It's a fair question—and one that’s easy to skip right past. Maybe you're picturing a cozy space for grilling and late-night lounging. Or maybe you've already picked out the stain color. Either way, do you need a permit to build a deck? In a lot of cases, yes. But the details can get muddy fast. Before you start building your deck, it's worth knowing what's required in your area—and what could go wrong if you don't bother.
Why Do You Need a Permit To Build a Deck?
If your deck is attached to the house or built a couple feet off the ground, you'll likely need a permit. Most cities have rules about this, and they usually come into play once a deck reaches a certain height, often around 30 inches, or when it connects directly to the home.
There's a reason for this. A deck needs to support weight, stay level over time, and meet basic safety standards. Building codes, which are often based on the International Residential Code, help make sure that happens. Railings, stairs, footings, and how far your deck sits from the property line all come into play.
Deck permit requirements aren't just red tape. They catch things that could turn into bigger issues later. So before you start building, it's worth finding out what your local code requires. It might be more straightforward than you think.
When You Might Not Need a Permit
Not every deck project needs a permit. If you're building something small, low to the ground, and not attached to your house, you might be in the clear. Many cities don't require a permit for freestanding platforms under 30 inches or so and below a specific square footage.
Note that some areas are stricter than others, especially if your home is in a flood zone, on a slope, or part of a homeowner's association. When in doubt, ask. It's easier than undoing work later.
How To Find Out What Your Area Requires
Every city, county, and township sets its own rules, so the only way to know what applies to your project is to go straight to the source. That usually means checking your local building department's website or giving them a call. Some cities even have online tools where you can plug in your address and get a list of requirements.
Be ready with the basics: how high your deck will be, where it'll sit on your property, and whether it's attached to your house. If you're not sure how to answer those questions, a contractor or handyman can help you figure it out.

What Happens if You Build a Deck Without a Permit?
Skipping the permit might seem harmless, especially if your deck "doesn't look that big" or you're doing the work yourself. But if a permit is required and you build without one, the consequences can be real. You could get hit with fines, be forced to stop construction, or even have to take the deck down entirely.
And the problems don't always show up right away. You might get through the build just fine, only to run into trouble when you try to sell your home. Unpermitted work can hold up a sale, lead to failed inspections, or cause issues with your homeowner's insurance.
Bottom line: Building a deck without a permit is not worth the risk. Getting the permit may take a little time upfront, but it can save you a lot of time and money later on.
DIY vs. Hiring a Pro: Factors To Consider
Building a deck yourself can be a rewarding project, if you've got the time, tools, and experience. But permits, inspections, and local codes tend to complicate things fast. What starts as a weekend build can stretch into weeks if you hit snags with paperwork or get something wrong that needs to be redone.
Hiring a professional means those details don't fall on your shoulders. A pro knows what the local rules are, how to pull permits, and how to build to code the first time. They can also schedule inspections, handle adjustments, and make sure everything passes without surprises.
At Mr. Handyman, we've built and repaired a lot of decks, and we've seen what happens when DIY plans go sideways. If you want a smooth process and a finished deck that's safe, solid, and up to code, hiring a pro is the way to go.
