A residential site plan is the backbone of all home improvements, additions, and new constructions. It’s a key document containing plans for the property and the placement of its key features, including details on any proposed modifications. A site plan is often required to obtain building permits and contractor quotes.
In this post, we deep dive into residential site plans to uncover what they should include, why you need one, and how to get one.
A residential site plan is a detailed outline of the layout of your property, including utility hookups, site topography, and pathways. It should not be confused with a floor plan, which focuses solely on the property’s interior.
Residential site plans typically include three components; site planning, residential development, and housing layout.
Taking into account these three components will help you create a site plan that maximizes functionality, makes use of existing surroundings, and matches your chosen aesthetic.
Site plans allow you to design a property that perfectly fits your needs, but it’s often required for more than design and building purposes.
Permit offices typically want a detailed and accurate site plan to make a decision on your application.
A residential development site plan clearly shows if property plans are aligned with local zoning laws, or if the property is eligible for conditional use or special use permits. A residential site plan will also speed up the approval process so you can start development sooner.
Zoning laws and building codes can be incredibly complex. This is especially true when planning in a historic district with preservational guidelines. Residential site plans highlight any potential issues that may come up, allowing you to fix the problem before committing to the build.
Site plans can also be used for environmental impact assessments, as they demonstrate why the property won’t adversely affect the environment.
Residential site plans significantly impact the evaluation of your property, giving real estate agents a detailed view of your property to help gauge its worth.
As the site plan has been created to adhere to all applicable regulations, you can get an appraisal and sell the property safe in the knowledge that everything is up to code.
A residential site plan should be both clear and detailed, balancing aesthetic considerations with functional requirements. To ensure you have everything you need for your site plan, you should research the area you’re looking to build upon. That includes local regulations, utility placement, access roads, and weather conditions. The details contained in a site plan need to be correct, as inaccuracies can result in permits being denied, regulations being broken, and costly fixes.
Here are some key factors that should be included in any residential site plan:
Topography in the context of residential site plans offers a layout for everything within the property’s boundaries. This includes the home itself, outdoor living spaces, garages, pathways, driveways, walls, fences, trees, hedges, and any other significant features.
Clearly defined and precise property boundaries are an essential feature of a residential site map. Property boundaries show the perimeter of your land, often including structures close to the area such as other homes or buildings.
Property lines are important for obtaining permits and ensuring the property is aligned with zoning laws. They also ensure you aren’t building anything on land you do not own.
Any existing and proposed structures should be included in the residential site plan.
If you’re building an extension on your house, for example, you would draw both the existing house and the planned extension, rather than just the extension. Specific details should be given regarding changes to the property.
Easements are features with a specific purpose that are shared by the community, such as utility lines or parking lots. These are detailed on the site plan as you will need to design and build with these in mind.
Any existing landscaping features — and proposed changes — need to be included in the site plan, like trees and shrubbery, plans for runoff controls, changes to terrain, and other environmental changes.
Exterior objects are outdoor design elements that are not covered by the basic topography, such as pools, mailboxes, and fences.
In addition to their inclusion in the basic topography, your residential site plan should detail any paved areas using exact measurements. This includes pathways, driveways, and occasionally surrounding streets. You will also need to include specific dimensions for curbs and parking spaces to ensure property access is up to code.
Permit offices will look at utility lines when making their decision. The site plan should account for water sources, drainage, plumbing, electricity, sewage, and any other utilities on the property. This will help them check if everything is in order and approve the project.
Residential site plans need to be detailed and accurate. Include specific dimensions and avoid estimates to ensure the project will be approved and built correctly. Details about how changes will impact the surrounding area should also be included with exact specifications.
The two residential site plan types are 2D and 3D — with 2D providing a basic outline and 3D offering more detail.
2D residential site plans are simple, providing an outline of the property’s layout from above. 2D site plans include all buildings, structures, boundaries, landscaping, pathways, and so on. Each section is typically color-coded to differentiate between them. These plans are simple to understand, but lack depth and height, making it difficult to visualize space.
2D site plans are most commonly used for basic architectural design, zoning, construction, and documentation. They’re also used to gain planning approval and can be submitted to regulatory bodies.
3D site plans give a more realistic vision for the property, featuring depth and height in addition to the flat layout found on 2D plans. This provides a much better visualization of how the property will fit within the surrounding area.
3D residential site plans are typically used for presentations, virtual tours, and client walkthroughs.
There’s a lot you need to do to create a residential site plan, including intensive research and preparation before you even get started. Or, you can use a site plan software like 3-Minute Site Plan to do all the hard work for you — but more on that later.
Before you can put together your residential site plan, you need to gather as much information about your property as possible.
You’ll need a copy of the property survey with details of legal boundaries and dimensions of your land, and a site analysis that lays out existing conditions. You will also need to gather information on utility placement, access points, zoning laws, neighboring properties, vegetation, and drainage.
Site plan software makes it simpler to put together accurate and clear residential site plans. There are many options out there, including 3-Minute Site Plan.
When choosing site plan software, consider its ease of use, sharing capabilities, templates, customer support, and cost-effectiveness. You should also be aware that some platforms may be tailored towards specific users, such as real estate professionals, and may not be suitable for your specific needs. We compare the best software out there here.
Now, it’s time to plug all your research into the software — a tedious process often involving multiple screens and a lot of data input.
Everything you input into the site should be double-checked to ensure your resulting site plan is 100% accurate. Mistakes at this stage can result in major problems down the line, including difficulty obtaining permits, incorrect resource allocation, or problems during construction.
It’s finally time to draw up your site plan. Create precise property lines, structures, and landscape elements to produce a residential site plan everyone can understand.
At this stage, you may want to experiment with different configurations. This can be done within the confines of the existing structure dimensions or by scaling up or down.
Finally, a simple step! Send your residential site plan to the printer and you’re all done. Now you can share your plan with any relevant parties and get your project underway.
