Building permits in unincorporated Pima County are issued by the Development Services Department, working alongside Planning, Floodplain Management and the Regional Flood Control District. Pima is one of the best-documented permitting authorities in Arizona and one of the few offering remote inspections.
This guide covers what requires a permit in unincorporated Pima County, the Permit Gateway and its electronic-only submittal rule, the twenty twenty-four codes now in force, the four components that make up a permit fee, the P2F and P2C condition system, and the rule that makes a passed final inspection the certificate on a house.
This guide covers unincorporated Pima County. Tucson, Marana, Oro Valley, Sahuarita, South Tucson and tribal land are separate.
On a single-family dwelling, the passed final inspection is the Certificate of Occupancy. Under Pima County Code, final inspection approval of single family dwellings constitutes the certificate — there is no separate document to chase afterwards. That raises the stakes on the final itself, because the conditions the county labels prior to final inspection and prior to certificate of occupancy both have to be satisfied, and both are listed on the permit.
What requires a permit in Pima County?
The Pima County Development Services Department permits and inspects construction in the unincorporated county, working alongside Planning, Floodplain Management and the Regional Flood Control District. Properties inside Tucson, Marana, Oro Valley, Sahuarita or South Tucson are permitted by those municipalities instead.
The county is on the twenty twenty-four building codes together with the twenty twenty-three National Electrical Code, effective from the first of January twenty twenty-six. That puts Pima County at the front of the Arizona field rather than the middle, and ahead of several counties still on the twenty eighteen or earlier editions. The county notes that the code body provides access to the unamended codes online; the county's own amendments sit alongside them.
Submittal is electronic. Building permits and site development instruments require electronic submittal through the Permit Gateway, an account is needed to apply, and the county is explicit that project files may not be delivered to its offices on thumb drive or disc. Documents are converted to portable document format and named per the posted criteria, and where secured files are sent the county asks for a security setting that still allows it to apply an approval watermark.
Development Services also runs the Code Compliance programme, whose inspectors investigate reported complaints and assist owners in correcting violations and maintaining compliance with county zoning and building codes. The Permit Gateway doubles as the public record: it provides access to complaints, violations, applications, permits, project records, associated inspections and payments, searchable by address.

Pima County building department: who handles permitting
Development Services sits on the first floor of the Public Works Building on North Stone Avenue, with lobby hours in the morning and early afternoon on weekdays. Building and Site Development has its own direct line, and the county has moved specific workflows off email — septic submittals are no longer accepted through the building safety administration inbox, and questions, revisions, corrections and inspections route to their own addresses.
The inspection portal offers remote inspections alongside field visits. The county's updated building inspection portal lets you schedule either a traditional field inspection or a remote inspection from one place, with a free account required. That capability is rare in Arizona and genuinely valuable in a county this large, where an inspector's travel time to a remote parcel can dominate the working day. Separately, a public works inspection tracking tool lets you search by full permit number to see scheduled inspections and inspection comments.
Two published guides mark Pima County out as a place where people build in genuinely rural conditions. The county publishes a summary of its rules and regulations for off-grid living in the unincorporated county, and a defensible spaces guide on preventing fire spreading between structures. Neither is boilerplate: they answer questions that come up constantly on desert parcels and rarely come up in a city.

Pima County will do your inspection remotely. The county's updated inspection portal lets you schedule a traditional field inspection or a remote inspection in the same place, with a free account. In a county that stretches from the Tucson suburbs to the far desert, that is the difference between a same-week inspection and a wait for an inspector's route to reach you. Set the account up at permit issuance so the option is available when you need it rather than when you discover it.
Pima County permits the unincorporated county only. Tucson, Marana, Oro Valley, Sahuarita and South Tucson each run their own building departments with their own adopted editions and portals, and Tucson's code position in particular differs from the county's. The county also contains substantial tribal land, which is a sovereign jurisdiction outside county building authority. Confirm the parcel's status before assembling a submittal.
Pima County permits: record types and what each covers
Record types in Pima County are organised within modules in the land permitting system, which is worth knowing because it explains why the portal asks what kind of record you want before it asks anything else.
