Deck Permits in Newmarket: What Homeowners Need to Know

September 5, 2025

If you’re planning a new deck this year, understanding deck permits in Newmarket is just as important as choosing materials or design. Many homeowners are surprised to learn that a deck project can’t move forward without the right approvals. The Town of Newmarket has specific rules, and skipping this step can mean costly fines or even being forced to remove your deck.

This guide explains when you need a permit, what the process looks like, and how XP Decking can make sure your project is safe, legal, and ready to enjoy.

Why Do You Need a Deck Permit in Newmarket?

Some homeowners wonder why permits are required at all. After all, a deck feels like a personal backyard project. The truth is, a deck is a structural addition to your home and affects not just your property but also neighbouring lots.

Permits are enforced to:

Ensure decks are structurally sound and safe for families
Maintain compliance with zoning setbacks and property boundaries
Verify railings, stairs, and guards meet the Ontario Building Code
Protect homeowners from liability or insurance issues
Avoid complications during future resale of your property

Skipping a permit might seem like a shortcut, but it can result in costly penalties or even a forced deck removal. Following the rules protects your investment and peace of mind.

When a Deck Permit Is Required in Newmarket

The Town has clear criteria for when you need to apply for a permit. In general, you’ll need one if your deck is:

More than 0.6m (2 feet) above grade
Attached to your house
Built with a roof, covering, or pergola
Designed with stairs, railings, or guards

Smaller, ground-level platforms under 0.6m might not need a permit, but they must still meet zoning rules like setbacks and lot coverage. For these, our ground deck installation service ensures compliance without surprises.

Remember: even if a permit isn’t required, the deck must always be built safely and follow zoning by-laws.

The Step-by-Step Deck Permit Process

Applying for deck permits in Newmarket involves several stages. Knowing them ahead of time can help you avoid delays.

1. Zoning Review

The Town first checks whether your deck complies with zoning by-laws. This includes setbacks from property lines, lot coverage, and privacy screen restrictions.

2. Prepare Drawings

You’ll need to submit detailed drawings, including:

Site plan showing location and setbacks
Floor plan with deck dimensions
Elevations showing height above grade
Cross-sections with joist and beam details

3. Submit Application

The application package includes your drawings, forms, and permit fees (typically $180–$200).

4. Permit Approval

Once submitted, the Town reviews the documents. Processing usually takes 10–20 business days, but it may be longer during peak spring and summer months.

5. Post Your Permit

After approval, you’ll receive a permit card. This must be displayed on-site during construction.

6. Schedule Inspections

Inspections are required at multiple stages (footings, framing, final build). Only once you’ve passed the final inspection can the deck be considered complete.

Common Permit Requirements in Newmarket

When preparing your application for deck permits in Newmarket, expect to include:

Two complete sets of drawings
Footing and framing details sized according to code
Guardrail and stair details meeting the Ontario Building Code or engineered specs
Site plan confirming setbacks and coverage
Application forms and associated fees

Optional features like benches, lighting, or waterproof membranes should also be identified. At XP Decking, we handle all of these extras, including deck railing and benches and deck lighting.

How Long Does It Take to Get a Deck Permit?

Timing depends on how complete your application is and how busy the Town is. In Newmarket, permits are generally issued in 10–20 business days.

Spring and early summer are peak times for applications. To avoid delays, it’s best to submit early or start your project planning in the fall or winter. Having accurate drawings prepared by professionals like XP Decking also ensures fewer back-and-forth requests from reviewers.

The Inspection Process Explained

A deck project isn’t complete until all inspections are passed. Inspections confirm your deck has been built exactly as approved.

Typical inspections include:

Footing inspection before concrete is poured
Framing inspection after beams and joists are installed
Final inspection once guards, stairs, and finishes are completed

Failing to schedule inspections can void your permit, so always plan ahead.

Benefits of Following the Permit Process

Although some homeowners see the permit process as an extra hassle, there are clear benefits to doing things by the book.

Safety and durability: Code-compliant decks are built to handle Ontario’s harsh winters and heavy snow loads.
Legal protection: Proper permits protect you against complaints or disputes.
Resale value: Buyers are reassured when decks are approved by the Town.
Peace of mind: You can enjoy your outdoor space without worrying about future issues.

When viewed this way, getting deck permits in Newmarket is not a burden but an investment in your property.
