Building Permits in Durham

Durham requires a building permit for most construction, alteration, and repair work that affects structural, electrical, plumbing, or mechanical systems. For properties within Durham city limits, permits are issued by the City of Durham Department of Planning — Inspections Division under authority granted by North Carolina General Statute § 160D-1110.

Durham is part of the Research Triangle — the metropolitan region anchored by Durham, Raleigh, and Chapel Hill — and the city experiences steady residential and commercial development activity. The City-County Planning Department is a joint operation shared between the City of Durham and Durham County for land-use planning purposes, but the Inspections Division operates separately for each jurisdiction: City of Durham Inspections handles permits within city limits, while Durham County Inspections handles unincorporated areas of the county. Knowing which authority covers your property is the first step before applying.

North Carolina State Building Code — A Mandatory Statewide Standard

A defining feature of building permits in Durham — and across all of North Carolina — is that the state mandates a single statewide building code for every jurisdiction. The NC State Building Code is adopted and maintained by the NC Building Code Council and administered by the NC Department of Insurance — Office of the State Fire Marshal. Unlike states where cities may adopt and freely amend their own local building codes, North Carolina does not permit local jurisdictions to enact independent building code amendments beyond what state law explicitly authorizes. Durham enforces the NC State Building Code exactly as adopted at the state level.

The NC State Building Code family includes volumes covering:

• Structural — based on the International Building Code (IBC) with NC modifications
• Residential — based on the International Residential Code (IRC) with NC modifications
• Mechanical — based on the International Mechanical Code (IMC) with NC modifications
• Plumbing — based on the International Plumbing Code (IPC) with NC modifications
• Energy Conservation — based on the International Energy Conservation Code (IECC) with NC modifications
• Electrical — based on the National Electrical Code (NEC) with NC modifications
• Fire Prevention — based on the NC Fire Prevention Code, administered by the Office of the State Fire Marshal

When researching code requirements, always use the officially adopted NC version of each volume. NC modifications are legally mandatory and may differ materially from the base I-Code or NEC edition.

City vs. County Jurisdiction — The Critical Distinction

Durham's permitting structure has an important split that trips up applicants unfamiliar with the area:

• City of Durham Inspections Division — issues building, electrical, mechanical, and plumbing permits for all properties inside Durham city limits. Apply through the City's Citizen Self Service (CSS) portal or at the City's Inspections Division office.
• Durham County Inspections Division — issues permits for properties in unincorporated Durham County, which lies outside city limits. These areas are served by the County, not the City.

The City-County Planning Department (a joint body) handles land-use planning — zoning, site plans, and the Unified Development Ordinance (UDO) — for both jurisdictions. But the Inspections function operates separately. If you are unsure which authority applies to your parcel, confirm your property's jurisdictional status with the City or County before submitting a permit application.

When You Need a Permit

Under NC General Statute § 160D-1110, a building permit is required in Durham for:

• New construction, additions, and accessory structures (including ADUs — Accessory Dwelling Units)
• Reconstruction, alteration, or repair of existing structures when structural systems are affected
• Load-bearing wall changes, foundation work, and structural modifications
• Installation, extension, alteration, or general repair of electrical systems
• Installation, extension, alteration, or general repair of mechanical systems (HVAC, gas appliances, ductwork)
• Installation, extension, alteration, or general repair of plumbing systems
• Roofing replacement when structural work is involved or when required by code
• Swimming pools, hot tubs, and retaining walls above applicable height thresholds
• Demolition of any habitable or accessory structure
• Changes of use or occupancy classification

Minor cosmetic work — interior painting, floor covering replacement, and cabinet replacement without plumbing or electrical modifications — is generally exempt from permit requirements. When in doubt, contact the Durham Inspections Division before starting work to confirm whether a permit is needed.

Separate trade permits are typically required for each discipline (electrical, mechanical, plumbing) in addition to the primary building permit.

Citizen Self Service — Durham's Online Permit Portal

The Durham Citizen Self Service (CSS) portal at selfservice.durhamnc.gov is the City's online system for permit applications, electronic plan review, fee payment, and inspection scheduling. Through the CSS portal you can:

• Create an account and submit new permit applications
• Upload construction documents for electronic plan review
• Track application status and review comments from City staff
• Respond to correction requests and resubmit revised documents
• Pay permit fees online
• Request and track building inspections

In-person service is available at the Durham Inspections Division during regular business hours for applicants who prefer walk-in assistance or have complex submittals.

