Do I need a permit to build a deck in Durham, NC?

Yes. In Durham, any new deck attached to your home requires a building permit, regardless of size. Freestanding decks that are 30 inches or more above grade also require a permit. Your permit application must include a site plan showing the deck's location on the lot, dimensions, distance from all property lines, and the existing house footprint. Durham's plan reviewers will check that the deck meets setback requirements for your zoning district, which typically require at least 20 to 25 feet from the rear property line for attached structures. Decks in historic overlay districts may also need a Certificate of Appropriateness before a building permit is issued. Permits are submitted through Durham's MyGovernmentOnline portal.

How much does a building permit cost in Durham, NC?

Permit fees in Durham are based on the type of project and the estimated construction value. Simple accessory structure permits, such as a small shed, may start around $100 to $150. Deck permits typically run $150 to $300 depending on size and complexity. Room additions, ADUs, and larger projects can cost several hundred dollars or more in permit fees alone, since fees scale with construction value. There may also be separate zoning review fees, tree conservation review fees, or historic district review fees depending on your project and location. The most accurate fee estimate comes from Durham's Development Services Department or the fee schedule posted on their website. Site plan preparation is a separate cost handled before you submit.

How long does it take to get a residential building permit approved in Durham?

For standard residential projects in Durham, plan review typically takes 10 to 15 business days after a complete application is submitted. Projects that require zoning variance approval, Historic Preservation Commission review, or floodplain determination can take considerably longer, sometimes six to eight weeks or more. If your application comes back with correction requests, the clock effectively resets once you resubmit, so submitting a complete and accurate application the first time is critical. Durham processes applications through the MyGovernmentOnline portal, and you can track your review status online. Pre-application meetings with Development Services staff are available for complex projects and can help identify issues before you submit.

What does Durham require on a residential site plan?

Durham's Development Services Department requires a site plan to include the lot boundaries with dimensions, the location and footprint of all existing structures, the location and footprint of the proposed structure, setback distances from all property lines, easements, driveways and walkways, the north arrow, a graphic or numeric scale, and the property address and parcel identification number. For projects in impervious surface-regulated districts, you must also include a calculation showing existing and proposed impervious coverage as a percentage of the total lot area. If significant trees or tree conservation areas exist on the lot, they must be identified. Plans do not need to be prepared by a licensed engineer or architect for most simple residential projects, but they must be accurate and drawn to scale.

Can I draw my own site plan in Durham, or do I need a licensed surveyor?

For most standard residential permits in Durham, such as decks, sheds, fences, pools, and small additions, you are not required to hire a licensed surveyor or engineer to prepare the site plan. You can draw your own site plan as long as it is accurate, drawn to scale, and includes all required elements. However, if you do not have a recent property survey, you will need to obtain one or use your deed plat to establish accurate lot dimensions and boundary locations. For more complex projects such as new construction, large additions, or ADUs, Durham may require plans stamped by a licensed North Carolina architect or engineer. Tools like Site Plan Creator make it straightforward for homeowners to produce a professional-quality site plan without specialized software.

What are the setback requirements for residential properties in Durham, NC?

Setback requirements in Durham vary by zoning district. In typical residential zones, front setbacks range from 15 to 25 feet, side setbacks are generally 5 to 8 feet for interior lots, and rear setbacks are usually 20 to 25 feet for principal structures. Corner lots typically require a larger side setback along the street-facing side, often 10 feet. Detached accessory structures like sheds and ADUs are often allowed closer to the rear and side property lines, with minimums as low as 5 feet in many districts. Overlay districts, historic districts, and watershed protection areas can impose additional setback or buffer requirements. Always verify your specific parcel's setbacks using Durham's GIS tools or by contacting Development Services, since individual lot conditions and easements can affect what applies.

Where do I submit a site plan and permit application in Durham, NC?

Durham processes most residential permit applications online through the MyGovernmentOnline (MGO) portal, accessible through the City of Durham Development Services website at durhamnc.gov. You create an account, select the appropriate permit type, upload your site plan and supporting documents, and pay the application fee electronically. In-person submissions are also accepted at the Development Services counter located at 101 City Hall Plaza in downtown Durham, but online submission is generally faster and allows you to track your application status in real time. For questions before you submit, Development Services staff are available by phone at (919) 560-4144 or by email. Pre-application consultations are recommended for complex or unusual projects.

What happens if I build without a permit in Durham, NC?

Building without a required permit in Durham can result in serious consequences. If an unpermitted structure is discovered, the city can issue a stop-work order immediately halting any ongoing construction. You may be required to obtain a retroactive permit, which often involves additional inspections and fees. In some cases, Durham can require you to remove or demolish unpermitted work that cannot be brought into compliance. Civil penalties and fines can also be assessed. Unpermitted additions or structures can complicate the sale of your home, since buyers' lenders and inspectors routinely flag permit history issues. Insurance claims related to unpermitted work may also be denied. The safest and least expensive path is always to obtain the proper permit before construction begins.

Are ADUs allowed in Durham, NC, and what permits do they require?

