WHAT TO KNOW FIRST
Stonegate is a planned community where yards, home plans, alleys, and edge conditions differ. A useful ADU study measures the house and lot rather than relying on a model-home plan.
- Parcel or survey material and a note showing which dimensions were field checked.
- Photos from existing bedroom and living-room windows toward the proposed ADU area.
- Gate, alley, and driveway measurements for delivery and staging discussion.
Measure the parcel instead of relying on a model plan.
Stonegate homes that share a plan name can still have different lot edges, orientations, windows, easements, and finished yards. Use the house and lot survey or available parcel information as the base, then field-check walls, drains, equipment, patios, gates, and neighboring openings. Mark every item whose location remains approximate. That discipline keeps a familiar floor plan from creating false confidence about usable area and gives the first contractor conversation a clear distinction between verified dimensions, homeowner observations, and questions for qualified investigation.
Test the proposed footprint against outdoor use, bedroom windows, drainage, equipment clearances, and privacy on both sides of the property line.
Check the route before the drawings advance.
At the Stonegate property, trace deliveries, trenching, worker access, temporary protection, and restoration through the areas the household uses every day.
The route that returns to finished condition
Identify where material can be staged and how finished surfaces, gates, walls, and neighborhood circulation will be protected.
Connection work in the contractor scope
Locate candidate routes, then confirm capacity and connection requirements through the appropriate professionals and agencies.
Written responsibilities before work
Association procedures may address exterior changes, but they do not replace City review or determine state-law eligibility.
Compare privacy and staging before selecting the ADU position.
A footprint that protects the largest patio may face existing bedrooms or leave a difficult material route. Another position may improve privacy but require longer trenches or more landscape repair. A garage conversion can avoid a new yard structure while changing storage and vehicle use. Ask for two plausible arrangements to be compared using the same topics: entrances, window relationships, outdoor circulation, equipment clearances, deliveries, services, drainage, and restoration. This makes the choice traceable to the Stonegate property rather than to a generic rendering.
Test each ADU type against daily life in Stonegate.
For the Stonegate project, compare privacy, storage, parking, outdoor use, and disruption along with the rooms shown on the plan. A workable Stonegate choice has to function during construction and after move-in.
For a Stonegate home, a detached backyard ADU adds a separate foundation, shell, and utility connections. An attached ADU at the Stonegate address adds work where the new unit meets the home.
Choose a garage conversion only after checking the shell and the household functions it replaces. Consider a JADU when qualifying interior space better fits the goal.
Verify these Stonegate inputs before concept selection.
- Parcel or survey material and a note showing which dimensions were field checked.
- Photos from existing bedroom and living-room windows toward the proposed ADU area.
- Gate, alley, and driveway measurements for delivery and staging discussion.
- A list of yard surfaces and landscape features that would need protection or replacement.
