Before a proposal

Three things must become clear.

  1. 01Is this the right project type?
  2. 02What does this property require?
  3. 03What is included in writing?

A service page is an orientation tool—not a permit decision, survey, construction document, final price, or guaranteed schedule.

How the scope is defined

Turn a service name into a buildable, written project.

The same service can involve very different work on two properties. These three stages keep the assumptions, responsibilities, and decision points visible.

  1. 01 · Existing conditions

    Start with the property and intended use

    Review the address, available records, existing structures, access, utilities, and the outcome the homeowner wants.

    • Property identity and available records
    • Existing conditions and known constraints
    • Desired use, capacity, and priorities
  2. 02 · Coordinated scope

    Define what the project actually includes

    Translate the selected service into a property-specific scope, with the disciplines and approvals that the project requires.

    • Design and engineering inputs as required
    • Agency, utility, and permit coordination
    • Selections, responsibilities, and exclusions
  3. 03 · Written decisions

    Confirm before downstream work begins

    Document the verified assumptions, unresolved items, deliverables, price, and schedule before relying on the scope.

    • Verified inputs and remaining unknowns
    • Project-specific proposal and documents
    • Decision gates, changes, and acceptance

The useful next decision

Confirm the property before committing to modern adu.

A preliminary property review can identify available records, missing information, map corrections, and an early fit direction. Professional review still controls final design and approvals.

Have a specific property or question?

Share the address and intended use so the conversation starts with the correct context.
