When applying for permits in California — whether for an ADU, pool, garage, driveway, deck, or commercial project — one of the first things your local city or county will ask for is a permit-ready site plan. Without it, your permit application can be delayed, rejected, or sent back for costly revisions.
In this article, we’ll explain why site plans for permit approval are so important, what they must include, and how homeowners, contractors, and developers across all 58 California counties can get affordable site plans online delivered in just 24 hours.
What Is a Site Plan?
A site plan (also called a plot plan) is a scaled drawing that shows the layout of your property. It includes details such as:
- Property lines and boundaries
- Setbacks (the required distance between structures and property lines)
- Building footprints (house, ADU, garage, shed, etc.)
- Driveways, sidewalks, and parking
- Pools, decks, and landscaping features
- Easements and utility placements
