Meridian, ID Deck Permit Rules (2026)

When does a Meridian deck need a permit?

Meridian's rule is about size and connection, not a height line. The city's Residential Detached Accessory Structures handout counts decks as accessory structures and lists the triggers. Answer these four questions; one yes means you need a permit from Building Services:

1. Is the deck bigger than 200 square feet?
2. Is it attached to the house, even by a single ledger board?
3. Is it more than one story?
4. Does it serve the exit door the code requires for the home?

Most decks that homeowners actually want fail the second question. A deck off the back slider is almost always ledgered to the house, and that alone makes it permit work in Meridian no matter how low or small it is.

Reading the exemption closely

The exemption at the bottom of the handout mirrors the 2018 IRC's model language, and every condition has to be true at once:

• 200 square feet or less in area.
• Not more than 30 inches above grade at any point. On a sloped yard, that is the highest point, not the average.
• Not attached to a dwelling.
• Not serving the exit door required by IRC Section R311.4. If the deck is the landing outside the home's required egress door, it is not exempt.

Compare that with Boise's 12-inch rule: a detached 180 sq ft deck at 24 inches is exempt in Meridian and needs a permit a few miles east. Neighbors comparing notes across the city line are often both right.

Where can an exempt deck go?

An exemption from the building permit is not an exemption from zoning. Meridian's handout sets placement rules for accessory structures: none in the street yard or the required side yard, and on corner lots nothing between the house and the street. One detached accessory structure of 200 sq ft or less may sit in the required rear yard without a building permit, but the handout warns that rear-yard structures are likely sitting on an easement.

Typical recorded easements are 10 feet at the rear and 5 feet at interior sides, 15 feet on a corner lot's street side. If a utility needs that easement, the owner moves and replaces the structure at their own expense. Those rules are written around sheds, so call Meridian Planning at 208-884-5533 to confirm how they apply to a low freestanding deck before you set the first pier.

Do covers and pergolas need a Meridian permit?

Meridian treats patio covers, arbors, pergolas and gazebos the same way it treats small decks. Detached and under 200 square feet: no building permit. Over 200 square feet: a Residential Patio Cover permit (R-PATIO), and the structure has to meet rear and side setbacks. Anything attached to the house is an addition under the IRC. A covered deck built off the house is permit work twice over, once for the deck's attachment and once for the roof.

What do you submit, and what do inspectors check?

Meridian's handout explains when a permit is required but doesn't list deck drawings, so confirm the current checklist with Building Services at 208-887-2211 before you draw. Expect the core set any 2018 IRC jurisdiction reviews: a site plan with setbacks and easements, a framing plan, a section from footing to guard, and the ledger connection detail.

Footings follow the same 24-inch frost line Meridian's shed handout uses for heated and larger structures; our footing depth guide covers sizing. Inspections are requested through the city's inspection line, 208-887-1155. Third-party guides describe the typical deck sequence as footing, framing and final; your permit card is the authority on what Meridian actually calls for.

Meridian HOAs: the second approval

Meridian's handout tells homeowners to verify HOA requirements, and in many of the city's subdivisions that is a real step. Architectural committees commonly weigh in on materials, colors, deck height and placement. Third-party permit services estimate HOA review at one to six weeks; plan for the slow end and read our HOA approval guide for what to submit. For ground-level decks in Meridian's subdivisions, composite decking is the common request, and HOA color lists often decide the board.

Quick checklist before you call Meridian

• Measure the deck's highest point above grade and its total area.
• Note whether any part touches or is fastened to the house.
• Find your lot's recorded easements on the subdivision plat.
• Pull your CC&Rs and the HOA's application form.
• If a cover or pergola is in the plan, size it now so the permit covers it.
