Short answer
Architecture fees may not include engineering, surveying, permit fees, energy reports, arborist reports, interior purchasing, builder pricing, or construction administration unless the proposal says so.
Consultants are often separate
Structural engineers, surveyors, geotechnical engineers, energy consultants, and arborists can be necessary and separately billed.
Permits are not just paperwork
Plan check fees, school fees, impact fees, utility upgrades, and resubmittal work can all show up outside the design fee.
Construction support varies
Some architects include construction administration; others price it separately. Know this before a builder starts asking questions from the field.
