You don’t need expensive custom plans to get started.
Many California cities offer pre-approved ADU designs — plans that are already reviewed and code-compliant.

We help you take full advantage of preapproved plans and turn one of those plans into a ready-to-build project on your property.

A site plan is a scaled drawing that represents the layout of a plot of land, showing property features, boundaries, existing structures, and proposed additions. It plays a fundamental role in any construction project—from a new home to a commercial property development—helping ensure compliance with local regulations and building codes.
A good site plan should clearly display:
– Property lines and boundaries
– Existing structures and new structures
– Lot dimensions and size of the tree
– North arrow for orientation
– Utility lines and main lines
– Landscape features and landscape elements
– Parking areas, location of driveways, and green spaces
– Septic tank or other critical information specific to the plot
A site plan outlines the layout of the property, showing the house’s footprint and other key features. A floor plan shows the interior spaces of a home.
A licensed surveyor produces a survey using official monuments to confirm property boundaries. A non-licensed professional can create a site plan that reflects the existing or proposed conditions.
Yes, a surveyor can create a site plan showing existing structures, often referred to as an ‘as-built’ site plan. Surveyors do not show future buildings. To make a proposed site plan, you will need to engage the services of a drafter, architectural designer, or architect.
For commercial properties or when required by local governments, yes. Minor residential projects often accept non-certified site plans.
