A code-compliant deck is more than a solid build. It must meet written standards, pass inspections, and be recorded as approved by your city. Every part, such as the ledger, beams, joists, stairs, and rails, must follow code rules to ensure safety.
Because codes change between cities, permits and inspections matter at every step. We design clear plans, follow span tables, and document the work so inspectors can sign off. Below, we explain how to plan, build, and close out a code-compliant deck.
What Does the Deck Code Cover?
A deck is a system. Each part must meet size, span, and connection rules. Inspectors look at:
- Ledger attachment to the house
- Pier depth and diameter
- Beam size and span
- Joist size and spacing
- Stair rise and run
- Guard and handrail height and strength
Ledger Attachment Rules that Prevent Failures
The ledger carries a lot of the load. We:
- Use approved fasteners and patterns.
- Flash and seal the connection to keep water out.
- Avoid attaching to weak surfaces like brick veneer.
- Follow the exact bolt spacing listed in your code book.
Key Takeaway: The ledger is a top failure point. Proper bolts, flashing, and spacing protect your home and pass inspection.
Footings, Beams, and Joists that Match Spans
Footings must reach the required depth and width. Beams and joists must match span tables.
- Footings: correct depth below frost line, bell shape when required.
- Beams: proper ply count and size for the span.
- Joists: spacing often 12, 16, or 24 inches on center, based on material and span.
Pro Tip: Ask for the span table page used for your design. Keeping a copy helps during inspection and resale.
Safe Stairs, Guards, and Handrails
Stairs must keep a steady rise and run. Guards and handrails must meet height and grasp rules.
- Typical stair rise and tread run must be uniform within small limits.
- Guard height is often 36 inches or more.
- Handrails must be graspable and return to a wall or post.

How to Plan a Code-Compliant Deck in Your City
Start with your local rules. Codes and forms change by municipality. We check the current edition and any local amendments.
- Site visit and measurement.
- Drawings that call out sizes, spans, and connections.
- Permit application with your city or county.
- Scheduled inspections for footings, framing, and final.
- Corrections if the inspector requests them.
- Final sign-off and record of approval.
Bold Tip: Keep your approved plans on site. Inspectors often ask to see the exact sheets during visits.
Permits, Inspections, and Closing Out the Job
A permit gives you permission to build as drawn. It does not prove the deck was built that way. Only passed inspections and a closed permit show that work met code.
- We pull the permit as the contractor of record.
- We call and schedule each inspection.
- We fix any notes right away.
- We close the permit and secure the final approval.
If a permit sits idle, many cities void it after 180 days of no activity. An open or expired permit means nothing in the record. After final approval, most jurisdictions issue a Certificate of Completion or Certificate of Occupancy for decks and porches. This is your proof.
Key Takeaway: Do not stop at “permit issued.” Make sure the permit is closed and the final approval is recorded.
