Do you need a site plan for a driveway permit? In many cities and counties, the answer is yes—especially when you are adding a new driveway, widening or relocating an existing driveway, changing the curb cut, creating access from an alley or performing work inside the public right-of-way.

A driveway permit site plan is a scaled, top-down drawing of the property. It shows where the proposed driveway will be located in relation to the house, garage, property boundaries, street, sidewalk, curb, parking area, easements, utilities, drainage and other important site features.

Permit rules vary significantly. Some jurisdictions require approval for every new or modified driveway. Others distinguish between work on private property and work inside the public right-of-way. Repairs made in the same location and dimensions may also follow a different process from a new driveway or widened curb cut. [1][2][3][4]

When Is a Driveway Permit Usually Required?

You are more likely to need a driveway, curb-cut or right-of-way permit when you are:

• Building a new driveway
• Widening an existing driveway
• Relocating the driveway entrance
• Adding a second driveway
• Changing the curb cut or driveway apron
• Converting landscaping into parking or paving
• Paving an existing gravel parking area
• Adding access to a new garage or carport
• Connecting to a public alley
• Crossing a sidewalk, verge or drainage channel
• Changing the driveway slope or profile
• Installing a culvert beneath a rural driveway
• Working near a street tree, utility pole or stormwater inlet
• Connecting to a state highway or another controlled road

Portland states that installing or changing a driveway always requires a permit, including driveways accessing an alley, gravel street or right-of-way that is not currently passable. [1]

Seattle requires a curb-cut permit when a new driveway is created through an existing sidewalk curb. The permit may be part of a larger building permit or issued separately. [2]

Minneapolis requires a plan-review request before a driveway is changed in a public area. After the plans are approved, the applicant can proceed with the required sidewalk-inspection permit. [3]

Austin requires transportation review when a driveway approach in the right-of-way will be installed, relocated, removed or repaired. This includes access to paved streets, unpaved streets, streets without curb and gutter, and adjacent alleys. [4]

Driveway, Driveway Apron and Curb Cut: What Is the Difference?

These terms are related, but they do not always describe the same part of the project.

Private Driveway

The private driveway is generally the section located inside the property boundaries. It connects the front property line to the garage, carport, parking pad or other vehicle area.

Driveway Apron or Approach

The driveway apron or driveway approach is the transition between the street and the private driveway. It may cross:

• The public sidewalk
• A planting strip or verge
• The curb and gutter
• An open drainage channel
• Other land inside the public right-of-way

Curb Cut

The curb cut is the opening or lowered section of curb that allows vehicles to leave the roadway and enter the driveway.

Seattle explains that curb-cut permits are overseen because the curb is located in the city right-of-way. Minneapolis describes a curb cut, or drive apron, as the driveway connection to a public street. [2][5]

A zoning or building approval for a garage does not necessarily approve the driveway apron or curb cut. Work inside the right-of-way often requires separate transportation or public-works approval.

Does Every Driveway Project Need the Same Permit?

No. The required approval depends on the scope of work.

New Driveway

A completely new driveway commonly requires review of:

• Driveway location
• Curb-cut width
• Distance from intersections
• Street-tree and utility conflicts
• Parking and manoeuvring
• Drainage
• Lot coverage or impervious area

Driveway Widening

Widening can require approval even when the original driveway is legal. The new portion may affect:

• The curb opening
• Sidewalk
• Property-line clearance
• Street parking
• Utility assets
• Landscaping requirements
• Stormwater runoff

Driveway Relocation

Moving the driveway usually means closing or restoring the old access and obtaining approval for the new one.

The plan may need to show:

• Existing driveway to be removed
• Existing curb cut to be closed
• Proposed driveway location
• Proposed curb cut
• Restored sidewalk, curb and landscaping

Repair or Replacement

Replacing a driveway in the same location and dimensions may follow a simpler process in some jurisdictions. However, repairing the driveway apron, curb or sidewalk can still require a right-of-way or inspection permit.

Austin notes that repairs or replacements made in the same location may have different documentation requirements from a new or altered approach. Portland also requires permits for voluntary repairs to driveways and curbs within the public right-of-way. [9][10]

What Is a Driveway Permit Site Plan?

A driveway permit site plan shows the entire access route between the road and the property’s parking area.

