Nicene and Ante-Nicene Fathers, Ser. II, Vol. XIV:
The Canons of the Council in Trullo; Often Called The Quinisext Council.: Canon LIX

Canon LIX.

Baptism is by no means to be administered in an oratory which is within a house; but they who are about to be held worthy of the spotless illumination are to go to a Catholic Church and there to enjoy this gift.  But if any one shall be convicted of not observing what we have determined, if he be a cleric let him be deposed, if a layman let him be cut off.

Ancient Epitome of Canon LIX.

In oratories built in houses they shall not celebrate baptism.  Whoever shall not observe this, if a cleric he shall be deposed, if a layman he shall be cut off.
