Look into the B105; three pages of basic material.
That said, you will want to talk with your legal counsel about things to be added or changed in California (and elsewhere).
Such as:
Statement that this agreement is the agreement and any changes need to be in writing.
Mutual waiver of consequential claims (may be a topic of California law)
Limitation of liability (perhaps to "fees paid")
Lien rights (again, California Law)
Whatever you may want to include regarding release of liability for anything that happens during construction if they don't involve you in construction administration - see recent discussion here.
The "for the following Project" part of page one is the place to describe the project in as much detail as you can. If you say "1 bedroom addition" and later the Owner(s) decide 2 bedrooms are needed - document that and see it it impacts your fee, schedule, project budget, etc.
Welcome to the club.
