Tips
- Lake Havasu City's published plan-review timeframes classify most stand-alone mechanical/HVAC permit work under the 'Miscellaneous' category, listed at 10 business days, consistent with Arizona's A.R.S. § 9-835 municipal time-frames requirement.
- A like-for-like HVAC unit replacement (no increase in size, capacity, location, or ampacity) is exempt from permitting entirely under the City's IRC amendment — confirm your replacement doesn't trip any of those thresholds before assuming a permit is required.
- Unlike some neighboring Arizona cities, Lake Havasu City's adopted code amendments do not include a mandatory residential-air-conditioning provision — the City deleted rather than added such a requirement (IRC R325.3 is amended to delete the entire section).
