Building permits in Chandler are issued by the Development Services Department through its Building Safety function. Chandler offers several process shortcuts — self-certification, a free pre-technical review, walk-in plan review and duty representatives in every discipline — and the applicants who do badly here are generally the ones who use none of them.
This guide covers what requires a permit in Chandler, the 2024 codes adopted under Ordinance 5108 and the date they bind from, the self-certification route, the required pre-technical review, the representative-of-the-day system, the Unified Development Manual, and the distinction between completion and occupancy.
This guide covers work inside the Chandler city limits. The neighbouring East Valley cities and the county are separate.
A Certificate of Completion alone does not authorise occupancy. Chandler amended the adopted code specifically to say so. On a project where a completion document arrives before the occupancy certificate, that distinction is the difference between a finished building and a lawfully occupiable one — and occupying ahead of the certificate is an enforcement matter with consequences for financing and insurance.
What requires a permit in Chandler?
The City of Chandler Development Services Department issues building permits and conducts plan review and inspections inside the Chandler city limits through its Building Safety function. The department covers sound land use planning, design development standards and infrastructure alongside building safety, and it publishes its requirements through a single technical document rather than scattering them.
Chandler has amended and adopted the 2024 editions of the International Codes with the 2023 edition of the National Electrical Code, and all plans submitted for review on or after the first of July 2025 must be designed to comply. The adopting instrument is Ordinance 5108, which carries the city's amendments and is published in full. Plans submitted before that date were reviewed under the prior set. Any summary describing Chandler as being on the 2021 editions is out of date.
Ordinance 5108 is worth reading rather than skimming, because the amendments are substantive. Among other things it deletes the annual permit provision entirely and replaces it, amends the expiration provisions, and adds a clarification that a Certificate of Completion alone does not authorise occupancy of a building. That last one is a genuine trap on a project where a completion certificate arrives before the occupancy certificate.
The technical requirements live in the Unified Development Manual, which gives electronic access to more than 300 pages of municipal regulations, administrative procedures, technical standards and construction specifications, and is also where the application forms for permits, licences and other permissions are found. It is the single most useful document for anyone building here regularly.
Permit required
- New residential and commercial construction, additions and tenant improvements
- Structural and load-bearing alterations, relocation and demolition
- Change of occupancy under the adopted existing building code
- Re-roofing where the replacement increases the structural load
- Swimming pools and spas, with barrier compliance
- Solar photovoltaic systems and battery storage
- Electrical, plumbing, gas and mechanical work
- Fences and walls, which need zoning clearance regardless of height
Typically exempt
- Purely cosmetic finish work that alters no regulated system
- Certain like-for-like equipment replacements under the city's homeowner guidance
- Roof covering replacement that does not increase the structural load
- Routine maintenance that does not extend or reroute a system
Chandler building department: who handles permitting
Chandler runs a representative of the day system that is genuinely useful and under-used by people filing here for the first time. Calling the department connects you to duty representatives in Building Safety, Civil Engineering, Planning, Traffic Engineering and the Permit Counter, and the department publishes separate direct numbers for the Plan Reviewer of the Day for general building code questions and the Planner of the Day for zoning questions. Asking the right desk is considerably faster than a general enquiry.
Two process features change how a Chandler project should be planned. Pre-technical review is now required for any proposed subdivision, site plan development, new building or substantial building addition, and it is free of charge. It is a step rather than an option on those project types, so build it into the front of the programme. Separately, a walk-in plan review service runs Monday to Friday, 8 a.m. to 4:30 p.m., for residential and small commercial projects; the plan reviewer on duty decides whether a project qualifies.

Registered design professionals can self-certify in Chandler. The city allows a registered design professional to certify that a project complies with all applicable laws and codes, which changes the shape of the review for those who qualify. It is a genuine efficiency, and it is also a genuine transfer of responsibility — the certifying professional takes on the compliance obligation that the city's review would otherwise have tested. Confirm the current programme scope and eligibility with Building Safety before relying on it for a schedule.
Chandler is not Gilbert, Mesa, Tempe or unincorporated Maricopa County. The East Valley boundaries interleave along shared arterials, and the adopted editions differ between neighbours even where the cities touch. Chandler's July 2025 cut-over to the 2024 codes is its own, and a set that cleared review in a neighbouring city is not automatically compliant here. Settle jurisdiction from the parcel, then settle the edition from the city.
In 2025, building permits issued in Chandler authorized 719 new privately owned housing units, 167 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.
Chandler permits: record types and what each covers
Chandler's record catalog is best approached through the Unified Development Manual, which carries both the technical standards and the application forms for permits, licences and other permissions.

