What deck services do we offer in Renton?
The table shows each service and whether Renton usually requires a permit for it.
| Service | What it covers | Renton permit usually needed? |
|---|---|---|
| New raised deck | Footings, frame, decking, railings, and stairs | Yes, when the deck is more than 30 inches above the ground |
| Low, ground-level deck | A platform close to the ground | Often no, if it’s 30 inches or lower, measured within 5 feet around it, and not in a critical area |
| Deck replacement | Old deck removed; new frame and decking built | Usually yes for raised decks |
| Deck resurfacing | New boards, railings, and stairs on a sound frame | Ask Permit Services; depends on what’s replaced |

Permit notes are based on the City of Renton’s Building Permits FAQ. Your project decides the final answer.
Do you need a permit to build a deck in Renton?
Yes, if the deck is more than 30 inches above the ground. Renton measures that height using the ground within 5 feet around the deck, so on a sloped yard a deck that looks low can still cross the line. Any deck work in a critical area, such as near a stream or on a steep slope, needs a permit at any height.
Deck permits in Renton go through plan review; the city’s same-day online permits cover trades like electrical and plumbing, not decks. Renton doesn’t offer paid expedited review. If you hire a contractor, the contractor needs a Washington State contractor license and a City of Renton business license before the city issues the permit.
| Renton rule | What it means for your deck |
|---|---|
| More than 30 inches above the ground | Permit required |
| Height measured within 5 feet around the deck | Sloped yards can push a low deck over 30 inches |
| Critical areas (streams, wetlands, steep slopes) | Permit required at any height |
| Contractor licensing | WA contractor license and Renton business license before the permit is issued |
| Work before the permit | Not allowed; clearing under 500 sq ft can start early outside critical areas |

What’s different about building a deck in Renton?
| Renton factor | Why it matters | How we plan for it |
|---|---|---|
| Hillside lots | Many Renton yards slope, which affects the permit height and the footings | We measure height at several points, including the 5-foot band around the deck |
| City or county? | Some Renton mailing addresses are outside city limits and follow King County rules | We check your address on Renton’s COR Maps before planning permits |
| Northwest rain | Water, not wear, is what ruins decks here | Ground-contact lumber near soil, a flashed house connection, and drainage gaps |
| Washington deck load | Washington designs decks for a 60 psf load, higher than many states | Every frame is sized to Washington’s requirement |
| Work hours | Renton allows remodel work 7 a.m.–10 p.m. weekdays, 9 a.m.–10 p.m. weekends | Scheduling respects your neighbors and the city’s hours |
Refinish, resurface, or replace your Renton deck?
| Option | What we do | Choose it when |
|---|---|---|
| Refinish | Clean, sand, repair a few boards, apply new stain | The deck feels solid and just looks worn or gray |
| Resurface | Keep the frame; replace boards, railings, and stairs | The frame is solid but many boards are cracked or soft |
| Replace | Remove the whole deck and build new | The frame, posts, or house connection are rotting |

Patios in Renton
A patio adds ground-level space for a fire pit, dining, or a hot tub, and pairs well with a deck off the house. We build concrete and paver patios in Renton and plan the levels and drainage together with the deck, so water slopes away from your house instead of pooling. See our paver patio services.

What our deck and patio 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!
Amazing service and professional work! Dawn Construction built our new patio, and we couldn't be happier. The team worked efficiently, finished on time, and paid close attention to every little detail. The patio looks fantastic and completely upgraded our backyard. I highly recommend them to anyone looking for a dependable contractor who delivers great results
Decks in Renton: frequently asked questions
Do I need a permit to build a deck in Renton?
Yes, if the deck is more than 30 inches above the ground. Renton measures that height using the ground within 5 feet around the deck, so a deck on a sloped yard can cross the line even if it looks low. Any deck work in a critical area, such as near a stream or on a steep slope, needs a permit at any height.
Who can apply for a deck permit in Renton?
A homeowner can apply to build on their own property. A contractor must have a Washington State contractor license and a City of Renton business license before Renton will issue the permit.
Is my home in Renton or unincorporated King County?
Some homes with a Renton mailing address are outside city limits and follow King County’s permit rules instead. You can check your address on the City of Renton’s COR Maps tool, and we check it during the estimate.
What hours can a deck crew work in Renton?
For single-family remodel work, Renton allows construction from 7 a.m. to 10 p.m. on weekdays and 9 a.m. to 10 p.m. on weekends.
Should I refinish my old deck or replace it?
Refinish it if the frame underneath is solid and only the surface looks worn. Replace it if boards or framing are soft, the railing wobbles, or the spot where the deck meets the house is rotting.
What is the best decking for Renton’s rain?
Capped composite needs the least upkeep, only cleaning. Cedar gives a natural wood look but needs a fresh finish every few years. Pressure-treated wood costs least up front but needs regular cleaning and sealing.
How much does a new deck cost in Renton?
It depends on the size, height, decking material, railings, and stairs. You get a written quote after a free in-home estimate, and financing is available.
Do you build patios in Renton too?
Yes. We build concrete and paver patios in Renton, on their own or together with a new deck, and plan the levels and drainage so the space works as one.
