Once you pick your deck design and set your budget, you might think it’s time to buy materials and start building. But before you begin, it’s essential to pause and ask, “Do you need a permit to build your deck?” In most cases, the answer is yes. Deck construction usually needs a building or zoning permit. Rules can change based on where you live. Check with your local authorities first. This ensures your project meets code and safety standards before you start.
Building rules vary by location. You usually need a permit for projects that change your home’s structure, size, plumbing, or electrical systems. Since decks are often attached to the house, you usually need a building permit. Sometimes, a zoning permit is also required for new or replacement decks. In some cases, small, low decks under 200 square feet may not need a permit. Yet, local rules will determine this. Before you build, check with your local building department to find out what is needed. If you’re managing the project, know the permitting process and code requirements. When hiring a contractor, they usually handle the permits. Yet, it’s smart to check that all regulations are followed correctly.
Why do you need a building permit?
Most decks connect to a home’s main structure and often exceed size or height limits. So, a building permit is usually needed before starting construction. Always confirm local code requirements to ensure your project meets all regulations.
Building permits help make sure that construction meets local safety and zoning rules. This protects both current residents and future occupants. Codes change with regional conditions. What’s needed for a coastal Florida home is very different from a mountain property in Colorado. Local authorities issue permits to help keep structures safe and strong in different areas.
Building codes help keep people safe. They also protect homeowners in case of accidents. Insurance companies usually need proof that your project meets code. Homeowners’ associations often need the same. Failing to secure the proper permits can lead to fines or coverage issues down the line.
When you sell your home, you must disclose any unpermitted work. You also need to show proof of permits for completed projects. Homes with unpermitted work may have lower market value. Many lenders might not offer financing until these issues are fixed.
Some outdoor home improvement projects might need a building permit. It depends on their size and how they affect your property.
- Balconies
- Patios
- New roofing
- Sheds
Permit rules help keep you safe and ensure you follow local laws. They also help you avoid penalties from city authorities.
What happens if you don’t get a building permit?
Building a deck without the right permits can have serious effects. You might face fines, legal issues, or even be ordered to take down the deck. Local authorities usually find unpermitted work during inspections, property assessments, or neighbor reports. So, it’s hard to miss.
Homeowners who skip permits and ignore inspection standards might face big financial risks. If faulty construction leads to damage or injury, the builders are personally liable. Also, insurance companies usually deny claims for projects done without permits.
If unpermitted work is hidden until selling, the homeowner must inform buyers. They must also list the property “as is.” This can make getting a mortgage harder. You usually need retroactive permits and inspections before the sale can move forward.
Do you need a permit if you hire a contractor?
Licensed contractors must get permits for deck construction. They manage the application and ensure the project meets local building codes and rules.
Check reviews. Choose a licensed contractor. They should follow local codes to avoid future problems. If a contractor skips getting the right permits, they could be liable for damage or poor work. So, it’s important to check that they follow all the steps properly.
How to get a building permit
In Canada, local city or county offices manage building permits. They do this through their zoning or building departments. The application steps can vary by area or project type. Yet, the process is simple and easy to follow.
If you’re building your deck, you need to get the right permit. This means visiting your local building or zoning office to apply. It’s a good idea to reach out to them first. This way, you can check what documents or plans you need. It helps ensure a smooth approval process.
- Building and/or zoning permit application
- Two sets of construction plans
- Site plans
- Building and/or zoning permit fee
- Contractors must bring copies of their licenses
After you submit, the local building department will review your application and plans. They will then decide if they approve of them. The process typically takes anywhere from a few weeks to about a month.
For small projects, you usually don’t need detailed blueprints. An outline of the design, size, and materials is often enough. New builds, like decks, often need complete construction and site plans. These plans ensure they follow property boundaries and zoning rules.
How to create deck plans for permits.
The building department usually needs scaled deck drawings. This helps them understand your project’s scope and details.
At small, you need to provide a framing or overhead plan. Sometimes, an elevation drawing is also needed. This drawing shows the deck’s front or side to illustrate its height and structure.
Each deck plan should include:
- Project scope: location, size, and spacing of footings, beams, and joists
- Installation notes: for footings, railings, stairs, and ledger board
- Materials: for framing, decking, railing, hardware, and fasteners
You can make deck plans using digital design software or by sketching them on graph paper. It all depends on what you prefer and how complex the project is.
How to create site plans
Along with your deck design, a site plan is required to show how the structure fits on your property. You can make one using your own measurements or a professional survey. Check with your local building office to see if hand-drawn plans are okay.
Site plans should include:
- Existing property lines
- The home’s location and size
- Distances from each side of the deck to the property line.
- Distances from the deck to existing structures and landscaping elements.
Adding a deck enhances your home’s value and creates a relaxing outdoor space to enjoy. Building a deck can be a fun DIY project. But remember, most deck builds need permits before you start.

- Please submit two sets of your deck plans. Include scaled drawings and a brief overview of framing, materials, and installation methods. It’s possible to create these plans yourself, but it’s usually better to have a contractor do them. This is true even if you plan to build the deck yourself.
- Submit a site plan showing where your deck will sit in relation to property boundaries. If you don’t have one, check with your local building department – they may have a copy. Otherwise, you must measure your property or get a professional survey. This ensures the design follows zoning rules.
