In most states, the minimum age of a person signing an apartment lease is 18 according to Lawcheck, a legal sourcebook. In some states, the minimum age requirement is 19 years old.
An apartment lease or rental agreement for an apartment or house is considered a legal contract. In most states, only people who have reached the age of majority are legally allowed to sign a contract. This means that in most states, you cannot sign a lease until you have reached 18 years of age.
There are a few states where the age of majority is 19 years old. These states include Alabama, Idaho and Nebraska. Possible exceptions may be minors who have been emancipated from their parents. States may also have additional requirements such as requiring a co-signer on the rental agreement.
