Pratimoksha of the Dharmaguptakas 1.30

1.30

「若比丘！自求作屋，無主，自為己，當應量作。是中量者，長佛十二磔手，內廣七磔手。當將餘比丘指授處所，彼比丘當指示處所，無難處無妨處。若比丘有難處妨處，自求作屋，無主，自為己，不將餘比丘指授處所，若過量作者，僧伽婆尸沙。

If a monk seek to get a house for himself, without a householder, on his own account alone, he must take care to observe the proper measurements; the mean measure ments are these, twelve of Buddha’s spans in length, and within, seven of these spans broad. He ought also to take the body of the monks, to mark out the position of the place given, in doing which they must observe the character of the place, that it be not either dangerous of approach or difficult of access; if the monk, notwithstanding the illegal position, still build his house, or if he take not the monks to inspect it, or if it exceed the lawful measurement, let him be suspended.
