Privilege Level Required to Install and Maintain Sharepoint 2013

I am not a Sharepoint expert by any means, and really have zero experience with it. I am however one of our network administrators and domain administrators. The question has come up of how high of a privilege level an account needs to be to install and maintain a Sharepoint installation on servers that are already attached to our domain. I have been told domain admin level, however that seems to me odd and I would not like to have any individuals with that level of access outside of our network admin team. Can anyone provide a quick rundown of the access level required to install and maintain Sharepoint 2013 (and maybe 2010)?