Yes, accessory dwelling units are permitted in Durham and the city has actively updated its zoning rules to encourage ADU construction as part of its housing affordability strategy. Both attached ADUs, such as basement apartments or additions, and detached ADUs, such as backyard cottages, are allowed in most residential zoning districts. You must obtain a building permit for any ADU, and your application must include a site plan showing the ADU's location, setbacks, footprint, and relationship to the primary dwelling. Detached ADUs typically must meet a minimum 5-foot rear and side setback. There are also size limits based on the primary dwelling's square footage. Owner-occupancy requirements have been relaxed under recent UDO updates. Contact Durham Development Services for the current ADU standards applicable to your specific zoning district.

Does Durham have floodplain rules that affect my site plan?

Yes. Portions of Durham lie within FEMA-designated Special Flood Hazard Areas, particularly along the Eno River, Ellerbe Creek, Little River, and other waterways. If your property is in or near a flood zone, your site plan must identify the floodplain boundary and may need to show the Base Flood Elevation. Construction within a Special Flood Hazard Area requires compliance with Durham's floodplain management ordinance, which may mandate that finished floor elevations be raised above the base flood elevation and that an elevation certificate be prepared by a licensed surveyor. Certain types of development may be prohibited outright in the floodway. You can check your property's flood zone designation using FEMA's Flood Map Service Center at msc.fema.gov, and Durham's Development Services staff can advise on local floodplain requirements.

Site Plan Requirements in Durham, NC (Permit Guide)

By Site Plan Creator Team • May 20, 2026

Site plan requirements for residential properties in Durham, North Carolina

Residential Site Plans and Permits in Durham, NC

Durham is one of North Carolina's fastest-growing cities, and that growth means more homeowners than ever are tackling backyard projects, home additions, accessory dwelling units, and structural improvements. Whether you live near the vibrant Ninth Street corridor, in a quiet Northgate Park neighborhood, or out toward Research Triangle Park, the City of Durham requires a residential site plan as part of nearly every building permit application. Getting that document right from the start saves you time, money, and the frustration of a rejected submittal.

What Is a Residential Site Plan and Why Does Durham Require One?

A residential site plan is a scaled, bird's-eye drawing of your property that shows the lot boundaries, existing structures, proposed construction, setbacks from property lines, driveways, easements, and other site features. Durham's Development Services Department uses it to verify that your project complies with the Unified Development Ordinance (UDO), which governs land use, zoning, and construction standards across the city.

Without an approved site plan, Durham's plan reviewers cannot confirm that your structure respects required setbacks, stays within impervious surface limits, avoids easements, or meets neighborhood-specific zoning rules. A missing or inaccurate site plan is one of the most common reasons permit applications are delayed or denied.

Which Projects Require a Permit (and a Site Plan) in Durham?

Durham's Development Services Department requires a building permit, and therefore a site plan, for a broad range of residential projects. Common triggers include:

Decks and porches: Any new or replacement deck attached to the house, or a freestanding deck above 30 inches, requires a permit.
Accessory structures and sheds: Sheds larger than 144 square feet require a permit. Smaller sheds may still need zoning approval depending on placement.
Swimming pools and hot tubs: In-ground and above-ground pools deeper than 24 inches require a permit and site plan showing required setbacks and barrier fencing.
Fences: Fences over six feet in height require a permit. Fences in front yards or within historic overlay districts may have additional restrictions.
Room additions and sunrooms: Any expansion of the home's footprint requires a full permit package including a site plan.
Accessory Dwelling Units (ADUs): Durham actively encourages ADU construction under its updated zoning rules, but both attached and detached ADUs require permits and a detailed site plan.
Driveways and impervious surfaces: New or expanded driveways may require a zoning permit and must comply with Durham's impervious surface limits, which vary by zoning district.
Garage conversions: Converting an attached or detached garage to living space requires a permit and an updated site plan.

For a full list of permit triggers, visit the City of Durham Development Services Department.

Zoning Quirks and Local Considerations in Durham

Durham's Unified Development Ordinance is detailed, and several local factors can complicate an otherwise straightforward permit application.

Historic Districts: Durham has several locally designated historic districts, including Morehead Hill, Watts-Hillandale, and Old West Durham. Projects in these areas require a Certificate of Appropriateness from the Historic Preservation Commission before a building permit is issued. Site plans for historic district projects must show how the new construction relates to the existing structure and streetscape.

Floodplain Regulations: Portions of Durham lie within FEMA-designated Special Flood Hazard Areas, particularly along the Eno River, Ellerbe Creek, and other waterways. If your property is in or near a floodplain, your site plan must show the Base Flood Elevation, and construction may require elevation certificates. Check your property's flood zone status at FEMA's Flood Map Service Center.

Tree Conservation: Durham's UDO includes tree conservation area requirements. Significant trees and tree save areas must be identified on site plans, and disturbing them without approval can result in stop-work orders and fines.

Impervious Surface Limits: Many Durham zoning districts cap the percentage of a lot that can be covered by impervious surfaces such as roofs, driveways, patios, and walkways. Your site plan must calculate and display the existing and proposed impervious surface coverage.

Watershed Overlay Districts: Properties in the Falls Lake or Jordan Lake watershed protection areas face stricter impervious surface limits and buffer requirements along streams and wetlands.

