Planning to upgrade your backyard with a new patio or covered outdoor area? You’re not alone. Homeowners across Mid-Missouri are investing in beautiful, functional outdoor spaces that boost both comfort and property value. But before you break ground, there’s one important question you should ask: Do you need a permit to build a patio in Missouri?
The answer depends on a few key factors like size, structure type, and whether the patio is attached to your home. Knowing whether you need a patio permit in Missouri can help you avoid costly mistakes and stay on track with your project timeline. In this guide, we’ll break it all down for you, so you can move forward confidently with help from WestCo Outdoor Services, your trusted local outdoor services contractor in Jefferson City, Columbia, and surrounding areas.
Quick Answer – Do You Need a Permit to Build a Patio in Missouri?
Yes, you may need a permit to build a patio in Missouri, especially if it’s covered, attached to your home, includes electrical work, or exceeds certain size or height limits. Cities like Jefferson City and Columbia follow local building codes that can vary. To avoid costly mistakes, always check with your local building department, or hire a licensed contractor to handle the permits for you.
When Is a Permit Required?
Concrete or Paver Patios (Uncovered)
If your patio is flat, ground-level, and uncovered, you may not need a building permit, especially if it’s not physically attached to your home. That said, it must still comply with zoning rules such as:
- Property line setbacks
- Easement clearance
- Drainage requirements
In some neighborhoods or HOAs, design approval may be required even for simple ground-level pavers.
Covered Patios or Roof Structures
If you’re wondering “can I build a roof over my patio?”, the answer is yes, with the right materials, design, and permits.
In most areas, you do need a permit to build a patio cover in Missouri, particularly when the structure is attached or includes utilities. If you’re planning a covered patio, pergola, or roof extension, you’ll almost always need a permit, especially if it meets any of the following conditions:
- Attached to your home
- Includes electrical or lighting
- Exceeds 120 square feet
- Alters the structure of your roofline
Depending on your HOA, zoning district, or floodplain location, you may also need permission for a covered patio even if a building permit isn’t required.

What Happens If You Build Without a Permit?
Trying to skip the paperwork? That’s a risk not worth taking. Here’s what could happen if you build a patio without the required permit:
- Fines and penalties from your city or county
- Stop-work orders that delay or halt construction
- Forced removal of the structure at your own expense
- Issues when selling your home, including failed inspections or appraisal complications
