit drawings?
Structural engineering – the calculations and drawings required for load-bearing elements, beams, columns, foundations, and similar – requires a licensed Professional Engineer (P.Eng). We do not provide structural engineering ourselves.
What we do is coordinate the structural engineering as part of the permit drawing process. We work with licensed structural engineers who review the relevant portions of our drawings, provide the required calculations, and stamp the structural elements. This coordination is included in our design fee – you do not manage a separate engineering relationship.
The result is a complete permit package: architectural drawings prepared by us, structural drawings reviewed and stamped by a licensed engineer, and all required forms and documentation. One point of contact, one submission.

What Does a Building Designer Do in Toronto?
A building designer in Ontario prepares the permit drawings required under the Ontario Building Code for residential construction, renovation, and addition projects. This includes architectural drawings showing existing and proposed conditions, site plans, and coordination with structural engineers where required. In Ontario, permit drawings must be prepared or reviewed by a BCIN-licensed designer, a licensed engineer, or a licensed architect.
At Habitual Homes, we bring architectural training and hands-on construction experience to the drawing preparation process. Because we also build what we design, our drawings reflect how buildings actually go together – not just how they look in plan.
Building Permit Drawings for Toronto Renovations and Additions
Most meaningful renovation projects in Toronto — structural changes, additions, basement finishing, garden suites, second suites — require permit drawings before construction can begin. We prepare complete permit packages for these project types, coordinating with licensed structural engineers where required and managing the city review process through to approval.
Toronto’s permit review process returns incomplete applications — resetting the timeline. We prepare thorough, code-aware drawings from the start to minimize revision cycles and keep projects moving.
Garden Suite and Laneway House Design in Toronto
Toronto’s garden suite and laneway housing programs allow additional residential units on existing lots under specific zoning permissions. We prepare the design and permit drawings for garden suite and laneway house projects, coordinated with licensed BCIN designers or engineers for stamp and submission. We conduct zoning analysis at the start to confirm eligibility and maximum permitted size before any design fees are committed.
BCIN Licensing and How It Works
The Building Code Identification Number (BCIN) is the licence issued by the Ontario Ministry of Municipal Affairs and Housing to qualified building designers. It allows the holder to prepare permit drawings for low-rise residential projects within a defined scope. Sandra is currently preparing for the BCIN designer exams. In the interim, all permit drawings Habitual Homes produces are reviewed and stamped by a licensed BCIN designer or engineer.
