Silverthorne building inspections

Applies to: Accessory Dwelling Unit / Single Apartment Building Permit

1. 1

   Foundation (attached/detached new construction)

   Performed by Summit County Building Department; not applicable to the remodel-of-existing-home ADU sub-type unless new footings are involved

2. 2

   Rough Frame / Rough Trades

   Framing and trade rough-ins before concealment

3. 3

   Final Inspection

   Town final inspections (Planning/Engineering as applicable) plus Summit County final building inspection

Applies to: New Commercial Construction / Commercial Addition / New Mixed-Use (Residential and Commercial) Building Permit

1. 1

   Foundation / Footing

   Performed by the Building Department that reviewed and approved the plans (Summit County Building Department per the Town-wide intergovernmental arrangement)

2. 2

   Framing

   Per the same review-and-inspect department as plan review

3. 3

   Final Inspection (Town Engineering, Water/Sewer, Planning, plus Building Code final)

   The department that reviewed and approved the building permit plans also conducts the final inspections prior to CO/Completion. Building inspection requests are made via the SmartGov portal by 4 p.m. the business day before the desired inspection, per the Permit Process accordion pages. This is not a residential-vs-commercial split with the 5 p.m. cutoff shown elsewhere on the Town's site: the Town's dedicated Inspections page states the SmartGov cutoff as 5 p.m. ('Inspections may be scheduled up to 5 p.m. the business day before the inspection') while also announcing 'On 8/14/26 the cut off time for inspections will change to 4 p.m. the day before the inspection,' alongside a vendor change: 'As of 8/17/26 we will be using Comprehensive Building Code Services for all Building Department inspections and plan review' (replacing the Summit County Building Department in that role). The Permit Process by Project Type accordion pages — residential and commercial alike — already show the post-8/14/26 value (4 p.m.) site-wide, while the Inspections page shows the pre-8/14/26 value (5 p.m.) alongside the change notice. The differing times are a same-site publishing lag around a real, dated policy/vendor transition — the 5 p.m. cutoff applies before 8/14/26 and the 4 p.m. cutoff from 8/14/26 — not a permit-type conflict.

Applies to: Residential Addition / Remodel Building Permit

1. 1

   Foundation (additions with new footings)

   Performed by Summit County Building Department

2. 2

   Rough Frame / Rough Trades

   Framing, electrical, plumbing, mechanical rough-ins before concealment

3. 3

   Final Inspection

   Town final inspections (Engineering/Water-Sewer/Planning where applicable) plus Summit County final building inspection

Applies to: Commercial Remodel / Tenant Improvement Permit (Tenant Finish/Improvement, Landlord Work, White Box, Core and Shell, Change in Use)

1. 1

   Rough Trades (electrical/plumbing/mechanical, as applicable to scope)

   Before concealment; scope-dependent since TI submittal is not a full new-construction package

2. 2

   Final Inspection

   The department that reviewed and approved the building permit plans also conducts the final inspections prior to CO/Completion. Building inspection requests go through the SmartGov portal by 4 p.m. the day before the desired inspection, per the Commercial Remodels accordion page. An apparent 4 p.m./5 p.m. discrepancy between the Town's pages reflects a dated, site-wide policy/vendor change, not a permit-type split: the Town's Inspections page states the SmartGov cutoff was 5 p.m. until 8/14/26, when it changed to 4 p.m., alongside a vendor transition to Comprehensive Building Code Services effective 8/17/26 (replacing the Summit County Building Department for Building Code plan review/inspections). The Permit Process accordion pages — including this one — show the post-8/14/26 value (4 p.m.).
