If you’re planning to repair or restore a deck in the Denver area, it’s important to understand the city’s building and zoning requirements before you start. Denver has specific rules for residential decks, porches, patios, and other outdoor structures. Failing to follow these guidelines can lead to costly delays, rework, or even safety issues.
At Denver Deck Repair, we help homeowners connect with experienced professionals who understand the permitting process and how to ensure your project complies with local codes. But even if you’re hiring a contractor, it’s still smart to understand the basics yourself.
Here’s what you should know before you begin your deck repair or restoration project in Denver.

Permit Requirements for Deck Repair and Restoration
The need for permits depends on the scope and height of your deck project. Below is a general outline of when zoning or building permits are required in the City and County of Denver:
Zoning Permit Required:
- All uncovered decks that are 12 inches or higher off the ground.
Building Permit Required:
- Uncovered decks that are 30 inches or more above grade.
- All covered decks or structures, including porches, carports, pergolas, and patio covers.
Even if you’re simply replacing old boards or performing minor repairs, it’s a good idea to verify whether your work triggers a permit requirement—especially if you’re replacing structural components like beams, joists, or posts.
What You’ll Need to Apply for a Permit
If your deck project does require a permit, you’ll need to submit plans and documentation through Denver’s e-permits portal. Typically, this includes:
- Site Plan: A scale drawing that shows your property boundaries, existing structures, and the proposed location of the deck.
- Building Elevations: Side views of the proposed or existing structure that include height, railing details, and stair design.
- Construction Drawings: These should show footing depth, framing details, post and beam specs, connections to the home, and materials to be used.
If the deck is covered or enclosed, your application will also need to include roof span diagrams, wall section drawings, and possibly energy code compliance if insulation or permanent coverings are involved.
Important Considerations for Denver Deck Projects
In addition to standard permits, several other factors might affect your project:
Historic Properties:
If your home is in a designated historic district or is a landmark structure, you’ll need to obtain a Certificate of Appropriateness from the Landmark Preservation office before any permits can be issued.
Tree Protection:
If your project impacts the canopy or root zone of a street tree or tree on public property, coordination with Denver Forestry is required.
Drainage and Sewer Access:
You may need a Sewer Use & Drainage Permit (SUDP), especially if your deck is being rebuilt over or near a utility easement or sewer line.
Floodplain Regulations:
If your property lies within a designated flood zone, additional reviews may apply. This typically includes providing elevation data and demonstrating that the structure won’t interfere with floodwater flow.
Parkways and State Roads:
Properties along parkways or near CDOT-controlled roads may be subject to additional approvals or engineering reviews.
Should You Apply as a Homeowner or Hire a Contractor?
Denver allows homeowners to apply for permits themselves, but you’ll be responsible for ensuring all work meets city code and inspection requirements. If you’re not familiar with deck construction, hiring a licensed contractor can save time and reduce the risk of errors.
At Denver Deck Repair, we help connect homeowners with professionals who understand Denver’s permitting process and building requirements. The contractors in our network can often assist with drawing plans, applying for permits, and scheduling inspections—so you don’t have to manage it all yourself.
