Every Project Type in Raleigh

These summaries come from the same official sources as our city pages and were last checked October 30, 2026. Permit counts are the city's own open-data records for the last 12 months.

Roofing: Often No

North Carolina law exempts replacing roofing on a house when the project costs $40,000 or less, and the state fire marshal reads it as covering replacement of up to 15% of the roof deck. Adding a new roof layer is not exempt.

• Exempt: roofing replacement costing $40,000 or less (G.S. 160D-1110(c)).
• Covers replacement of up to 15% of the roof deck.
• Adding roofing (not replacing) needs a permit.
• Raleigh issued 200 matching permits in the last 12 months, with a median of 26 days from application to issue.

HVAC: Yes

North Carolina's $40,000 permit exemption does not apply to the addition, replacement or change in design of heating or air-conditioning equipment, so an HVAC replacement in Raleigh needs a permit.

• HVAC addition or replacement is excluded from the $40,000 exemption.
• Raleigh lists new HVAC units as a residential permit type.
• Licensed contractors must be named in the portal.
• Raleigh issued 61 matching permits in the last 12 months, with a median of 30 days from application to issue.

Solar Panel: Yes

Solar adds electrical wiring and equipment, which North Carolina excludes from the $40,000 permit exemption, so a rooftop solar system in Raleigh needs a permit.

• New electrical wiring and equipment are excluded from the exemption.
• Licensed electrical contractors must be named.
• Roof-mounted arrays may need structural review.
• Raleigh issued 11 matching permits in the last 12 months, with a median of 11 days from application to issue.

Fence: Yes (Zoning)

Raleigh requires a zoning permit to add or move a fence, or to replace 50% or more of one. Changing material, height or location needs a zoning permit even for a smaller replacement.

Deck: Yes

New decks need a building permit in Raleigh. Under state law, replacing only deck boards, railings, pickets or stair treads is exempt when it costs $40,000 or less.

• New decks and porches: building permit.
• Exempt: replacing decking, railings, pickets or treads up to $40,000.
• Load-bearing work always needs a permit.
• Raleigh issued 529 matching permits in the last 12 months, with a median of 24 days from application to issue.

Step-by-Step: What to Do

1. Add up the full cost of the project, materials and labor.
2. Check whether it touches structure, plumbing, electrical or mechanical systems, or adds floor area.
3. If it is a deck, confirm you are only replacing boards, guards or stair treads.
4. If any answer points to a permit, apply with the City of Raleigh (or your county).
5. Keep invoices showing cost and scope in case a buyer or inspector asks.

Work That Still Needs a Permit

• Work that changes load-bearing structure.
• Addition, replacement or change in design of plumbing, heating or air-conditioning.
• New electrical wiring for power or lighting, or changes to existing wiring.
• Adding roofing (as opposed to replacing it).

Because HVAC is excluded, a Raleigh HVAC replacement needs a permit even when it costs far less than $40,000. Solar adds wiring, so it needs one too.

How the State Fire Marshal Reads It

Guidance from the NC Office of State Fire Marshal treats replacing deck boards, railings, pickets and stair treads as exempt, and allows roof replacement with up to 15% roof-deck replacement under the exemption. Zoning permits, such as Raleigh's fence permit, are separate and still apply.

Worked Examples

These examples follow the statute and the fire marshal's guidance; local officials make the final call on a specific project.

How the $40,000 Is Counted

The threshold is the cost of the work. Splitting one project into smaller pieces to stay under the limit is risky, and the trade exclusions apply regardless of cost. Keep the contract and invoices: if the work is ever questioned, they show what was done and for how much. Contractors may also have licensing thresholds of their own; see Hiring a Licensed Contractor: Permit Rules That Depend on Licensing.

Exemption Checklist

• Is the property a single-family residence or farm building?
• Is the total cost of the work $40,000 or less?
• Does it avoid load-bearing changes?
• Does it avoid adding, replacing or redesigning plumbing, heating or air conditioning?
• Does it avoid new or changed electrical wiring?
• Is roofing being replaced rather than added?

If every answer is yes, the building permit is likely not required, though zoning permits may still apply.

Correction: New Decks Are Not Exempt

The NC Office of State Fire Marshal's guidance (October 19, 2023) is specific about decks: adding a deck is not exempt, whatever it costs. The exemption covers only the repair or replacement of deck floorboards, guard rails and stair treads, at $40,000 or less. Earlier wording on this page could be read as exempting small decks; it does not. The same guidance confirms that roof covering replacement, including up to 15% of the roof deck, is exempt, and that window and door projects over $40,000 need a permit.

Who Issues Permits in Raleigh

Residential permits in Raleigh are issued by the City of Raleigh Permit and Development Services. Its website has the current application portal, fee schedule and inspection scheduling.
