I am a college student at SUNY Buffalo. I live on campus and I am a firearm owner. There is a way to bring firearms on campus (for storage), but it will take some time before you are able to do so. First you want to contact the chief of police for that university. I sent an email and they said sure, what guns you want to bring. I said a sig556 and a Remington 597. They were hesitant on doing it but realized I was doing the right thing (contacting them before I did it). I am also a NRA RSO and I am applying for a pistol permit to validate it that NRA Certificate. I purchased a M&P Shield and asked them if I could store it there. they said yes I could.
You have to also realize, they can say no. and if they say yes, they might want to meet you before they allow you are allowed to store it there. I have been very lucky, I have gotten to know my campus police and they have gotten to know me. I have also been given permission to start a target shooting club for the college, and the members would be able to store firearms at the police station as well.
Steps
1: call the police station, and ask about safe storing of a firearm at their office when you drop off your daughter.
2: the chief is going to have the final say, so if the phone operator does not know what to do, ask to speak with the chief or their firearm instructor.
3: explain that you want to store an "unloaded firearm" at their station while you are visiting. they will likely take a month or so to decide. (There is a document somewhere online that states that you can store firearms at the office if you go to school there. not sure if it pertains to parents.) you will have to set up a drop-off time and pickup time if they approve of you to use their office as a "safe storage" place. my time frame is 7:30 am -2:30pm weekdays only.
I am not sure if that helps you? but I hope it gives you the right direction to pursue
