Home improvements, additions, and new construction all begin with one thing — a plot plan. It provides an on-paper plan for the property, detailing the proposed modifications. They are often required to obtain building permits and contractor quotes.
Below, we explore exactly what a plot plan is, what key components it includes, why and when you need one, as well as how to get one for your property.Â

What is a plot plan?
The terms site plans and plot plans are interchangeable. They refer to a map or diagram of a plot of land which details all existing (and proposed) structures, features, and topography. These renderings are drawn to scale using computer-aided drafting (CAD) and often include every detail down to trees, poles, and power lines.
Plot plans aren’t the same as floor plan — they’re a lot more technical. Floor plans are a different set of CAD plans detailing interior building layouts. By comparison, plot plans describe exterior features and layouts.

What does a plot plan include?
What are the essential features that all plot plans should include? If so many different professional service providers rely on these plans, what are they looking for?
Designer name, date, and property address
The first information that should be easy to locate is the designer's name, who drafted the plans and the date they were created, and the property address for the plot plan. Property changes occur over time, so it is essential to quickly identify the current draft of the plot plan.
Scale
One of the primary purposes of a plot plan is to depict an accurate representation of the property and proposed changes. Therefore it is important that all measurements are precise and drawn to scale. In addition, plan labels should include square footage measurements for structures where appropriate.
Property lines and labels
The plans should begin with a clear definition of property lines and then work inward to detail the location and size of all structures and features. All items on the plan should include clear labels like 'house' and 'garage.'
Setbacks
In addition to property lines, site plans should also include setbacks defined by local ordinances or HOA regulations. This defines how far back from the property line a structure can sit. For road frontage, these setbacks are typically between 30 and 40 feet. For other property lines, the setback may be between five and ten feet.
Structure
Once all of the essential structures are in place and relative distances are noted, it is time to add slope and elevation. This element will help builders and designers make sure that they do not interfere with drainage patterns. Trees, shrubbery, and bushes are included if they are relative to the proposed changes.Â
Typography
The typography can include many different things depending on the composition of the property. The most common typography items include the house, outbuildings, pools, decks, patios, and driveways.Â
Easements
Additional features include all utilities like gas lines and water mains which should be noted on the plans. Easements for external access to the property, as well as driveways, should also be drafted.
Legend
And finally, you will need to provide directions for interpreting your plans. This includes a legend that depicts symbols used in the plot and defines the orientation of the drawings so that there is no confusion.
Plot plan examples
My Site Plan offers three levels of plot plans drawn by expert designers to fit many different needs. Our plot plans are accepted by building departments nationwide and make a convenient alternative when an architect is not required. You can see examples of each of these plot plan types below.
Basic plot plan example
A basic plot plan will give you the basics of your property. GIS and Satellite imagery is usually used to create the draft. This plot plan will include existing primary building roofline, lot lines, and a north arrow. While generally insufficient for building permits, this plan is great for planning.
Medium plot plan example
Residential site plans are perfect for building or demolition permit applications and project planning. They are widely accepted by building departments and HOAs for residential permitting purposes.
Detailed plot plan example
Residential site plans are perfect for anyone who wants to avoid a second trip to the permitting office. Get the highest level of detail possible with an accurate construction site plan.
Why do I need a plot plan?
Local and county governments commonly request these residential diagrams for historical records, tax valuation, and ordinance enforcement. Thus, they serve many different functions depending on who is requesting these documents, including:
Navigation
Development
Communication
Function
Aesthetics
In addition to local officials, designers and contractors regularly use these plans to draft designs and quote pricing or bid work. These plans help each party understand how the proposed changes will impact the function or aesthetic of the property. They also communicate a clear picture of the proposed changes to all parties.
If you live in a homeowners association, plot plans will surely be required for all significant changes and may even be necessary for seemingly minor changes. HOA's tend to be much more strict than local governments when making changes to your property.Â
When do I need a plot plan?
Homeowners perform all kinds of work to their homes that might require the use of a plot plan. In general, any job that requires a building permit will also need a plot plan. This includes project like:
Fencing installation (or significant changes to fencing height)
Structural changes like adding a deck or porch
Utility work like plumbing or electrical
HVAC work like changing duct systems or adding a fireplace
Installing new windows, doors, or skylights
How do I get a plot plan for my property?
Some homeowners with a little bit of CAD experience can draft up simple plans. However, it is a good idea to rely on the expertise of an experienced designer when making significant structural changes to your home.
My Site Plan can provide you with detailed site plot plans for your next home improvement project. Our team of expert designers has more than twenty years of experience to provide you with professionally created plans.Â
Plot plan FAQs
How to read a plot plan
To read a plot plan effectively, start by examining the title block, which contains key information such as the project name, address, scale, date, and designer's name. The north arrow indicates the plan's orientation, which is crucial for understanding how the property aligns with its surroundings. The scale provides a ratio for translating the plan's measurements to actual distances on the ground.
Identify property lines, which outline the plot's boundaries and often include dimensions. Look for setback lines, which show the required distance between structures and property lines. Building footprints, shown as solid outlines, represent existing or planned structures and are labeled with dimensions. Contour lines indicate elevation changes, with closely spaced lines showing steep areas. Utility lines, such as those for water or electricity, and easements, areas designated for specific uses like utility access, are also marked on the plan.
Finally, review the legend and notes for explanations of symbols and additional information about the plot.Â
Plot plan vs floor plan - what are the differences?
A plot plan maps the exterior features of a property, including landscaping, structures, and utilities, and is used for planning exterior modifications and obtaining permits. A floor plan, however, focuses on the interior layout of a building, detailing room sizes, door and window locations, and the arrangement of fixed installations like cabinets and appliances.
How often should a plot plan be updated?
A plot plan should be updated any time significant changes are made to the property, such as additions, demolitions, or significant landscaping changes. Updating is crucial to maintain accurate records for future modifications, permits, or sales.
Can a homeowner draft their own plot plan?
Yes, a homeowner with CAD experience can draft their own plot plan for smaller projects. However, for significant changes or when precision is crucial, it's recommended to hire an experienced designer to ensure accuracy and compliance with local regulations.
What are common setbacks included in plot plans?
Setbacks vary by local ordinances but typically range from 30 to 40 feet for road frontages and 5 to 10 feet from other property lines. These setbacks dictate how far a structure must be from the property line, impacting where structures can be placed.
What should be considered when choosing a designer for a plot plan?
When choosing a designer for a plot plan, consider their familiarity with local building codes and ordinances, experience in drafting detailed CAD plans, and their ability to clearly communicate the proposed changes. It’s also beneficial to review their past work to ensure it meets your needs.
