Building permits in unincorporated Cochise County are issued by the Building Safety Division of Development Services under the Cochise County Building Safety Code, from 1415 Melody Lane, Building F, Bisbee, AZ 85603 (520-432-9300, Monday to Friday 8am to 5pm). The county moved from the 2015 codes to the 2024 codes for applications filed from 1 September 2026, and it has adopted the tiny houses appendix.
This guide covers what requires a permit in unincorporated Cochise County, the value threshold that triggers one, the tiny homes appendix the county has adopted, the owner-builder route and its five-year limit, why wastewater goes to a different department, and the groundwater management area now covering part of the county.
This guide covers unincorporated Cochise County. Sierra Vista, Douglas, Bisbee, Willcox and Benson are separate, as is Fort Huachuca.
The Owner-Builder Amendment can only be used once every five years, per person. This is the Owner-Builder Amendment, a rural option for owner-builders on parcels zoned for one dwelling per four acres or larger, under which the county either reviews plans and makes only limited inspections or does no plan review and no building inspections at all (no certificate of occupancy is then issued). Cochise County limits it to once in every five years across all properties within the unincorporated county owned by that individual owner-builder — measured against the person, not the parcel. The limitation does not apply to non-habitable accessory structures or additions on the same property. An ordinary owner-builder permit, with full review and inspections, carries no such limit.
What requires a permit in Cochise County?
The Cochise County Building Safety Division helps residents, property owners, contractors and businesses complete construction projects in compliance with the Cochise County Building Safety Code. Staff review building plans, issue permits, and conduct inspections for residential and commercial construction in the unincorporated county.
The permit trigger is a value, and it is low. The county states that under state law any new structure or renovation with a value of $1,000 or more requires a permit. Certain minor residential home repairs and uses are exempt, but commercial projects are not included in those exemptions — so the exemption list is residential only. And exempt projects must still comply with county regulations and applicable state laws; exemption from the permit is not exemption from the rules.
The county has adopted the 2024 codes: the 2024 International Building, Residential, Existing Building, Mechanical, Fire, Fuel Gas, Plumbing and Swimming Pool and Spa Codes, the 2023 National Electrical Code and the 2012 International Energy Conservation Code, with local amendments (Resolution 26-23). They apply to permit applications submitted on or after 1 September 2026; applications submitted before that date are still reviewed under the 2015 codes. A design drawn to an older edition needs checking before it is filed.
The county has also adopted the tiny houses appendix — Appendix BB of the 2024 International Residential Code, which replaced the Appendix Q from the 2018 code it had adopted earlier — and publishes both the requirements and an informational flyer.

Cochise County building department: who handles permitting
Getting started here is refreshingly concrete. The county asks you to gather your parcel number, property address and a description of the proposed work, check the interactive zoning map, determine whether the project requires a building permit, and review the residential or commercial plan requirements before submitting. It also asks that you contact Building Safety staff before applying if you are unsure what is required — an invitation worth taking on anything marginal.

All wastewater systems are reviewed and permitted by the Cochise County Health Department's Environmental Health Division, which publishes alternative wastewater system requirements and a list of acceptable toilet brands. There is a trap attached: the county warns that you will still be required to install a small septic system even with an alternative system, because kitchen drain water is not considered grey water in Arizona. Anyone planning a grey-water-only arrangement needs to know that before designing.
Water is a live regulatory question in this county. The Douglas Groundwater Basin Active Management Area was established in December 2022, and active management areas are subject to statutory and administrative regulation of groundwater withdrawal and use by the state water agency. On a parcel relying on groundwater within that basin, the water position is a project constraint rather than a utility detail.

