Most homeowners and many contractors don’t realize that commercial projects often require two separate approval processes — and two different levels of site plan documentation.
The first is entitlement review — approval from the planning department or planning commission confirming the proposed use and development is consistent with zoning and land use policy. The second is building permit plan check — technical review confirming the construction meets code.
I’m Engineer Wasim of Site Plans Online USA. This guide explains what planning commission review involves, what site plan documentation is required, and how it differs from the site plan you submit for a building permit.
What Is Planning Commission Review?
A planning commission is a local government body — typically appointed rather than elected — responsible for evaluating land use applications. Planning commission review applies when a project requires discretionary approval, meaning it doesn’t meet all zoning requirements by right and needs a public decision.
Projects that typically require planning commission review:
- Conditional Use Permits (CUPs) — see: Conditional Use Permit Guide
- Variances — requests to deviate from standard zoning requirements
- Site plan review — required in many cities for commercial projects above a certain size
- Planned unit developments (PUDs)
- Subdivision and parcel map approvals — see: Subdivision Site Plans
- Environmental review under CEQA (California) or NEPA (federal)
- Design review in historic districts or design overlay zones
Projects that typically skip planning commission (ministerial approval):
- Most single-family residential permits
- ADU projects in California and similar states with ministerial ADU approval
- Commercial projects that comply with all zoning standards by right
Planning Commission Site Plan vs. Building Permit Site Plan
These are different documents serving different purposes.
Planning commission site plan (entitlement drawings): Used to evaluate policy, use compatibility, and design. The audience is planning staff, planning commissioners, and potentially the public.
Required elements typically include:
- Accurate, dimensioned site plan to scale
- Existing and proposed land uses labeled
- Building footprints with dimensions and heights
- Complete parking layout with count
- Pedestrian and vehicular circulation shown
- Landscaping plan or landscape buffer locations
- Outdoor use areas (patios, drive-throughs, loading)
- Lighting plan or notation
- Signage setbacks
- Relationship to surrounding properties shown
- Elevation drawings showing building facades
- Sometimes: perspective renderings or 3D images for larger projects
Building permit site plan: Used to verify code compliance. More technical, less context. Required elements are more prescriptive and code-specific. See: Commercial Site Plans for Permits
The Planning Commission Process — How It Works
Understanding the timeline helps you prepare site plan documentation at the right level:
Step 1 — Pre-Application Meeting: Many cities offer (or require) a pre-application conference before submitting entitlement applications. The planner reviews your concept, identifies issues, and clarifies requirements. At this stage, a concept-level site plan is sufficient — not fully detailed, but scaled and showing basic layout.
Step 2 — Application Submission:l Full application, including entitlement-level site plan, project description, environmental forms, and fees. Most cities require multiple physical copies for planning review, unlike building permits, which are now largely digital.
Step 3 — Staff Report Planning staff prepares a report analyzing the project against applicable plans and codes. Staff recommends approval, approval with conditions, or denial.
Step 4 — Public Hearing The project is heard at a noticed public meeting. Neighbors and interested parties can comment. The commission votes. Learn more about how these boards evaluate layouts during the Site Plan Review Process.
Step 5 — Conditions of Approval.l If approved, conditions specify what must be done or provided before or during construction — parking lot improvements, landscaping, traffic studies, etc.
Step 6 — Building Permit Application. After entitlement, you submit for a building permit. The building permit site plan is now a separate, more technical document that must comply with the conditions of entitlement approval, following strict Site Plan Drawing Requirements.
PE Stamp for Planning Commission Site Plans
Planning commission site plans are not always required to be PE-stamped. They are evaluated for land use compatibility, not structural compliance. However, for complex commercial projects, grading plans submitted alongside the entitlement application typically require a PE stamp.
The building permit drawings — which follow entitlement — do require a PE stamp for commercial construction. See: PE Stamp Services
