Guide
Who issues your permit, and what a complete set looks like.
Permit review is not a mystery. It is a checklist. Most of the delay homeowners blame on the county is a package that arrived incomplete.
Who actually reviews your drawings
In the Triangle, residential permits are issued either by the municipality your address sits inside or by the county, if it does not. That one distinction decides which checklist, which portal and which fee schedule applies to you, and it is the first thing to settle, because a package formatted for the wrong office is a wasted cycle.
The counties this guide covers are Wake, Durham, Orange, Chatham and Johnston. Inside those counties, the larger municipalities run their own inspections departments. A house in the city of Raleigh, a house in unincorporated Wake County and a house in Cary are three different reviews even though they are twenty minutes apart.
Zoning is a separate question from building code, and it is answered locally too. Setbacks, impervious surface limits, overlays and historic districts come from the adopted zoning ordinance rather than from the state residential code, which is why the first step on any project is pulling the parcel's zoning classification from the county GIS and reading it against the local unified development ordinance. That is covered in foundation setbacks and frost depth.
What a complete residential submittal contains
Requirements vary by office and the current checklist always wins. Most North Carolina residential packages ask for the same core, and a set missing any one of these is the usual reason a submittal comes back before review even starts.
- The completed application, signed by the owner or an authorized agent
- A plot plan with property lines, the structure footprint, required setbacks, easements and impervious surface calculations
- A foundation plan with footing sizes, reinforcement and anchor bolt layout
- Floor plans for every level, with room labels and overall dimensions
- Elevations for all four sides, with finished floor elevations shown relative to grade
- A wall section showing insulation values, air sealing details and the weather resistive barrier
- A framing plan with member sizes, spans and connector callouts
- A roof plan with slope, sheathing and underlayment specified
- A window and door schedule with U-factors and egress opening sizes
- Mechanical, electrical and plumbing plans or riser diagrams
- Manual J, S and D load calculations with the equipment selection
- Energy code compliance documentation, prescriptive or by trade-off

What triggers a stamped sheet
A stamped structural package from a licensed professional engineer is required once the design leaves the prescriptive framing tables in the adopted code. The common triggers are a cantilever longer than the table allows, a beam span past what the tables cover, and a wall taller than 10 feet.
Site conditions add their own. Expansive soil, a steep slope, high wind exposure or a retaining wall over four feet typically brings a stamped foundation design. A site with a history of fill or known settlement needs a soils report from a licensed geotechnical engineer before the foundation is designed at all, because the default assumed bearing capacity in residential design is 1,500 pounds per square foot and a site that cannot deliver it changes every footing on the plan.
Knowing which sheets need a stamp at the start rather than at review is most of what separates a smooth permit from a slow one.
How packages get rejected
Two categories, and both are avoidable.
Format. Most North Carolina counties now accept or require digital submission, and each portal has its own rules: PDF only, one file per sheet or one combined file, a maximum file size and a naming convention. A submission rejected on format costs a full review cycle even though nothing was wrong with the drawings.
Content. The gaps repeat, package after package:
- Energy code compliance documentation missing or incomplete
- Manual J, S and D not included
- A wall section with no air sealing or weather resistive barrier detail
- A plot plan with no impervious surface calculation where local stormwater rules require one
- A window schedule missing U-factors or egress opening sizes
- The owner's signature missing from the application
Do I need a permit for this?
The reliable answer is scope by scope, and the reviewing office for your address has the final word. What follows is how these scopes usually land in this market.
- An addition. Yes. It changes the footprint or the structure, and it brings a zoning review as well as a building review.
- A kitchen renovation. Usually yes, at minimum for the electrical and plumbing work, and certainly if a wall moves or the layout changes. See kitchen renovation.
- A bathroom renovation. The same rule. Fixture swaps in place are the lightest case, and anything that moves a drain or adds a circuit is not that case.
- A deck or a porch. A roofed structure attached to the house is a structural addition. Decks depend on height and attachment, and the threshold is set locally. Separately, the adopted code requires a guard on any deck or porch more than 30 inches above the floor or grade below, measured within 36 inches horizontally of the edge.
- A detached structure. It depends on size and use, and on whether it takes power or plumbing. A conditioned backyard structure is a building, whatever it is called on the plan.
- Windows and doors in existing openings. Often lighter review, but egress still applies. Every sleeping room needs an emergency escape and rescue opening: 5.7 square feet net clear, or 5.0 on a grade floor opening or a basement opening onto an egress well, with a minimum clear height of 24 inches and width of 20 inches. See egress windows.
How long it takes, honestly
Review time is set by the office and by the season, not by your designer, and anyone quoting you a universal number for the Triangle is guessing. What is inside your control is whether the package that arrives is complete, because an incomplete one adds a full cycle on top of whatever the base time is.
We are building a verified directory of the permit offices we file with: office name, address, phone, hours, portal, fee schedule and typical residential turnaround, each with the date it was confirmed. Every value in it has to come from the county's own source or a phone call to the office, never from another firm's website, which is why it is being filled in slowly rather than quickly. The current state of it is at NC permit offices, and this article will carry the numbers once they are confirmed.
Questions we get asked
- Can I pull my own permit as a homeowner?
- Homeowners can often pull a permit for work on their own residence. The rules, including any limit tied to selling afterward, are set by state law and by the reviewing office. Ask the office for your address before you rely on it.
- Do you submit the permit for me?
- Offices generally require the owner or a licensed contractor to submit, and we confirm the rule for your address before we hand the package over. We prepare the package to the checklist, hand it over ready to file, and answer reviewer comments if any come back. See permit drawings.
- What happens if I build without a permit?
- Unpermitted work surfaces at resale, at appraisal and at insurance claim time, and the fix is usually opening finished work so it can be inspected after the fact. It is the most expensive way to save a permit fee.
- Does a permit require stamped engineering?
- Not always. A design that stays inside the prescriptive framing tables in the adopted code generally does not need one. A design that leaves them does.
- Who decides my setbacks?
- The local zoning ordinance, not the state residential code. Pull the parcel's zoning classification from the county GIS, then read it against the zoning table in the local unified development ordinance. Decks, porches and cantilevers count toward setback measurement even when they do not share the main foundation.
