The short answer

Treat an owner-requested change as a new decision with a scope, credit or cost and schedule effect. Approve the whole consequence, not just the attractive product or revised layout.

Identify the current commitment

Check what was approved, ordered or installed before requesting the change. Ask whether the old product can be returned and whether completed work must be removed. A substitution that appears equivalent on a store page can have different dimensions, electrical needs or installation requirements. Give the contractor the actual specification, not only a marketing photograph. See CSLB consumer guidance for the applicable official information.

Request a net proposal

Ask for additions and credits to be shown clearly. The cost is not always the difference between two retail prices. It can involve handling, rework, changed labor or effects on other trades. Equally, do not assume every deleted item carries no credit. Ask the contractor to explain the calculation against the existing agreement.

Ask about downstream decisions

Find out whether the change affects inspection, drawings, delivery, access or later work. Record the decision deadline. A choice made too late can delay a whole sequence even if installation itself is simple. The owner should understand that effect before approving rather than discovering it when the finish date moves.

Close the communication loop

Use the agreed approval route and update the selection log, drawings and change order. Confirm that the site team has the new information. Keep the old selection marked as superseded rather than leaving two unlabelled versions in circulation. After installation, check the approved result and record completion.

A selection-change checklist for owners

Start by locating the current approved item and its commitment status. Has it only been discussed, formally selected, ordered, delivered or installed? Those stages affect the practical consequences of changing it. Ask the contractor to identify the actual stage rather than assuming that nothing has happened because the item is not visible on site.

Provide the complete proposed replacement specification. Include dimensions, finish and accessories when relevant. Ask who needs to confirm compatibility. A new appliance can affect cabinetry or utility connections; a different tile format can affect layout and trim. The purpose is to discover those relationships before approving the change, not to create surprise charges afterward.

Request the net financial effect, including any credit, return charge or rework. Ask which part is firm and which remains an estimate. A different retail price alone does not establish the total change. Keep the contractor’s explanation with the proposal so you can understand the basis later.

Request the schedule effect in terms of tasks and dependencies. Does the change delay ordering, inspection, another trade or only one final item? Ask whether an alternative sequence is possible and what limitations it has. Do not pressure the contractor to promise no delay when a real dependency exists; decide whether the change is worth its documented consequence.

After approval, update the selection register and mark the old item superseded. Confirm that the relevant installer, supplier and designer have the new version. Check the installed result against that version and close the change log entry. This completes the owner’s decision process. Without the final communication step, a perfectly priced change can still fail because someone builds from the previous plan. Keep any unresolved issue visible instead of assuming that signing the change automatically notified everyone involved.

Follow through on the decision

Before sending the final choice, check that all decision-makers in the household agree and that the selected item is actually available on the terms discussed. Ask the contractor to confirm receipt of the approved version. Do not rely on a text containing several possible products with no clear selection. Mark alternatives as rejected or pending. When the revised item arrives, compare it to the approved specification before installation where practical. Keep any substitution proposal separate and ask about its effects. This final loop protects both the owner and contractor from building an option that was merely considered. It also gives the project a clear record of when the decision became complete, which can matter when discussing later schedule effects.

Decision checklist

  • Check whether the existing item is ordered, delivered or installed.
  • Provide a complete replacement specification for the relevant compatibility review.
  • Request additions, credits and schedule consequences in a net proposal.
  • Confirm the approved version reaches suppliers and the installation team.

A sink changes after cabinet ordering

Hypothetical example. Imagine a wider sink is selected after cabinets are ordered. Ask whether the cabinet, countertop cutout, plumbing and delivery schedule are affected. A meaningful change proposal addresses those interfaces. Comparing only the price of the two sinks misses the decision the project actually needs.

Related questions

Can a no-cost change affect the schedule?

Yes. Record both dimensions separately.

Who should approve the change?

Use the named owner representative and contractor approval route so a casual crew conversation does not become ambiguous authorization.
