How Sarah from Washington Got Her
Site Plan for a 2-Story ADU Addition

Sarah, a new residential client from Graham, Washington, needed a detailed site plan for a two-story ADU addition to her existing home.

The city required a clear layout showing utilities, setbacks, easements, impervious surfaces, and the exact ADU location before approving the permit.

Order:

Sarah ordered our Gold Package Site Plan, requesting delivery in PDF, DWG, and JPG formats.

She did not require a custom paper size but asked for a comprehensive plan that included all utilities, easements, setbacks, distances from structures to property lines (walls and rooflines), and the ADU footprint.

She also requested an impervious surface calculation as an additional option.

Helpful files included a parcel screenshot and several key dimensions, which gave our team a clear starting point.

OUR SOLUTION:

Using the information Sarah provided, our CAD designers prepared a detailed site plan.

Since no site visit was required, we were able to begin work immediately and focus on accuracy and compliance.

Although Sarah selected a 12-hour delivery, the completed site plan was finished faster than expected, in just 9 hours.

Sarah’s  Gold Site Plan drawing incuded all necessary information like:

  • Property Lines
  • Primary Structure
  • North Arrow
  • Parcel ID
  • Landscape
  • Lawn
  • Swimming Pool
  • Lot dimensions
  • Scale, Roofline
  • Fence, Trees
  • Sidewalks
  • Driveway
  • Paths, Shrubs
  • Parking Spaces
  • Measurements Between Major Features
  • Accessory Structures
  • Well and septic system
  • Additional new structures
  • Topographic Contour Lines
  • Vicinity Map

REVISIONS

Sarah requested two revisions, which were completed quickly and at no additional cost.

The updates refined setback distances and adjusted utility placement for full compliance.

SUMMARY

This project shows how a well-prepared site plan can simplify even complex ADU additions.

Sarah valued the clarity, speed, and collaborative approach, which helped her confidently submit her plans for approval.

Our team ensured every required detail was covered, creating a smooth and stress-free permitting experience.
