Shed, ADU & Accessory Structure Site Plans
Planning to add a storage shed, a modern ADU, or a backyard workshop? Most municipalities require a detailed site plan before you can even break ground. At Prime Site Plan, we bridge the gap between your vision and city approval. Our team specializes in creating high-precision AutoCAD site plans that clearly identify setbacks, existing structures, and proposed footprints.
Zoning Compliance & Topographic Precision
By utilizing advanced GIS data and high-resolution satellite imagery, we deliver professional-grade layouts remotely — eliminating the need for expensive site visits or land surveys. This allows us to provide faster turnarounds while maintaining 99% accuracy for residential permits.