Residential permit types
| 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; most of Arizona sits in a hot-dry climate zone, 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 |
| Plumbing | New piping, repipes, fixtures, gas piping, and water heater replacement | Local trade review; performed by a contractor holding the matching Registrar of Contractors specialty classification | Per-permit minimum or per-fixture |
| Mechanical / HVAC | Changeouts, new ductwork, and refrigeration | Local trade review; changeout volume is heavy in Arizona given summer design temperatures | Per-permit minimum or per-unit |
| Patio cover and shade structure | Attached and detached covers, ramadas, and carports | Structural review for wind uplift and attachment, plus zoning for setbacks and lot coverage | Valuation or flat |
| Swimming pool | In-ground and above-ground pools and spas | Barrier, bonding, and electrical review; Arizona sets a statewide minimum pool barrier standard that applies on top of local rules | Valuation or flat |
| Manufactured home set-up | Placing or re-siting a manufactured or modular home | State plan approval through the Arizona Department of Housing, with local zoning, floodplain, foundation, and utility connection review | Flat or per-unit |
| Demolition | Full or partial demolition of a dwelling or accessory structure | Utility disconnect confirmation, dust control where earthmoving is involved, and site restoration check | Flat |
| Remote inspection | Any inspection where a field visit is impractical or slow to schedule | Booked through the inspection portal in place of a field visit | Free account required to schedule |
| Off-grid residential build | Parcels with no utility connection | Governed by the county's published off-grid living rules | Assessed with the building permit |
Commercial permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New commercial construction | Ground-up commercial, industrial, and institutional buildings | Concurrent review against the jurisdiction's adopted building code and amendments, plus fire and zoning | Valuation-based |
| Tenant improvement / upfit | Interior fit-out of an existing tenant space | Building, trade, and life-safety review; accessibility attaches on change of use | Valuation-based |
| Change of occupancy | Converting a building or space to a different use group | Occupancy classification, egress, and accessibility review | Valuation or flat |
| Commercial electrical | Service, distribution, and branch circuit work | Local trade review and local inspection; Arizona has no central state electrical permit for either residential or commercial work | Per-permit or valuation |
| Commercial plumbing | Process piping, fixtures, backflow, and grease waste | Local trade review; backflow and grease interceptor sign-off where applicable | Per-fixture or valuation |
| Commercial mechanical | Rooftop units, kitchen exhaust and hood systems, and refrigeration | Local trade review; hood and suppression systems draw fire review alongside mechanical | Per-unit or valuation |
| Commercial reroof | Roof covering replacement on a commercial structure | Deck, dry-in, and attachment inspection | Valuation or squares |
| Signage | Wall, ground, and illuminated signs | Zoning review for size and placement, plus electrical where illuminated | Flat or per-sign |
| Grading and drainage | Clearing, grading, and site work that alters drainage | Civil review of grading and drainage, separate from the building permit; monsoon-season flows drive the design | Acreage or valuation |
| Dust control permit | Earthmoving, trenching, and construction dust on a qualifying site | County air quality department, not the building department; required in the fine-particulate nonattainment areas | County air quality fee schedule |
| Commercial demolition | Full or partial demolition of a commercial structure | Utility disconnect, asbestos notification, dust control, and site restoration | Flat or valuation |
| Site development instrument | Commercial site work alongside the building record | Also requires electronic submittal through the Permit Gateway | Site development component of the overall fee |
| Permit activity extension or reinstatement | Projects whose permit activity has lapsed or is about to | Filed on the county's published form | Per the county's adopted fee schedule |

Solar permits in Pima
Solar is reviewed on two tracks in Arizona, but unlike some neighbouring states both tracks belong to the same government. The structural side — attachment detail, rail spacing, and whether the existing framing carries the added dead load — and the electrical side — conductors, overcurrent protection, rapid shutdown, labelling, and the service or supply-side connection — are both permitted and inspected by the local Authority Having Jurisdiction. There is no state electrical record to buy alongside the local one, and no state inspector to book.
Solar in unincorporated Pima County is permitted and inspected by the county under the twenty twenty-four codes and the twenty twenty-three National Electrical Code, in force since the start of twenty twenty-six. That is a newer electrical edition than several neighbouring authorities enforce, so confirm before importing a design. The remote inspection option is particularly valuable on solar in a county this large, where a straightforward array on a distant parcel would otherwise wait for an inspector's route. Interconnection stays with the serving utility.
What varies instead is the code edition. Because each Arizona city, town and county adopts its own editions on its own timetable, the National Electrical Code edition your array is judged against in one jurisdiction may not be the one enforced a few miles away. The Office of the State Fire Marshal sets a minimum electrical standard for the state, but the edition actually enforced is the local one. Confirm it with the jurisdiction before the design is finalised rather than after a correction notice.
Interconnection runs on a third clock and is not something the building department controls. Arizona properties are served by utilities including Arizona Public Service, Salt River Project, Tucson Electric Power and UniSource, alongside municipal utilities and irrigation districts, and each sets its own application, meter and witness-test sequence. Permission to operate follows the utility's process on the utility's schedule, so plan for the tracks to finish at different times.
