Cave Creek Adopted Building Codes: The 2024 I-Codes That Apply to Your Build

Your home in the Town of Cave Creek is checked against a stack of national model codes that the Town Council voted to adopt by reference, then edited for local desert conditions. Cave Creek runs newer editions than the unincorporated county next door, so the exact rules differ depending on which side of the town line your lot sits. This page lists the codes Cave Creek actually enforces today, when they took effect, and the resolution that adopted them.

Which codes Cave Creek enforces

Cave Creek adopted the 2024 family of International Codes (often called I-codes) for most construction, with the 2023 electrical code and a few 2025-edition codes layered in. The editions changed on January 1, 2026. Here is the current list the Town's Building and Fire Code Compliance Division enforces:

• 2024 International Residential Code (IRC): one- and two-family homes and townhouses. This is the main code for a custom house.
• 2024 International Building Code (IBC): larger and commercial structures.
• 2024 International Mechanical Code (IMC): heating, cooling, and ventilation.
• 2024 International Fuel Gas Code (IFGC): gas piping and gas appliances.
• 2024 International Energy Conservation Code (IECC): insulation, windows, and HVAC efficiency for new commercial work.
• 2023 National Electrical Code (NEC): all wiring and electrical work.
• 2025 International Plumbing Code (IPC): water supply, drains, and fixtures.
• 2025 International Fire Code (IFC): fire and life-safety provisions.
• 2025 International Existing Building Code (IEBC): work on existing structures.
• 2024 International Pool and Spa Code (ISPSC): pools and spas.

One wrinkle is worth knowing. For homes, Cave Creek keeps the 2018 residential energy code rather than the 2024 energy code. So a single-family build follows the older, lighter energy path. The IRC is the code a single-family builder lives in day to day. The Town of Cave Creek is the authority having jurisdiction (AHJ) that adopts, amends, and enforces these codes, so its Building Official, not the county and not the state, has the final word inside town limits.

What the Town says

The codified ordinance states the adoption plainly. Chapter 151 of the Town Code opens its building section with the effective date and the adopting resolution:

Effective January 1, 2026, there is herewith adopted, by reference, The International Building Code, 2024 Edition, as published by the International Code Council, adopted as a public record by Resolution No. R2025-01 of the Mayor and Council of the Town of Cave Creek.

Each code in the stack carries its own section in Chapter 151 (Building at 151.01, Residential at 151.02, Mechanical at 151.03, Plumbing at 151.04, Electrical at 151.05, Fire at 151.06), and each section then lists the Town's local amendments to that code. So the rule you build to is the published edition as changed by Cave Creek's amendments for that code. The Town's older codes came in under Resolution R2022-03 in 2022; the current 2024-cycle set replaced them on the January 1, 2026 effective date.

When this comes into play

The edition controls real decisions from day one of design:

• Your framing, bracing, and foundation details follow the 2024 IRC as amended. A plan copied from an older 2018 or 2021 set may carry details the current code no longer matches, and it can get bounced in review.
• Outlet spacing, arc-fault and ground-fault protection, and panel sizing follow the 2023 NEC. An electrician working from a 2017 or 2020 code book may miss newer required protections.
• Residential energy compliance still runs on the 2018 energy code, not the 2024 edition. That keeps insulation and duct paperwork lighter than a city like Scottsdale requires, but you still have to meet the 2018 numbers.

Here is a real example. Say you submit a 3,000 square foot custom home plan in Cave Creek in early 2026. The plan reviewer checks your framing against the 2024 IRC. Your wiring is checked against the 2023 NEC. Your gas piping is checked against the 2024 IFGC. Your home energy sheet is checked against the 2018 residential energy code. If your designer reused a set drawn to Maricopa County's 2018 codes, several editions will not line up. The plan can then come back with corrections before a permit issues. A permit application started under the prior 2021 code cycle is reviewed case by case.

What this means for you

Hand your designer, structural engineer, and trades one clear instruction. Build to Cave Creek's 2024 I-codes and the 2023 NEC, with the Town's amendments applied, and use the 2018 residential energy code for a house. That single sentence prevents the most common and expensive plan-review correction, which is a sheet drawn to the wrong edition or to a neighboring jurisdiction's code. Cave Creek sits ahead of the surrounding unincorporated county (still on the 2018 codes and 2017 NEC), so a set drawn for a rural county lot is not automatically right for a town lot, and the reverse is also true.

This entry is the anchor for the rest of the Cave Creek building-codes module. From here, see Cave Creek Residential Building Permit Requirements for how these codes get checked during plan review and what you file to get a permit. If your lot is on septic or a private well, the water and wastewater side follows the county, covered in Maricopa County Septic and Well Requirements for a New Home .
