Tacoma Deck, Fence, and Shed Permit Guide

Tacoma publishes clear permit thresholds for decks, porches, fences, masonry walls, and small storage sheds.

Permit takeaway

Tacoma says most porches and decks require building permits, but a deck may be exempt if it is 200 square feet or less, 30 inches or less above grade, not attached to the house, does not serve a required exit, and is for a single-family house, duplex, or townhouse.

Zoning and placement

Decks must still comply with land-use setback requirements, and fences in critical areas or buffers may need a critical areas permit.

Building and trade review

Fences up to seven feet may be built without a permit if structurally sound, on private property, and not blocking traffic visibility; fences over seven feet and masonry walls over four feet require permits.

Call before applying when

Call before applying if the deck is attached, over 200 square feet, over 30 inches high, serves an exit, the fence is over seven feet, the wall is masonry over four feet, or the site is in a critical area.
