Commercial Tenant Improvement / Tenant Finish Permit in Mapleton, Utah

Tenant improvement work is billed under the same general 'Building Permit Major' fee (IBC valuation table x 0.005 multiplier) that applies to any major Mapleton building permit — no TI-specific fee line exists anywhere in the Community Development Fee Schedule. What genuinely remains unresolved is the reach of two commercial-specific mechanisms in Mapleton City Code — a Project Plan/Site Plan application (§ 18.90.070(D), $100, required for commercial 'additions and alterations') and a separate Commercial Impact Fees schedule (per ERU, paid at time of building permit): neither the ordinance text nor any Mapleton-published clarification states whether either one extends to a purely interior tenant improvement with no exterior or floor-area change. The Project Plan ordinance's required exhibits (site plan, building elevations, a conceptual landscaping plan, a conceptual signage plan) are all exterior/site-level items a pure interior TI project could not meaningfully produce, which suggests interior-only work may fall outside its intended scope — but that is an inference from the ordinance's content requirements, not a stated interior-TI exemption, and is not asserted here as a settled fact. Confidence stays partial specifically because of this open applicability question, not because of the timeline (which has the same known, statute-confirmed gap as the commercial-building-permit entry).

When you need this permit

  • Interior tenant-improvement or finish work within an existing commercial building, regulated by the adopted 2024 IBC (Mapleton City Code Ch. 15.04)
  • Application submitted through the MyGovernmentOnline (mgoconnect.org) online portal, the same portal used for residential and new commercial permits
  • UNRESOLVED: whether Mapleton City Code § 18.90.070(D)'s Project Plan/Site Plan application — required for commercial 'additions and alterations' — extends to a purely interior tenant improvement with no exterior or floor-area change. The ordinance text does not carve out interior-only work; its required exhibits (site plan, elevations, landscaping plan, signage plan) are exterior/site-focused, which suggests it may not apply, but this is not an explicit, published exemption. Confirm directly with Community Development, (801) 489-6138, before assuming a specific TI project is exempt from the $100 Project Plan fee.

Tips

  • Mapleton does not publish a dedicated tenant-improvement fee, checklist, or timeline — confirm project-specific requirements directly with Community Development (801-489-6138) before submitting.
  • Applications for tenant improvement work go through the same MyGovernmentOnline (mgoconnect.org) portal as new construction and residential permits.
  • Whether the $100 Project Plan/Site Plan application (Mapleton City Code § 18.90.070(D), required for commercial 'additions and alterations') applies to your specific TI project is genuinely unresolved from the published ordinance text — its required exhibits (site plan, elevations, landscaping plan, signage plan) are exterior/site-focused, which suggests a purely interior tenant improvement may fall outside its intended scope, but no explicit interior-TI exemption is published. Ask Community Development directly whether your project needs this application.
  • Mapleton's separate Commercial Impact Fees schedule (Public Safety, Culinary Water, Pressurized Irrigation, Sanitary Sewer — paid per ERU at time of building permit; see mapleton.org/Commercial%20Impact%20Fees%201-9-24.pdf) is written for development generating new demand. Whether a same-footprint interior TI (no floor-area increase, same use category) triggers additional impact-fee liability is not addressed in the published schedule — a change of use to a higher-intensity commercial category (e.g., Assisted Living vs. general Commercial) could plausibly trigger a differential fee. Confirm with Community Development for a specific project.