| 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 |
| 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; the local pool barrier rules apply, and Arizona’s state barrier law covers places with no local barrier ordinance | Valuation or flat |
| Manufactured home set-up | Placing or re-siting a manufactured or modular home | Installation permit and inspection through the Arizona Department of Housing’s Office of Manufactured Housing, or the local agency acting for it, with local zoning, setback, floodplain 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 |
| Zoning clearance for fences and walls | Any fence or wall, regardless of height | Cleared through the Planner of the Day before construction | Per the adopted fee schedule |

Get a free quote →Solar permits in Chandler
Solar in Chandler is permitted and inspected by the city under the 2024 codes and the 2023 National Electrical Code adopted by Ordinance 5108. Note the specific pairing: Chandler adopted the 2023 electrical edition rather than the 2024, a deliberate choice recorded in the ordinance, so do not assume the newest edition applies. Where a qualifying registered design professional is involved, the self-certification route may also be open, which can change the review path materially on a commercial array.
Roofing permits in Chandler
Chandler draws the reroofing line by structural load rather than by scope: the city's homeowner guidance has treated roof covering replacement as not requiring a permit where the replacement roof does not increase the structural load. That is the opposite of the rule in several other Arizona jurisdictions, where roof work is expressly permit-required, so do not carry an assumption across city lines in either direction. Where the replacement does add load, or where deck or structural repair is involved, it is permitted work. Confirm the current position before starting.
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
Chandler permit cost
Chandler assesses permit fees under the schedule adopted by the city, with the adopted code amended so that permit fees are set by the City rather than left to the model code's own schedule. Building fees are valuation-driven with plan review assessed alongside, and trade permits are charged per discipline.
Two things are worth budgeting that are not permit fees. The pre-technical review required on new buildings and substantial additions is free, but it is a programme item that has to happen before submittal. And requesting copies of a permit, a Certificate of Occupancy or building plans requires a Request for Public Records form rather than an informal ask — relevant on a renovation where the existing drawings are being sought.
| Fee component | How it works |
|---|---|
| Building permit fee | Set by the City under the adopted fee schedule |
| Plan review fee | Assessed alongside the building permit fee |
| Trade permits | Electrical, plumbing, gas and mechanical charged per discipline |
| Pre-technical review | Free of charge, but a required step on qualifying projects |
| Self-certification | Available to qualifying design professionals; confirm current scope |
| Records requests | Permits, certificates and plans via a Request for Public Records form |
| Re-inspection fee | Charged where an inspection has to be repeated |

Chandler trade permits
All the trades are permitted and inspected by the city under the 2024 codes and the 2023 National Electrical Code as amended by Ordinance 5108. Arizona has no state electrical permit.
Electrical permits
Required for service work, panel changes, photovoltaic systems, electric vehicle chargers and most wiring alterations. Chandler adopted the 2023 National Electrical Code rather than the 2024 — a specific choice recorded in Ordinance 5108, and worth getting right rather than assuming the newest edition applies.
Plumbing permits
Governed by the 2024 International Plumbing Code with Chandler amendments carried in the same ordinance and the corresponding article of the city code. Relocating a fixture takes a remodel out of the cosmetic exemption; a like-for-like water heater swap may not, under the city's homeowner guidance.
Mechanical and fuel gas permits
The city has adopted the 2024 mechanical, fuel gas and energy conservation codes alongside the rest of the family. The energy code is the one that most often surprises on a changeout, because it attaches requirements to equipment replacement that older editions did not.
Fences, walls and zoning clearance
Not a trade, but the most commonly missed Chandler requirement: fences and walls need zoning clearance regardless of height, so even a low garden wall goes through the Planner of the Day rather than straight to construction. Confirm the current rule before assuming a height threshold applies.

