Joliet IL bathroom remodel permit rules — the basics

Joliet's bathroom remodel permit process follows the city's standard permit workflow — no in-person counter issuance, email or drop-box application, contractor-must-pull-permit rule for contracted work. The City of Joliet requires building permits for all new construction and for alterations to existing buildings, "including alterations or changes in the mechanical or electrical systems." Bathroom remodel work that alters the plumbing system (drain relocation, new fixture rough-ins), electrical system (new circuits, new outlets), or structural elements (wall removal) falls within this requirement.

Joliet's electrical contractor licensing is a distinctive feature compared to Naperville: Joliet accepts electrical contractor licenses from a specific list of Illinois municipalities and licensing bodies, including Chicago, Deerfield, Downers Grove, Elgin, Orland Park, Ottawa, Schaumburg, Libertyville, Woodstock, Peoria, Springfield, and the CLEC Certificate. This is different from Naperville's unique city-specific registration system. An electrician licensed in one of these jurisdictions (or holding a CLEC Certificate) can perform permitted electrical work in Joliet; electricians not licensed by one of these specific bodies may not be eligible to pull electrical permits in Joliet. Verify any electrical contractor's licensing eligibility for Joliet before signing any contract — call the Building Division at (815) 724-4070 to confirm.

ComEd (Commonwealth Edison) provides electricity to most Joliet residential properties. For any bathroom remodel work that requires electrical service coordination — service upgrades related to additional load from new bathroom heating systems or similar — contact ComEd. Nicor Gas provides natural gas; for bathroom work involving gas-fired water heaters adjacent to the bathroom or radiant heating, any gas line modification requires an Illinois-licensed plumber and a plumbing/gas permit.

Illinois has not adopted California's Civil Code §1101.4 whole-house plumbing fixture upgrade mandate. A bathroom permit in Joliet requires only that the permitted work comply with the current Illinois Plumbing Code. No obligation to upgrade fixtures in other bathrooms or throughout the house. Joliet's older housing stock — including a substantial inventory of homes from the early to mid-20th century in the historic districts — also means that pre-1978 properties trigger EPA RRP lead paint requirements when renovation work disturbs painted surfaces. Verify contractor EPA RRP certification before signing any bathroom remodel contract on a pre-1978 Joliet property.

