Residential Permit Exemptions Examples

Being exempt from a permit does not mean that you can do work that would violate any law or ordinance. Even if it does not require a permit, it should be built to code.

Examples of permit exemptions

  1. Non-habitable one-story, detached accessory structures used as tool and storage sheds, playhouses and similar uses, provided the floor area does not exceed 200 square feet AND a height of 10 feet measured from the finished floor level, to the average height of the roof surface.
  2. Fences not over 6 feet high, except for barriers around swimming pools as required in Appendix G (ORSC).
  3. Retaining walls not over 4 feet in height measured from the bottom of the footing to the top of the wall, unless supporting a surcharge (like a driveway).
  4. Water tanks supported directly upon grade if the capacity does not exceed 5,000 gallons and the ratio of height to diameter or width does not exceed 2 to 1.
  5. Concrete sidewalks, slabs, platforms and driveways.
  6. Painting, papering, tiling, carpeting, cabinets, counter tops, interior wall, floor or ceiling covering and similar finish work.
  7. Prefabricated swimming pools accessory to a Group R-3 occupancy where the pool walls are entirely above the adjacent grade. Barrier requirements found in Appendix G (of the ORSC) are not exempt.
  8. Swings and other playground equipment (including tree houses).
  9. Patio and porch covers not over 200 square feet AND supported by an exterior building wall.
  10. Window awnings supported by an exterior wall which do not project more than 54 inches from the exterior wall and do not require additional support.
  11. Nonbearing partitions, except when such partitions create habitable space.

  13. Retrofitted insulation into existing homes.
