Tazewell County, Illinois Building Permit Guide

Tazewell County sits across the Illinois River from Peoria at about 130,000 residents, part of the Peoria metropolitan area and anchored by Pekin, East Peoria, Morton and Washington. Its Community Development department permits and inspects unincorporated construction, while the cities run their own departments.

This guide covers the county’s unincorporated-area role, the river and manufacturing context, the statewide layers, and where city work goes instead.

This guide covers unincorporated Tazewell County. Pekin, East Peoria, Morton, Washington and the other municipalities each run their own permitting.

What requires a building permit in Tazewell County?

Because the code edition and its amendments are set locally, the exempt list and thresholds differ from one jurisdiction to the next — a project waved through in one town needs a full permit set in the next. An exemption from a building permit is never an exemption from zoning, the statewide energy or plumbing codes, or an electrical or plumbing permit. Confirm scope with Community Development before work starts.

The statewide layers that apply everywhere

Three Illinois codes apply statewide: the Illinois Energy Conservation Code, which applies even where a town does not actively enforce it; the Illinois Plumbing Code, from the Department of Public Health, which also licenses plumbers (a local government may adopt a stricter plumbing code, and Chicago has its own plumbing and energy codes and licenses its own plumbers); and the Illinois Accessibility Code. In unincorporated Tazewell County, Community Development administers the county’s adopted building code alongside zoning and floodplain review along the Illinois River; the statewide Illinois codes apply on top.

Illinois leaves building codes to local government, but since 1 January 2025 any local code must regulate structural design at least as strictly as baseline editions of the International Building, Existing Building and Residential Codes, and where no code was adopted the statute sets minimums for commercial buildings and new homes (Public Act 103-0510).

Who handles permitting in Tazewell County?

Community Development handles permitting and inspections for unincorporated Tazewell County; the municipalities handle their own.

Community Development is the authority for unincorporated Tazewell County, combining building permitting with zoning and land-use review. The Illinois River corridor brings floodplain considerations, and the region’s heavy-equipment manufacturing base drives industrial work, especially around East Peoria. Because the metro is heavily incorporated, confirm the jurisdiction from the parcel first.

The county administers its adopted building code; the statewide Illinois energy, plumbing and accessibility codes apply on top, with plumbing tied to a state-licensed plumber.

In 2025, building permits issued in unincorporated Tazewell County authorized 22 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Unincorporated residential work spans riverfront properties and rural subdivisions. Re-roofs, decks, solar and EV chargers need permits, plumbing is tied to a state-licensed plumber, and contractors register locally before pulling a permit.

Commercial permits

Commercial and industrial work runs from heavy-equipment and manufacturing facilities to river terminals and retail, all subject to the adopted code, the statewide energy and accessibility requirements, and specialised review, with locally registered contractors and state-licensed plumbing.

Registration, trade licences and design professionals

Practically, three credential layers appear on Illinois projects: local contractor registration with Community Development; state licences for plumbing and roofing; and, on commercial and larger residential work, drawings from an Illinois-licensed design professional. Confirm what Community Development requires for the specific building before filing.

Illinois licenses plumbers through the Department of Public Health and roofing contractors through the Department of Financial and Professional Regulation; there is no state general contractor or electrician licence, and many jurisdictions require local registration.

Tazewell County permit costs and fees

Budget the county building permit fee (which includes plan review), separate electrical, plumbing and HVAC permits, and any floodplain review. Tazewell County charges by floor area, not valuation: a home, addition or alteration pays from $200 (200 sq ft or less) to $550 (3,001 to 4,000 sq ft), plus $50 for each further 1,000 sq ft, and commercial buildings pay by larger floor-area bands.

Illinois sets one useful certainty in law: once a permit is issued, the code requirements in effect on January 1 of the year you applied govern for the life of that permit, so a mid-project code change will not move the target. Fee schedules, though, are local and change, so a figure from a neighbouring town is not reliable — ask Community Development for the schedule in force on your filing date.

Trade permits and who may pull them

Plumbing follows the Illinois Plumbing Code and a licensed plumber (Chicago licenses its own plumbers); electrical and mechanical work follow the locally adopted codes and local licensing or registration. Trade credentials in Illinois

How to apply for a Tazewell County building permit

Review, corrections and what actually causes delay

In Illinois, the first cause of delay is uncertainty over jurisdiction and the applicable code edition — filing under the wrong amendments, or with the county when a municipality should have it. After that come missing local contractor registrations, a plumbing scope not tied to a state-licensed plumber, energy-code documentation, and a submittal that did not match what Community Development requires. Build the review time into the schedule and confirm the checklist before filing.

A building permit carries a validity period set by Tazewell County; confirm the expiry on phased or delayed work before it passes. Permit validity in Illinois

Inspections in Tazewell County

Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and energy, fire systems on commercial work, and final, with a certificate of occupancy before use. Riverfront and floodplain parcels add elevation and site verification.

Illinois is tightening inspector qualifications: from January 1, 2027, those who perform building inspections must hold International Code Council certification, with a grace period after hire. Confirm the notice Community Development needs and schedule around its inspection windows.

Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings, energy documentation and your correction responses available on site.

Tazewell County permit search and official resources

Permit records in Illinois sit with the local authority that issued them. Where Tazewell County Community Development is the authority for unincorporated Tazewell County, it holds the building permit, the inspection history and the certificate of occupancy. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — and confirm the code edition that was in force.

Frequently asked questions

Where do I get a Tazewell County building permit?

From Community Development, for unincorporated areas, based in Pekin; Pekin, East Peoria, Morton, Washington and the other municipalities run their own departments.

Do river parcels have extra rules?

Often. Illinois River floodplain review can apply to riverfront parcels; confirm with Community Development early.

How do I know if my parcel is unincorporated?

Confirm with Community Development; the Peoria metro is heavily incorporated, so many parcels file with a municipality instead.

Is plumbing handled locally?

Partly. The Illinois Plumbing Code and plumber licensing are statewide (Department of Public Health), but a local government may adopt a stricter plumbing code, and plumbing permits and inspections are handled by the local building department where it runs them. In Tazewell County, confirm with the department.

Do contractors register with the county?

Permit-pulling trades typically register locally with the county; plumbing and roofing are state-licensed.

How do I run a Tazewell County permit search?

Community Development holds records for unincorporated areas; municipal records sit with each city.