Cochise County moved to the 2024 codes in September 2026, and it has adopted tiny houses too. Applications filed from 1 September 2026 are reviewed under the 2024 International Building, Residential, Existing Building, Mechanical, Fire, Fuel Gas, Plumbing and Swimming Pool and Spa Codes, the 2023 National Electrical Code and the 2012 International Energy Conservation Code, with local amendments, including Appendix BB on tiny houses; earlier applications stay on the 2015 codes. The lesson is the Arizona lesson in miniature: there is no statewide code, and a jurisdiction’s position is a set of specific choices rather than a single edition number.
Cochise County permits the unincorporated county only. Sierra Vista, Douglas, Bisbee, Willcox, Benson, Tombstone and Huachuca City each run their own arrangements. The county also contains Fort Huachuca, a military installation on federal land outside county building jurisdiction, and it runs to the international border, where federal activity is extensive. Confirm the parcel's status before assuming the county is the authority.
In 2025, building permits issued in unincorporated Cochise County authorized 299 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.
Cochise County permits: record types and what each covers
The record catalog here is compact, but two entries are distinctive: the tiny home under the adopted appendix, and the owner-builder permit with its five-year limit.

| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New construction | New dwellings, additions, and accessory structures above the local size threshold | Plan review against the jurisdiction's adopted residential code and local amendments, plus zoning and setbacks | Valuation-based |
| Addition | Added conditioned or unconditioned space attached to an existing dwelling | Structural and energy review where the jurisdiction has adopted an energy code; most Arizona homes are in hot, dry climate zones, so envelope and equipment sizing draw attention | Valuation-based |
| Renovation / alteration | Structural changes, layout changes, or added plumbing, mechanical, or electrical | Plan review scaled to scope; a change that alters egress, structure, or a system is reviewed even where the footprint does not move | Valuation-based |
| Reroof | Roof covering replacement, recover, and structural deck repair | Deck and dry-in inspection; plan review rarely required, but a change of assembly type can trigger a structural check | Valuation or squares |
| Solar photovoltaic | Rooftop or ground-mount arrays, with or without battery storage | Single local review covering both the structural attachment and the electrical scope; there is no separate state electrical record in Arizona | Flat or system-size based |
| Battery energy storage | Wall or floor-mounted storage added to a dwelling | Electrical review plus fire separation, ventilation, and location check | Flat or per-permit minimum |
| Electrical | Service changes, panel upgrades, new circuits, EV chargers, meter sets, and rewiring | Local trade review and local inspection against the National Electrical Code edition the jurisdiction has adopted | Per-permit or per-device |

Solar in unincorporated Cochise County is permitted and inspected by Building Safety. The edition question depends on the filing date: applications from 1 September 2026 are reviewed under the 2023 National Electrical Code with the 2024 building codes, earlier ones under the previous set. Confirm which applies before finalising the design.
Roofing permits in Cochise
Reroofing is permitted work where the project value reaches the county's threshold, which is low enough that most roofing jobs are captured. The exemptions the county publishes cover certain minor residential repairs only and expressly do not extend to commercial projects. Cochise County sits at considerably higher elevation than the low desert, so roofing here contends with real seasonal weather rather than heat alone.
Arizona solar and roofing work is permitted and inspected locally, against the code edition each jurisdiction has adopted; utilities run interconnection on their own timeline. Arizona rules
Cochise County permit cost
Permit fees are assessed under the county's adopted fee provisions, with building fees driven by valuation and plan review assessed alongside. The threshold matters as much as the rate here: because a permit is required at a relatively low project value, small jobs that would sit below the radar elsewhere are inside the system in Cochise County.
Wastewater is a separate cost centre with a separate department. All wastewater systems are reviewed and permitted by the Health Department's Environmental Health Division, and the requirement to install a septic system even where an alternative system is used — because kitchen drain water is not grey water in Arizona — is a design and cost consequence worth establishing early.
| Fee component | How it works |
|---|---|
| Building permit fee | Under the county's adopted fee provisions |
| Plan review | Assessed alongside the building permit |
| Permit threshold | Applies from a project value of $1,000 |
| Wastewater permit | Health Department, Environmental Health Division, assessed separately |
| Septic requirement | Applies even with an alternative system, given the grey water rule |
| Trade permits | Electrical, plumbing, gas and mechanical charged per discipline |
| Re-inspection | Charged where an inspection has to be repeated |

