Charlotte Shed & Detached Garage Site Plan Requirements

Example layout only. Required setbacks and permit conditions vary by property, zoning district and project.

Adding a shed or detached garage to a Charlotte property may seem straightforward, but the proposed structure still needs to fit within the property’s zoning, setback, drainage and access requirements.

Permit reviewers may need to see exactly where the new building will sit, how large it will be, how close it will be to the property lines and whether it affects an easement, drainage feature, driveway or protected tree.

A clear Charlotte shed and detached garage site plan presents this information in one easy-to-read drawing. It shows the proposed accessory structure in relation to the existing house, lot boundaries and other important property features.

This guide explains when City and County permits may be required, what the site plan should show and which common issues can delay approval.

Does a Shed Require a Permit in Charlotte?

The permit path generally depends on the size of the proposed shed or accessory structure.

The City of Charlotte states that an accessory structure measuring 12 feet or less in every dimension requires a City Zoning Use Permit. This review confirms that the proposed location complies with applicable Charlotte Unified Development Ordinance requirements.

When any dimension exceeds 12 feet, a Mecklenburg County building permit is generally required. The project is also included among the residential projects requiring City of Charlotte Land Development Individual Residential Lot review, commonly called LDIRL review.

The 12-foot threshold can apply to the building’s width, depth or height. Applicants should therefore confirm all three measurements before choosing the permit type.

Does a Detached Garage Require a Permit?

A detached garage will normally require both City and County review.

The City includes garages and detached accessory structures greater than 12 feet in any dimension among projects requiring LDIRL review. Mecklenburg County separately administers the building permit and building-code review.

The reviews serve different purposes:

• City of Charlotte: Reviews zoning, setbacks, lot coverage, drainage, stormwater, urban forestry and other applicable land-development requirements.
• Mecklenburg County: Reviews the building design, foundation, framing, electrical work and other applicable construction-code requirements.

Applicants may be able to submit the City and County applications around the same time, but City approval is generally needed before final County building-permit approval.

What Is a Shed or Detached Garage Site Plan?

A site plan is an overhead drawing showing the layout of the property and the proposed location of the new accessory structure.

It helps reviewers understand how the shed or garage fits on the lot without having to interpret several separate sketches.

The site plan is different from the building-construction plans.

A larger shed or detached garage permit package may require both types of drawings.

What Should the Site Plan Show?

Charlotte’s residential accessory-structure materials instruct applicants to show the property boundaries, existing and proposed buildings and the distances between buildings, property lines and other structures.

A useful shed or garage site plan commonly includes:

• The complete property boundaries
• Lot dimensions
• The property address and adjoining street
• The existing house footprint
• The proposed shed or detached garage footprint
• The length and width of the proposed building
• Roof overhangs when they affect the structure footprint
• Distances from the building to each nearby property line
• Distance between the accessory structure and the house
• Distance from other garages, sheds, decks, pools or structures
• Front, side and rear setback lines
• The existing and proposed driveway
• The garage-door location and vehicle-access route
• Walkways, patios and other paved areas
• Utility, access and drainage easements when known
• Visible drainage features that may be affected
• Protected trees or tree-save areas when applicable
• A north arrow and drawing scale

The drawing should clearly distinguish between existing and proposed work. Reviewers should not have to guess which building is being added.

The City’s accessory-structure form also says that a separate application and plot plan may be required for each building. A property owner proposing both a garage and a separate shed should confirm whether separate submissions are necessary.

Property Lines and Setback Measurements

The property boundaries are the starting point for determining where a shed or garage can be placed.

A site plan should show the shortest distance from the proposed structure to the relevant side and rear property lines. The distance should normally be measured from the part of the structure closest to the boundary.

Roof eaves and overhangs should be considered when they extend beyond the wall footprint and affect the required separation.

Do not automatically assume that a fence, hedge, driveway edge or maintained lawn line represents the legal property boundary. These visible features may not follow the recorded lot line.

Useful property documents include:

• A current boundary survey
• A recorded subdivision plat
• A previously approved site plan
• Recorded easement documents
• Charlotte Explorer and Mecklenburg County property records for preliminary research

A survey may be necessary when the proposed building is close to a property line or the boundary location is uncertain.

Are Charlotte Accessory-Structure Setbacks Always the Same?

No. There is not one universal setback that applies to every shed and detached garage in Charlotte.

