My studio is in a residential area in sp too... When the neighbours saw the truck bringing all those wierd materials... I tell then that music is my weekend hobby (wich is a complete lie) and those materials was just to make sure I will not ever bother them with noise.
So they said: "Ah, good luck with your hobby and thx for invest in the acoustic isolation".
They don't even know that I run session heres 24/7 and that's how I feed my family.
Good luck with your studio bro!!
By the way... I'm now bulding a small warehouse to keep my instruments and I'm facing the same delay problems...