Roofing permits in Pima
A roof covering replacement needs a permit in most Arizona jurisdictions, and the assumption that a like-for-like replacement is exempt travels badly here. The permit is usually quick, but the inspection that matters happens before the covering goes on rather than after.
Arizona operates no statewide product-approval database, so there is no approval number to search for or cite on the application. The assembly has to comply with the edition of the code the jurisdiction has adopted and with the manufacturer's listed installation instructions, and that pairing is what the inspector checks — which makes the manufacturer's instructions a document worth having on site.
Reroofing follows the ordinary sequence with the deck and dry-in inspected before the covering goes on. The Pima County detail worth carrying is the close-out rule: on a single-family dwelling the passed final inspection is itself the certificate of occupancy, so the conditions listed on the permit as prior to final have to be genuinely clear. Southern Arizona roofing is designed against heat, ultraviolet exposure and monsoon wind and rain rather than snow, though the county's elevation range is wider than Tucson alone suggests.
Two Arizona-specific pressures shape the work. Sustained summer heat and ultraviolet exposure age a covering faster than the same assembly would age in a milder climate, and monsoon-season wind and driven rain test the fastening and the flashing details rather than the field of the roof. Sequencing is where reroofs go wrong regardless: the deck and dry-in condition has to be visible when the inspector arrives, so covering it first means opening it back up.
Pima County permit cost
Pima County is unusually transparent about what a building permit fee actually consists of. The county states that building permit fees are comprised of site development, building permit, wastewater sewer connection and transportation right-of-way impact fees, and it publishes estimate calculators for them. That breakdown is more useful than a single valuation figure, because it shows which components a given project can and cannot avoid.
The county also publishes operational review turn-around times for development instruments, and a request form for permit activity extension or reinstatement. Between the fee calculators and the published turn-around times, a Pima County project can be both priced and programmed from public documents before anything is filed.
| Fee component | How it works |
|---|---|
| Site development fee | One component of the overall building permit fee |
| Building permit fee | The core component, with published estimate calculators |
| Wastewater sewer connection fee | Calculated under the county's wastewater connection provisions |
| Transportation right-of-way impact fee | A further component of the total |
| Public water system plan review | Submittal fees for approval to construct |
| Extension or reinstatement | Requested on the county's published form |
| Published turn-around times | Operational review times for development instruments |

Pima County trade permits
The trades are permitted and inspected by the county under the twenty twenty-four codes and the twenty twenty-three National Electrical Code. Arizona has no state electrical permit, so nothing is filed with the state alongside.
Electrical permits
Required for service work, panel changes, photovoltaic systems, electric vehicle chargers and most wiring alterations. Pima County is on the twenty twenty-three National Electrical Code, a newer edition than several neighbouring authorities, so confirm the edition before importing a design from an adjoining jurisdiction.
Plumbing permits
Required for new piping, repipes, fixtures and water heaters. On rural parcels the plumbing scope connects to the on-site wastewater system, and septic submittals go to their own address rather than the general building inbox — a routing change worth noting if you have filed here before.
Mechanical permits
Required for heating, ventilation and air-conditioning installations, changeouts, ductwork and refrigeration. Southern Arizona's elevation range means heating load matters more here than in the low desert, and the county's energy testing resources are published alongside its permit resources.
Off-grid and alternative systems
Not a trade, but a real category in this county. Pima County publishes a summary of its rules and regulations for off-grid living in the unincorporated county, covering the questions that arise when a parcel has no utility connection. Read it before designing an off-grid build rather than discovering the requirements at review.
Pima County permit application: how to apply step by step
Here is how to get a building permit in Pima County, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Tucson, Marana, Oro Valley, Sahuarita and South Tucson permit their own work, and tribal land is a separate jurisdiction again. Settle this from the parcel first.
The county's twenty twenty-four building codes and the twenty twenty-three National Electrical Code have applied since the start of twenty twenty-six. Read the county amendments alongside the unamended codes.
Building permits and site development instruments require electronic submittal, an account is needed to apply, and files cannot be delivered on thumb drive or disc. Follow the posted file naming and security criteria.
Building permit fees here comprise site development, building permit, wastewater sewer connection and transportation right-of-way impact components, with published estimate calculators for each.
The permit lists the requirements that must be satisfied prior to final inspection and prior to issuance of a certificate of occupancy. Read them when the permit issues, not when you are trying to close out.
The inspection portal offers both a traditional field inspection and a remote inspection from one place. Create the free account early so the option is there when the schedule needs it.
