It's not like it's going to be a meadow by memorial day. It probably won't even violate city code. I typically only mow once every 3 weeks and it's never higher than maybe 4 or 5 inches. Depends on the grass type, shade vs light, the amount of rain, etc. Some places like Mt Lebanon are stricter than the city. But it's doable and not a snake and tick haven by that point.
