Phoenix Carport Site Plan for Permit: Property Lines, Parking and Driveway Access
A carport can provide welcome shade for vehicles in Phoenix. Before choosing its location, check how the roof, support posts and parking area will fit within your property.
A Phoenix carport site plan shows the proposed structure alongside property boundaries, existing buildings and driveway access. It helps explain the arrangement clearly and identify placement problems before construction begins.
Does a Carport Need a Permit in Phoenix?
The City of Phoenix lists garage and carport construction or conversion among residential projects requiring construction permits.
[1]
Before ordering a carport kit or installing foundations, describe your proposal to Planning & Development. Include its dimensions, height, materials, attachment to the house and any electrical work.
Do not assume that an open-sided, prefabricated or metal structure is automatically exempt. Ask the city which permit and supporting documents apply to the actual design.
Start With Jurisdiction, Zoning and Property Lines
Confirm that the parcel is within the City of Phoenix. A property elsewhere in the metropolitan area may fall under another municipality or unincorporated Maricopa County.
Next, establish the property’s zoning and reliable boundary information. Phoenix’s single-family plot-plan guide recommends verifying zoning, setbacks and allowable lot coverage before preparing a drawing. It identifies recorded subdivision plats as a source of property dimensions and easements.
[2]
An existing fence or block wall should not be treated as proof of the legal boundary. Use available survey and recorded property documents. If the boundary cannot be established reliably, consult a licensed surveyor.
Read our site plan versus survey guide for the difference between drafting a proposed layout and surveying legal boundaries.
Check Carport Setbacks Before Finalizing Placement
Identify whether the carport will attach to the house or stand independently. Ask the city which zoning provisions apply to that arrangement.
Section 706.B of the Phoenix Zoning Ordinance addresses non-ADU accessory structures on single-family residential lots. Its provisions include a minimum three-foot side or rear setback, an exception beside a fully dedicated alley where vehicle maneuvering does not require a setback, and restrictions on front-yard placement.
[3]
Confirm the structure’s classification before applying these provisions. Do not assume the same placement rules apply to every attached or detached carport.
Show both the roof outline and support-post locations. Ask how the city measures setbacks for your design and whether roof projections, building separation or special property conditions affect the proposal.
Show Usable Parking Space
The roof size alone does not show whether vehicles can park comfortably. Posts, walls and other obstructions can reduce the usable area beneath it.
Phoenix Zoning Ordinance Section 702 requires parking plans to identify parking spaces, driveways and maneuvering areas. It also addresses access from a public street or alley and sufficient vehicle maneuvering.
[4]
When preparing the layout:
- Dimension the parking area: Show the clear usable space, not just the roof footprint.
- Locate every post: Check whether supports interfere with parking or turning.
- Preserve access: Show how vehicles reach each space.
- Check door clearance: Consider getting in, getting out and unloading.
- Show existing parking: Explain which spaces remain after construction.
Ask the city to confirm the required parking count and applicable dimensions for your property. If vehicles will park one behind another, identify the tandem arrangement clearly rather than leaving it to the reviewer to infer.
Connect the Carport to the Driveway
A useful site plan shows the complete vehicle route from the street or alley to the parking area.
Include the existing driveway, any proposed changes and relevant gates or obstructions. Compare the post locations with the approach vehicles will take.
For example, a carport roof may fit beside the house while a support post narrows the driveway entrance. Moving the post or changing the carport location may improve access, but any structural change needs coordination with the designer or supplier.
Driveway work can have separate requirements
Phoenix’s Driveway Policy for Single Family Development explains that access to public streets is controlled by City Code Section 31-44. Permit requirements depend on the street configuration and the work within the right-of-way.
[5]
If the project changes the driveway entrance, curb, sidewalk or connection to the street, describe that work separately when asking about approvals. Do not assume the carport permit covers every access improvement.
What Should a Phoenix Carport Site Plan Show?
Phoenix’s plot-plan example provides a useful checklist for presenting residential site information.
[2]
| Detail | What to include |
|---|---|
| Identification | Address, parcel number, zoning, north arrow and scale. |
| Boundaries | Property dimensions, adjacent streets, alleys and known easements. |
| Structures | Existing buildings and the proposed carport, with dimensions. |
| Setbacks | Required and provided placement distances. |
| Parking and access | Parking dimensions, driveway layout and relevant gates. |
| Coverage | Allowed and proposed lot coverage totals. |
Clearly distinguish existing features from proposed work. Label any structure or paving that will be removed so the final arrangement is easy to understand.
Review Easements and Lot Coverage
Check known utility, drainage and access easements before placing posts, foundations or roof projections within them. Review the recorded terms and resolve any uncertainty with the relevant easement holder.
The city’s plot-plan guide also calls for a coverage summary that accounts for the primary structure, attached shade and detached accessory structures.
[2]
Confirm how the proposed carport is counted. Open sides do not provide a reason to leave the structure out of the calculation without checking the applicable rules.
A Site Plan Does Not Replace Construction Details
The site plan explains where the carport goes and how it relates to the property. Construction drawings explain how it will be supported and built.
Ask which supporting documents are required for:
- Foundations and anchoring.
- Posts, beams and roof framing.
- Connections to the house, if proposed.
- Manufacturer specifications or engineered components.
- Lighting, wiring or other electrical work.
Coordinate the site plan with those documents. The carport’s dimensions and location should agree throughout the submission.
Prepare for Submission
- Confirm jurisdiction, zoning and boundary information.
- Describe the carport and driveway work to the city.
- Check setbacks, parking, easements and coverage.
- Prepare a scaled site plan with clear dimensions.
- Gather the required construction documents.
- Follow the city’s current application instructions.
Phoenix provides residential plan review, permitting and inspections through the SHAPE PHX portal.

Frequently Asked Questions
Can I build a carport over my existing driveway?
Possibly, but existing paving does not establish that a roofed structure is allowed there. Check placement, parking clearance, access and construction requirements.
Should the support posts appear on the drawing?
Yes. Their locations help explain usable parking space and whether vehicles can approach without obstruction.
Can I use the featured image as my permit drawing?
No. It illustrates planning concepts. Your submission needs property-specific information and the detail required for your project.
Does ordering a site plan guarantee approval?
No. Approval depends on the applicable requirements, proposed design, supporting documents and city review.
