We are a trusted deck builder in Toronto, Richmond Hill, Markham, and other nearby areas.
A strong deck starts long before construction begins. In Ontario, accurate permit drawings can determine whether your application moves smoothly or gets delayed by missing details, code concerns, and revision requests.
Homeowners generally have three options: hire a specialized deck permit service, work with an architect, or ask a deck contractor to coordinate the drawings. Each option offers a different balance of cost, design expertise, approval support, and construction knowledge. The right choice depends on the deck’s complexity, your budget, and whether you need drawings only or a complete design and build service.
This guide explains what each professional provides, how their fees compare, and which option is likely to suit your Ontario deck project.
Key Takeaways
- Deck permit services specialize in code-compliant drawings and typically cost less than architects while offering faster turnaround times
- Architects provide custom design expertise but are best suited for complex or high-end deck projects where unique features justify the higher cost
- Deck contractors can prepare drawings if they have BCIN certification, often bundling this service with construction for a complete package
Understanding Permit Drawing Requirements in Ontario
In Ontario, deck permit drawings must follow the Ontario Building Code and show technical details like footings, framing, guards, and stairs. Getting these drawings right the first time helps avoid deficiency letters, delays, and failed inspections.
Ontario Building Code Basics
The Ontario Building Code (OBC) sets the rules for deck construction across the province. Most residential decks fall under Part 9 of the code, which covers housing and small buildings.
The code requires guards on any deck more than 600 mm (about 24 inches) above grade. These guards must be at least 1,070 mm high and built so a 100 mm sphere cannot pass through. Stairs need handrails if they have more than three risers.
Footings must extend below the frost line, typically 1,200 mm deep in most of Ontario. The exact depth can vary by municipality, so it is important to check local requirements.
Drawings must show all these details, including a site plan, foundation plan, framing plan, and elevation views. Most municipalities also require guard and stair details with specific dimensions.
Why Permits Matter for Homeowners
You are legally responsible for obtaining the permit, even if you hire a contractor. Most professional builders handle the application for you, but the permit remains in your name.
Building without a permit can result in stop-work orders and fines. In some cases, you may need to remove the deck and start over with proper permits.
Permits also help maintain your home’s value. When selling, buyers and their lawyers often ask for permits. A deck built without one can complicate a sale or require last-minute legalization. Insurance companies may also deny claims for unpermitted structures.
The permit process includes inspections at key stages to catch problems early.
Common Mistakes on Permit Drawings
Missing dimensions are a common reason drawings get rejected. Every joist, beam, and post spacing needs to be marked clearly.
Incomplete site plans also cause delays. The deck’s location relative to property lines, the house, and other structures must be shown, with setback distances marked and meeting zoning bylaws.
Guard details are sometimes missing or incorrect. Inspectors want to see baluster spacing, rail heights, and connection methods. A simple sketch is not sufficient.
Footing details may be missed or drawn incorrectly. Drawings must show footing size, depth, and reinforcement. For decks on slopes or unusual soil, engineered drawings with a stamp may be required.
Role of a Deck Permit Service
Deck permit services specialize in preparing building permit drawings and handling municipal submissions for deck projects in Ontario. These companies employ BCIN-certified designers who focus on residential permit work, and their fees typically fall between what you would pay an architect and what a contractor might charge for the same drawings.
Services Typically Provided
A deck permit service prepares technical drawings required by the municipality. This includes site plans with property lines and setbacks, foundation plans with footing locations and depths, framing plans with joist spacing and beam sizes, and elevation drawings showing guardrail heights and stair details.
Most services also handle the zoning review to confirm compliance with local bylaws. They prepare permit application forms and submit everything to your city or town.
If the municipality issues a deficiency letter, the permit service revises the drawings and resubmits them. Some companies include one or two rounds of revisions in their base price, while others charge extra for each resubmission.
Some permit services offer consultation during construction if questions arise about the approved drawings. They do not provide construction supervision but can clarify technical details.
Pros and Cons for Homeowners
Pros:
- Lower cost than hiring an architect for the same work
- Fast turnaround time (usually 3-7 business days for drawings)
- Staff who specialize in Ontario deck permits
- Familiarity with local municipal requirements and common approval issues
- Some services offer guaranteed approval or free revisions
Cons:
- Limited design input compared to an architect
- No construction oversight or site visits
- Not suited for complex structural issues beyond standard deck construction
- Some services provide minimal customer support after permit approval
How Fees Are Structured
Most deck permit services charge flat fees based on deck size and complexity. A basic ground-level deck under 200 square feet might cost $400-$600 for permit drawings. Elevated decks or multi-level designs typically cost $700-$1,200.
