i know that with the "Barrier to Entry System" you can allow certain ages and genders in doors and stuff. but is there a way to set the locks according to certain job title's? for example if I only want to allow a CEO in the business track to walk through a door and not allow any Power Brokers, is there a mod that will let me do that?

This may be a bit more horsepower than you wanted, but the current version of NRaas GoHere has extensive door locking filters that should do what you require. If you can make a MasterController filter out of the sims intended to be let in (or not let in), such as by career and job level, then you can restrict or allow the door usage accordingly. Note that the most current version of MC and thus its add-ons are required to make the filters work together with GoHere.

If you want to get really creative, you could give them two doors, with the understanding that I have no idea what you are doing here or what the structure looks like. One free one for the executives and one for everyone else that costs §100 or something to get in.

thanks for your help! I'm rebuilding every building in sunset valley for zerbu. so I wanted certain doors only certain people of job title can go through. i'll share it hopefully when im done.
