Frisco adopted the 2024 International Building Code (IBC) with local amendments effective March 1, 2026. If your design documents were prepared under the 2021 or 2018 IBC, your team needs to revisit them before submittal — submitting under the wrong code cycle is one of the most avoidable causes of permit delay in DFW.
What the 2024 IBC actually changed
The 2024 IBC is a significant update cycle. The changes that matter most for commercial TI and ground-up projects in Frisco fall into three categories:
- Energy code updates: The 2024 IBC references updated ASHRAE 90.1 requirements, affecting mechanical system specifications, envelope performance, and lighting controls. HVAC designs prepared under the 2021 cycle may need to be re-engineered to meet updated efficiency thresholds.
- Accessibility: The 2024 edition incorporates expanded accessibility provisions aligned with current ADA guidance. This affects accessible route design, restroom layouts, and reach-range requirements — particularly relevant for medical and retail projects.
- Life safety and egress: Updated egress path requirements and sprinkler thresholds apply in several occupancy types. Confirm with your architect which occupancy classifications trigger changes in your specific project.
The 2024 IBC is rolling in across DFW on different schedules. As of May 2026, Frisco has adopted it — always confirm the current code version with the specific city before your architect finalizes construction documents.
DFW permitting timelines right now
Texas is one of the fastest permitting environments in the country. But fast is relative, and people consistently underestimate the permit phase when planning total project schedules.
3–8 weeks
Typical commercial permit review time, DFW suburban jurisdictions (Frisco, Allen, Plano, McKinney, Prosper, Richardson), directional, May 2026 [permitting timeline data, 2026]
6–12 weeks

The 3–8 week range for DFW suburbs is achievable — but it assumes a complete, code-compliant first submittal. High growth volume in Frisco and surrounding cities means review queues fluctuate. Submitting in lower-volume months (roughly December through February) tends to be faster. A resubmittal cycle — triggered by incomplete drawings or code deficiencies — can add 2–4 weeks per round.
Most common planning mistake: counting the permit timeline as zero. 'We'll start construction in June' ignores 4–6 weeks of permit review plus 2–4 weeks of upstream design coordination — the building phase is usually the shortest part.
How Pereff compresses the timeline
We manage the permitting process in-house for every project. Four practices make a consistent difference:
- Pre-application meeting with the building department: We request a meeting with the city plan reviewer before formal submittal to surface any concerns about occupancy classification, change-of-use triggers, or code interpretation. A 45-minute meeting can eliminate a 3-week resubmittal cycle.
- Complete, code-compliant first submittals: We coordinate architect, MEP engineer, and structural engineer drawings before we touch the submit button. Incomplete submissions are the number-one cause of permit delays in every jurisdiction.
- Early/foundation permits where available: On ground-up projects where the jurisdiction allows it, we pursue a foundation-only permit so sitework and footings can start while the full building review finishes. This can compress the critical path by 3–5 weeks.
- Long-lead item procurement runs parallel to permitting: Rooftop units, switchgear, specialty MEP equipment, and custom-fabricated items are ordered as soon as design is sufficiently advanced — we don't wait for the permit to land.
The design-build model helps here. Because our architecture and construction teams are the same team, design decisions get made with construction and permitting in mind from day one. A design-bid-build project can lose weeks simply because the architect's drawings weren't designed to pass permit review efficiently.
