Know the Scope Before You Order

What Your Site Plan May Include

Every project is reviewed individually. We confirm the drawing scope, required source documents and any separate professional services before drafting begins.

Common Site Plan Components

  • Property boundaries based on available source information
  • Existing and proposed buildings or structures
  • Setbacks, dimensions and project notes
  • Driveways, access routes and paved areas
  • Parking information and site features
  • Lot coverage or area calculations when scoped
  • Easements and utilities when reliable data is available
  • North arrow, drawing scale and PDF delivery

May Require Separate Professional Services

  • Boundary, topographic or construction surveying
  • Structural or civil engineering calculations
  • Architectural floor plans and building sections
  • Geotechnical, soils or environmental reports
  • Energy calculations or specialty code reports
  • Field verification by a licensed local professional
  • Professional stamps or signatures when legally required
  • Permit-expediting or municipal application fees

Important: A drafting site plan is not automatically a legal boundary survey, architectural plan or engineered design. We will identify any apparent scope limitation during the initial review.

Questions Before You Start

California Site Plan FAQs

Clear answers about documents, turnaround, revisions and the fully online ordering process.

Do I need to visit an office?

No. The complete process can be handled online. You submit the property address, available documents, sketches and photographs through the secure quote form. We communicate by email or phone, send the draft digitally and deliver the completed files electronically.

What documents should I provide?

Helpful documents may include an existing survey, plot map, assessor information, prior plans, a project sketch, property photographs and written permit comments. Submit what you have; we will explain if additional information is needed.

Can you prepare a site plan without an existing survey?

Some projects can be drafted from reliable assessor data, recorded documents and client-provided measurements. Other projects require a current survey or field verification. We review the intended use and available information before confirming the scope.

How long does a California site plan take?

Timing depends on the property, project complexity, document quality and jurisdiction requirements. Most standard projects can be completed within a few business days after all required information is received. Your quote will state the expected schedule.

Do you provide revisions after permit review?

Drafting-related revisions can be completed from clear written correction comments. Revisions that change the project scope or require new professional services may need a separate quote.

Is a drafting site plan the same as a land survey?

No. A drafting site plan is not automatically a legal boundary or topographic survey. When a licensed survey, engineer, architect or professional stamp is required, that service must be arranged separately unless it is specifically included in writing.

What affects the project price?

Pricing may be affected by the lot size, number of structures, proposed work, complexity, available source documents, required calculations, file formats, turnaround and jurisdiction-specific requirements.

Can I receive an editable CAD file?

Editable DWG or other agreed CAD deliverables may be available depending on the selected package and project scope. Confirm the required format before work begins.

Do you guarantee permit approval?

No responsible drafting provider can guarantee a government approval decision. We prepare the agreed drawing scope and can address applicable written reviewer comments, but the authority having jurisdiction makes the final determination.

Which California cities and counties do you serve?

We offer online service across California, including major metropolitan areas and surrounding communities. Submit the property city and county so we can confirm the applicable service and project requirements.
