Work That Does NOT Require a Permit

• Agricultural structures: Structures used exclusively for agricultural purposes (barns, equipment storage, livestock shelters, granaries) on properties used for bona fide agricultural operations may qualify for exemption from the commercial building code under NMAC 14.5. These structures are still subject to basic safety requirements.

Important: Exempt from building permit does not mean exempt from other regulatory requirements. Agricultural exemption caution: Clients should not assume agricultural exemption applies without confirming with CID. Structures that will be used partly for residential purposes or that will be converted to residential use lose the agricultural exemption and are subject to full residential building code requirements. Confirm exemption eligibility with CID before commencing work.
