Aurora, IL Building Permit Guide (2025–2026)
Direct Answer: The City of Aurora's Division of Building and Permits, part of Development Services, issues every building, electrical, plumbing, mechanical, fence, deck, and accessory-structure permit inside Aurora's city limits, which stretch across parts of Kane, DuPage, Kendall, and Will counties. As of January 1, 2026, Aurora enforces the 2024 edition of its adopted I-Series model construction codes under Ordinance 25-0321, which replaced the city's prior 2015 code editions while retaining the 2015 International Property Maintenance Code. Zoning, setbacks, and land-use rules are governed separately by Aurora's Unified Development Ordinance (UDO), Chapter 146 of the city code. Most residential and commercial permit applications, fee payments, and inspection scheduling run through the city's eTRAKiT online portal.
Verified against official municipal and state sources: July 13, 2026. Requirements change — confirm with the city before applying.
Key Takeaways
- The Division of Building and Permits at 77 S Broadway, 1st Floor, issues permits, reviews plans, performs inspections, and issues Certificates of Occupancy for the entire city.
- Aurora updated its adopted construction codes from the 2015 to the 2024 I-Series editions under Ordinance 25-0321, effective January 1, 2026, while keeping the 2015 International Property Maintenance Code in force.
- Aurora separately received a $200,000 Illinois Finance Authority grant to adopt and implement the Illinois Stretch Code, a more ambitious energy-efficiency standard layered on top of the base code.
- Illinois has no statewide residential building code — as a home-rule municipality, Aurora adopts and enforces its own; see Illinois building codes, explained.
- Zoning district, setback, and dimensional standards live in Aurora's Unified Development Ordinance (UDO), Chapter 146 — not the building code — and vary by zoning district.
- Applications, fee payment, and inspection scheduling go through the eTRAKiT online portal; some initial and revised submittals still route through email.
- Contractors working in Aurora generally need to be registered or licensed with the city — insurance, a surety bond, and (for electrical work) ICC certification are required.
Scope note: This article covers permitting inside the City of Aurora, Illinois only. It does not apply to Aurora, Colorado (a different city that many web searches surface by mistake), nor to neighboring Illinois municipalities such as Naperville, North Aurora, Montgomery, Oswego, or unincorporated parts of Kane, DuPage, Kendall, or Will counties — each runs its own building department and code.
Which Department Issues Permits in Aurora?
The Division of Building and Permits, part of the city's Development Services group, handles design-development pre-review meetings, plan review, construction inspections, and Certificates of Occupancy for every property in the city. Its office is at 77 S Broadway, 1st Floor, Aurora, IL 60505, open Monday through Friday, 8 a.m. to 5 p.m., reachable at (630) 256-3130 or by fax at (630) 256-3139.
Zoning questions — what you can build, how tall it can be, how far it must sit from the property line — are handled by a separate Planning and Zoning line at (630) 256-3080. Fence and accessory-structure applicants in particular are routed to Planning and Zoning for zoning-compliance questions and to Building and Permits for the permit itself and final inspections.
What Building Codes Does Aurora Enforce?
Aurora amended Chapter 12 of its Code of Ordinances, "Buildings and Building Regulations," to adopt the 2024 I-Series of model codes and recommended local amendments. The ordinance (File #25-0321) passed City Council on December 9, 2025, and took effect January 1, 2026, moving the city's construction code family forward from the 2015 editions it had used since 2018 while leaving the 2015 International Property Maintenance Code in place. The city's summary describes the update as addressing current safety standards, emerging technologies, and the city's Building Code Effectiveness Grading Score.
Separately, Aurora accepted a $200,000 Illinois Finance Authority grant to fund adoption and implementation of the Illinois Stretch Code, a more ambitious energy-efficiency standard than the state's base energy code, with the funding supporting staff training and technical assistance for builders.
Because Illinois has no statewide residential building code, every home-rule city sets its own construction code the way Aurora has here — see Illinois building codes, explained for the broader state framework and why your permit rules depend entirely on which municipality issues them.
What Work Requires a Permit — and What's Exempt?
Aurora's permits page lists categories that always require a permit and a short list of exemptions:
Generally requires a permit:
- Structural changes, new construction, additions, and interior remodels
- Roofing work
- New or replacement decks, fences, garages, sheds, pergolas, and gazebos
- Work on historic properties or in the public right-of-way
- Electrical, plumbing, and mechanical work
Generally does not require a permit:
- Interior cosmetic work such as painting and flooring
- Most window replacements
- Water heater replacement (with exceptions)
- Backyard patios that are not connected to a driveway
The city's full Permit List breaks these down further into residential, commercial, residential/commercial, and miscellaneous categories — covering everything from new tract housing and lodging houses to grease traps, tents, elevators, EV charging stations, and work in the right-of-way. If your project isn't obviously on either list, call Building and Permits before starting work.
