How this project moves from idea to construction.
The sequence is adjusted for design, engineering, permits, inspections, selections, procurement, existing conditions, and the responsibilities stated in the signed contract.

A useful budget starts with the complete scope.
Online ranges can help with early planning, but they are not bids or price guarantees. These project conditions commonly affect the final cost:
- New detached construction versus conversion of existing space
- Site access, demolition, grading, drainage, and foundation requirements
- Utility capacity, trenching, meters, sewer, water, electrical, and HVAC
- Plans, engineering, energy, fire, school, permit, and impact requirements
- Kitchen, bathroom, windows, doors, exterior materials, and finish level
- Condition and legal status of an existing garage or accessory structure
Common homeowner questions.
Is every garage suitable for conversion?+
No. Foundation, framing, height, moisture, fire separation, utilities, parking, zoning, and legal status must be reviewed for the specific property.
Can you price an ADU without plans?+
Only as a broad early planning discussion. Reliable construction pricing requires enough design and site information to define the work.
Who handles permits?+
Responsibility is defined in the proposal or signed agreement. Design professionals, owner documents, utility coordination, fees, and jurisdictional requirements may involve separate parties.