The required location can depend on:

• The property’s zoning district
• The size and height of the accessory structure
• Whether the lot is an interior, corner or through lot
• The established front, side and rear setbacks
• The height of the principal house
• The location of recorded easements
• Floodplain, watershed or stormwater conditions
• Historic-district requirements
• Protected trees and tree-save areas
• Subdivision covenants or HOA restrictions

Current City permit materials summarize that certain accessory structures located within an established side or rear setback may be permitted at least three feet from a lot line. However, taller structures and properties subject to other restrictions may require substantially greater setbacks.

For example, the City materials state that an accessory structure measuring 24 feet or taller—or a shorter accessory structure that is taller than the principal building—may be subject to a minimum 15-foot rear setback and the zoning district’s required side setback.

These standards should not be treated as a substitute for a property-specific zoning review. When another applicable rule is more restrictive, the stricter standard may control.

Property owners should review the current

Charlotte Unified Development Ordinance

and confirm the applicable setbacks before finalizing the building location.

Structure Size and Lot Coverage

Reviewers may consider more than the distance between the proposed building and the property boundaries.

The project may also be reviewed for lot coverage, impervious area and the total size of accessory structures on the property.

Charlotte’s current accessory-structure permit materials state that, for residential properties, the combined square footage of accessory structures other than ADUs generally cannot exceed the heated first-floor area of the principal building.

Existing garages, sheds and other enclosed accessory buildings may therefore affect how much additional accessory-building area can be added.

The application may also request the amount of proposed impervious or built-upon area. This can include the new building footprint and, depending on the project, additional driveway or paved surfaces.

Detached Garage Driveway Access

A detached garage site plan should show how vehicles will reach the building.

Important garage-access information may include:

• The existing driveway
• A proposed driveway extension
• The garage-door location
• The direction vehicles will enter the garage
• The width of the access route
• Nearby sidewalks or public rights-of-way
• Side-street or alley access when applicable
• Drainage features crossed by the driveway

A garage door facing a side street, alley or different frontage may trigger additional access or transportation review.

Any proposed driveway change should be shown clearly rather than leaving reviewers to assume that the existing access will remain unchanged.

Easements and Utility Locations

Easements can limit where a shed or garage may be placed, even when the structure appears to meet the zoning setback.

Common easements include:

• Utility easements
• Drainage easements
• Public stormwater easements
• Sewer easements
• Access easements

Charlotte’s permit materials state that identifying the location or existence of drainage, water and sanitary-sewer facilities and easements remains the property owner’s responsibility.

A building should not be positioned over an easement without confirming that construction is allowed and obtaining any necessary approval.

Recorded plats, surveys, title documents and Register of Deeds records may help identify easements affecting the lot.

Drainage and Stormwater Review

A shed or detached garage changes the surface of the property and may redirect rainwater from the roof onto the surrounding ground.

Charlotte Storm Water Services may review projects to determine whether the proposed work:

• Conflicts with a public stormwater easement
• Affects an existing ditch, swale, pipe or catch basin
• Changes an established drainage path
• Adds impervious area
• Requires a storm-drainage connection
• Is located within or near a floodplain
• Could direct runoff toward a neighboring property

The City states that reviewers seek to prevent buildings and retaining walls from being constructed within City or public stormwater easements.

Visible drainage features close to the proposed building should be shown on the site plan. More complicated properties may require grading, drainage or engineering information beyond a basic site plan.

Trees and Urban-Forestry Requirements

Urban Forestry review may apply when a proposed garage or shed affects protected trees, right-of-way trees, heritage trees or designated tree-save areas.

Charlotte identifies different Urban Forestry review tiers for residential projects such as garages. The applicable tier depends on whether protected trees or tree-save areas are present.

A site plan may need to show trees when:

• A tree is close to the proposed foundation
• Construction access may affect the tree’s root area
• A driveway extension passes near a tree
• A tree is proposed for removal
• The property contains protected or required trees
• The lot contains a designated tree-save area

The City determines which tree information is needed based on the project type, location and existing site conditions.

Shed vs Detached Garage Site Plan Details

Garages With Living Space or an ADU

A garage containing a bedroom, kitchen, bathroom or independent living area may be treated differently from a standard storage or vehicle garage.

