Inspirational concept overview
A smaller ADU concept focused on efficient space, privacy, and practical rental use.
This is an inspirational design concept, not a permit-ready plan. Feasibility depends on parcel, jurisdiction, zoning, utilities, septic/well, fire access, overlays, and local department review.

- Can the provider confirm service assumptions before plans or deposits are paid?
Zoning questions
- Is this project treated as an ADU, primary dwelling, manufactured home, tiny home, RV, accessory structure, or another local category?
- What setbacks, height, lot coverage, parking, design, and overlay standards apply?
- Which city or county department should confirm the project category before plans are purchased?
Documents to collect

How this concept affects the site plan
Place the 500-square-foot concept only after mapping setbacks, easements, lot coverage, existing structures, trees, drainage, privacy, fire access, and utility routes. Keep enough working space for excavation and construction, and check how windows, entries, meters, condensers, parking, and outdoor space affect the main home and neighboring properties.
What to settle before buying plans
Confirm that the jurisdiction recognizes the proposed structure and use, then establish a realistic buildable area and utility path. Ask whether Studio or 1 bedroom occupancy changes septic sizing, parking, egress, fire review, or service capacity. Price sitework, permits, engineering, utility upgrades, delivery, foundations, and finish exclusions separately from the advertised structure or plan price. A concept is ready for purchase only when the selected plan can be adapted to verified parcel conditions.
Questions for the first design meeting
- Which parts of this rental-focused adus concept are fixed, and which can change for setbacks, orientation, access, or utilities?
- How will the approximate 500 sq ft footprint, entries, windows, and outdoor areas fit the usable part of the parcel?
- Which drawings and consultant reports are included, and which site plan, survey, civil, structural, energy, fire, septic, or utility documents remain separate?
- What assumptions does the preliminary price make about foundation, delivery, grading, trenching, meters, panels, sewer or septic, water, permits, and finish level?
- What parcel fact would most likely force a redesign, added engineering, or a different project path?
