What is a Site Plan? Zoning Definition
A scaled drawing that shows the layout of a property, including building placement, setbacks, parking, landscaping, and other site features, submitted as part of a development or building permit application.
A site plan is a detailed, to-scale diagram of a property that shows where buildings, driveways, parking areas, utilities, landscaping, and other improvements are located or proposed. Most cities and counties require a site plan whenever you apply for a building permit, zoning approval, or subdivision review. The plan helps officials verify that your project complies with setback requirements, lot coverage limits, height restrictions, and other zoning regulations.
Site plans typically include property boundaries, dimensions, the location and footprint of all existing and proposed structures, driveways and parking spaces, stormwater drainage features, and landscaping areas. They also show easements, rights-of-way, and utility connections. For larger projects, the city may require a more detailed version prepared by a licensed surveyor, engineer, or architect.
For example, if you want to build a detached garage in your backyard, the planning department will likely ask for a site plan showing the garage's location relative to property lines, the main house, and any setback requirements. If the garage encroaches into a required setback, your permit could be denied or you may need to apply for a variance.
Many jurisdictions distinguish between a basic site plan (often acceptable for simple residential projects) and a full site development plan required for commercial or multi-family developments. Check with your local planning department to find out exactly what level of detail is needed for your project.
