ADU Site Plan
Included when required by the project scope and reviewing authority.
Complete ADU permit drawing packages for applicable California detached, attached, garage-conversion, and junior ADU projects.
SitePlan California prepares and coordinates permit-focused drawings for projects throughout California. The exact deliverables are defined around the property, proposed work, available source information, and reviewing authority requirements.


A complete ADU permit set can include the site plan, floor plans, elevations, roof plan, sections, structural drawings, and applicable MEP information. The exact package depends on the ADU type, existing property, and local review requirements.
We begin with the property address, current plans or available records, a description of the proposed work, and any written plan-check comments. From there, we identify the drawings and professional disciplines that belong in the permit package.
For broader multi-discipline projects, our Full Permit Drawing Sets service can coordinate site, architectural, structural, and MEP information into one package.
A full ADU set should coordinate the site plan, architecture, structure, and applicable MEP work around the same unit type, footprint, and existing property conditions.
Related services include ADU & JADU Site Plans, Residential Permit Plans, Garage Conversion Plans, Foundation Plans, Electrical Plans, and Plumbing Plans.
The exact requirements vary by project, but these are common situations where full adu permit sets may be needed.

Permit drawings work best when dimensions, proposed work, existing conditions, and professional notes agree across the set. We coordinate the relevant information before the package is finalized so reviewers are not comparing conflicting versions of the project.
Where engineering, surveying, architecture, or another regulated discipline is required, the appropriate licensed professional remains responsible for that technical work.
Some full adu permit sets projects are straightforward drafting assignments, while others involve licensed engineering or another regulated professional service. We identify that distinction during scope review rather than implying that every sheet receives a stamp or professional seal.
Deliverables are based on the agreed project scope and may include the drawing types listed above, permit notes, revision sheets, supporting details, or professional documents when applicable.
Some projects require work prepared, reviewed, signed, or sealed by a licensed architect, engineer, land surveyor, or other regulated professional. Those requirements are identified during scope review and coordinated appropriately. Permit approval remains the decision of the reviewing authority.
Common questions about scope, source information, professional coordination, revisions, and delivery.
Send the property address, project description, and any plans, survey, sketches, photos, or permit comments you already have. We will review the information, define the likely drawing scope, and explain the appropriate next step.
