My question involves landlord-tenant law in the State of:
  1. Austin, Texas

Hopefully, someone who knows real estate law in Austin, TX can help with this. HUD prohibits discrimination against parents with children being charged extra rent for having a child if I am not mistaken and I could have that wrong. However, I just read that Austin has protections for married couples as tenants. Can a landlord increase the rent on a one-bedroom apartment because a married couple is renting the apartment as opposed to a single person renting the apartment?
