A conditional use permit (CUP) is one of the more confusing documents in the US permitting process. This guide explains what it is, when you need one, and what site plan drawings a CUP application requires.

What Is a Conditional Use Permit?
A conditional use permit (also called a special use permit or special exception in some jurisdictions) allows a property to be used for a purpose that isn’t permitted by right in its zoning district — but may be permitted under certain conditions.
Common examples:
- A church in a residential zone
- A daycare in a commercial zone not zoned for childcare
- A home-based business that generates customer traffic
- A drive-through restaurant in a zone that normally prohibits them
- A storage facility in a light industrial zone
- A cell tower on a property not zoned for towers
The “conditions” are specific requirements attached to the permit — operating hours, traffic management plans, buffers, fencing, landscaping, etc.
CUP vs. Variance vs. Rezoning
These three are commonly confused:
Conditional Use Permit (CUP): Allows a specific use that’s already listed in the zoning code as conditionally permitted — subject to review and conditions.
Variance: Allows deviation from a specific development standard (like setback distance or height limit) while keeping the same use classification.
Rezoning: Changes the zoning classification of the property entirely — a legislative act requiring city council or board approval.
A CUP is typically faster and more limited in scope than a rezoning.
What Site Plan Does a CUP Application Require?
CUP applications typically require a more detailed site plan than a standard building permit. You should expect to include:
For all CUP applications:
- Complete property boundaries with dimensions
- All existing structures with dimensions
- Proposed use/structure clearly labeled
- Setbacks from all property lines
- Parking layout with space count and ADA compliance
- Vehicular access and circulation
- Buffers and screening (required for many conditional uses)
- Scale, north arrow, complete title block
Commonly also required:
- Landscape buffer plan
- Lighting plan notation
- Signage setback notation
- Traffic circulation diagram
- Drainage notes
- PE stamp in many jurisdictions for commercial CUPs
The exact requirements vary significantly by jurisdiction. Always request the CUP application checklist from your planning department.
