Do you need a permit to replace a deck in Mukilteo?
Usually. Mukilteo doesn’t require a permit for a deck that’s less than 200 square feet and less than 30 inches from the ground. If you’re building or replacing a deck that’s larger or higher than that, you need a building permit.
| Your new deck | Permit? |
|---|---|
| Less than 200 sq ft and less than 30 inches from the ground | No building permit |
| 200 sq ft or larger | Building permit |
| 30 inches or higher from the ground | Building permit |
| Any deck near a steep slope or other sensitive area | May need environmental or land use review, even if exempt from a building permit |
Mukilteo’s Building Division reviews plans and performs inspections. For questions, the city lists [email protected]. We check your project with the city and handle the permit and inspections.
What’s different about replacing a deck in Mukilteo?
| Mukilteo factor | Why it matters | How we plan for it |
|---|---|---|
| Hillside lots | Many decks sit high on one side, which affects the permit and the footings | We measure height at several points and size posts and footings for the slope |
| Sensitive areas | Work near steep slopes can need extra review | We check with the city before design |
| Water views | Railings can block the view you built the deck for | We help you choose railings that keep the view open |
| Northwest rain | Water, not wear, ruins most decks here | Ground-contact lumber near soil, a flashed house connection, and drainage gaps |

What our deck customers say
Did a great job of deck refinishing. Not the cheapest, but very good quality. The deck had tons of small areas and crevices and Vitali did a great job getting into every area for a double stain coating!
Deck replacement in Mukilteo: frequently asked questions
Do I need a permit to replace a deck in Mukilteo?
Usually. Mukilteo doesn’t require a permit for a deck that’s less than 200 square feet and less than 30 inches from the ground. If you’re building or replacing a deck that’s larger or higher than that, you need a building permit.
Does a deck under 30 inches ever need extra review in Mukilteo?
It can. Work that’s exempt from a building permit is still subject to safety standards and may need environmental or land use review, which matters on Mukilteo’s hillside lots.
Should I replace my deck or just the boards?
If the frame, posts, footings, and house connection are solid, new boards and railings can be enough. If the frame is rotting in many places, replacing the whole deck is usually the better choice.
What decking can you use for a replacement?
We build replacement decks in composite, cedar, and pressure-treated wood. Composite needs the least upkeep in our rain; cedar gives a natural wood look.
Can you make my new deck bigger or change its shape?
Yes. Replacing a deck is a good time to change its size, shape, stairs, or railings. A larger or higher deck may change what the permit needs.
Can you add a cover when you replace my deck?
Yes. Building the new deck and a cover together lets the posts, beams, and footings be sized for the roof from the start.
What affects the cost of a deck replacement?
Size, height, decking material, railings and stairs, removal of the old deck, repairs at the house connection, the slope of the lot, and the permit. Every deck is priced individually, with a written quote after a free in-home estimate.
Do you offer free estimates and financing?
Yes. Every project starts with a free in-home estimate and a written quote, and financing is available.
