Is an owner's representative the same as an estate manager?

No. Owner's representative is a fiduciary posture — one person holding delegated authority on the principal's behalf with no financial interest in vendors. Estate manager is a household role; it may or may not be fiduciary.

Which one do I need for a residence?

For construction, renovation, or a purchase-close activation, you want an owner's representative. For ongoing household operation, you want an estate manager. In a residential owner's-representative firm, one senior operator holds both postures across the life of the residence.

Can one person be both?

Yes — and in a small representative firm, that is the model. One senior operator holds the fiduciary duty across the residence's life, engaging specialists (including traditional estate managers) as the mandate requires.

Comparison

Owner's representative vs. estate manager

Two words that get used interchangeably — and shouldn't be. One describes a fiduciary posture. The other describes a household role. Confusing them is how principals end up paying twice for work they never approved.

The short answer

An owner's representative is a fiduciary. One person, engaged by the principal, holding delegated authority to act on their behalf, with no financial interest in the vendors or specialists directed. The posture originates in commercial construction and is now applied to private residences.

An estate manager is a household role. Traditionally staff; increasingly a small firm. The role may or may not be held to a fiduciary standard — that depends on how the engagement is written.