The flat fee usually includes the drawing package, one zoning review, municipal submission, and one round of revisions if needed. Rush services cost extra (typically $150-$300 more for 24-48 hour turnaround).
Some companies charge hourly rates instead, ranging from $75-$125 per hour. This can work for unusual projects where the scope is unclear. Flat fees are common for straightforward deck permits since the total cost is known upfront.
What Architects Bring to the Table
Architects offer professional design expertise and regulatory knowledge, but their services come with premium pricing that may not match the scope of a typical deck project.
Expertise in Design and Compliance
Architects hold professional designations and carry liability insurance for their design work. They understand building codes, zoning requirements, and structural principles. Architects are valuable on complex builds that integrate with significant home renovations or unique structural challenges.
Their training covers comprehensive building design, so they can handle situations where decks connect to second-story additions, require custom engineering, or need to match specific architectural styles. Architects also know how to navigate municipal approval processes and can represent your project during committee reviews if needed.
Their legal authority to stamp drawings and take professional responsibility for the design can be important if your municipality has strict requirements about who can submit plans.
Cost Considerations
Architect fees for deck drawings typically range from $1,500 to $4,000 or more, depending on project complexity and the firm’s rates. This can be a substantial cost when your entire deck budget might be $15,000 to $25,000.
Most architects charge hourly rates ($150-$300 per hour) or fixed fees based on project scope. For simple rectangular decks with standard railings and stairs, this investment is rarely necessary.
The pricing reflects their education, licensing, and insurance costs. You are paying for credentials that may exceed your project’s requirements.
Limitations When Working With Small Projects
Many architectural firms are not interested in deck-only projects. It can be challenging to find architects willing to take on small jobs because they do not fit well into typical workflow or fee structures.
Architects often prioritize whole-home designs, additions, and commercial work. A standalone deck drawing might take them a few hours to complete, but the administrative overhead and liability are similar to larger projects.
Some firms will accept deck projects only as add-ons to larger contracts. Others might assign them to junior staff. Response times can also be slower since deck permits are not their primary focus.
How Deck Contractors Approach Permit Drawings
Most deck contractors either prepare basic permit drawings in-house or work with a third-party service to handle the paperwork. The quality and detail vary depending on the contractor’s experience, the municipality’s requirements, and whether they have a BCIN-certified designer on staff.
Typical Process for Plans and Approvals
When you hire a deck contractor, they usually start by measuring your property and discussing your design preferences. From there, they create or commission a set of drawings that show the deck layout, framing plan, and key structural details.
The contractor then submits these drawings to your municipality along with the permit application. In most GTA municipalities, you can expect a review period of 10 to 20 business days. Permit fees typically range from $180 to $550 CAD depending on the deck size and location.
Once the permit is approved, the contractor schedules construction and coordinates required inspections. Most municipalities require at least one inspection before the deck is finished, often at the footing stage or after framing is complete.
Level of Detail in Contractor Drawings
Contractor-prepared drawings tend to focus on the basics: footings, beam sizes, joist spacing, guardrail heights, and stair dimensions. These plans are usually straightforward and practical, designed to get the permit approved.
However, the level of detail can vary. Some contractors provide clear, code-compliant plans with proper annotations and calculations. Others submit minimal sketches that may trigger deficiency letters or requests for additional information from the building department.
The quality often depends on how familiar the contractor is with your local building department’s expectations. Experienced contractors know what reviewers want to see and can streamline the process.
In-House vs. Outsourced Drawing Preparation
Many smaller deck contractors outsource their permit drawings to specialized services or designers. This approach costs them around $300 to $600 per project but helps ensure the drawings meet municipal standards and include all required details.
Larger contractors with steady project volume sometimes keep a BCIN-certified designer on staff. This allows them to control the drawing process, make quick revisions, and avoid delays.
Both approaches are used, but outsourcing is more common. It lets contractors focus on building while leaving the technical paperwork to someone who handles permits full-time.