Typical Setback Requirements in Durham

Setbacks in Durham vary by zoning district, but the following ranges are typical for standard residential zones:

Front setback: 15 to 25 feet from the front property line, depending on the zoning district and the established setback line on the street.
Side setback: 5 to 8 feet for interior lots; corner lots often require a 10-foot side setback along the street side.
Rear setback: 20 to 25 feet from the rear property line for principal structures.
Accessory structures: Detached sheds, garages, and ADUs typically require a minimum 5-foot rear and side setback, though some districts allow placement closer to the rear line.

Always verify setbacks for your specific parcel and zoning district using Durham's online GIS mapping tool or by contacting Development Services directly, since overlay districts, easements, and lot size can all affect the numbers.

How to Submit a Permit Application in Durham

Durham processes most residential permit applications through its online portal. Here is a general overview of the process:

Gather your documents. Prepare your site plan, construction drawings, property survey (if available), and any required forms.
Submit online. Durham uses the MyGovernmentOnline (MGO) portal for permit applications. Create an account, select the correct permit type, and upload your documents.
Pay the application fee. Fees are based on project type and estimated construction value. Residential permits typically range from around $100 for simple accessory structures to several hundred dollars or more for additions and ADUs.
Plan review. Durham's plan reviewers check for zoning compliance, building code compliance, and site plan accuracy. Review times for standard residential projects generally run 10 to 15 business days, though complex projects or those requiring historic commission review can take longer.
Respond to corrections. If reviewers request changes, you will receive a correction notice through the portal. Resubmit revised documents promptly to avoid losing your place in the queue.
Permit issuance and inspections. Once approved, download your permit, post it on site, and schedule required inspections through the portal as work progresses.

For code questions or pre-application guidance, the North Carolina Department of Insurance Office of State Fire Marshal publishes the state's adopted building codes, which Durham enforces.

Common Reasons Durham Permit Applications Are Rejected

Understanding why applications fail helps you avoid the same mistakes:

Missing or incorrect setback dimensions: Reviewers will reject plans that do not clearly label all setback distances from proposed structures to property lines.
No scale or north arrow: Site plans must be drawn to scale (or include a graphic scale bar) and show a north arrow.
Impervious surface calculation missing: If your district has an impervious surface cap, failing to include the calculation is an automatic correction request.
Easements not shown: Utility, drainage, and access easements must appear on the site plan. Building within an easement is not permitted.
Inconsistent dimensions: If the footprint shown on the site plan does not match the dimensions on the construction drawings, reviewers will flag the discrepancy.
Wrong permit type selected: Choosing the wrong application category in the portal can route your application to the wrong review queue and cause significant delays.

How to Create a Site Plan in Durham

Confirm Your Permit Requirements: Before drawing anything, contact Durham's Development Services Department or check the City of Durham website to confirm whether your specific project requires a building permit and site plan. Project type, size, location, and zoning district all affect what is required. Projects in historic overlay districts or flood zones may have additional review steps. Getting clarity upfront prevents wasted effort on documents you may not need, or worse, starting construction without the permits you do need.
Gather Your Property Documents: Collect your property survey, deed plat, or tax map to establish accurate lot dimensions and boundary locations. You will also need to identify your zoning district, any easements on the property, and whether you are in a historic district, watershed overlay, or FEMA flood zone. Durham's online GIS mapping tool can help you locate easements and overlay boundaries. Having these documents ready before you start your site plan ensures your measurements and setback calculations are based on accurate information.
Prepare Your Site Plan: Using your property documents, create a scaled site plan that shows lot boundaries with dimensions, all existing structures, the proposed structure's footprint and location, setback distances from all property lines, driveways, easements, a north arrow, and a scale bar. If your zoning district has impervious surface limits, calculate and display the existing and proposed impervious coverage. Site Plan Creator guides you through each required element so your plan meets Durham's Development Services standards without requiring CAD expertise or a licensed surveyor for most standard residential projects.
Submit Your Application Online: Create an account in Durham's MyGovernmentOnline (MGO) portal and select the correct permit type for your project. Upload your completed site plan, construction drawings, and any other required documents. Pay the application fee electronically. Double-check that all required fields are complete and all documents are legible before submitting, since incomplete applications are returned and restart the review clock. Keep your application confirmation number for tracking purposes.
Respond to Plan Review Comments: Durham's plan reviewers will examine your application for zoning compliance, building code compliance, and site plan accuracy. If corrections are needed, you will receive a notice through the MGO portal detailing what must be changed. Respond promptly with revised documents. Common correction requests involve missing setback dimensions, impervious surface calculations, or easement locations. Addressing all comments thoroughly in your resubmittal avoids additional rounds of review and gets your permit issued faster.
Receive Your Permit and Schedule Inspections: Once Durham approves your application, download and print your permit. Post it visibly on the job site as required. Schedule required inspections through the MGO portal at the appropriate construction milestones, such as footing, framing, and final inspections. Do not cover work that has not yet been inspected. After all inspections pass and the project receives a final approval, your permit is closed and your project is officially complete and on record with the city.
