How to Get a Deck Permit in 2026

Getting a deck permit isn't complicated, but the process varies by city. After researching 100 US cities, here's a step-by-step guide based on how permitting actually works across the country.

Step 1: Determine If You Need a Permit

Before anything else, check whether your deck actually requires a permit. In most cities, you need one if your deck meets any of these criteria:

More than 30 inches above grade

Attached to the house

Larger than 200 square feet

Serves a required exit door

Some cities require permits for ALL decks regardless — see our guide to cities with no exemptions.

How to check: Find your city in our deck permit guides or call your local building department.

Step 2: Gather Your Documents

Every city requires some combination of these:

Required everywhere:

Site plan: Shows your property boundaries, house location, and where the deck goes

Deck dimensions: Length, width, height above grade

Construction details: Joist sizes, beam spans, post spacing, footing depth

Sometimes required:

Property survey: Buffalo, NY requires one for all deck permits

Engineered drawings: Required for complex designs or when deck exceeds 30 inches in Irvine, CA

HOA approval letter: Irvine, CA requires this for condominiums

Historic district approval: Required in historic areas of Philadelphia, Boston, Charleston, Savannah, and many others

Pro tip: Use prescriptive deck guides

Several cities provide ready-made deck plans that comply with code:

Madison, WI accepts the DCA6 Prescriptive Residential Deck Construction Guide

Spokane, WA provides a Prescriptive Deck Construction Guide

Knoxville, TN offers a Prescriptive Residential Wood Deck Construction Guide

Using these pre-approved plans can dramatically speed up your approval.

Step 3: Submit Your Application

Nearly every major city now accepts online applications:

Standard decks: $100-$300

Large/complex decks: $300-$500+

Expedited review options

Some cities offer faster processing:

Kansas City, MO offers priority status at 2x the permit fee

Chandler, AZ offers walk-in same-day review for simple projects

Step 6: Build and Schedule Inspections

Once approved:

1. Post your permit visibly at the job site (some cities like Chesapeake, VA require it to be visible from the road)

2. Schedule inspections at required stages:

- Footing inspection: Before pouring concrete — inspector verifies depth reaches frost line - Framing inspection: After structure is up but before decking is installed - Final inspection: Completed deck with railings, stairs, and all finishes

3. Don't cover previous work before it's inspected. If you pour concrete before the footing inspection, you may need to dig it up.

Step 7: Get Your Certificate of Completion

After passing final inspection, you receive documentation that the work was permitted and inspected. Keep this document — you'll need it when you sell your home.

Special Situations

Philadelphia's EZ Deck Permit

Philadelphia offers a streamlined "EZ Deck Permit" for small decks (≤160 sq ft, rear yard, single-family). No architectural plans needed, same-day approval in person.

Owner/Builder in Florida

In Florida cities like Orlando, homeowners can pull permits as Owner/Builder with a signed declaration and video verification. No contractor license needed for your own home.

New Jersey Licensed Professional Requirement

In NJ cities like Jersey City and Newark, plans must be prepared by a NJ licensed architect or engineer. This is a state-level requirement through the Uniform Construction Code.
