Frequently Asked Questions About ADU Site Plans
Every permit is different; use these answers to prepare your scope review and verify project-specific requirements with your permit office.
Is an ADU site plan the same as a full ADU permit set?
No. The site plan primarily establishes placement, setbacks, access and property context. A complete ADU permit may also need floor and roof plans, elevations, foundation, framing, energy and trade drawings.
Do I need to show utilities for a detached ADU?
The permit office may ask for sewer or septic connections, water supply, electrical service, drainage and access. Tell us what utility information is available and what the agency requires.
Can you help locate an ADU converted from a garage?
Yes, the site drawing can distinguish the existing garage structure from the proposed ADU use. The conversion itself may need separate life-safety, energy, building-system and architectural drawings.
What are the starting prices?
The eligible ADU Site Plans package starts at $299. Larger scopes and additional disciplines are individually quoted.
What information should I provide to start?
Send the project address and reviewing jurisdiction, work description, approximate dimensions, existing survey or drawings if available, photos or sketches, and any plan review comments.
Can the drawings be used in my city or state?
We accept remote drafting requests nationwide. The drawing scope must match the specific local requirements. State licensing rules apply whenever regulated surveying, architectural or engineering services are needed.
Is a professional stamp included?
No stamp or seal is automatic. Where required, a properly licensed professional must perform an independent review and accept responsibility before signing or sealing, under a separately agreed scope.
What happens if the permit reviewer requests changes?
Reasonable drawing corrections within the original agreed scope are supported according to the proposal. New design work, surveys and additional engineering are separately assessed.