Cochise County trade permits
The trades are permitted and inspected by Building Safety under the Cochise County Building Safety Code. Arizona has no state electrical permit — but wastewater sits with a different county department entirely.
Electrical permits
Required for service work, panel changes, photovoltaic systems, electric vehicle chargers and most wiring alterations. The county enforces the 2023 National Electrical Code with local amendments on applications filed from 1 September 2026.
Plumbing permits
Required for new piping, repipes, fixtures and water heaters — but the wastewater system itself goes to the Health Department's Environmental Health Division rather than Building Safety. Note that kitchen drain water is not treated as grey water in Arizona, so a small septic system is still required alongside an alternative system.
Mechanical permits
Required for heating, ventilation and air-conditioning installations, changeouts, ductwork and refrigeration. Cochise County sits at considerably higher elevation than the low desert, so heating load is a more meaningful part of the design here than a Phoenix assumption would suggest.
Telecommunications facilities
Cell towers and other telecommunications facilities are subject to county review, require building permit review and approval, and are evaluated for zoning compliance. Federal law constrains what a local authority may consider on some aspects of these facilities, so establish the scope of county review early.

Cochise County permit application: how to apply step by step
Here is how to get a building permit in Cochise County, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Sierra Vista, Douglas, Bisbee, Willcox, Benson, Tombstone and Huachuca City run their own arrangements, and Fort Huachuca is federal land outside county jurisdiction.
Parcel number, property address and a description of the proposed work, then check the interactive zoning map and determine whether a permit is required. Contact Building Safety before applying if you are unsure.
Any new structure or renovation valued at $1,000 or more requires a permit under the state law the county applies. The exemptions cover certain minor residential repairs only — commercial work is not included.
All wastewater systems are reviewed and permitted by the Health Department's Environmental Health Division, and a septic system is required even with an alternative system because kitchen drain water is not grey water in Arizona.
Part of the county now sits within an established groundwater basin active management area, which brings statutory and administrative regulation of groundwater withdrawal and use. On a well-supplied parcel, establish this before design.
Review the residential or commercial plan requirements before submitting, and use the county's online record search to check the permit and violation history of the property.
Inspections in Cochise County
Building Safety staff review plans, issue permits and conduct inspections for residential and commercial construction, with the stated purpose of safeguarding public health, safety and general welfare through enforcement of building and zoning codes. Zoning is enforced alongside building rather than separately.
The county's online records search is genuinely useful during a project as well as before one. Entering an address or parcel number without dashes returns active and historical records including building permits, planning applications, septic permits, health licences and code violations. On a rural property with a long history, that is the fastest way to understand what has already happened on the land.
The Owner-Builder Amendment limit deserves managing across a portfolio rather than a project. Because the amendment is limited to once every five years for dwellings across all properties in the unincorporated county owned by that individual, using it on a minor build forecloses it on a major one for the same period. The limitation does not apply to non-habitable accessory structures or additions on the same property. Lenders and insurers may ask for more than an amendment permit provides, since the county does not certify full code compliance under it.
Close-out follows the ordinary sequence to the occupancy certificate once every required inspection has passed. Because wastewater sits with the Health Department, expect that approval to be a separate track that has to be clear as well — identify it at the start rather than at final.

