Zoning & Planning for Commercial Development: Where Should You Start?
Whether you are developing a new commercial building, opening a new tenant space, or renovating an existing commercial property, one of the first questions should be: What zoning and planning approvals will be required before the project can move forward?
This question sounds straightforward, but the answer can be surprisingly complicated.
A project may require only an administrative zoning review. Another project may require site plan approval, a zoning variance, architectural or design review, historic approval—or a combination of several of these. The requirements can also change depending on the Authority Having Jurisdiction (AHJ), the property's zoning district, applicable overlays, the proposed use, and the scope of the development.
For commercial projects, understanding the approval path early can prevent costly redesigns, delays, and surprises later in the permitting process.
So, where should you start?
Start With the Property—not the Building Plans
Before getting too far into architectural design, begin by understanding the property and the regulations that control it.
The first step is typically to identify the property's base zoning district. The base zoning establishes the fundamental rules for the property, including permitted uses, dimensional requirements, setbacks, building height, lot coverage, parking requirements, signage, and other development standards.
But the base zoning district is only the starting point.
A property may also be subject to one or more overlays or special zoning regulations that impose additional requirements. These can include historic districts, design districts, waterfront or environmental overlays, redevelopment areas, transit-oriented districts, or other special planning areas.
This is why simply confirming that a proposed use is permitted in the base zoning district does not necessarily mean the project is ready to proceed.
1. Understand the Base Zoning
The first question is: Is the proposed use permitted at this property?
If the answer is yes, the next questions involve the physical characteristics of the proposed development.
For example:
Is the proposed building size permitted?
Does the project comply with required setbacks?
Is the building height permitted?
Does the lot meet minimum dimensional requirements?
Is the proposed parking sufficient?
Are loading spaces required?
Are there landscaping or screening requirements?
Are signs permitted as proposed?
Are there limitations on building coverage or impervious surface?
Does the proposed use trigger additional zoning requirements?
For a tenant fit-out, the analysis may also involve determining whether the proposed business use is permitted and whether the change in use creates additional requirements for parking, occupancy, site improvements, or other approvals.
A project that appears to be an interior renovation can therefore have zoning implications if the proposed tenant represents a change in use or increases the intensity of the property's use.
2. Check for Overlays and Special Regulations
After establishing the base zoning, determine whether the property is subject to any overlay districts or special regulations.
Overlays can significantly change the approval process.
For example, a property located within a historic district may require review by a Historic Preservation Commission or similar body. A property within a special design district may be subject to additional architectural standards. Other overlays may address environmental conditions, redevelopment, transportation, flood hazards, or other site-specific concerns.
These requirements can affect everything from the building's location and massing to exterior materials, landscaping, parking, lighting, signage, and access.
The important point is that two properties with the same base zoning designation may not have the same approval requirements.
3. Determine Whether Historic or Design Review Applies
Historic and architectural review can introduce another layer into the development process.
If a property is located within a designated historic district—or if the existing building itself is historically designated—exterior alterations may require approval from a historic preservation commission or similar authority.
Likewise, some municipalities have architectural or design review boards that evaluate the appearance and design of proposed development.
The review may consider items such as:
Building massing and scale
Exterior materials
Roof design
Windows and doors
Storefront design
Colors and finishes
Signage
Lighting
Landscaping
Relationship to neighboring properties
Design review requirements vary widely between jurisdictions. The American Planning Association notes that design-review triggers can depend on factors such as project size, location, or land-use type.
For that reason, architectural design should be coordinated with the applicable review requirements rather than developed independently and submitted for review at the end.
4. Determine Whether Site Plan Approval Is Required
The next major question is: Does the project require site plan approval?
Site plan review allows the reviewing authority to evaluate the proposed development as it relates to the specific property.
Unlike zoning regulations, which establish general standards for properties within a zoning district, site plan review focuses on how the proposed development actually fits on the site. The American Planning Association describes site plan review as a process that can address site layout, circulation, materials, and other development considerations beyond the basic zoning regulations. (American Planning Association)
Depending on the jurisdiction and project, site plan review may examine:
Building location
Parking
Vehicular circulation
Pedestrian access
Driveways and curb cuts
Landscaping
Lighting
Stormwater and drainage
Loading
Screening and buffering
Signage
Utilities
Site grading
Building design
For a new commercial development, site plan approval is frequently a significant component of the entitlement process.
