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.
A permit drawing should be easy to review, aligned with the project scope and supported by responsive communication.
We understand that requirements vary among California cities and counties. Each drawing is organized around the information requested for your particular project and jurisdiction.
Dimensions, setbacks, structures and proposed work are presented in a clean, professional format that is easy for owners, contractors and reviewers to understand.
Most standard projects can be completed within a few business days after receiving all required property and project information.

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