Chandler permit application: how to apply step by step
Here is how to get a building permit in Chandler, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Settle from the parcel that the work is in Chandler, then design to the 2024 codes with the 2023 electrical code as amended by Ordinance 5108.
Any proposed subdivision, site plan development, new building or substantial building addition requires pre-technical review. It is free and it is required, so put it at the front of the programme rather than treating it as optional.
If a qualifying registered design professional is on the team, self-certification changes the review path and the schedule. Confirm the current programme scope and eligibility with Building Safety before relying on it.
The manual carries the technical standards, administrative procedures, construction specifications and the application forms. Use it rather than assembling from general code knowledge.
Building code questions go to the Plan Reviewer of the Day; zoning questions to the Planner of the Day. Civil Engineering, Traffic Engineering and the Permit Counter each have duty representatives too.
Clear the inspection sequence, then get the occupancy certificate. A Certificate of Completion alone does not authorise occupancy under the city's amendments.
Inspections in Chandler
Building Safety reviews plans, issues permits and conducts building inspections for development projects, so the same function carries the project from drawings to close-out. Inspections follow the ordinary sequence, with work left available for inspection before it is covered.
The self-certification route changes what inspection means for a project. Where a registered design professional has certified compliance, the responsibility for that compliance has moved, but the city's inspections still confirm that what was built matches what was certified. The route shortens review; it does not remove the field check.
The occupancy question deserves restating because Chandler amended the code specifically to address it. A Certificate of Completion alone does not authorise occupancy of a building. Where a project produces a completion document at an intermediate stage, do not treat it as permission to occupy — the occupancy certificate is separate and it is the one that matters.
Copies of a permit, a Certificate of Occupancy or building plans are released through a Request for Public Records form rather than an informal request, which is worth knowing in advance on a renovation where you need the existing approved drawings before you can design.

Which codes does Chandler enforce?
The city has amended and adopted the 2024 editions of the International Codes with the 2023 edition of the National Electrical Code, through Ordinance 5108. All plans submitted for review on or after the first of July 2025 must be designed to comply. Any summary describing Chandler as being on the 2021 editions is out of date.
Can a design professional self-certify in Chandler?
Yes. The city allows registered design professionals to certify that a project complies with all applicable laws and codes. It changes the review path and can shorten the schedule considerably, but it also transfers the compliance responsibility to the certifying professional. Confirm the current programme scope and eligibility with Building Safety before relying on it.
Do I need a pre-technical review?
If your project is a proposed subdivision, site plan development, new building or substantial building addition, yes — the city requires it. It is free of charge, but it is a required step rather than an option, so it belongs at the front of the programme rather than somewhere in the middle.
Does a Certificate of Completion let me occupy the building?
No, and Chandler amended the adopted code specifically to say so. A Certificate of Completion alone does not authorise occupancy of a building. The occupancy certificate is a separate document and it is the one that permits lawful occupation.
Who do I call with a code question?
The Plan Reviewer of the Day for general building code questions, and the Planner of the Day for zoning. The department also runs duty representatives in Civil Engineering, Traffic Engineering and at the Permit Counter. Routing the question to the right desk is faster than a general enquiry.
What is the Unified Development Manual?
Chandler's single technical document, giving electronic access to more than 300 pages of municipal regulations, administrative procedures, technical standards and construction specifications. It is also where the application forms for permits, licences and other permissions live. Build submittals from it rather than from general code knowledge.
Do fences and walls need a permit?
They need zoning clearance regardless of height, which catches out people who assume a height threshold applies as it does in many jurisdictions. Contact the Planner of the Day even for a low fence, and confirm the current requirement before building.
How do I get a copy of a permit or plans?
Through a Request for Public Records form. Copies of a permit, a Certificate of Occupancy or building plans are not released informally. On a renovation where you need the existing approved drawings before you can design, start that request early.
What is the Directory of Regulatory Documents?
A summary the city publishes through the City Clerk of the current applicable ordinances, codes and substantive policy statements for every licence, permit or certificate required by law. Arizona law requires municipalities to maintain one. It is the fastest reliable route to Chandler's true adopted-code list, and documents not online can be inspected in hard copy at the Clerk's office.
Are accessory dwelling units allowed in Chandler?
Chandler is above the 75,000 population threshold in Arizona’s 2024 accessory dwelling unit statute (A.R.S. 9-461.18), so the statewide floor applies: at least one attached and one detached unit as a permitted use on any lot where a single-family dwelling is allowed, and the city must allow a unit of at least 75 per cent of the main dwelling’s gross floor area or 1,000 square feet, whichever is less. Private covenants remain enforceable.
Do I need a permit to replace my water heater?
The city publishes homeowner guidance listing certain like-for-like replacements that do not require a permit, and a straight water heater swap has appeared on that list. Note that this is the opposite of the rule in some other Arizona jurisdictions, where equipment replacement is expressly permit-required — so do not carry an assumption across city lines. Confirm the current Chandler position before starting.
What ends a Chandler project on paper?
The occupancy certificate, after every required inspection has passed. Do not stop at a Certificate of Completion: under the city's amendments it does not authorise occupancy on its own.
