When someone is running for the house of represenatives do they have to live in the district that they are running for?

Yes, candidates running for the House of Representatives must reside in the state they wish to represent, but they are not required to live in the specific district at the time of their election. However, it is common practice for candidates to establish a connection to the district through residency, as this can enhance their appeal to voters. Each state may have its own laws regarding residency requirements, so candidates should be aware of those regulations.
