Requirements

• Required by default for any new construction, remodel, or expansion of an existing structure requiring a building permit, EXCEPT construction/remodel/expansion of a single-family or two-family dwelling unit/structure (Sec. 16-5-40(a)(1)) — this covers commercial, industrial, institutional, and multi-family (3+ unit) projects, including commercial shell/new-building/tenant-finish/remodel work
• The Town Manager may waive site plan approval if a remodel/expansion of an existing structure will not increase occupancy, density, employees on site, or parking requirements (Sec. 16-5-40(a)(2)) — confirm applicability/waiver eligibility with the Town before assuming full review is required for a small tenant-finish scope
• No site plan may be approved without a recorded final subdivision plat or proof the structure sits on a legal lot (Sec. 16-5-40(a)(3))
• Application processed under the Administrative Approvals procedure, Sec. 16-5-20: applicant submits required documents 'as set forth in the Development Review Manual' (referenced by the ordinance; a copy of this manual could not be located published on the Town's own website as of 2026-08-02 — verified-negative, not invented)
• No building or construction permit (including the SAFEbuilt-reviewed Building Permit Application) may be issued before site plan approval, absent a specific Board of Trustees exemption after Planning Commission review (Sec. 16-1-95(b)(10))

• An approved site plan order not acted on (structures not constructed) within six (6) months may be revoked by the Town Manager (Sec. 16-5-40(h)); a rezoning of the subject property automatically voids the site plan order unless the Town expressly reaffirms it (Sec. 16-5-40(i))
