ToggleKey Takeaways:
- Certified site plans ensure compliance and accuracy with legal and regulatory requirements.
- Non-certified site plans offer a cost-effective alternative ideal when formal certification isn’t mandatory.
- Certified site plans are essential when a professional stamp is required for compliance, but for projects where certification isn’t mandatory, non-certified plans can offer similar details at a lower cost.
Do You Need a Certified or Non-Certified Site Plan?

Whether you need a certified or non-certified site plan depends on the specific purpose of the plan and the local authorities’ requirements.
In general, certified site plans are considered necessary for legal and compliance-related purposes, while non-certified plans are considered flexible and affordable for less formal uses.
However, this isn’t the universal rule.
What is a Non-Certified Site Plan?

A non-certified site plan is a detailed drawing or map of a property that shows features like buildings, boundaries, driveways, and utilities, but it hasn’t been officially reviewed or stamped by a licensed professional (like a surveyor or engineer).
It can be created by a homeowner, an unlicensed designer, or an online drawing service like GetASitePlan.
It’s typically used for preliminary planning or informational purposes but may not meet the strict requirements needed for official approval, permits, or legal filings.
However, some authorities acknowledge non-certified site plans as relevant and acceptable for specific purposes.
When Non-Certified Options May Be Sufficient
Non-certified site plans may be sufficient for projects where certification is unnecessary.
These projects are:
- Landscaping designs
- Minor home improvements
- Informal presentations or proposals
However, it’s essential to confirm with your local municipality or governing body before proceeding.
Many jurisdictions clearly outline when a certified plan is mandatory and when a non-certified plan is acceptable.
If non-certified plans meet their criteria, opting for them can save you significant time and money while ensuring your project complies with the necessary regulations.
How Much Does a Non-Certified Site Plan Cost?

A non-certified site plan can cost between $89 and $300, depending on various factors.
The most common factors that affect the cost are:
- Property Size: Larger properties typically require more detail, increasing the cost.
- Detail Requirements: Plans with additional details, such as grading, utility layouts, or landscaping, cost more.
- Turnaround Time: Expedited services often come with an added fee.
- Service Provider: Costs vary between professional drafters, architects, and online redraw services.
Regardless of the factor, non-certified site plans are generally much more affordable than certified plans, as certified plans have a specific, expensive requirement.
What is a Certified Site Plan?

A certified site plan is a detailed and officially verified document that illustrates the layout and features of a property.
Since property layout requires official certification, certified site plans are prepared and certified by licensed professionals, such as surveyors, architects, or engineers, to ensure accuracy.
For example, engineers play a critical role by certifying site plans, verifying measurements, and ensuring layouts meet both technical and legal requirements.
These professionals, like architects, design the layout, ensuring it adheres to regulatory standards and supports project planning and implementation.
Therefore, certified site plans, both commercial and residential, are carefully engineered to meet standardized requirements and ensure scalability for future property development.
They are required for legal documentation and permits and represent the plan you will need to obtain for specific projects.
Certified site plans include essential information such as:
- Property boundaries
- Building locations
- Utility lines
- Landscaping
- Any proposed changes
By providing this information, certified site plans help verify property details and ensure they comply with legal requirements.
Authorities approve documentation as part of the permitting process to ensure all aspects of the project meet legal and safety requirements.
How Much Does a Certified Site Plan Cost?

On average, certified site plans typically cost between $500 and $3,000 or more, depending on project complexity.
They are a much more expensive option because they require a licensed surveyor or engineer’s involvement and certification.
When Do You Need a Certified Site Plan?
A certified site plan may be needed for various purposes, usually encompassing building permits and ensuring compliance.
Yet, the list of purposes can go beyond this, covering the following:
- Applying for zoning permits
- Submitting plans for property development or renovation
- Meeting lender or insurance requirements
- Resolving boundary disputes or legal matters
- Supporting permit approval through documentation that adheres to regulatory standards
- Inspection verifies compliance, ensuring compliance with local ordinances and codes
For these reasons, it’s important to find relevant options for obtaining these plans.
Where to Obtain a Certified Site Plan?
You can obtain a certified site plan from licensed professionals who have their stamp to put on the document.
These sources include:
- Licensed land surveyor (who also measures property dimensions)
- Professional engineers or architects
- Specialized firms offering surveying and planning services
- Local government offices that may provide access to property records and maps
The experts certify the accuracy of the plan, measure property dimensions, inspect key site features, and implement verification processes to ensure compliance with all applicable regulations.
Documentation supports permit approval by ensuring that all elements of the plan meet regulatory standards and are consistent with local requirements. This verification process assures authorities, helping streamline approvals.
On the other hand, obtaining a non-certified site plan is a simpler and quicker process.
How to Obtain Non-Certified Site Plans?

To obtain non-certified site plans, you can choose between creating them yourself, hiring local designers, or using online drawing services.
Each option offers a unique balance of cost, speed, and convenience.
Here’s a brief description of every option (if you need a more thorough explanation, you can find it in our “How to Obtain a Site Plan of my Property” article).
DIY – Create a Site Plan on Your Own
Creating a site plan yourself is the cheapest option if you have a sense of drawing, spare time, and clear instructions on how to draw a site plan.
You can choose between physical tools like graph paper and a pen, or you can use software specialized for drawing site plans.
But before you submit a DIY site plan, it is important to review the specific requirements set by local authorities to ensure your plan will be approved.
For instance, the City of Midland’s Site Plan Review Checklist specifies that site plans must adhere to designated scales based on property size [1]:
- For properties less than 1 acre: 1 inch = 20 feet
- For properties larger than 1 acre but less than 3 acres: 1 inch = 30 feet
- For properties larger than 3 acres: 1 inch = 50 feet
Standardization across site plans ensures they are scalable for future development and meet all approved regulatory requirements.
Local Designers
Local designers or drafters can produce accurate, non-certified plans tailored to your needs at a lower cost than certified professionals.
Yet, the price may vary depending on the designer and country, and in some cases, it can be only slightly cheaper.
Online Services – GetASitePlan
Online services like GetASitePlan provide quick and affordable non-certified site plans.
GetASitePlan is especially useful for straightforward projects, permits, or when you need a plan in digital format.
You can pick different packages depending on the level of detail you want to be shown on your site plan and get them in 24 hours for an affordable price.
What Is a Certified Plot Plan?

A certified plot plan is a specific type of certified plan focused on property boundaries and structures.
It includes precise measurements and is often used for:
- Legal documentation
- Property transactions
- Ensuring the plan complies with zoning or setback regulations
Key differences between certified site plans and plot plans are in their scope and use case.
Regarding the scope, site plans provide accurate property boundaries and include the detailed layout of landscaping, infrastructure, and buildings, while plot plans focus primarily on property boundaries and structures.
Speaking about use cases, site plans are more comprehensive for development projects, while plot plans are typically used for legal or real estate purposes.
Picking the Most Suitable Site Plan for Your Build

Choosing the right site plan ultimately depends on your project’s scope, budget, and requirements.
Certified site plans meet regulatory standards, ensuring compliance with legal documentation, zoning regulations, and permits.
However, non-certified site plans can serve the same purpose, depending on local authorities and their requirements.
The key is to evaluate your project’s specific needs and consult with the appropriate authorities to ensure you have the right documentation.
