Before building a deck or porch whose floor sits more than 30 inches above the adjacent grade, and before a covered porch that would come within 3 feet of a property line.

Quick answer
Eugene exempts low decks and porches from a building permit: no permit is needed where the deck floor is not more than 30 inches above adjacent grade, measured at any point within 3 feet horizontally of the deck. Anything higher needs a residential building permit. A covered porch has an extra condition, that the covered portion stay at least 3 feet from the property line, and the exemption is lost if the deck sits over a septic system or public pipe or encroaches into a public utility easement, floodplain or setback.
Typical threshold: height of the deck or porch floor above adjacent grade, measured at any point within 3 feet horizontally of the floor, with a covered porch also needing to stay at least 3 feet from property lines.

How to apply in Eugene
In Eugene, a residential deck permit application is a set of construction documents that show what will be built and prove it meets the IRC deck provisions. In practice that means a scaled site plan locating the deck and its setbacks, plus deck plans and structural details covering the footings, posts, beams, joists, ledger, guards, and stairs.
What most deck permit applications include:
- For Eugene, a permit application identifying the work, the deck's size (square footage), and whether electrical work such as lights or receptacles is included, submitted for plan review before construction begins (IRC R106).
- For Eugene, a scaled site plan (for example 1/4 inch to 1 foot) showing the new deck's location relative to the house, its overall length and width, and dimensioned distances from the deck to all property lines and other structures so required setbacks can be verified (IRC R106.1.1).
- For Eugene, a deck plan drawn to scale showing overall dimensions and the framing layout: joist size, spacing, span, and species; beam size and span; post size and height; and footing or pier size and depth (IRC R507.4 posts, R507.5 beams, R507.6 joists, R507.3 footings).
- For Eugene, a section or side elevation with connection details showing the ledger attachment to the house band joist with flashing, the fastener or bolt schedule, joist hangers, post-to-beam and post-to-footing connections, and the required lateral load connection (IRC R507.9 ledger connection, R507.9.2 lateral connection, R507.2.4 flashing).
- Footing sizing derived from tributary area, the soil bearing value, and design loads per IRC Table R507.3.1, with footings shown bearing on undisturbed soil at the frost depth required by the jurisdiction (IRC R507.3).
- Details for the guards required where the walking surface is more than 30 inches above grade, and for the stairs and handrails, showing guard height and opening limits, stair riser and tread dimensions, and handrail location (IRC R312 guards, R311.7 stairs and handrails).
- For designs that fall outside the prescriptive R507 tables (for example multi-story or stacked decks, or a ledger attached to a cantilever), engineered and stamped structural plans are submitted in place of the prescriptive details (IRC R507.1 and R301).

Inspections and closing out your permit
In Eugene, deck work is inspected in sequence as it is built: the footings before concrete is placed, the framing before the decking boards go down, and a final inspection once the deck is complete. Each stage checks the items that would be hidden or unsafe if missed.
- Footing or pier inspection in Eugene: after the holes are dug and any forms or reinforcing are set but before concrete is placed, the inspector checks footing depth and diameter, a flat undisturbed bearing surface, and that the holes are free of water (IRC R109.1.1 foundation inspection; R507.3 footings).
- Framing inspection in Eugene: after the deck is framed but before the decking conceals it, the inspector verifies the ledger attachment and its flashing, the fastener and bolt schedule, joist hangers and metal connectors, post-to-beam and post-to-footing connections, and the lateral load connection; call it before decking is installed (IRC R109.1.4 frame inspection; R507.9 ledger and flashing).
- Final inspection in Eugene: after the deck is complete and before it is used, the inspector confirms guard height and opening limits (a 4 inch sphere must not pass, 4 3/8 inch at stairs), stair riser and tread dimensions, handrail height and graspability where there are 4 or more risers, stair landings, and required stair lighting (IRC R109.1.6 final inspection; R312 guards, R311.7 stairs and handrails).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Eugene permit portal or by phone at 541-682-5086.

See the official fee schedule for current amounts.
- How long does a deck permit take in Eugene?
- Decks are one of the project types Eugene lists as eligible for its Residential Express Permit program, where applications are reviewed at 9 a.m., 10 a.m., 11 a.m. or noon on Tuesdays and Thursdays and the city says "our goal is to be able to issue the permit on the same day". That is a stated goal, not a guarantee, and it requires the owner or their authorized agent to be reachable by phone for the whole review slot. Times can vary by workload and project scope, so confirm with the office.
- Where do you apply for a deck permit in Eugene?
- You can apply through the Eugene permit portal or contact the City of Eugene Building and Permit Services, Planning and Development Department directly. The links are listed on this page.
- Can a homeowner pull a deck permit themselves in Eugene?
- Under Oregon law (ORS 701.010(7); ORS 701.325(1), (2), (3)): A homeowner may pull the permit and do the work. ORS 701.010(7) exempts from Construction Contractors Board licensing a person performing work on property that person owns, or on that person's own residence whether or not they own it, so no CCB license is needed to act as your own builder. That exemption does not cover someone working in the pursuit of an independent business with intent to offer the structure for sale. Oregon does require a signed disclosure at the counter: ORS 701.325(1) makes every city, county, or state permit office collect a written statement signed by the applicant, and an applicant claiming a licensing exemption must state the basis for it. ORS 701.325(2) requires the office to give the applicant the Information Notice to Property Owners About Construction Responsibilities and withhold the residential building permit until the applicant signs a statement, one option of which is that they are performing work on property they own or a residence they live in or will live in, and that any contractors they hire will be CCB licensed and properly endorsed. The Information Notice itself is a CCB rule form under ORS 701.325(3) covering payroll tax, workers' compensation, and liability and property damage insurance responsibilities. Confirm how Eugene applies this before you apply.