Charlotte defines an accessory dwelling unit, or ADU, as a separate dwelling unit associated with a principal residence. A detached garage containing an ADU must comply with additional UDO standards and permit requirements.

The plans may need to address:

• The permitted size of the ADU
• The relationship to the principal residence
• Driveway and parking arrangements
• Building height
• Setbacks
• Floor plans and elevations
• Utility connections
• Fire and building-code requirements

Do not describe a building as a standard detached garage if it will be used as an independent dwelling. The intended use should be accurately disclosed during the permit process.

Other Structures That Should Be Shown

Reviewers need to understand the complete lot layout, not only the proposed shed or garage.

Existing improvements that may need to appear include:

• The main house
• Existing sheds and detached garages
• Decks and porches
• Swimming pools
• Carports
• Patios and paved areas
• Retaining walls
• Driveways and parking areas
• Walkways and sidewalks

These features can affect building separation, lot coverage, access and the amount of remaining space available for another accessory structure.

Common Site Plan Mistakes

A shed or detached garage plan may need corrections when important information is missing, unclear or inconsistent.

Common problems include:

• Leaving out one or more property lines
• Failing to show lot dimensions
• Not showing the proposed building dimensions
• Leaving out the building height
• Not showing distances to property lines
• Failing to show the distance to the existing house
• Using a fence as the assumed property boundary
• Leaving out roof overhangs
• Not showing the garage driveway or access route
• Ignoring a recorded easement
• Failing to show nearby drainage features
• Leaving existing accessory structures off the drawing
• Using conflicting dimensions on different plans
• Submitting an unscaled or difficult-to-read sketch
• Describing an ADU as a standard garage or shed

Clear labels and consistent measurements can reduce unnecessary questions during review.

How the Permit Process Generally Works

The general process may include:

1. Confirm the structure’s width, depth and height.
2. Determine whether the project follows the Zoning Use Permit or LDIRL and building-permit route.
3. Confirm the property zoning and applicable setbacks.
4. Gather the survey, recorded plat and available property documents.
5. Prepare the site plan and applicable construction drawings.
6. Submit the City application through Accela Citizen Access.
7. Submit the Mecklenburg County building-permit application when required.
8. Respond to review comments and upload revised plans when requested.
9. Obtain the required approvals before beginning construction.
10. Schedule applicable inspections during and after construction.

The City currently describes a gateway review followed by detailed review for LDIRL projects. Missing forms, unclear plans or zoning conflicts can result in another review cycle.

Information Needed to Prepare the Site Plan

Before ordering your Charlotte shed or garage site plan, gather as much of the following information as possible:

• The property address
• A boundary survey or recorded plat
• The proposed building width and depth
• The proposed building height
• The roof-overhang dimensions
• The proposed location on the property
• Distances to nearby property lines
• Distance to the existing house
• The garage-door location
• Driveway or vehicle-access information
• Photos of the proposed construction area
• Manufacturer plans or contractor drawings
• Any City or County review comments already received

Accurate source information helps produce a clearer and more useful site plan.

Charlotte Shed and Garage Site Plan FAQs

Does a small shed need a permit in Charlotte?

The City states that an accessory structure measuring 12 feet or less in every dimension requires a Zoning Use Permit. A larger structure generally requires City LDIRL and Mecklenburg County building-permit review.

Does a detached garage need a site plan?

Yes, a site plan is normally needed to show the garage location, dimensions, property-line distances, relationship to the house and driveway access.

Can I place a shed three feet from the property line?

Some accessory structures may qualify for a three-foot separation under certain UDO conditions, but the rule is not universal. Structure height, zoning, lot type, easements and other restrictions can require a greater setback.

Can I use a fence as the property line?

A fence should not automatically be treated as the legal boundary. Use a survey or recorded plat when accurate property-line information is needed.

Should the garage driveway appear on the site plan?

Yes. The plan should show the existing or proposed driveway, garage-door orientation and how vehicles will reach the building.

Do roof overhangs affect the setback?

Roof overhangs can affect the complete building footprint and the distance to a property line. They should be included when they extend toward a required setback or boundary.

Does a garage with an apartment follow the same rules?

No. A garage containing an accessory dwelling unit must comply with additional Charlotte ADU, zoning and building-permit requirements.

Can USA Site Plans revise the plan after permit comments?

Yes. When requested revisions fall within the purchased drafting service, the drawing can be updated using written comments supplied by the reviewing authority.
