How Long Does It Take to Get a Deck Permit?

Quick Answer

Getting a deck permit takes 2–8 weeks from the time you submit your application to receiving approval. Most straightforward residential deck permits are issued in 2–4 weeks. More complex projects involving variances, HOA review, or environmental setbacks can take 6–8 weeks or longer.

Timeline by Phase

Phase	Typical Time
Prepare plans and application	1–2 weeks
Submit to building department	1 day
Plan review	1–4 weeks
Revisions (if required)	1–2 weeks
Permit issuance	1–3 days
Total	2–8 weeks

What You Need to Apply

Most municipal building departments require the following for a residential deck permit:

• Site plan showing the deck's location on the property, setbacks from property lines, and relationship to the house
• Construction drawings with dimensions, footing details, ledger board attachment, railing height, and structural members
• Material specifications for lumber, hardware, and fasteners
• Proof of property ownership or contractor authorization
• Application fee (typically $75–$500 depending on jurisdiction and deck size)

Preparing these materials takes 1–2 weeks. If you hire a contractor, they often handle the permit application and plan preparation as part of their scope.

Plan Review Process

Once submitted, your application enters the plan review queue. The building department checks your plans against the International Residential Code (IRC) and any local amendments. Key items reviewed include:

• Footing depth and diameter (must reach below frost line)
• Joist span and spacing
• Ledger board attachment method (lag bolts or through-bolts)
• Guard rail height (36 inches for residential, 42 inches if more than 30 inches above grade)
• Baluster spacing (max 4 inches)
• Stair rise and run dimensions

Jurisdiction Type	Typical Review Time
Small town/rural county	3–7 business days
Suburban municipality	1–3 weeks
Large city	2–4 weeks
Areas with HOA review	3–6 weeks (HOA + municipal)

Common Reasons for Delays

• Incomplete applications: Missing drawings or specifications result in a rejection letter and resubmission, adding 1–2 weeks.
• Setback violations: If the proposed deck encroaches on required setbacks, you may need a variance from the zoning board, which can add 4–8 weeks for a hearing.
• HOA approval: Many homeowners associations require architectural review before or in parallel with the municipal permit, adding 2–4 weeks.
• Environmental restrictions: Properties near wetlands, waterways, or flood zones may require additional environmental review, adding 4–12 weeks.
• Backlog during peak season: Building departments in seasonal climates often have longer review times in spring and early summer when deck construction demand peaks.

Expediting Your Permit

Several strategies can speed up the permitting process:

• Submit complete, code-compliant plans on the first attempt to avoid revision cycles
• Use pre-engineered deck plans from lumber suppliers, which departments review more quickly
• Ask about over-the-counter permits for small, simple decks (some jurisdictions offer same-day approval for decks under a certain size)
• Check if your jurisdiction offers expedited review for an additional fee
• Apply during the off-season (fall or winter) when review queues are shorter

Do You Need a Permit?

Most jurisdictions require a permit for any deck attached to the house or elevated more than 30 inches above grade. Some areas exempt small, ground-level decks (under 200 square feet and less than 30 inches high) from permitting requirements, but you should always check with your local building department before starting construction.
