Do I need a permit for a deck in Bend?

Usually, for anything beyond a low, simple platform. The City of Bend's permitting guide says a deck or porch needs a building permit if it is more than 30 inches above the ground or has stairs. A pergola or patio cover needs one if it is over 12 feet tall or over 200 square feet. Electrical work for lighting or outlets, plumbing for an outdoor sink, and a gas line for a grill each need their own permits; standalone solar and plug-in lights do not. Apply through the city's online Permit Center portal with a site plan and detailed deck plans. The city says review typically takes two to three weeks and inspections usually cover footings, framing and a final. It also flags extra requirements in the Waterway Overlay Zone along the Deschutes River and Tumalo Creek, for historic properties, and where a deck could land in a utility easement.

What if I live outside Bend?

Inside Redmond, the City of Redmond's Building Division issues permits, with zoning questions going to its Planning Department. In Sunriver, Tumalo, Deschutes River Woods and other unincorporated areas, Deschutes County's Community Development Department handles building permits. The county's Building Safety Division also took over the City of Sisters' building program in July 2016. Sunriver homes also go through the Sunriver Owners Association's Design Committee.

Is there a free deck plan?

Yes. In April 2025, the Oregon Building Codes Division released a free permit-ready plan for a one-level, wood-framed deck attached to a house. You download it, add your project's dimensions and site design criteria, and submit it to your local building department for review.

Who can build my deck?

The Oregon Construction Contractors Board says it is illegal to build, remodel or repair homes for pay without a CCB license, and that handymen doing work valued at $1,000 or more must be licensed too. Licensed contractors carry insurance and a bond, and those working on homes also need a residential endorsement; without it, a homeowner can't use CCB mediation or the bond. Ask for the CCB number, look it up on the board's license search, confirm the name matches, and read the complaint history, which goes back ten years.

How deep do footings go, and what about snow?

Deschutes County's building design criteria list an 18-inch minimum frost depth. The Oregon prescriptive deck guide sets frost depth by region at 12, 18 or 24 inches and requires footings to bear on undisturbed native soil. The county says snow load is site-specific and has to be determined from the Oregon Snow Load Map, which matters most for deck roofs and pergolas. Confirm both numbers for your address with your building department.

What are the basic guard and stair rules?

The Oregon prescriptive deck guide, based on the 2023 Oregon Residential Specialty Code, calls for guards at least 36 inches tall with openings that won't pass a 4-inch sphere, a handrail on stairs with four or more risers, guards on open stair sides with a total rise of 30 inches or more, 36-inch landings at the top and bottom, and a light at the top landing.

Does Oregon's wildfire code apply to my deck?

Probably not to a new deck on an existing house in Bend. The city adopted section R327 of the Oregon Residential Specialty Code on April 15, 2026, effective May 15, 2026, for new detached homes and new accessory structures, and the city says it does not apply to additions or renovations. For new homes it covers, R327 sets rules for deck walking surfaces between 30 inches and 12 feet above grade: ignition-resistant material, fire-retardant-treated wood, noncombustible material, or products that pass the ASTM E2632 and E2726 fire tests. Decks of 200 square feet or less built with nominal 2-inch lumber are an exception.

How do decks catch fire?

A Firewise USA fact sheet on research by the Insurance Institute for Business and Home Safety found that ember-ignited deck fires started in the gaps between deck boards and grew in the space below. It says nothing that can burn should be stored under a deck, notes that cedar and redwood are vulnerable to embers, and suggests wider board gaps, wider joist spacing and foil-faced flashing tape on top of joists. FireFree, run by Project Wildfire and Deschutes County since 1997, holds free yard debris collection in spring at Knott Landfill in Bend and transfer stations in Redmond, Sisters and La Pine, and it accepts pine needles.

What does the climate do to decks?

Bend has a cold semi-arid climate at about 3,600 feet, with roughly 10.6 inches of precipitation and 21.6 inches of snow a year. Records run from 26 below zero to 107 degrees. Strong sun and dry air dry out wood and wear down finishes, while snow and freeze-thaw cycles work into gaps and fasteners.

Questions to ask a builder

What is your CCB number, and do you have a residential endorsement?
Who pulls the permit, and which inspections will there be?
How deep will the footings go, and how will you handle rock if we hit it?
How will the ledger be attached and flashed, or will the deck be freestanding?
What decking and railing do you suggest for sun, snow and embers on my lot?
What does your warranty cover, and what do the manufacturers' warranties cover?

Common questions

Can I build a low deck in Bend without a permit?

The city's guide says a deck or porch under 30 inches high and without stairs typically doesn't need one, but it also says to check with staff. Wiring, plumbing or gas still need permits.

How do I check a deck builder's license?

Ask for their CCB number and look it up on the Oregon Construction Contractors Board's online license search, which also shows complaint history.

Does Bend's wildfire code apply to my new deck?

The city says R327 applies to new detached homes and new accessory structures, not to additions or renovations of existing buildings. Ask the city if you're unsure how your project is classified.
