Review a change before it becomes an instruction

Describe the proposed change and ask which drawings, products, or trades it affects. Record the agreed scope and any cost or schedule implications before the work proceeds. A short written record is more useful than relying on different recollections of a conversation at the property.

Discuss your Pasadena project

Share the current Pasadena plans and any changes you are considering. We can discuss the construction scope with those decisions visible, whether the project is a business renovation or a new home.
