Commissioners direct staff to start LDR text amendment to align mitigation threshold with state law

Summary
The Board directed staff to initiate a text amendment to Teton County’s land development regulations to consider raising the housing-mitigation exemption threshold (current local exemption 2,500 sq ft) and return with public-noticing and nexus analyses; commissioners debated 3,000–4,000 sq ft options and separate tracks for commercial mitigation.
Teton County commissioners on April 13 asked staff to begin a Land Development Regulation (LDR) text-amendment process to consider raising the square-footage threshold that triggers affordable-housing mitigation.
Commissioner (mover) urged aligning the local exemption with new state permitting rules that create a fast-track for homes under roughly 3,000 square feet, and proposed beginning the formal amendment process at a 3,000-sq-ft threshold so the county can meet statutory timelines. Several commissioners agreed on a two-track approach: pursue a quick amendment for the single numeric threshold while scheduling a second, longer track to study broader mitigation program changes and commercial mitigation.
Commissioners discussed alternatives (3,500 or 4,000 sq ft), the legal nexus basis for fees (the board uses a 2013 Nexus study but staff reported a 2023 Nexus analysis exists with different methodology), and the political trade-offs between preserving mitigation revenue and complying with state law. Planning staff said they can prepare a text amendment and bring back analyses for different square-footage options, anticipated public hearings and planning commission review.
Next steps: staff will begin the LDR text amendment process (public notice, nexus materials, and planning commission review) with a starting proposal to adjust the local exemption to 3,000 sq ft and will present alternative thresholds and economic impacts for board consideration.
