Deck Permit
Deck Permits, Footings, and Inspections
Decks are one of the highest-risk DIY permit projects because footing depth, ledger attachment, guardrails, and stairs are safety-critical.
Permit likelihood
Almost always required for attached decks, elevated decks, structural repairs, and decks with stairs or guards.
Typical permit cost
$75-$500 for typical residential review; engineered plans can raise project costs.
Planning timeline
One to six weeks depending on plan review, frost-depth requirements, and engineering.
Common permit triggers
- Deck attached to the house
- Walking surface above grade
- New stairs or guardrails
- Ledger replacement or structural repair
Documents to gather before applying
- Deck plan with dimensions
- Footing size and depth
- Ledger attachment detail
- Guardrail, stair, and handrail details
Inspection sequence to plan around
- Footing holes before concrete
- Framing and ledger inspection
- Guardrail/stair inspection
- Final inspection
Mistakes that create delays
- Using nails where bolts or structural screws are required
- Shallow footings in frost zones
- Weak ledger flashing
- Guard openings that fail code
State and city variation
Frost depth, snow load, seismic rules, and local amendments can change footing and connection requirements.
Contractor questions
- Who is responsible for pulling the permit?
- Will the permit list the full scope of work?
- Which inspections must happen before work is covered?
- Are permit fees, corrections, and reinspection fees included in the quote?
- Will I receive copies of approvals and final inspection records?
