You can carry however you want on your property. As far as OC say out in the street or the sidewalk, i believe if you have your CHP that it exempts you from the 1k foot rule provided you are not on the school property itself. The 1k foot rule starts at the end of the school property and not the school building itself. I ain't a lawyer, so you may want to check. If you're quite a ways away (say 700') from the school property itself, I wouldn't fret it. I've never heard of someone being charged for simply violating the 1k foot rule without commuting another crime such as drug dealing. Maybe someone will chime in with more insight into this.
Congrats on buying a home!