It allows the reviewer to understand:

• Where the driveway will enter the property
• How wide and long it will be
• How it connects to the garage or parking area
• Whether it crosses a sidewalk or drainage channel
• Whether it conflicts with utilities or street trees
• How close it is to the property lines
• Whether vehicles can park and manoeuvre safely
• How stormwater will flow around the paving
• Whether the project affects public property

Minneapolis defines a construction site plan as a drawing showing the property lines, existing structures and the location of the proposed change. Austin describes a site plan as a detailed drawing showing improvements such as buildings, landscaping, parking areas, driveways, detention facilities and utilities. [6][7]

What Should a Driveway Permit Site Plan Show?

The exact checklist varies by jurisdiction, but a useful residential driveway site plan commonly includes the following details.

Property Boundaries and Lot Dimensions

Show the complete legal outline of the property.

Include:

• Front property line
• Side property lines
• Rear property line
• Length of each boundary
• Lot width and depth
• Irregular or angled boundaries
• Property address

The boundaries provide the reference points for locating the driveway and measuring any required clearances.

Do not assume that a fence, hedge or edge of pavement marks the legal property line. A licensed survey may be needed when the proposed paving is close to a boundary or the property corners cannot be confirmed.

Street and Road Information

Show the street adjoining the driveway.

Include:

• Street name
• Edge of pavement
• Curb and gutter
• Road shoulder
• Public right-of-way
• Road centerline where relevant
• Side street on a corner lot
• Alley where applicable

For a corner property, show both street frontages and the distance from the proposed driveway to the intersection.

Existing House and Structures

Show the existing house and structures that affect the driveway layout.

These may include:

• House
• Garage
• Carport
• Shed
• Accessory dwelling unit
• Deck or patio
• Retaining walls
• Swimming pool
• Fences and gates

The plan should make clear where the driveway starts, where it ends and which parking area or structure it serves.

Existing Driveway and Curb Cut

Show the current driveway, even if it will be removed or changed.

Use clear labels such as:

• Existing Driveway to Remain
• Existing Driveway to Be Widened
• Existing Driveway to Be Removed
• Existing Curb Cut to Be Closed

Showing the existing condition helps reviewers understand exactly what is changing.

Proposed Driveway Layout

Clearly label the new paving:

Proposed Driveway

Use a bold outline, hatching or different shading to distinguish the proposed work from the existing driveway and other paved surfaces.

Show the complete path from:

• Street or alley
• Across the sidewalk or verge
• Through the property boundary
• To the garage, carport or parking pad

Driveway Width and Length

Show written driveway dimensions.

Measure the width at important points, including:

• At the street or curb
• At the front property line
• Inside the property
• At the garage or carport
• At the narrowest section
• At any turning or parking area

Also show the approximate total length of the proposed paving.

Do not assume there is one national standard driveway width. Local standards may depend on:

• One-way or two-way use
• Single-car or double-car access
• Number of homes served
• Street classification
• Zoning district
• Fire-department access needs

Curb-Cut or Apron Width

Show the width of the driveway opening at the street.

Include:

• Curb-cut width
• Driveway-apron width
• Flared or tapered sections
• Distance from the curb cut to property lines
• Distance to other driveways
• Distance to the intersection

Minneapolis driveway-approach guidance asks applicants to show the size and location of the proposed apron in relation to the street, public sidewalk, property lines and surrounding structures or street assets. [8]

Sidewalk and Pedestrian Route

Show the public sidewalk where the driveway crosses it.

Include:

• Sidewalk width
• Sidewalk alignment
• Driveway crossing
• Pedestrian route
• Proposed sidewalk reconstruction
• Any curb ramp nearby

The driveway should not create an abrupt step, excessive cross-slope or another obstacle for pedestrians.

Minneapolis requires a sidewalk inspection permit for work involving driveway aprons, curbs or gutters. [11]

Driveway Setbacks and Clearances

Show the shortest distance from the proposed driveway or parking surface to:

• Side property lines
• House
• Garage or carport
• Retaining walls
• Fences
• Utility equipment
• Other paved areas

Some zoning codes regulate how much of the front or side yard may be paved and where parking can be located.

Use the local zoning rules rather than copying a setback from another city’s plan.

Garage, Carport and Parking Connection

The driveway should align with the area it serves.

Show:

• Garage-door location and width
• Carport opening
• Parking-pad outline
• Driveway centerline where helpful
• Vehicle direction
• Clearance beside walls or posts

You may also find our guides on garage permit site plans and carport permit site plans helpful.

Parking and Manoeuvring Areas

Show where vehicles will park and how they will turn.

