REDMOND, WA — In a city that blends urban development with the natural charm of the Pacific Northwest, Redmond homeowners are increasingly investing in outdoor living spaces. But before breaking ground on that dream custom deck, it’s essential to understand the local rules—and how permits can make or break your timeline.
At King County Decks, we’ve worked with building departments across Redmond, Kirkland, Seattle, and Bellevue, helping homeowners navigate codes, setbacks, and inspections with ease. Whether you’re planning a simple BBQ patio or a multi-level deck with stairs, pergolas, railing, and a jacuzzi, here’s what you need to know before starting construction in Redmond.
When Is a Permit Required in Redmond?
In most cases, yes—you need a permit to build a new deck in Redmond. According to the city’s current regulations:
- Any deck over 30 inches above grade requires a permit.
- Structural changes to an existing deck, such as adding new stairs, enlarging the footprint, or replacing key supports, also require approval.
- Permits are not typically required for ground-level platforms under 200 sq. ft., but it’s always wise to verify.
Decks must also meet the International Residential Code (IRC) standards, as adopted by the State of Washington.
What Else Affects Approval?
1. Setback & Zoning Compliance
Redmond enforces zoning rules that govern how close your deck can be to your property lines, fences, or neighboring structures. This is especially important for corner lots or homes with steep grades.
2. HOA Restrictions
If you live in a Redmond neighborhood with a Homeowners Association, you may need separate approval before obtaining a city permit. Many HOAs restrict railing design, pergola structures, or visible height increases.
3. Soil & Drainage
Decks built on slopes or near wetlands (common in Redmond and Bellevue) may require special engineering to handle drainage and support. At King County Decks, we provide code-compliant designs that address these site-specific challenges.
4. Electrical & Plumbing for Add-Ons
Planning to install lighting, a hot tub, or an outdoor kitchen? You’ll need additional permits for electrical and plumbing—especially for multi-level custom decks with integrated features.
The Inspection Process
Once your permit is issued, you’ll likely go through at least two inspections:
- Framing Inspection — conducted after the structural frame is built, but before decking or railings are installed.
- Final Inspection — ensures the completed structure meets safety, height, and material code.
Decks over 8 feet tall may also require engineered drawings, which our team handles in-house.
What If You Skip Permits?
Cutting corners on permits can lead to:
- Stop work orders
- Fines and fees
- Forced demolition of non-compliant work
- Complications during home sales or insurance claims
Working with a licensed contractor like King County Decks ensures that every phase—from design to final inspection—is fully compliant.
