The starting point. Start with the people who will live there and the part of the property available for construction. Then choose the ADU type after access, structure, services, coastal review, and daily use are visible.
Choose the project type after looking at the site.
A detached ADU creates a separate building. A garage conversion starts by testing an existing shell. An attached ADU meets the original roof, walls, foundation, and systems. A JADU stays within a single-family residence.
We compare those four routes against the household goal, usable yard, garage condition, occupied rooms, privacy, and the construction path. The familiar label is less important than the work needed to make a complete home.
Coastal location belongs in the first property check.
Huntington Beach’s coastal zone does not cover every address, and a coastal location does not answer every project question. Use the City mapping and confirm the proposed work with the responsible authority before describing a review path.
See our coastal-zone ADU guide. It separates parcel location, project scope, and agency response so a general map observation does not become an unsupported approval claim.
Trace the work from curb to finished room.
Delivery access, foundations or existing-condition repairs, weatherproofing, utilities, mechanical equipment, drainage, interiors, and restoration form one construction story. The estimate should show which pieces are confirmed and which still need investigation.
Read the utility and site-work guide and Huntington Beach ADU cost guide. They help compare proposals that may put the same task in different categories.
Plan the job around the occupied home.
Most homeowners keep living on the property. Discuss gates, security, children and pets, dust control, work areas, temporary interruptions, parking, deliveries, and the route to the main entrance before mobilization.
A useful contractor conversation makes the disruption visible alongside the finished design. The construction process explains how those responsibilities move from site review into a written scope.
Bring the address and the idea to the team.