The site plan may include:

• Parking-space dimensions
• Turning bay
• Hammerhead turnaround
• Reversing area
• Vehicle swept path
• Clearance from buildings, fences and walls

Seattle advises applicants to research driveway width, slope, manoeuvring space, sight triangles and curb-cut requirements when creating vehicle access to parking. [12]

Driveway Gradient and Profile

A steep or uneven driveway may need more than a top-down site plan.

A driveway profile or longitudinal section can show:

• Street elevation
• Top of curb
• Gutter or channel elevation
• Sidewalk elevation
• Property-line elevation
• Driveway slopes
• Grade transitions
• Garage slab or parking-pad elevation

The profile helps reviewers check whether vehicles are likely to scrape at the curb, sidewalk, driveway crest or garage entrance.

Portland requires a driveway-profile cross section when applicable for a driveway-design exception. [13]

Sight Distance and Sight Triangles

Drivers should be able to see pedestrians, cyclists and approaching traffic before entering the street.

Show anything that may block visibility, including:

• Solid fences
• Retaining walls
• Hedges and landscaping
• Utility cabinets
• Buildings
• Street trees
• Sharp changes in ground level

Where required, show the driveway sight triangle or sight-distance area.

Seattle’s parking guidance specifically identifies driveway sight triangles as an item applicants should research. [12]

Street Trees and Landscaping

Show street trees and significant landscaping near the proposed access.

Include:

• Tree-trunk location
• Approximate canopy where relevant
• Distance from tree to driveway
• Tree-protection zone
• Trees proposed for removal
• Landscaping to be restored

A new driveway may not be approved in the preferred location if it conflicts with a protected street tree or its root system.

Utility Poles and Public Assets

Show public and utility features close to the driveway.

These may include:

• Power poles
• Streetlights
• Fire hydrants
• Water meters
• Utility cabinets
• Telecommunications pits
• Traffic signs
• Bus stops
• Mailboxes

The driveway location may need to change when it conflicts with an asset that cannot be relocated.

Minneapolis driveway-approach guidance asks for dimensions to surrounding features such as fences, fire hydrants and other relevant objects. [8]

Stormwater Inlets and Drainage Infrastructure

Show drainage infrastructure near the driveway.

This may include:

• Stormwater inlet
• Catch basin
• Curb drain
• Open ditch
• Culvert
• Drainage channel
• Stormwater pipe
• Drainage easement

Charlotte’s individual residential-lot review process checks for standard residential driveways and conflicts with existing catch basins. It also reviews drainage and flooding issues where applicable. [14]

Driveway Drainage

A driveway can redirect a substantial amount of stormwater.

Show:

• Direction of surface-water flow
• Existing and proposed grades
• Trench or channel drains
• Stormwater pits
• Swales
• Culverts
• Connection to an approved drainage system

The driveway should not direct water into the garage, across the sidewalk in a hazardous way or onto neighbouring property.

Impervious Area and Lot Coverage

New concrete, asphalt or paving can increase the property’s impervious area.

Where required, the plan may show:

• Total lot area
• Existing house and roof area
• Existing driveway and patios
• Proposed driveway area
• Total proposed impervious area
• Remaining landscaped or permeable area

Impervious-area calculations can affect stormwater review, zoning compliance and drainage requirements.

Easements

Show all known easements affecting the driveway area.

Common examples include:

• Utility easement
• Drainage easement
• Access easement
• Sewer easement
• Stormwater easement
• Shared-driveway easement

Label the easement width and purpose.

A driveway may sometimes cross an easement, but construction must not interfere with infrastructure, legal access or maintenance rights.

Underground Utilities

Show known services beneath or near the proposed paving.

These can include:

• Water service
• Sewer line
• Gas service
• Electrical service
• Telecommunications line
• Stormwater pipe

Before excavation begins, underground utilities should be located using the appropriate local utility-location service.

Rural Driveways and Culverts

A driveway on an uncurbed rural road may need to cross an open ditch or table drain.

The site plan may need to show:

• Road edge
• Road shoulder
• Ditch or channel
• Culvert location
• Culvert size and length
• Headwalls or end treatments
• Direction of drainage flow
• Driveway surface and width

A civil engineer or road authority may need to determine the correct culvert size.

Retaining Walls and Grading

Show walls and earthwork needed to support the driveway.

Include:

• Existing retaining walls
• Proposed retaining walls
• Wall height
• Cut and fill areas
• Driveway-edge protection
• Drainage behind the walls
• Distance to property lines

Retaining walls may need separate building permits or structural engineering depending on their height, location and loading.

