What Permits Are Needed to Build a Pergola in Denver? 2025 Guide

Planning to enhance your Denver backyard with a stylish and durable aluminum pergola? It's a fantastic investment in your home and lifestyle. But before construction begins, it's essential to understand the local regulations. A common question we get at Mile High Patio is: Do I need a permit to build an aluminum pergola in Denver?

The short answer, according to the City and County of Denver's official guidelines, is yes. Let's dive into the details of Denver's permit requirements for pergolas.

Why Does Denver Require Permits for Pergolas?

Permits might seem like extra paperwork, but they serve crucial purposes:

Safety: Permits ensure your pergola is designed and built to withstand Denver's specific weather conditions, including snow loads and high winds. This protects your family and your property.
Code Compliance: The permit process verifies that the structure meets current Denver Building and Zoning Codes regarding structural integrity, materials, height, size, and location on your property (setbacks).
Property Value: Permitted work adds legitimate value to your home and avoids potential issues during a future sale that unpermitted structures can cause.
Avoiding Penalties: Building without required permits can lead to stop-work orders, fines, or even mandated removal of the structure.

Denver Permit Requirements for Aluminum Pergolas:

Based on information from the City and County of Denver Community Planning and Development department:

Zoning Permit: This permit reviews the project's compliance with Denver's Zoning Code, including placement on the property (setbacks from property lines), height restrictions, and overall size allowances for accessory structures in your specific zone district.
Building Permit: This permit focuses on the structural aspects of the pergola, ensuring it meets the Denver Building Code requirements for safety, materials (like the aluminum components), footing specifications, connection details, and resistance to environmental loads (snow, wind).

Key Takeaway: Denver's official guidance indicates that all covered structures, which includes pergolas (regardless of whether they are attached to the house or freestanding), require both a zoning and a building permit.

What About Size or Attachment?

While regulations in some surrounding areas might have exemptions based on size (e.g., under 120 or 150 sq ft) or whether the structure is attached, Denver's rules for pergolas are more straightforward: if it's a pergola (a covered structure), it needs permits. Don't rely on general advice; stick to Denver's specific requirements.

Additional Permits That Might Be Needed:

Electrical Permit: If you plan to include integrated lighting, ceiling fans, or outlets in your aluminum pergola design.
Sewer Use and Drainage Permit (SUDP): May be required depending on your property's specific site conditions and how the project impacts drainage.
Demolition Permit: If an existing structure needs to be removed before the pergola can be built.

What's Involved in the Denver Permitting Process?

Obtaining permits typically involves:

Creating Detailed Plans: This includes a site plan showing property lines, existing structures, and the proposed pergola's location, dimensions, and setbacks. Structural drawings detailing footing design, post sizes, beam spans, connection methods, and materials are also required.
Online Application: Submitting the application and plans through Denver's e-permits portal (denvergov.org/epermits). This requires creating an account.
Plan Review: City officials review the submitted plans for compliance with zoning and building codes. They may request clarifications or revisions.
Fee Payment: Permit fees are required before the review process begins or permits are issued.
Permit Issuance: Once approved, the permits are issued electronically.
Inspections: Mandatory inspections are conducted by the city at various stages during construction (e.g., footing inspection before pouring concrete, framing inspection, final inspection) to ensure work matches the approved plans and meets code.
