Is airspace needed between stone veneer and OSB.
Is airspace needed between stone veneer and OSB.
(OP)
I am in western NC and working a detail to repair an arch below a porch that has suffered water damage. The arch has an inner frame work of OSB and a stone veneer finish. It doesn't look as though the original contractor placed enough water proofing over the OSB. Is an airspace needed for the repair or is waterproofing around the OSB enough to keep the OSB from rotting?

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

Look at ICC Acceptance Criteria 38 “Acceptance Criteria for Water Resistive Barriers.”
To maintain the weather-resistance of the exterior wall on which stone products are installed, rigid, corrosion-resistant flashing, weep screed and a means of drainage should be installed at all penetrations and terminations of the stone cladding. Flashing type and locations should be in accordance with the requirements of the applicable building code.

If it is a true stone veneer, then treat it like a brick veneer with air space and ties, with appropriate cavity wall waterproofing, through-wall flashing and weeps.
See Chapter 14 of the International Building Code (NC Building Code)