How Do I Apply for a Building Permit in Aurora?
- Confirm the permit type against the city's Permit List; call Planning and Zoning at (630) 256-3080 first if you're unsure whether your zoning district allows the project.
- Assemble your documents. For site-related work (fences, decks, accessory structures, driveways), Aurora asks for a current plat of survey showing the structure's dimensions, materials, and placement relative to your property lines; the city does not survey your lot for you, so accuracy is your responsibility.
- Check HOA rules separately. If your property is in a homeowners' association, HOA approval is a distinct process from the city permit and is not verified by the city.
- Submit through eTRAKiT at auro-trk.aspgov.com/etrakit, or email initial submittals to bpcsrgroup@aurora.il.us (revisions go to a separate revisions address the city provides on rejection).
- Pay the application fee due at submittal; the balance of permit fees is due when the permit is ready to issue.
- Track plan review and respond to corrections through the same portal; commercial and complex residential projects may route through outside agencies (fire prevention, county health, utilities) as needed.
- Schedule inspections through eTRAKiT as work proceeds, and request a final inspection or Certificate of Occupancy once construction is complete.
What Does a Permit Cost?
Aurora publishes a current Permit Fee Schedule — the city notes its prior fee resolution dated to 2001 and was overhauled effective October 1, 2010 because the old fees no longer covered the city's cost of delivering permit services; a 2026 fee schedule is posted on that page. Because fee amounts differ by permit type and are revised periodically, don't rely on a number you find elsewhere — check the current schedule or request an estimate through eTRAKiT before budgeting.
One example the city documents in detail is the fence permit fee, which is calculated with three components:
| Fee Component | Amount |
|---|---|
| Application Fee | $50, non-refundable, applied toward the total balance |
| Permit Inspection Fee (PIF) | 1.25% of installation cost, $20 minimum |
| Permit Review Fee (PRF) | 15% of the PIF, $51 minimum |
Other permit types (new construction, additions, remodels) are generally calculated off declared construction valuation using the same style of percentage-based formula, but the applicable rates differ by category — see the Permit Fee Schedule or how much does a building permit cost for how valuation-based fee structures generally work.
Do I Need a Licensed or Registered Contractor?
Aurora requires most contractors working in the city to register or be licensed before they can pull permits, through its Licensing for Contractors program. Documented requirements include:
- A Certificate of Insurance naming the City of Aurora as primary and non-contributory additional insured
- Workers' compensation coverage meeting Illinois statutory minimums, with $1,000,000 general aggregate and $500,000 per-occurrence general liability
- A surety bond of $5,000, valid for at least one year
- Business registration with the Illinois Secretary of State, or a county DBA certificate, plus a designated Qualifying Party
- For electrical contractors specifically, current ICC certification (National Standard Master Electrician for commercial work, National Standard Residential Electrician for residential work) in lieu of municipal testing
Outstanding or expired permits under a contractor's name will block that contractor from renewing their registration or pulling new permits, so keeping prior jobs closed out matters if you plan to hire repeatedly.
What About Zoning, Setbacks, and Fences?
Zoning in Aurora is governed by the Unified Development Ordinance (UDO), which took effect in 2019 and combined the city's former zoning and subdivision codes into a single Chapter 146. Dimensional standards — minimum lot size, front/side/rear setbacks, height, and lot coverage — are organized into summary tables in UDO Article 4.2 and vary by zoning district (R-R, R-1 through R-4, mixed-use, and overlay districts each have their own numbers, plus a separate Small Residential Lot standard in parts of the city). Because these figures differ block to block, confirm your parcel's district and its specific setback table with Planning and Zoning or the city's zoning map rather than assuming a single citywide number — see what is a setback in zoning for how setback rules generally work.
