PERMIT PLANS & DRAWING SUPPORT

ADU Plans for Your Next Project

Plan a detached backyard dwelling, attached accessory unit, or conversion with documentation that reflects the existing property and proposed living space. Whether you are preparing a first permit application or responding to comments, we help organize the relevant documentation based on your project details and local review requirements.

Start with your property address, basic dimensions, and any survey, drawings, photos, or comments you already have. We will review the information and explain a proposed drawing scope before work begins.

What Are ADU Plans?

ADU Plans are project-specific documents used to communicate the proposed construction, site placement, existing conditions, or related changes to permitting reviewers and construction participants. Their exact content depends on the kind of work, available source information, and the jurisdiction’s requirements. Our service focuses on preparing clear, coordinated drawings for the agreed scope rather than assuming that every project needs the same sheets.

We pair real-world project context with clear drawing documentation so the scope is easier to understand before drafting begins.

Why choose Make A Site Plan?

Focused documentation

We distinguish site-only, partial and multi-discipline permit packages so you can request the appropriate scope.

Simple remote intake

Send your address, survey, photos and project notes online instead of guessing technical sheet names.

Clear communication

The quote explains intended deliverables and information still required from you.

Coordinated support

Architectural, structural, MEP and professional review needs can be identified and scoped as applicable.

Frequently asked questions

Can you design an ADU without an existing house plan?

We can begin with the address, survey and available property records, but accurate existing conditions and a current survey may be required before finalizing the permit scope.

Are engineering and energy reports included?

They are included only when specifically listed in the quote; licensing, energy compliance and other studies depend on jurisdiction and project.

How much does this service cost?

Pricing depends on project size, complexity, existing documentation, local requirements and whether engineering, calculations or additional sheets are needed. We provide a scope-based quote after reviewing the project.

Can you guarantee permit approval?

No. We prepare the agreed documents for permit submission and can review subsequent comments. Approval and any required inspections remain under the jurisdiction’s authority.

How fast can the drawings be completed?

Timing depends on the documents supplied, project complexity, revisions and any independent professional review. The project quote will state an estimated schedule.

Can I request changes after receiving the drawings?

Yes. Mark changes directly on the PDF or send a consolidated list. Revisions within the original scope are addressed according to the agreed terms; new design work is quoted separately.

Professional engineering/architecture review and sealing are never automatic. Licensed professionals make independent determinations where applicable, and final permit approval remains with the governing jurisdiction.
