The requirements for membership in the House of Representatives are laid out very early in the Constitution.  They are in Section 2 of Article I of the document.  The requirements are very simple.  A person must be at least 25 years of age before they can be elected to the House of Representatives.  They must have been a citizen of the United States for at least seven years.  They must also live in the state that they are going to represent.  These requirements are lesser than the requirements for the Senate because the House was held to be the less important house of Congress.