Comparing Costs: Deck Permit Services, Architects, and Contractors
The price gap between these three options reflects what you are actually buying. A deck permit service might charge $400 to $800 for basic drawings, while an architect could bill $1,500 to $3,000 for the same deck, and a contractor often bundles permit work into their quote.
Budgeting for Permit Drawings
Deck permit services charge flat fees for drawing packages that meet building department requirements. In most Ontario cities, you will pay between $400 and $800 for a standard residential deck under 200 square feet. These services focus on permit approval, not design flourishes.
Architects bill differently. Most charge hourly rates between $150 and $250, which can push a simple deck permit package to $1,500 or higher. The higher cost reflects their professional designation and liability insurance.
Deck contractors handle this work in one of two ways. Some include permit drawings in their build quote at no separate charge. Others add $300 to $600 to cover their time and any third-party drawing services they use. Contractors tie permit work directly to construction, so they are motivated to get approval quickly.
Hidden Costs to Watch Out For
Engineering stamps add $300 to $800 when your deck needs structural review. This is required for elevated decks, large spans, or challenging soil conditions. Permit fees do not include the engineer’s letter you might need.
Resubmission fees can occur if your drawings are rejected and need revisions. Some permit services charge $150 to $300 for corrections. Architects may bill hourly for minor tweaks.
Plan review delays can cost money indirectly. If your contractor is waiting on permit approval, they might move to another job. Rescheduling crews can delay your project by weeks, especially during busy summer months.
Quality and Accuracy: Who Gets It Right?
Getting your drawings right the first time helps avoid delays and extra fees. The difference between professionals often comes down to their knowledge of Ontario Building Code requirements and municipal expectations.
Ensuring Code Compliance
Many deck plans look appealing but miss critical code requirements. A dedicated deck permit service typically employs BCIN-certified designers who work with building codes daily. They know that guard heights must be 1070mm minimum, stair risers cannot vary more than 6mm, and when frost-protected footings are required.
Architects have strong technical knowledge but may not specialize in residential deck details. They are suited for complex projects but may over-engineer simpler decks.
Deck contractors vary. Some have years of experience and produce solid drawings. Others submit sketches that get rejected for missing structural details, footing sizes, or proper dimensions. It is important to check if a contractor has BCIN certification or works with someone who does.
The best option depends on your deck’s complexity. Standard rectangular decks under 200 square feet often work well with a permit service. Multi-level designs with custom features may need an architect’s expertise.
Avoiding Permit Rejections
Most permit rejections result from missing information. Municipalities want to see specific details: ledger board attachment schedules, beam span calculations, post-to-beam connections, and guard infill spacing.
A permit service knows what each municipality expects. For example, Toronto requires different drawing details than Oakville or Ottawa. They submit complete packages the first time.
Contractors who do not regularly prepare drawings may forget required details. Plans are sometimes rejected for missing frost depth notes, unclear footing sizes, or no guardrail specifications. Each resubmission can add two to three weeks to your timeline.
The deficiency letter indicates missing or incomplete information. If you receive one asking for basic information like dimensions or materials, your drawings may not have been prepared by someone familiar with permit submissions.
Timeline Expectations for Deck Permits
Most Ontario municipalities process simple deck permits in 10 business days to 6 weeks. The total timeline from application to approval depends on how complete your drawings are and whether your municipality offers faster processing options.
Typical Turnaround Times
Simple residential deck permits typically take 10 to 15 business days in many Ontario municipalities. Some cities offer over-the-counter permits for basic decks that meet standard criteria, which can be approved the same day or within a few business days.
Complex projects take longer. Decks with custom features, unusual heights, or challenging site conditions may require 3 to 6 weeks for review. Toronto and larger municipalities often take longer due to higher application volumes.
The permit review is one part of your total project timeline. Most homeowners should plan for 5 to 12 weeks from signing a contract to having a finished deck, including permit processing, material ordering, construction, and final inspection.
Factors That Delay Approval
Incomplete or incorrect drawings are the main cause of delays. When the building department identifies problems, they send a deficiency letter. The review process resets when you resubmit, adding 2 to 4 weeks to your timeline.
Common issues include unclear footing depths, missing guard rail specifications, or incomplete site plans. Applications may be returned multiple times when drawings are not prepared by someone familiar with the process.
Municipal workload also affects processing times. Summer is peak season for deck permits, so reviews take longer in June and July. Winter applications often move faster due to lower submission volumes.