But site plan requirements can also apply to existing commercial properties and tenant improvements.
Some jurisdictions require review for changes in use, changes to parking, increases in occupancy, additions, or other modifications to an existing commercial property. Others may provide exemptions or administrative waivers for certain types of projects. For example, municipal regulations may distinguish between major site plans, minor site plans, and projects eligible for administrative review or waiver. (Ecode360)
This is why the scope of work needs to be evaluated against the specific jurisdiction's regulations.
5. Determine Whether a Zoning Variance Is Required
If the proposed development does not comply with one or more zoning requirements, a variance or other form of zoning relief may be necessary.
There are different types of zoning relief, and the terminology and procedures vary by jurisdiction.
A project might require relief because of:
A prohibited or conditional use
Building setbacks
Height
Lot coverage
Parking
Lot dimensions
Signage
Other dimensional requirements
Importantly, a variance is not simply another permit.
It can change the approval process, introduce additional documentation and justification, require public notice and a hearing, and potentially add significant time to the project schedule.
And this is where zoning and site plan approval can overlap.
6. Sometimes You Need Zoning Approval and Site Plan Approval
One of the most important concepts for commercial development is that zoning approval and site plan approval are not always separate, sequential processes.
Depending on the jurisdiction, a project may require:
Zoning approval only
The project complies with applicable requirements and does not trigger formal site plan review.
Site plan approval only
The proposed use and development comply with zoning, but the jurisdiction requires the Planning Board or another reviewing body to approve the site development.
Zoning variance + site plan approval
The project requires relief from one or more zoning requirements and also requires review of the proposed site development.
In some jurisdictions, the Planning Board handles site plan applications while the Zoning Board of Adjustment handles certain types of variances. In other situations, the board handling the variance may also have authority to review the site plan.
For example, municipal regulations can specifically provide that a site plan requiring a use variance is reviewed by the Zoning Board of Adjustment rather than the Planning Board.
The key takeaway is simple: You cannot determine the approval path by looking at the project type alone.
You have to look at the jurisdiction's zoning ordinance and development procedures.
7. Identify All Authorities Having Jurisdiction
Another potential complication is that there may be multiple Authorities Having Jurisdiction (AHJs) involved in the project.
The municipality may be only one part of the approval process.
Depending on the property and scope of work, additional agencies or authorities could have jurisdiction over specific aspects of the development.
For example, a project could potentially involve:
Municipal Zoning Officer
Planning Board
Zoning Board of Adjustment
Historic Preservation Commission
Architectural or Design Review Board
Local/State DOT
Engineering Department
County agencies
State agencies
Environmental agencies
Transportation authorities
Utility authorities
Each authority may have its own application requirements, review standards, meeting schedules, fees, and procedures.
This makes it important to identify the complete approval matrix early rather than treating each approval as an isolated permit.
So, Where Should You Start?
The best place to start is with a zoning and planning feasibility review.
Before investing significant time and money into detailed architectural drawings, determine:
What is the property's base zoning district?
Is the proposed use permitted?
What dimensional requirements apply?
Are there zoning overlays or special districts?
Is the property historically designated or located in a historic district?
Does architectural or design review apply?
Is site plan approval required?
Is a zoning variance or other relief required?
Which board or authority has jurisdiction?
Are multiple AHJs involved?
What applications, documents, studies, and drawings will be required?
What is the likely sequence of approvals?
Answering these questions early can help establish a realistic development and permitting strategy.
The Bottom Line
There is no universal approval path for commercial development.
A new commercial building, a restaurant conversion, a retail tenant fit-out, and an office renovation may all have very different zoning and planning requirements—even within the same municipality.
The applicable AHJ, zoning ordinance, overlays, development regulations, and local procedures ultimately determine what approvals are required.
Sometimes the project can proceed administratively.
Sometimes it requires site plan approval.
Sometimes it requires a zoning variance.
And sometimes it requires both zoning relief and site plan approval, potentially along with historic, architectural, environmental, or other agency approvals.
The earlier these requirements are identified, the easier it is to design the project around them.
Start with the property. Understand the zoning. Identify the overlays. Determine the required approvals. Then develop the project around the approval path—not the other way around.
For commercial developers, owners, architects, contractors, and tenants, that early due diligence can be one of the most valuable steps in keeping a project moving toward approval.
