It’s every homeowner’s dream to have their own deck without the unwanted paperwork and hassle, but is it possible? Can you build a deck without a permit?

Quick answer: Yes.

But what size deck can you build without a permit? In this article, we’ll find out the answer.

Let’s look at the size restrictions, design guidelines, and everything you need to know to avoid permits and still follow the city rules.

What Size Deck Can I Build Without Permit

The biggest size of deck that can be built without a permit is 200 square feet. However, deck design and height should also be considered when planning permit-free projects.

According to the International Residential Code (IRC), decks won’t require a permit if they:

  • Are less than 30 inches above ground
  • Not attached to the home
  • Not located near the main exit doors

Consider freestanding or floating decks located near either a garage or bedroom door to keep the project permit-free.

However, the building codes and regulations of local governments come before the IRC, so check the state rules before starting a deck project.

How to Ensure Your Permit-Free Deck is Within Code

Going permit-free doesn’t mean violating local building codes. Build a deck hassle-free with these tips:

1. Use Permit-Exempt Smart Design Choices.

To avoid permits, keep the design simple and lightweight. It’s a good idea to opt for a single-level deck with an open design.

Additionally, use lightweight deck materials. Composite, aluminum, and PVC are the top picks.

Avoid adding permanent fixtures, like roof, pergola, or plumbing and electrical systems. Built-in seats and planters add to the total weight, so skip them to ensure that the deck stays within weight limits.

2. Obtain Planning Permission When Necessary.

A planning permission is a permit that ensures compliance with setback requirements and zoning laws.

Securing this permit is necessary if the deck is close to property lines and goes beyond the allowed lot coverage.

3. Prepare a Site Plan.

A site plan is one of the deck permit requirements, but it’s also a good tool for permit-free projects.

For one, it clearly outlines your deck design, showing the building department the size, dimensions, and exact location in relation to your home.

Second, it gives a clear visual of the project and can serve as a construction roadmap that will guide the construction team and keep the project on track.

4. Keep Construction-Related Documents for Future Reference.

Always keep a copy of important documents, like site plans, deck plans, and planning permission. Additionally, save all correspondence with local authorities.

These records not only serve as proof of compliance but also ensure smooth inspections and protect you from possible disputes in the future.

Deck Permit FAQs

Do You Need a Permit to Repair or Replace an Existing Deck?

It depends on the extent of repair and replacement. If there are major changes like deck expansion and addition of heavy permanent features, then you will need to secure a permit.

Do You Need a Permit for a Floating Deck?

It depends. If the floating deck is within the criteria for permit exemption, there’s no need to obtain permits.

Disclaimer: Deck permit requirements vary depending on the city, so make sure to verify the rules with the local authorities.
