Commercial Building Permit (New Commercial Construction) in Northglenn, Colorado

Required for new commercial construction in Northglenn. The City's Building Division (operated under contract by SAFEbuilt) publishes a dedicated 'New Commercial Plan Submittal Procedure' checklist, distinct from and more extensive than the residential submittal list — full stamped architectural/structural/electrical/mechanical/plumbing/fire-protection plan sets, a soils report, and a special-inspections list are required. Routed through CommunityCore's 'Plan Review Permit' track and reviewed under the 2021 IBC as locally amended.

When you need this permit

  • Building permit application must state project description, square footage, total project valuation, electrical valuation, type of construction, and occupancy group
  • All architectural, structural, electrical, mechanical/plumbing, and (if part of the design) fire protection plans must bear the original seal of a Colorado-licensed architect or engineer, per C.R.S. 12-4-112, unless specifically exempted; electronic stamps are accepted
  • Architectural plans must include: floor plan, wall section details, building section, fire-resistive construction details, means of egress including the path to the exit discharge, and a code summary
  • Electrical plans must include load calculations, one-line diagrams, and fault current analysis
  • A soils report (stamped by a Colorado-licensed soils engineer) and structural calculations (stamped by a Colorado-licensed structural engineer) must be submitted electronically
  • A list of special inspections required by the Building Code, and detailed drawings for fire-rated floor/ceiling, roof/ceiling, and wall assemblies, must be submitted
  • The cover sheet must include a building code summary and stated assumptions for occupancy, construction type, total allowable building area, exiting/occupant load, wind speed design, snow load, and frost depth
  • Documentation showing compliance with the 2021 IECC (Energy Code) is required
  • All commercial flat roofs require a plan review (submittal requires installation instructions for the roofing system, fire classification, insulation R-value above/below deck, wind classification, and building height) — this is a distinct, stricter track than the same-visit Quick Permit that applies to standalone residential reroofing
  • Restaurants and commercial kitchens carry additional plan-submittal requirements: a grease interceptor for grease-producing operations; an approved fire sprinkler system for restaurants over 5,000 SF; Type I hoods where cooking produces grease/smoke, Type II hoods for heat/steam-only equipment; two remote exits (not through the kitchen/storage) for an occupant load of 50 or more, with panic hardware; a seating plan for indoor/outdoor dining; and Adams County Health Department approval as a Certificate of Occupancy prerequisite
  • North Metro Fire Rescue District plan review applies; Adams County Health Department review applies to commercial projects involving food preparation or child care
  • All contractors (general, electrical, mechanical, plumbing) must hold a current City of Northglenn contractor license and be listed on the permit before issuance Contractor
  • Although not required, SAFEbuilt advises a pre-submittal meeting with SAFEbuilt and the fire protection district, with a building code summary and question list submitted to SAFEbuilt beforehand
  • The approved, emailed plan set must be printed as one full-size color copy and kept on the job site throughout construction, including through final inspections

Tips

  • Northglenn's commercial submittal list is significantly heavier than its residential list — full stamped plan sets across five disciplines, a soils report, structural calculations, and a special-inspections list are all required electronically before the plan review clock starts.
  • Budget for the correct commercial review tier: 14-20 business days if the project is valued under $1 million, 21-30 business days at or above $1 million — a meaningfully longer window than the 10-14 business day residential figure.
  • Restaurant and commercial-kitchen buildouts carry extra plan-submittal triggers (grease interceptors, hood types, sprinklers over 5,000 SF, egress/panic-hardware rules, health department sign-off) that a generic commercial permit checklist won't surface — confirm these against the City's dedicated 'Restaurants & Commercial Kitchens' requirements sheet.
  • Unlike residential reroofing (a same-visit Quick Permit), commercial flat roofs always require a full plan review — don't assume a commercial reroof can be handled as a Quick Permit.
  • SAFEbuilt (which staffs the Building Division) advises, though does not require, a pre-submittal meeting to review the intended documents before formal application — useful given the size of the commercial submittal package.
