Utility Questions to Ask Before Building a Cupertino ADU

Establish what is known about existing services

Gather available records and identify visible equipment with the appropriate professionals. Ask what needs further assessment and which service providers must be contacted. Do not assume spare space in existing equipment establishes available capacity.

Create a list of confirmed conditions and open questions. This helps distinguish a priced connection from an allowance or a future provider decision. Keep that list current as the design develops.

Coordinate equipment with the utility plan

Appliances, water heating, space conditioning and laundry choices influence the systems the ADU needs. Select the intended equipment types early enough for the design team to evaluate the combined requirements.

Discuss where equipment will be located and how it can be maintained. Placement affects usable space, access and the relationship to outdoor areas. A compact floor plan should still leave a practical way to service the systems that support it.

Review routes across the property

Ask how each service will reach the unit and which surfaces may be disturbed. Paving, landscaping, changes in grade and existing underground conditions can affect the work. Coordinate investigation through the responsible professionals before excavation is planned.

Include restoration in the written scope. Reconnecting a utility and restoring a driveway or garden are different tasks, and both may be necessary. Identify what is included and what remains outside the construction agreement.

Clarify approvals and responsibilities

Use Cupertino's building resources to begin the local review. Confirm the applicable requirements with the city, relevant providers and design professionals for the specific property.

Assign responsibility for provider requests, applications, fees and scheduling. Ask which decisions must be completed before other work can proceed. A construction schedule should reflect external dependencies rather than assuming every connection can be arranged at the end.

Questions homeowners ask

Does every ADU need separate meters? Do not assume a universal answer. Ask the applicable providers and jurisdiction about your project, then include the agreed arrangement in the plans and pricing.

Can we price the ADU before utility research? An early estimate may be possible, but it should identify assumptions and unresolved items. A more developed connection plan supports a clearer scope.
