Is there a charge for after-hours emergency calls?

Usually there is a structure rather than a simple yes, and the structure tells you more than the price does. Common arrangements: an answering service that takes the call and pages an on-call manager, an in-house rotation, or a dispatch service that contacts a vendor directly without waking anyone at the management company.

Each fails differently. An answering service is cheap and often just takes a message. Vendor dispatch is fast but nobody with authority is deciding whether the work is warranted. An in-house rotation is the most responsive and the most expensive.

Ask what counts as an emergency — most companies maintain a defined list, and if a burst pipe in a common wall is not on it you want to know now. Ask the response commitment in minutes, whether it is contractual or aspirational, and what happens when it is missed.

On the money: some firms include after-hours in the base fee, some bill per call, and some bill the manager's time at an overtime rate. Get the rate and the definition together. A per-call charge with a narrow emergency definition is a different product from an inclusive one.
