Introduction 

Building a deck is an excellent way to enhance your outdoor space, but one important question is, “Do I need a permit to build a deck in Spokane?” The answer is often yes. Local regulations, especially those specific to the heavy snow loads in Spokane, Washington, make obtaining a deck permit essential. At Pacific Northwest Decks, we specialize in guiding homeowners through the entire permitting process to ensure safety, compliance, and peace of mind. In this blog post, we’ll cover why permits are required, how to obtain them, and what happens if you build without one.

Why You Need a Building Permit for Deck Construction 

Ensures Safety and Compliance

The main reason for getting a permit is to ensure that your deck complies with Spokane deck regulations and safety codes. Building codes exist to make sure that structures like decks can withstand environmental stressors like heavy snowfall, which is common in Spokane.

Key compliance requirements include:

  • Footings must be at least 2 feet deep to reach below the frost line.
  • Railings must be 36 inches tall if the deck height exceeds 32 inches.
  • Stairs with more than 7 steps need middle support to prevent sagging.

Permits ensure that all these aspects are checked and approved, preventing potential hazards. If you’re planning a deck build, take a look at our guide on How to Build a Deck for more insight.

Protects Against Faulty Construction

Permits are a critical safety measure to protect against poor construction. The process requires detailed deck plans, which Spokane’s local building authorities review for compliance. Proper review catches potential issues, such as inadequate footing depth, missing stair support, or undersized joists, before they turn into safety risks.

At Pacific Northwest Decks, we’ve assisted many homeowners in Spokane with their deck permit applications, ensuring their projects meet Spokane’s deck building regulations.

Helps Maintain Property Value

Building your deck with the correct Spokane deck permits helps maintain and even enhance your property’s value. When you decide to sell, having a permit in place assures potential buyers that the deck was built to code. It also makes the inspection process smoother, avoiding potential issues that could slow down or derail the sale.

When Is a Deck Building Permit Required?

Varies by Location and Deck Size

Permit requirements vary based on local regulations and the size of your deck. In Spokane, the following generally require a permit:

  • Decks taller than 32 inches off the ground.
  • Decks larger than 200 square feet.
  • Decks with stairs, railings, or other safety features.

Even for lower-level decks, it’s always best to confirm with the local building department to ensure compliance with Spokane deck regulations.

Typically Required for Structures Over a Certain Height or Size

If your deck exceeds a certain height or size, a permit is typically required. This ensures that the deck meets critical safety standards, such as railing height and stair stability. For example, decks over 32 inches must have railings at least 36 inches tall, while decks with longer staircases need middle supports.

Potential Consequences of Building a Deck Without a Permit 

Fines and Penalties

Building without a permit can lead to fines and additional permit fees. However, the biggest cost often comes from having to modify or rebuild the deck to comply with Spokane deck regulations. In some cases, entire decks have had to be removed and rebuilt, doubling the cost.

Difficulty Selling or Insuring Your Home

Homeowners in Spokane have reported that insurance companies are using drones to inspect properties. If they discover an unpermitted deck, coverage could be denied, or you could be required to bring the deck up to code to maintain insurance. Proper permitting helps prevent these complications when selling or insuring your home.

Safety Risks for Yourself and Others

Building a deck without a permit increases safety risks. Unpermitted decks may lack proper support, railing height, or structural stability, potentially leading to accidents. Ensuring that your deck meets Spokane’s safety standards protects everyone who uses it.

Unlicensed Contractors & Permit Avoidance

If your contractor suggests bypassing the permitting process, it could be a warning sign. They might not have the proper licenses or insurance, or they could be trying to cut corners. Always verify that your contractor is licensed and committed to obtaining the necessary permits.

Real-Life Case Study: Helping a Homeowner Build His Own Deck

Recently, we worked with a Spokane homeowner who wanted to build a 1,700-square-foot deck himself. We guided him through the permit application, provided building tips, and helped him save time. This experience shows how we support homeowners through every step of the process.

Rebuilding a Deck After Unpermitted and Unsafe Construction

This picture showcases a newly completed deck that I built for a homeowner after a troubling experience with an unlicensed contractor. Initially, the homeowner hired a contractor who failed to pull the required permit and attached the deck unsafely to a brick wall, violating building codes. The homeowner received a report from an inspector indicating serious safety risks, but the original contractor refused to provide guidance on how to fix the issues. After the inspection, it was clear that the entire deck needed to be demolished and rebuilt properly. Unfortunately, this meant the homeowner had to pay for a second deck. This story serves as a real-life example of why obtaining permits and hiring licensed contractors is critical for safety, compliance, and avoiding costly mistakes.
