Local notes

Austin’s HOME code changes allow up to three homes on most single-family lots. I draw the site plan, floor plans and elevations for the extra unit and check them against the residential review checklist.

Already in review and stuck at “Awaiting Update”?

Residential work only. We prepare drawings for homes, ADUs, conversions and additions under the state residential exemption, and refer out anything that needs a licensed professional’s seal.
