Your description isn't clear enough, so here's a design that could be used for some interpretations of what you wrote.

0) There are several sites.
1) A check list has several check list items.
2) Each site has a check list with a subset of all available check list items.
3) Each check list item may be on several sites' check lists.

This is a classic many-to-many relationship and the typical implementation is to have (at least) three tables:

Site: ID, Name, etc.
Item: ID, Name, etc.
SiteList: SiteID, ItemID (usually no other data here, but maybe in some cases)

Another schema would allow for defining lists and assigning them to sites:

Site: ID, Name, etc.
Item: ID, Name, etc.
List: ID, Name, etc.
ListItem: ListID, ItemID (usually no other data here, but maybe in some cases)
SiteList: SiteID, ListID (usually no other data here, but maybe in some cases)

This second way may be approriate for your needs, you can define a common list and custom lists and assign multiple lists to the sites. Getting a complete list of all items for a site is simple as well.
