When you need this permit

  • Governed by the 2021 IBC as locally adopted
  • Confirm fire suppression/alarm scope with the Lyons Fire Protection District; the District's own site (lyonsfire.org/permits-and-inspections) states its plan review period for 'remodeling, new construction, and residential and commercial properties' is 15 calendar days from the date of receipt by the District, and that 'plan reviews and some inspections will require a fee' (amount not published on that page — ask the District at plans@lyonsfire.org). This 15-day figure covers only the Fire District's leg of a multi-agency review, not the Town/SAFEbuilt Building Division's own turnaround.
  • Structural, electrical, mechanical, and plumbing plans required as applicable to the scope of work
  • Solar commercial installations follow the Town's Solar Submittal Requirements (structural engineer letter required for all projects)
  • A related but distinct Town permit — the 'Change in Use/Occupancy (No Work) Permit' for a new business occupying existing space with no permitted work and no change in occupancy type — carries its own confirmed flat $100 fee and a 5-business-day Building/Fire/Planning review period per the Town's 'Start, Move, or Expand your Business' page. This is a DIFFERENT permit from Tenant Finish/commercial tenant improvement (which the same page states has fees that 'vary based on scope of work' with no published numeric review timeline) and should not be confused with it.

Fee schedule

Building Permit Fee (valuation-based, same general schedule as residential new construction)
The Town's Building Permit Fees PDF publishes no distinct commercial-TI flat fee: it carries a single 'Building Permit Fees (Based on Valuation)' table with no residential/commercial split. Show full citationThe Town's Building Permit Fees PDF publishes no distinct commercial-TI flat fee: it carries a single 'Building Permit Fees (Based on Valuation)' table with no residential/commercial split. The Town's own 'Start, Move, or Expand your Business' page says the same thing in words — in its Tenant Finish/Interior Alteration Permit section, fees 'vary based on scope of work' rather than a flat rate. Commercial tenant-finish work is therefore priced off the general valuation-based schedule.

Tips

  • Lyons' published fee schedule does not distinguish a separate commercial tenant-improvement rate from the general valuation-based Building Permit Fee schedule — confirm directly with SAFEbuilt for any project-specific fee estimate on a commercial scope. This is now corroborated by two independent primary sources: the Fee PDF's absence of a separate line, and the Town's Tenant Finish/Interior Alteration Permit page stating fees 'vary based on scope of work.'
  • Confirm fire-suppression/alarm requirements directly with the Lyons Fire Protection District early in design, since it is a separate special district from the Town Building Department and is not covered by the Town's own submittal checklists. Budget for the District's own plan-review fee (amount not published) in addition to the Town's fees.
  • Don't confuse Lyons' 5-business-day 'Change in Use/Occupancy (No Work)' permit review period with the Tenant Finish/commercial-TI permit — they are different permit types on the Town's own business-permitting page, and only the former has a published numeric timeline.
  • If fire-code review applies to your scope, the Lyons Fire Protection District publishes a 15-calendar-day plan-review period on its own site for commercial/remodel/new-construction plans — factor this into your overall timeline alongside the Town/SAFEbuilt Building Division's review, which has no published turnaround.

This is a DIFFERENT permit from Tenant Finish/commercial tenant improvement (which the same page states has fees that 'vary based on scope of work' with no published numeric review timeline) and should not be confused with it.. If your project isn't listed, confirm with Town of Lyons Planning and Building Department (permit processing, plan review, and inspections contracted to SAFEbuilt) at 303-823-6622 ext. 25 (Town Planning and Building Director); 970-545-3512 (SAFEbuilt Permit Technician); 970-545-3555 (SAFEbuilt Chief Building Official); 303-774-0454 (Inspection Request Line) before starting work.

The Town's published fee schedule does not list a distinct commercial tenant-improvement fee; commercial TI work is billed under the same general valuation-based Building Permit Fee schedule used for residential new construction, plus the 65% Plan Review Fee and applicable use taxes. The Town's own Tenant Finish/Interior Alteration Permit page independently confirms fees 'vary based on scope of work' rather than a flat rate, corroborating this from a second source.

The Town has not published a numeric plan-review turnaround for the Tenant Finish/Interior Alteration Permit itself (only a different permit, the Change in Use/Occupancy permit with no construction work, has a published 5-business-day figure). If fire-code review is required, the Lyons Fire Protection District separately publishes a 15-calendar-day review period on its own site for its portion of the review. Confirm the Town/SAFEbuilt Building Division's expected turnaround directly, as it remains unpublished as of 2026-08-02.
