Denver Community Planning & Development (CPD) — Development Services / Building Inspection
Denver, CO · Licensed Professional Engineering
Site engineering that clears local review — grading, drainage, and utilities designed to each jurisdiction's published standards from day one.
Civil work in Denver combines cold-climate site design — frost-depth foundations, snow storage, and de-icing — with a demanding stormwater regime. The city and the Mile High Flood District (MHFD/UDFCD) criteria govern detention, water-quality capture, and full-spectrum drainage, and Denver enforces green-infrastructure and post-construction stormwater requirements that consume developable area. Expansive Front Range soils affect subgrade, utility trenching, and pavement design, and water/tap coordination runs through Denver Water. Because Denver is a home-rule city with its own code and sustainability overlays, we align grading, drainage, and green-infrastructure features with both CPD and MHFD standards in the first site-plan pass.
Code adoptions and local amendments change on multi-year cycles. The state source verification date is 2026-07-28; we verify the governing editions with Denver Community Planning & Development (CPD) — Development Services / Building Inspection at project kickoff.
Plan review runs through Denver's online permitting system (the E-Permits / Denver Development Services portal) with published commercial review timelines and an expedited option for qualifying projects. Denver reviews building, zoning, and fire concurrently on larger projects, and green-building and energy-code reviews are integrated into the commercial package, so early coordination with CPD helps sequence the reviews.
Denver adopts and amends the I-codes as a home-rule city, so the Denver Building and Fire Code differs from surrounding jurisdictions on the same base year. The city's Green Buildings Ordinance requires cool roofs plus solar, green roof, or energy/renewable alternatives on larger buildings, and Energize Denver benchmarking and performance requirements apply to existing commercial and multifamily buildings above size thresholds.
Xcel Energy applies commercial demand charges and offers time-of-use and demand-response programs; large new services and electrification-driven loads can carry meaningful transformer and interconnection lead times. Natural gas is also Xcel, and water is Denver Water, whose tap-fee and capacity requirements factor into project budgets and site planning.
Denver construction is driven by aerospace and defense, healthcare and the Anschutz medical campus, life sciences, downtown and RiNo/River Mile mixed-use and multifamily development, data centers, and transit-oriented projects along the RTD lines. Sustainability policy — Energize Denver and the Green Buildings Ordinance — is a defining feature of the commercial market.
