Do you need a building permit in Aurora, IL?

Aurora requires building permits for new construction, additions, structural changes and interior remodels, including work done by homeowners.¹ Interior cosmetic work such as painting, flooring and carpeting is listed among the city’s building-permit exemptions.¹ Exterior work on historic property or property in the FoxWalk District always requires a permit, so the address matters as well as the scope of work.¹ Aurora administers its own building code and adopted model codes; the city’s plan review checks proposed construction before work begins.⁷⁸

Who issues building permits in Aurora, and what do they cost?

Aurora’s Division of Building and Permits is the city contact for building applications and inspections at (630) 256-3130, with its counter at 77 S Broadway, 1st Floor Aurora, IL 60505.¹ The residential new/addition schedule lists a $278 application fee, a $1,817 minimum inspection fee, a $278 minimum plan-review fee and a $115 certificate-of-occupancy fee.⁵ Those are separate charges, and the schedule also lists engineering, water, sewer and other possible charges rather than a single all-inclusive price.⁵ Ask Building and Permits for the project-specific fee calculation.

Does Aurora have zoning, and can you live in an RV or tiny home?

Aurora provides a property zoning search, zoning map books and an online zoning ordinance for land inside city limits.² The city’s Zoning & Planning Division takes specific questions through its Land Use Inquiry form.⁴ We could not confirm Aurora’s residential RV, temporary camping, tiny-home or accessory-dwelling rules; ask Zoning & Planning to evaluate the proposed use at the parcel’s address. We also could not confirm district-specific lot sizes, setbacks or minimum dwelling sizes. Request those district requirements before choosing a home design or treating a parked RV as temporary housing.

How do septic permits and private wells work inside Aurora?

For Aurora land under Kane County Health Department jurisdiction, new septic systems, repairs and capacity upgrades require a KCHD septic permit, and permitted septic work must be performed by a licensed septic contractor.⁹ A soil evaluation is required for a new system or renovation involving the septic field; a tank replacement does not require that evaluation.⁹ Aurora separately regulates use of and connection to its sewer system.¹⁰ Ask the city about sewer access before planning private sewage disposal. Illinois requires a permit before constructing, modifying or sealing a private well.⁶ We could not confirm a single septic or well office serving every Aurora address; verify the parcel’s county and health authority first.

Building a home in Aurora: what are the steps, in order?

1. Identify the parcel’s zoning and county using Aurora’s property tools, then submit a Land Use Inquiry for the proposed home and any temporary living arrangement.²⁴
2. Discuss the project with Aurora’s Development Services Team before submitting plans; the team answers project questions and explains review and approval processes.⁴
3. Submit the city building application through the E-Trakit online portal and obtain plan review before construction.¹⁸
4. Pay outstanding building-permit fees and satisfy city contractor licensing requirements before permit issuance.¹
5. Follow the inspection sequence listed on the issued building permit, and ask Building and Permits about the project’s occupancy certification.¹¹¹

What should you check before buying land in Aurora?

Aurora’s Engineering Division provides floodplain maps and FEMA resources for assessing a property’s flood risk; contact the city division rather than assuming a county floodplain counter handles the address.¹² Work in Aurora’s public right of way requires a permit and may require a licensed public works contractor.¹ For work within a state-maintained roadway’s right of way, IDOT requires its own permit before work starts.¹³ If an Aurora property already has septic, Kane County Health Department does not provide septic inspections for home sales or mortgage transactions.¹⁴ For land outside Aurora city limits, use the Kane County guide for the county’s unincorporated-area building and zoning rules.¹⁵¹⁶

Watch-outs

• Aurora homeowners doing their own construction must still apply for required building permits.¹
• Aurora’s homeowner waiver requires continued owner occupancy for at least 6 months and matching government-issued identification; electrical work exceeding $500 requires a licensed electrical contractor.¹
• We could not confirm Aurora’s RV or tiny-home occupancy rules; ask Zoning & Planning before arranging temporary housing.⁴
• Kane County Health Department generally requires public-sewer connection when available, subject to its documented exceptions; a septic plan is not a substitute for checking sewer access.¹⁷