Gates and Front Fences

Where a driveway passes through a gate or fence, show:

• Gate location
• Clear opening width
• Gate-swing direction
• Distance from the sidewalk or street
• Front-fence location
• Pedestrian gate

The gate should not swing across the public sidewalk or require a vehicle to stop in an unsafe position while it is opened.

North Arrow, Scale and Drawing Information

The plan should include:

• North arrow
• Recognized drawing scale
• Property address
• Drawing title
• Date prepared
• Revision number

Possible residential site-plan scales include:

• 1 inch = 10 feet
• 1 inch = 20 feet
• 1 inch = 40 feet for larger properties

Minneapolis guidance for residential drive approaches asks for a scaled plan showing property lines, the street, sidewalk and nearby structures or assets. [8]

What if the Driveway Connects to a State Highway?

A driveway connecting to a state highway may require approval from the state transportation department rather than—or in addition to—the local city or county.

The review may consider:

• Highway speed
• Sight distance
• Traffic volume
• Distance from intersections
• Drainage
• Driveway design
• Whether another access route is available

Denver advises that a driveway connecting to a state highway may require a Colorado Department of Transportation access permit and transportation engineering plan. [15]

Charlotte also distinguishes between city-maintained and state-maintained streets when directing residential driveway inquiries. [16]

What Other Documents May Be Required?

A site plan may be only one part of the driveway application.

The permitting authority may also request:

• Driveway profile or longitudinal section
• Cross section through the apron and sidewalk
• Vehicle swept-path drawing
• Photographs of the frontage
• Civil-engineering drawings
• Drainage calculations
• Culvert design
• Retaining-wall details
• Traffic or sight-distance study
• Street-tree assessment
• Existing survey
• Contractor licence or insurance information

Portland lists a site plan, driveway profile where applicable, supporting photographs and civil drawings among the materials for a driveway-design exception. [13]

Do You Need a Survey?

Not every driveway permit requires a new boundary survey. An existing survey, house-location plan or recorded plat may provide a suitable base for the site plan.

A survey may be necessary when:

• The driveway is close to a property line
• Property corners cannot be located
• The fence does not appear to follow the boundary
• The property has an irregular shape
• An access easement is uncertain
• The driveway is shared with another property
• The permitting authority specifically asks for a survey

A drafted permit site plan is not a legal boundary survey and should not be represented as one.

Common Driveway Site Plan Mistakes

Driveway applications are often delayed because the drawing does not include enough information.

Common mistakes include:

• Property lines are missing
• The existing driveway is not shown
• The proposed driveway is not clearly labelled
• Driveway width is missing
• Curb-cut or apron width is missing
• The sidewalk is omitted
• The driveway does not align with the garage or carport
• Parking and turning areas are unclear
• Driveway slopes are not addressed
• Street trees are omitted
• Utility poles, hydrants or stormwater inlets are missing
• Sight-distance obstructions are ignored
• Drainage direction is not shown
• Easements or underground utilities are omitted
• Retaining walls and grading are not shown
• The existing curb cut to be closed is not identified
• The drawing is not to scale
• There is no north arrow
• The site plan conflicts with the garage, carport or civil drawings

What Information Is Needed to Prepare the Site Plan?

Collect as much of the following information as possible:

• Property address
• Existing driveway location
• Proposed driveway width and length
• Curb-cut or apron width
• Garage, carport or parking location
• Street and curb type
• Sidewalk location
• Nearby trees, poles, signs, hydrants and stormwater inlets
• Driveway material
• Known levels or slopes
• Drainage information
• Retaining-wall or grading information
• Photos of the street frontage
• Rough sketch with measurements
• Existing survey or plot plan
• Recorded plat if available
• Known easements and utilities
• Permit-review comments

Driveway Permit Site Plan Checklist

Does a Site Plan Guarantee Driveway-Permit Approval?

No. A clear site plan gives reviewers the information needed to understand the proposal, but approval still depends on local zoning, transportation standards, road ownership, drainage, public assets and property conditions.

The project may also require:

• Right-of-way permit
• Curb-cut or driveway-approach permit
• Zoning approval
• Sidewalk inspection permit
• Civil engineering
• Drainage or grading plan
• Retaining-wall permit
• Street-tree approval
• State highway access permit
• HOA or architectural-review approval

Need a Site Plan for a Driveway Permit?

Site Plan Pros prepares clear residential site plans for homeowners, contractors and permit applications.