When do I need a permit in Cochise County?
The county states that under state law any new structure or renovation with a value of $1,000 or more requires a permit. Certain minor residential home repairs and uses are exempt, but commercial projects are not included in those exemptions, and exempt projects must still comply with county regulations and applicable state laws.
Which building code does the county use?
For applications submitted from 1 September 2026, the 2024 International Building, Residential, Existing Building, Mechanical, Fire, Fuel Gas, Plumbing and Swimming Pool and Spa Codes, the 2023 National Electrical Code and the 2012 International Energy Conservation Code, with local amendments (Resolution 26-23), including Appendix BB on tiny houses. Applications submitted before that date are reviewed under the 2015 codes.
Does the county allow tiny homes?
Yes. Cochise County has adopted Appendix BB (Tiny Houses) of the 2024 International Residential Code, replacing the 2018 code’s Appendix Q it used before, and publishes both the requirements and an informational flyer.
How often can I use the owner-builder option?
It depends which route. An ordinary owner-builder permit has no such limit: you sign an owner-builder affidavit that the home is for your own occupancy and not for sale or rent within a year (A.R.S. 32-1121), and the full review and inspections apply. The five-year limit belongs to the Owner-Builder Amendment, a rural option for owner-builders on parcels zoned for one dwelling per four acres or larger, under which the county either reviews plans and makes only limited inspections or does no plan review and no building inspections at all (no certificate of occupancy is then issued). That amendment can be used once in every five years for dwellings on all properties within the unincorporated county owned by that individual; the limit does not apply to non-habitable accessory structures or additions on the same property.
Who permits my septic system?
The Cochise County Health Department's Environmental Health Division, not Building Safety. All wastewater systems are reviewed and permitted there, and the department publishes alternative wastewater system requirements and a list of acceptable toilet brands.
Can I use a grey water system instead of a septic system?
Not entirely. The county warns that you will still be required to install a small septic system, because kitchen drain water is not considered grey water in the State of Arizona. Anyone planning a grey-water-only arrangement needs to know that at the design stage.
What is the Douglas active management area?
The Douglas Groundwater Basin Active Management Area was officially established in December 2022. Active management areas are subject to statutory and administrative regulation of groundwater withdrawal and use by the state water agency. On a parcel relying on groundwater in that basin, water is a project constraint.
Do cell towers need a permit?
Yes. Cell towers and other telecommunications facilities are subject to county review, require building permit review and approval, and are evaluated for zoning compliance. Federal law constrains what a local authority may consider on certain aspects, so establish the scope of county review early.
How do I check a property's history?
Use the county's online record search. Enter the address or parcel number without dashes to view active and historical records including building permits, planning applications, septic permits, health licences and code violations. On rural land with a long history that is the fastest orientation available.
What should I have ready before I apply?
The county asks for the parcel number, the property address and a description of the proposed work. It also directs you to the interactive zoning map, to determine whether a permit is required, and to review the residential or commercial plan requirements before submitting — and to contact staff first if you are unsure.
Do the state accessory dwelling unit rules apply here?
Yes, since 2026. A 2025 law (A.R.S. 11-810.01) requires every Arizona county to allow at least one attached and one detached accessory dwelling unit as a permitted use on any lot where a single-family dwelling is allowed, with county regulations due by 1 January 2026. It does not apply on tribal land or near military and some public airports — relevant around Fort Huachuca. The county publishes its own accessory dwelling unit page; check it before you design.
Does the county permit on Fort Huachuca?
No. Fort Huachuca is a military installation on federal land, outside county building jurisdiction. The county also runs to the international border where federal activity is extensive. Confirm the land status of the parcel before assuming the county is the authority.
Simplify Cochise County permitting with Alliance Permitting
Cochise County combines a recent move to the 2024 codes with a tiny houses appendix, a low permit threshold, an Owner-Builder Amendment with a strict five-year limit and wastewater handled by a different department. None of that is difficult once it is known. Alliance Permitting prepares, files and tracks Cochise County permits through issuance.
Trusted by leading builders, developers, and national contractors — 21+ years of filing in the jurisdictions we write about.
Contractors and builders choose Alliance for Cochise because the work is done by people who have stood at the counter:
- We design to the county's actual adopted edition rather than a current national one.
- We manage the owner-builder five-year allowance across a portfolio, not project by project.
- We open the wastewater track with the Health Department at the start, not at final inspection.
- We check the groundwater management position on any parcel relying on a well.
Alliance Permitting is a permit documentation and expediting service in Arizona. We are not a law firm and do not provide legal advice, and we are not the permitting authority.
