Plan a small-home community

Four tools take a project from a real California parcel to a to-scale layout you can walk through with your team.

How the planning tools fit together

  1. Find a parcel. Parcel search queries the county's own public GIS service from your browser. MicroHom shows only the fields that county sends back.
  2. Lay out homes. Open the parcel in the community planner and place home types. Costs use cited public data; anything not yet sourced is marked and left out of the total.
  3. Check the walls. The Block Builder counts hempcrete blocks for a small home using a published US block price.
  4. Walk it with the team. The 3D Walk lets an owner, builder, project manager or inspector move through the same to-scale plan.

Planning only. These tools produce concept layouts, not construction documents. A licensed California architect or engineer must prepare or review anything that is built.
