These three gentleman above have nailed it.
As a snarky response, you all need to have the "need" in your area of performance
venue, and your
venue shouldn't be terrible (either with the politics, headache, of dealing with the school board)
Here in North Jersey, high schools being used by local community events not affiliated with the Board of Ed, or even from neighboring towns is status quo. It does generally require some
level of "Theater technical director/ facilitates manager" to manage the scheduling and incidentals of a rental contract. You may be surprised how many School Boards are not equipped with that staffing position to look after what is probably the most advanced/expensive room in a school. It may take a little doing to staff developed to engage in rental opportunities. Many schools are not equipped nativity to participate in the rental business.
It can be a lucrative for schools to do get in the business if there money exists in the area to support both the schools costs, + profit, with out leaving the rentee in the poor
house.
Local high school near me, charges 75$/hr for 2 staff members to be present (lx and sound) 50$/hr for
Deck manager (usually student
stage manger) + School security rate and 5000$ for 12 hours to just be in the theater. Those pay rates are 1.5x after 8 hours as well
. During dance season, dance comps and dance recitals are paying those rates that for 2 months straight, and still are making money
hand over fist from ticket, DVD sales
etc. This might be an outlier scenario but it's something you can strive for.