Permit Costs

Durham's permit fees are established by the City's official fee schedule, published by the Inspections Division at durhamnc.gov. Fees are typically based on the estimated construction value of the project and include separate line items for:

• Building permit fee — scales with project valuation
• Plan review fee — charged when plans must be reviewed by staff
• Trade permit fees — separate fees for electrical, mechanical, and plumbing work
• Impact and utility fees — for new construction or additions that increase demand on City water, sewer, and transportation systems
• Zoning / land use review fees — for projects requiring review under the Durham Unified Development Ordinance (UDO)

Always consult the current fee schedule directly from the Durham Inspections Division at durhamnc.gov. Do not rely on third-party fee estimates — the official schedule is the authoritative source.

Typical Timeline

Timelines vary with application volume, project complexity, and how completely the initial submittal package is prepared.

Each round of plan review comments requires a resubmittal through the CSS portal. Subsequent cycles are often faster than the first if all comments are thoroughly addressed. Submitting a complete, well-organized package on the first attempt is the single most effective way to reduce total permitting time.

The Process

1. Jurisdiction check: Confirm whether your property is within Durham city limits (City Inspections) or in unincorporated Durham County (County Inspections). This determines where you apply.
2. Zoning check: Confirm your property's zoning district under the Durham Unified Development Ordinance (UDO) and verify that the proposed use is permitted. Check for overlay districts, historic district review, or special-use requirements.
3. Plans: Prepare construction documents. Projects above applicable thresholds require drawings stamped by a licensed North Carolina architect or engineer.
4. Submit via CSS portal: Log into selfservice.durhamnc.gov, start a new permit application, and upload all required documents — application form, site plan, construction drawings, and any required engineering calculations.
5. Plan review: Durham Inspections reviewers — covering building, zoning, electrical, mechanical, plumbing, fire, and other disciplines as applicable — check the submitted plans for compliance with the NC State Building Code and the UDO.
6. Corrections: If review comments are issued, respond to all comments, revise the plans, and resubmit through the CSS portal.
7. Permit issuance: Once all reviews are approved and fees are paid, your permit is issued. Download the permit from the CSS portal.
8. Post permit on site: The issued permit card and approved plans must be kept at the job site and made available to the field inspector at every inspection.
9. Inspections: Request required inspections at each construction phase through the CSS portal or by contacting the Inspections Division.
10. Final: Pass all final inspections and, where required, obtain a Certificate of Occupancy before occupying or using the building.

Inspections

All permitted work must be inspected by Durham Inspections Division field staff to verify compliance with the NC State Building Code. Required inspections vary by project scope. Typical stages for a residential project include:

• Footing and foundation (before concrete is poured)
• Underground plumbing and electrical (before backfill)
• Framing (before insulation or sheathing is installed)
• Rough plumbing, electrical, and mechanical (before walls are closed)
• Insulation
• Drywall / sheathing
• Final building and final trade inspections

Inspection requests should be submitted through the Durham Citizen Self Service portal or by calling the Inspections Division before the daily cutoff time to be scheduled for the following business day. If work is not ready at the time of a scheduled inspection, a re-inspection fee may be assessed before the next visit is scheduled.

Common Reasons for Denial or Correction Comments

• Plans do not comply with the current NC State Building Code or NC-specific modifications
• Missing structural calculations, energy code compliance documentation (such as a Manual J load calculation or IECC compliance report), or required professional seals from a licensed NC architect or engineer
• Zoning conflicts under the Durham UDO — setbacks, height limits, lot coverage, use restrictions, or impervious surface limits
• Missing civil or site review items — stormwater management, grading plan, right-of-way encroachment, or utility service documentation
• Fire review deficiencies — fire-resistance separation, required sprinkler system, or egress path not addressed
• Historic district or overlay zone review not completed prior to permit submittal
• Submittal directed to the wrong authority (City instead of County, or vice versa)
• Incomplete application or missing supporting documents in the CSS portal
• Work commenced without a permit (a stop-work order must be resolved before the permit application can proceed)