Submitting complete, professional drawings during off-peak months can help you achieve faster approval.
Working With Local Building Officials
Building officials review your drawings before approval and inspect your deck at specific stages during construction. Clear communication with inspectors helps avoid delays and ensures compliance with the Ontario Building Code.
Navigating Inspections and Reviews
Your deck permit drawings are reviewed by a building inspector before approval. Most Ontario municipalities complete this review in 10 to 20 business days. The inspector checks that your plans meet Ontario Building Code requirements for structural integrity, guardrail height, and attachment methods.
If the inspector finds issues, you will receive a deficiency letter listing specific problems to address before approval.
Once construction starts, your work must pass inspections at key stages. The inspector typically needs to see the footing excavation before concrete is poured and inspects the framing before decking boards are installed. Permit drawings must be on site during every inspection.
Communicating Changes During Construction
Construction may require adjustments. For example, you might discover that your house rim joist needs reinforcement or that soil conditions require deeper footings.
Contact your building department before making changes to permitted drawings. Small modifications may need inspector approval on site, while larger changes require revised drawings and a formal permit amendment.
Keep records of all conversations with building officials, noting the inspector’s name, date, and what was approved or requested. This documentation can be helpful if questions arise later.
Choosing the Best Solution for Your Deck Project
The best option depends on your deck’s complexity and your comfort level with the process.
For simple ground-level decks under 24 inches high, homeowners can often obtain permits using basic drawings. If the project is straightforward, this can save money, but you must still submit scaled drawings showing footings, framing, guards, and stairs.
A specialized deck permit service works well for most residential deck projects. These services are typically less expensive than architects, are familiar with deck-specific code requirements, and are usually quicker. Permit-ready drawings can sometimes be delivered in under a week.
An architect is appropriate if your deck is part of a larger renovation, involves structural changes to your house, or includes custom features that require engineering stamps. This is generally the most expensive option for a standalone deck.
Your deck contractor may offer permit drawings as part of their service. This can simplify coordination, but ensure they have a BCIN-certified designer on staff.
Before deciding, consider the following:
- Does the person or service have BCIN certification?
- How long will it take to get drawings ready?
- What is included in the price (site plan, structural details, revisions)?
- Will they handle municipal submissions and deficiency responses?
Most homeowners building elevated or attached decks use a dedicated permit service, which balances cost, speed, and expertise for typical projects.
Frequently Asked Questions
These answers cover common questions about deck permit drawings, professional services, costs, applications, and revisions in Ontario.
Do I actually need permit drawings for my deck in Ontario, and what does the building department usually want to see?
A permit is generally required when a deck exceeds 10 square metres, rises more than 61 centimetres above grade, or attaches to the house. Requirements vary by municipality. Drawings commonly include a site plan, floor plan, elevations, foundation details, framing dimensions, guards, stairs, setbacks, and connection methods.
When is it worth hiring an architect for deck permit drawings, and when is that overkill?
An architect may be worthwhile for a complex, multi-level, or highly customized deck, especially when it connects to a major renovation or involves unusual structural conditions. For a standard rectangular backyard deck, a BCIN-certified designer or permit service is usually more practical and affordable.
What can a deck permit service provide that a deck contractor cannot, and vice versa?
A permit service specializes in code-compliant drawings, zoning reviews, applications, and deficiency responses. A deck contractor focuses on construction, materials, scheduling, and inspections. Some contractors offer both services, but confirm whether a qualified BCIN designer prepares or reviews the drawings.
Can my deck contractor submit the permit application for me, or do I need to be the applicant as the homeowner?
Your contractor can usually submit the permit application with your authorization. You may also apply yourself. The homeowner remains responsible for ensuring the required permit is obtained and that the completed deck follows the approved drawings and applicable building requirements.
Who is responsible if the permit drawings are wrong and the inspector asks for revisions or a redesign?
Responsibility depends on your agreement with the drawing provider. A permit service, architect, or contractor should correct mistakes caused by their work. Ask in advance whether revisions, deficiency responses, resubmissions, and additional municipal requests are included in the quoted price.
How much do permit drawings typically cost in Ontario, and what should be included so there are no surprises later?
Permit drawings commonly cost about $500 to $1,200, depending on deck size and complexity. The quote should explain whether it includes site measurements, zoning review, structural details, application support, and revisions. Engineering services and municipal permit fees may be charged separately.
