How to Apply for a Deck Permit
Ten steps from confirming you need a permit to closing it out after final inspection.
Quick Answer: Draw a site plan and construction plans, estimate your project value, submit to your building department (usually online), pay the fee, wait 1 to 3 weeks for plan review, then schedule footing, framing, and final inspections as you build.
The 10 Steps
Total: 2 to 6 weeksConfirm a permit is required
Call your building department or use our "Do I need a permit?" quiz. Note the deck size, height above grade, attachment method, and any utilities. If the department tells you no permit is needed, write down the date and staff name as your record.
Take the quizDraw a site plan
Show your property lines, existing house, proposed deck location, all dimensions, and setback distances to property lines. Most cities accept hand drawings on graph paper if they are neat and to scale. Include a north arrow and scale (typically 1 inch = 10 feet).
Draw construction plans
You need three views at minimum. Plan (top-down) showing joist layout, beam locations, post positions. Elevation (side) showing overall height, railing detail, stair configuration. Cross-section showing ledger attachment, joist-to-beam, post-to-footing connections. For prescriptive-code decks (following IRC R507 tables), one-page drawings are often accepted.
Estimate project valuation
Most cities ask for your estimated construction cost on the application. Rule of thumb: $25 to $50 per square foot for pressure-treated lumber, $40 to $80 for composite decking. Be accurate — cities audit valuations against market rates, and inflated or deflated numbers both raise flags.
Gather supporting documents
Typical packet: completed application form, site plan, construction plans, proof of property ownership (deed or tax record), contractor license and insurance (if using one), any HOA approval letter required by your covenants. Some cities also require a soil bearing statement or grading plan.
Submit your application
Most cities offer three submission channels: online portal (upload PDFs, pay with card), in-person counter (bring printed copies), or email submission. The online portal is usually fastest and gives you a tracking number. Expect a plan review deposit of 25% to 40% of the total fee at submission.
Wait for plan review
Plan review timelines vary. Simple residential deck: 5 to 15 business days. Complex structures: 2 to 4 weeks. The reviewer will either approve, approve with conditions, or send a correction list. If corrections are requested, fix them and resubmit (usually free the first time).
Pay the balance and pick up the permit
Once approved, pay any remaining permit fee (flat fee or valuation-based balance). You will receive an approved permit card — post it visibly at the job site. Some cities email a PDF, others require you to pick up a paper card.
Schedule inspections as you build
Call or use the online portal to schedule each inspection. Typical sequence: footing inspection (before concrete pour), framing inspection (before decking goes down), final inspection (after everything is complete). Do not cover work that has not been inspected.
Pass the final inspection and close the permit
After the final passes, the city issues a Certificate of Completion (or closes the permit in their system). Keep this document with your house records — title companies ask for it on sale. An open permit on a property can block a real-estate closing.
What Goes on the Construction Plans
Plan reviewers look for the same items on every deck. Include these and you avoid 80% of correction requests.
Overall dimensions
Length and width of the deck, total square footage, and height above grade at each corner.
Joist layout
Joist size, species, spacing (typically 12" or 16" on center), direction, and span from beam to ledger.
Beam specification
Number of plies, lumber size, species, total span between posts, and any splice locations.
Post sizing and locations
4x4 or 6x6, height of each post, and spacing between posts along each beam.
Footing detail
Diameter, depth (must be below frost line), concrete spec, and post-to-footing connector model.
Ledger detail
Lag bolt or through-bolt size and spacing, flashing detail, and whether attached to rim joist or engineered lumber.
Railing detail
Post size and attachment, top rail height, baluster size and spacing, and how the 4-inch sphere rule is met.
Stair detail
Total rise, total run, number of risers and treads, stringer size, handrail attachment.
Top 5 Reasons Plans Get Rejected
Missing ledger board attachment detail
Fix: Include fastener type, size, and spacing. Reference IRC Table R507.6 if using prescriptive code. Show flashing.
Footing depth not specified
Fix: State the frost line depth for your jurisdiction and show the footing extends below it. A generic "below frost line" note is often rejected.
Joist span exceeds code tables
Fix: Check IRC R507.5 tables for your lumber species and size. If the span is too long, increase joist size or add a beam.
Site plan missing setbacks
Fix: Show the distance from each deck edge to the nearest property line. Most cities require 3- to 10-foot setbacks.
Railing height not shown or wrong
Fix: Note the railing height explicitly (36" or 42" depending on jurisdiction) and call out the 4-inch baluster rule.
Inspection Schedule
Most residential deck permits require three inspections. Schedule each one before you cover the work it inspects.
Footing inspection
When: Before pouring concrete
What they check: Inspector verifies hole depth (below frost line), diameter, and rebar placement. Usually a 5-minute visit.
Framing inspection
When: After posts, beams, joists, and ledger are in place, but before deck boards or railing are installed
What they check: Inspector checks structural members, ledger attachment, flashing, fasteners, and connector hardware. This is the most detailed inspection.
Final inspection
When: After deck boards, railing, stairs, and any electrical work are complete
What they check: Inspector verifies railing height, baluster spacing, stair dimensions, handrail graspability, and overall compliance. Passing this closes the permit.
Frequently Asked Questions
How long does a deck permit take to get approved?
Simple residential deck permits typically approve in 1 to 3 weeks. Complex designs, second-story decks, or projects in busy jurisdictions can take 4 to 8 weeks. Many cities offer expedited review for an additional fee (typically $100 to $300).
Can I apply for a deck permit online?
Most cities with populations over 50,000 now accept online permit applications through a dedicated portal. Smaller jurisdictions may still require in-person submission at the building department counter. Our city guides list the portal URL and submission method for each.
Do I need an architect or engineer to apply?
Usually no. Simple residential decks following prescriptive code (IRC R507) can be submitted with homeowner-drawn plans. Second-story decks, cantilevered designs, or decks supporting hot tubs or heavy loads typically require a licensed engineer or architect ($500 to $2,000 for deck plans).
What if my plans are rejected?
You will receive a list of deficiencies. Correct the issues and resubmit. Most cities allow one or two free resubmissions before charging a re-review fee. Reasons for rejection: missing details on drawings, undersized structural members, missing ledger details, inadequate footing specifications.
Can I start work before the permit is approved?
No. Starting work before permit issuance is itself a code violation even if you eventually would have qualified. Cities can issue stop-work orders and double the permit fee as a penalty. Wait for the approved permit in hand before breaking ground.
Do I need to be the homeowner to apply?
No. Licensed contractors routinely pull permits on behalf of homeowners. Some cities allow authorized agents (contractors, architects) to apply with a signed owner-authorization form. The permit stays in the homeowner's name for liability purposes in most jurisdictions.
How many inspections will I need?
Most deck permits require 2 to 3 inspections: (1) footing or foundation before pouring concrete, (2) framing after the structure is up but before decking is installed, and (3) final inspection after the project is complete. Schedule each inspection before the work it covers is hidden.
