When you need this permit
- Listed as 'Commercial Alteration' on the Building Permit Application (distinct checkbox from 'New Commercial')
- Plan Review Permit track: two identical scaled drawing sets required
- All contractors must hold applicable City of Castle Pines contractor licenses Contractor
- No Castle-Pines-specific tenant-improvement submittal checklist is published; the general Plan Review Permit submittal standard applies (site plan/floor plan/construction details as applicable to scope). The City's live Building Design Guides and Resources page lists guides for Additions, Residential Basement Finish, Pole Barns, Accessory Structures, Residential Swimming Pools, Uncovered Decks and Porches, Re-Roofing, Asbestos Testing and Abatement, and Residential Fire Sprinkler Systems only — no Commercial Alteration or Tenant Improvement guide is published. This is a confirmed absence on the current page, not an inference.

2026 Fee Schedule (effective document dated May 2026), Building section, 'Building Permit Fees' table. This valuation-tier table is a single unified schedule that is NOT split by residential vs. commercial — the City's own fee-schedule PDF shows only one 'Building Permit Fees' table under the BUILDING section heading, immediately followed by a separately-labeled 'Electrical Permit Fees' line ('As outlined by State Statute'), which IS explicitly the only building-related fee split by residential/commercial in this schedule. Commercial tenant-improvement valuation fees therefore follow the same table as residential, not a different one. Independently corroborated by the City's Building Permit Application form (PDF), whose 'For Office Use Only' fee-assessment block (Building Permit Fee / Plan Review Fee / Zoning Fee / Castle Pines Tax / Douglas County Tax) is a single shared set of fields used regardless of which Permit Type checkbox is selected, including 'Commercial Alteration.'2026 Fee Schedule, Building Permit Fees table, page 5.

2026 Fee Schedule, Building Permit Fees table, page 5. The published row closes with “up to and including $100,000.00”, repeating the ceiling of the tier below it; every other tier closes at its own ceiling, so the $500,000.00 bound recorded here reads the table as the City evidently intends. Confirm with the City before relying on it for a project near the tier boundary.Review timeline