Fence rules are one of the more fully documented parts of the UDO. Aurora's fence and wall regulations and its published fence requirements booklet set height limits by lot type and yard location:
| Lot Type | Front Yard | Interior Side Yard | Rear Yard |
|---|---|---|---|
| Interior lot | 3 ft solid / 4 ft open | 6 ft (lots ≥ 50 ft wide) or 4 ft (narrower lots) | 6 ft maximum |
| Corner lot | 3 ft solid / 4 ft open | 6 ft (≥ 50 ft wide) or 4 ft (narrower) | 6 ft interior rear; exterior side/rear 3 ft solid / 6 ft open (6 ft solid allowed if set back ≥ 5 ft) |
| Through lot | 3 ft solid / 4 ft open | 6 ft (≥ 50 ft wide) or 4 ft (narrower) | Interior rear 6 ft; exterior rear 3 ft solid / 4 ft open (6 ft beyond 30 ft from the street line) |
A few rules apply regardless of lot type: no fence, post, or footing may cross the property line; fences next to a public sidewalk need at least a 1-foot setback; within 15 feet of a street or driveway intersection, height is capped at 3 feet for sight-line safety; and chain-link or wire mesh is prohibited in front yards and exterior side/rear yards on residential lots. A fence permit requires a current plat of survey showing height, materials, and placement, and is separate from any HOA approval you may also need. See fence permit rules on height, setbacks, and property lines for how these concepts generally apply, then confirm Aurora's specific numbers before you build.
Can I Build an Accessory Dwelling Unit (ADU) in Aurora?
Aurora's UDO allows one detached accessory dwelling unit per single-family lot, under UDO §146-3.3.6.J. Key standards include a minimum lot size greater than 6,000 square feet, a maximum ADU size of 650 square feet, a height cap at the lesser of the principal dwelling's height or 24 feet, architecture and materials that are complementary to the primary house (metal facades aren't allowed), at least 360 square feet of usable private open space with each dimension at least 10 feet, and one additional off-street parking space accessed from the alley serving the lot. The property owner must occupy either the primary dwelling or the ADU, and an ADU may only be used as a short-term rental while the owner lives in the primary structure. ADUs are limited to specific zoning districts (including R-R, R-1 through R-4, and certain mixed-use and overlay districts) — confirm your parcel qualifies before you design one. If you're weighing a garage conversion instead of new construction, see can I convert my garage into an apartment (ADU) for how that specific path typically works.
Inspections and Certificate of Occupancy
Inspections are scheduled through eTRAKiT once your permit is issued, and Building and Permits performs them citywide. New construction, additions, and any change of occupancy require a final Certificate of Occupancy before the space can legally be used; the Division of Building and Permits issues these once final inspections pass.
Frequently Asked Questions
Is this the same as Aurora, Colorado?
No. Aurora, Illinois and Aurora, Colorado are two different cities with separate building departments, codes, and websites, and search results for "Aurora building permit" frequently mix the two. This article covers only the City of Aurora, Illinois (aurora.il.us), located in the Chicago suburbs across Kane, DuPage, Kendall, and Will counties.
Do I need a permit to replace my roof in Aurora?
Yes. Roofing work is listed among the categories that always require a permit on the city's permits page.
Do I need a permit for a small backyard patio?
According to the city's permits page, backyard patios that are not connected to a driveway generally do not require a permit, while patios tied into a driveway do. Confirm your specific project against the Permit List since patio configurations vary.
Can I install a fence in Aurora without a permit?
No. A fence permit is required before installing, reconstructing, enlarging, or structurally altering any fence, per the city's fence booklet, regardless of how short the fence is.
Does it matter which county my Aurora property is in?
For city permitting purposes, no. Because Aurora is a single home-rule municipality, the Division of Building and Permits and its adopted codes apply the same way whether your address falls in Kane, DuPage, Kendall, or Will county. County government becomes relevant mainly for services the county still provides (recording, some tax matters), not for building permits inside city limits.
How long does permit review take in Aurora?
The city does not publish a single fixed number that applies to every permit type; review time depends on project scope and current volume. Aurora references a separate review-timeframe handout tied to its eTRAKiT portal — check that resource or ask Building and Permits at (630) 256-3130 for a current estimate before you set a construction schedule.
Do I need a licensed contractor for permitted work, or can I do it myself?
Aurora's permit list and contractor program are built around registered/licensed contractors, but the city's permits page also references a DIY and Home Improvement resource for property owners doing their own work; if you're acting as your own contractor, confirm with Building and Permits which permits allow owner-performed work versus requiring a registered contractor.
Verify the Rules for Your Property
Code editions, fee schedules, and zoning district boundaries all change over time, and the specific numbers that apply to your lot depend on its zoning district, lot size, and location within Aurora. Before you apply, check GovCodex's Aurora permit catalog for the current permit types tied to your project, or run a permit check to see what your specific address and project actually require.
