Identifying the client establishes to whom the inspector's duties run, and those duties are substantial. Confidentiality means the report belongs to the client and is not disclosed to the seller, the agents or anyone else without permission — a distinction that matters constantly, since other parties are frequently present and interested. The reporting obligation runs to the client too: findings are communicated to them, and pressure from a referral source to soften or redirect that communication is resolved by remembering whose inspection it is. Ambiguity is common in practice — a buyer's agent may schedule and even pay, a relative may attend, an investor may be buying through an entity — which is exactly why the question is settled before work begins rather than after a dispute.
