AI plan check in Aurora, CO
Aurora is a separate jurisdiction with its own adopted code and its own department, which surprises teams that treat the east metro as an extension of Denver. City of Aurora Planning and Development Services reviews against the 2021 IBC with Aurora amendments, and two overlay regimes apply here that do not exist next door: airport requirements tied to proximity to Denver International, and compatibility zones around Buckley Space Force Base. AI plan check reads the set against Aurora's own code and those overlays before the first correction cycle.

Why Aurora's Building Code Matters for Your Drawing Set
Aurora adopts the 2021 IBC with its own amendments, administered by Planning and Development Services. Because Colorado leaves code adoption to local government, that package is genuinely distinct from Denver's, from Boulder's, and from Fort Collins', so verifying the adopted edition is the first step on any project crossing metro boundaries. Two overlays then shape the site work. Proximity to Denver International Airport puts parcels under airport overlay requirements that reach height, lighting, and use, and those constraints belong on the site plan and elevations before massing is fixed. Buckley Space Force Base adds compatibility zones covering similar concerns near the installation. The physical conditions follow the Front Range pattern: expansive bentonite clay makes foundation type a geotechnical determination rather than a default, and elevation reduces air density enough that combustion equipment and air handling need altitude-corrected values. Aurora also covers a very large land area, so site conditions, service availability, and applicable overlays vary considerably between the older west side and the newer development on the eastern edge.
How the City of Aurora Planning & Development Services Reviews Construction Drawings
Planning and Development Services runs review for the city, and standard commercial work generally lands between 3 and 8 weeks across building, structural, mechanical, plumbing, and fire reviewers, with site, drainage, and zoning handled alongside. The overlay determinations are the piece worth resolving first, because airport and base compatibility requirements affect height, lighting, and sometimes use, and a late determination invalidates massing and elevation work rather than producing a detail correction. Medical campus projects at Anschutz and Fitzsimons operate at a different depth: institutional occupancies, laboratory containment, imaging equipment, and essential electrical systems mean the mechanical, electrical, and structural reviews are all substantive and interdependent, and a change in one usually reaches the others. Growth on the eastern side of the city adds infrastructure and service questions to site review that established parcels do not carry. Settle overlay status, geotechnical conditions, and utility service before the technical set is finalized.
Common Plan-Check Issues in Aurora
The most avoidable failure in Aurora is jurisdictional: a set drawn to Denver amendments, submitted in Aurora, corrected against Aurora's adopted code. After that, the findings cluster in three areas. Overlay conflicts come first, with building height, rooftop equipment and screening, exterior lighting, and antenna or crane provisions that were never checked against the airport or base compatibility limits, and those corrections change the building rather than the detail. Expansive bentonite clay produces the structural cluster: conventional slab on grade specified where the geotechnical report calls for drilled piers with void form and a structural floor, pier schedules without void form, and slabs detailed without the separation that keeps interior partitions off a heaving floor. Altitude generates the mechanical cluster, where combustion equipment and air handling were sized from sea-level catalog values. Healthcare and laboratory work adds a fourth pattern of its own, with containment, exhaust discharge locations, redundancy, and vibration criteria under close review because the base building rarely anticipates the eventual equipment.
Aurora Project Types and What They Require
The Anschutz Medical Campus at Fitzsimons anchors the city's most demanding work, producing hospital, clinical, research laboratory, and bioscience buildings whose compliance footprint reaches every discipline: institutional life-safety compartmentation, medical gas, essential electrical systems, laboratory containment and exhaust, vibration criteria for imaging and research equipment, and infection control during phased construction inside occupied facilities. Industrial and logistics development takes advantage of Aurora's land supply and airport access, bringing high-piled storage classification, sprinkler design density, long-span structure, and dock loading. Multifamily construction has followed the city's growth, carrying accessible unit distribution, fire separation, and cold-climate envelope performance. Mixed-use development adds occupancy separation and ground-floor requirements. Work near Buckley Space Force Base picks up compatibility requirements on top of whatever else applies. A research building and a distribution center share a jurisdiction and almost nothing else in the review.
Aurora Plan-Check FAQs
Does the Denver Building Code apply in Aurora?
No. Aurora is a separate jurisdiction that adopts the 2021 IBC with its own amendments and runs its own review through Planning and Development Services. Colorado has no statewide commercial building code, so adoption is local and Denver's amendment package has no effect across the city line. Designing to Denver requirements and submitting in Aurora is one of the most common avoidable corrections in the east metro.
What does the airport overlay near Denver International require?
Parcels within the overlay carry requirements that reach building height, exterior lighting, and in some cases use, all tied to proximity to airport operations. Those limits need to appear on the site plan and elevations early, because a height or lighting constraint discovered after the massing is set forces a redesign. Construction crane height during the build can also require attention.
How does expansive bentonite clay affect Aurora foundations?
Expansive clay swells when it takes on moisture and can lift slabs and interior partitions, so the geotechnical report determines the foundation type rather than office standard practice. That commonly means drilled piers with void form beneath grade beams and a structural floor instead of a conventional slab on grade. Pier schedules missing void form and slabs detailed without separation from partitions are frequent structural corrections.
What should an Anschutz Medical Campus project plan for in review?
Healthcare and research work at Fitzsimons carries institutional life-safety compartmentation, medical gas, essential electrical systems, laboratory containment and exhaust discharge, and vibration criteria for sensitive equipment, which makes the structural, mechanical, and electrical reviews interdependent. Phased work inside occupied facilities adds infection control requirements. Expect substantive review across disciplines rather than a single-track building review.
How long does Aurora plan review take?
Standard commercial review generally runs 3 to 8 weeks through Planning and Development Services, with building, structural, mechanical, plumbing, and fire reviewers working the set and site, drainage, and zoning handled alongside. Resolve airport and Buckley compatibility overlay status before the technical set is finished, since those determinations change the building rather than the drawings.
How does Helonic help on an Aurora project?
Helonic compares the architectural set against the structural and MEP sets and screens all of it against the 2021 IBC with Aurora amendments, reporting overlay conflicts on height and lighting, expansive soil foundation problems, altitude-corrected equipment gaps, healthcare and laboratory systems issues, and cross-discipline clashes, each tied to a sheet and section. Helonic is a screening tool. The licensed Engineer of Record retains design responsibility, and Aurora Planning and Development Services retains approval authority.
