Legal description necessary for lease agreement?

[Wei Xie]

Dear BP members,

I am studying for Cal Real Estate Principles course for my salesperson license. The textbook suggests

"... a contract that conveys an interest in real estate must:

 * be in writing

  * contain a legal description of the property

  * be signed by one or more of the parties

..."

While I have seen plenty of sales contracts employing legal description, i.e., lot and block, I have never seen any lease that involves such descriptions. All the leases that I see use street address. Is it really necessary?

Thanks, -Wei