Inspections in Pima County
Inspections are scheduled through the county's updated inspection portal, which offers a traditional field inspection or a remote inspection from the same place. A separate public works inspection tracking tool lets you search by full permit number to see scheduled inspections and read inspection comments, moving between the previous business day, today and the next.
Close-out depends on what you built. The county states that the permit lists requirements to be satisfied prior to final inspection and, separately, prior to issuance of a certificate of occupancy — two distinct sets of conditions. But for single-family dwellings, county code makes the final inspection approval itself constitute the certificate of occupancy, so there is no separate document to obtain afterwards.
Code Compliance runs alongside inspection rather than separately. Compliance inspectors investigate reported complaints and assist owners in correcting violations, and the Permit Gateway exposes complaints and violations alongside permits and inspections in the same searchable record. On a property with history, search the address before you buy or before you file.
Where the project also carried floodplain, septic or right-of-way scopes, expect those to need clearing alongside the building items. The Regional Flood Control District issues floodplain use permits in the unincorporated county, and the Floodplain Management Division publishes parcel-level floodplain information.

Frequently asked questions
Does Pima County permit my project?
Only if the parcel is in the unincorporated county. Tucson, Marana, Oro Valley, Sahuarita and South Tucson each permit their own work under their own adopted editions, and the county also contains substantial tribal land, which is a sovereign jurisdiction outside county building authority.
Which codes does Pima County enforce?
The twenty twenty-four building codes together with the twenty twenty-three National Electrical Code, effective from the first of January twenty twenty-six. That is ahead of several Arizona counties still on twenty eighteen or earlier editions. The county's own amendments apply alongside the unamended model codes.
Can I get a remote inspection?
Yes. The county's updated building inspection portal lets you schedule either a traditional field inspection or a remote inspection in one place, with a free account. In a county this large that can be the difference between a same-week inspection and waiting for an inspector's route to reach a remote parcel.
Do I get a separate Certificate of Occupancy?
It depends what you built. The permit lists conditions to be satisfied prior to final inspection and, separately, prior to issuance of a certificate of occupancy. But under Pima County Code, final inspection approval of single family dwellings constitutes the Certificate of Occupancy — so on a house there is no separate document to chase.
How do I submit plans?
Electronically, through the Permit Gateway, with an account. Building permits and site development instruments both require electronic submittal. Convert documents to portable document format and name consolidated files per the posted criteria, and note that project files may not be delivered to county offices on thumb drive or disc.
What makes up a Pima County permit fee?
Four components: site development, building permit, wastewater sewer connection, and transportation right-of-way impact fees. The county publishes estimate calculators for them, which makes a Pima County project pricable from public documents before anything is filed.
Is there guidance for building off-grid?
Yes, and it is unusual. The county publishes a summary of its rules and regulations for off-grid living in unincorporated Pima County, alongside a defensible spaces guide on preventing fire from spreading between structures. Both answer questions that arise constantly on desert parcels and rarely in a city.
Do the state accessory dwelling unit rules apply here?
No. Arizona's twenty twenty-four accessory dwelling unit statute sits in the state's cities and towns title and binds municipalities above a population threshold. It does not reach counties at all. Accessory dwelling units in unincorporated Pima County are governed by the county's own zoning code.
How do I check a property's permit history?
Search by address in the Permit Gateway. It provides access to complaints, violations, applications, permits, project records, associated inspections and payments. On a property with history, that search is worth running before you buy and before you file.
Who handles floodplain?
The Regional Flood Control District issues floodplain use permits in the unincorporated portions of the county, and the Floodplain Management Division provides up-to-date floodplain information for residents, including parcel-level information through the county's parcel information search.
Can I extend a permit?
The county publishes a Request for Permit Activity Extension or Reinstatement form. Use the published form rather than an informal request, and deal with it before the activity lapses rather than afterwards.
Where do septic submittals go?
Not to the general building safety administration inbox — the county has moved them. Questions, revisions, corrections and inspections route to their own addresses. If you have filed here before, check the current routing rather than reusing an old contact.
Simplify Pima County permitting with Alliance Permitting
Pima County is one of the best-documented permitting authorities in Arizona — published fee components, published turn-around times, published off-grid and defensible space guidance, and remote inspections. The work is in using it properly. Alliance Permitting prepares, files and tracks Pima 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 Pima because the work is done by people who have stood at the counter:
- We build electronic submittals to the county's file naming and security criteria on the first pass.
- We price from the four published fee components rather than a single valuation guess.
- We read the prior-to-final and prior-to-certificate conditions at issuance, not at close-out.
- We set up remote inspection access early, which on a far-flung parcel can save a week.
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.
