  • Property lines, with dimensions
  • Adjacent streets and any easements
  • Property address and R number
  • North arrow
  • Distance between buildings and between buildings and property lines
  • Dimensions and placement of the new fence on the lot

Structural Plans (Scale of plans to be ¼”=1’)

  • Foundation plan showing location and size of footings and posts
  • Elevation view showing fence framing including dimensions, lumber size, spacing, footing size/depth and span
  • Connections to existing construction

To submit for a permit, bring the completed building permit application and four (4) copies of site, architectural and structural plans (for the area of proposed work and areas affected by such work ) along with intake fees to the Development Services Center.

Important Things to Consider When Planning Your Project:

(1) Setbacks

Fences may be built on private property, so long as they meet certain height and setback requirements. A setback is the distance measured from your property line to a point inside the property. A setback creates a border inside your property lines. Setback requirements are different in each residential zone. A front setback is usually larger than the side and rear setbacks. For purposes of determining setback, the front is the side that borders a street. On a corner lot, the front is the shortest side of the lot that borders a street. If the street frontages are of equal length, you may choose which to call the front.

Visit the Planning and Zoning staff at the Development Services Center or call (503) 823-7526 for help with:

  • Identifying the zone where the property is located
  • Determining the setback requirements for the project
  • Identifying any requirements if the property is located in a design, greenway or overlay zone

Fences taller than eight feet must meet the requirements listed below:

Zone RF R20 R10 R7 R5 R2.5
Front Setback 20 feet 20 feet 20 feet 15 feet 10 feet 10 feet
Side/Rear Setback 10 feet 10 feet 10 feet 5 feet 5 feet 5 feet

(2) Front Yard Fences
If you are planning to build a fence in your front yard, call the Portland Bureau of Transportation/Engineering at (503) 823-7002 for help in locating property lines along a street. Property lines that divide your lot from your neighbors may be harder to find.

(3) Structural Engineering
Fences taller than six feet measured from the owner's side at grade level must be built to resist winds.

(4) Pressure Treated Materials
Any part of a wood fence that touches concrete or that is within six inches of the ground must be pressure-treated wood or wood that is naturally resistant to decay, such as cedar or redwood. Pressure treated wood installed below grade must be stamped as approved for ground contact.