Three Joliet bathroom remodel scenarios

Scenario A
Cosmetic bathroom update in a 1990s Joliet subdivision — permit-free scope
A homeowner in a 1990s subdivision near Route 59 is updating a hall bathroom: new tile throughout, new vanity cabinet and countertop, new toilet at the same flange location, new light fixture on the existing circuit, and a repainted exhaust fan cover (fan stays in place). No drain relocation. No electrical circuit additions. No wall structural changes. This is entirely cosmetic work that doesn't modify the plumbing, electrical, or structural systems — no permit is required in Joliet. The entire scope falls under the category of work that maintains existing systems without altering them. Even in Joliet's stricter application environment (contractor-must-pull, email-only applications), cosmetic work isn't subject to permit requirements. Total project cost: $5,000–$15,000 depending on tile selection and fixture quality. Note: even without permits, work must be performed properly — a new toilet installation that doesn't create a proper wax seal is a plumbing problem regardless of permit status.
No permit required (cosmetic scope, no system modifications); no California-style whole-house fixture upgrade triggered; project cost $5,000–$15,000
Scenario B
Tub-to-walk-in-shower conversion with drain relocation — plumbing and electrical permits
A homeowner wants to remove the tub/shower combination in the master bathroom and install a custom walk-in shower. The drain must be relocated from the tub drain location to a new shower drain position. A new exhaust fan is required in a better location to adequately ventilate the larger shower, requiring a new 120V circuit. A heated floor system adds a 240V circuit. This scope requires three permits in Joliet, all applied for through email to permitapplication@joliet.gov: (1) plumbing permit for the drain relocation — Illinois-licensed plumber required; rough-in inspection before shower pan and tile cover the drain; (2) electrical permit for the exhaust fan circuit and heated floor circuit — electrical contractor must hold one of Joliet's accepted licenses (Chicago, Deerfield, Downers Grove, Elgin, Orland Park, Ottawa, Schaumburg, Libertyville, Woodstock, Peoria, Springfield, or CLEC); (3) building permit may be required if any walls are altered for the walk-in shower configuration. Per Section 8-36, the respective contractor pulls each permit — plumber pulls plumbing, electrician pulls electrical. The shower waterproofing inspection is the most critical quality checkpoint before tile: a walk-in shower without proper waterproofing membrane over a properly sloped shower pan is the most common source of bathroom moisture damage in Will County homes. Project cost: $12,000–$28,000 for a high-quality custom walk-in shower conversion in Joliet.
Plumbing + electrical permits (+ building if walls altered); contractor must pull respective permit; Joliet-accepted electrical license required; shower waterproofing inspection critical; project cost $12,000–$28,000
Scenario C
Bathroom in pre-1978 Joliet home — lead paint, old plumbing, and permit process together
Joliet has a substantial inventory of pre-1940 and pre-1960 homes in historic neighborhoods near downtown and in established residential areas along the Rock River and Des Plaines River corridors. A bathroom remodel in a 1952 Joliet home involves three overlapping considerations: permit process, aging systems, and lead paint. For the permit: plumbing permit for any drain or supply modifications; electrical permit for circuit additions (electrician must have Joliet-accepted license); building permit for structural changes. The contractor must pull the permit(s) per Section 8-36 and must have current Joliet registration. For aging systems: 1952 homes commonly have cast iron drain stacks, galvanized steel supply lines, and original electrical wiring — opening the bathroom during renovation often reveals conditions that should be addressed while walls are open. A licensed Illinois plumber can assess the drain stack condition and supply lines; a Joliet-licensed electrician can evaluate the existing bathroom circuit condition. For lead paint: a 1952 home is certain to have lead paint on walls, trim, and bathroom fixtures. EPA RRP rules require certified contractors for renovation work disturbing more than 6 sq ft of painted surfaces — nearly unavoidable in a bathroom remodel. Verify EPA RRP certification of all contractors before signing any contracts for this home. Project cost for a bathroom remodel in a pre-1978 Joliet home: $10,000–$30,000 with RRP compliance and likely incidental system updates.
Plumbing + electrical + possible building permits; contractor must pull permits (Section 8-36); Joliet-accepted electrical license; EPA RRP certification required (pre-1978 home); aging system assessment recommended; project cost $10,000–$30,000

Common questions about Joliet IL bathroom remodel permits

Which electrical contractor licenses does Joliet accept?

Joliet accepts electrical contractor licenses from the following: Chicago, Deerfield, Downers Grove, Elgin, Orland Park, Ottawa, Schaumburg, Libertyville, Woodstock, Peoria, Springfield — and CLEC Enterprises Certificate holders. An electrician holding a license from one of these jurisdictions can perform permitted electrical work in Joliet. An electrician with only a state-level license or licenses from other municipalities not on this list may not be eligible. Call the Building Division at (815) 724-4070 to confirm a specific electrician's licensing eligibility for Joliet work before signing any contract.

Can a homeowner pull their own bathroom permits in Joliet?

For bathroom work a homeowner personally performs (no contractors hired), the homeowner may be able to apply for permits in their own name. The Section 8-36 contractor-must-pull requirement applies when a contractor is performing the work. For most bathroom remodel work involving plumbing and electrical modifications, however, licensed trade contractors are required to perform the work regardless of who pulls the permit — a homeowner cannot self-perform licensed plumbing or electrical work without appropriate licensing. Call the Building Division at (815) 724-4070 to confirm the applicable permit and licensing requirements for your specific scope.

Who provides electricity and gas in Joliet?

ComEd (Commonwealth Edison) provides electricity to most Joliet residential properties. Nicor Gas provides natural gas to most Joliet residences.
