Do you need a building permit in Village of Coal City, IL?

Coal City’s Building Department identifies building permit applications for new construction and additions, with primary-structure applications obtained at Village Hall.1 The department also lists miscellaneous building permits for garages, sheds, fences, pools, decks, solar panels and other accessory work.1 Ask the Building Department which application covers your project and request the application checklist before arranging construction.1

Coal City has adopted the International Residential Code, 2021 Edition, with Village modifications, alongside other construction codes.9 Village building permit fees follow the Village Code’s fee schedule; request a current project-specific total rather than using a county fee schedule.10

Who issues building permits in Village of Coal City?

The Village of Coal City Building Department is the municipal starting point for building permit applications; contact the Building Official at 815-999-1112 or [email protected].1 The department’s webpage provides a building permit application checklist, zoning map, setbacks and size restrictions, and variance or conditional-use information.1

Coal City residential building permits remain valid for a year after issuance, and extensions for unfinished work require Planning Commission approval.11 Ask the Building Department for the inspection schedule and completion requirements for your specific project before work begins.1

Does Village of Coal City have zoning, and can you live in an RV or tiny home?

Coal City has its own municipal zoning code, so land inside village limits needs a Village zoning answer.2 Use the Building Department’s zoning map and setbacks information to ask about the parcel’s district, allowed dwelling type, minimum lot and dwelling sizes, setbacks and height limits.1 We could not confirm those district-specific dimensions or Coal City’s rules for RV occupancy, temporary camping, tiny homes or accessory dwellings; ask the Village Building Department about the proposed use before buying.1

Coal City also regulates subdivisions and minor land divisions, so ask about the Village review process before planning to split a parcel.12

How do septic permits and private wells work inside Village of Coal City?

For a Coal City parcel in Grundy County that needs private sewage disposal, Grundy County Health Department’s Environmental Health Division reviews system plans, issues septic permits and inspects installation.313 Contact Environmental Health at (815) 941-3115 or [email protected].4 Illinois requires private sewage system plan approval from the applicable authority before construction begins.14

We could not confirm Coal City’s municipal sewer-connection or private-well restrictions; ask the Village Building Department whether public water and sewer connections are required before designing a private system.1 Grundy County Environmental Health reviews private well permit applications, while Illinois requires a well permit before construction, modification or sealing begins.815

What are the steps for building a home in Village of Coal City?

Start by asking the Village Building Department to identify the parcel’s zoning and provide the applicable setbacks, size restrictions and building permit checklist.1 Resolve public utility requirements with the Village; if private sewage disposal is proposed on a Grundy County parcel, seek system plan review from Grundy County Environmental Health before construction.1314

Obtain the Village building permit application for primary structures at Village Hall.1 If the site is in a floodplain, obtain the Village development permit before starting development unless exempted by law; the application requires scaled site drawings, elevations, dimensions and project-cost information.5 Confirm the inspection schedule with the Building Department and plan around the residential building permit’s expiration.111

What should you check before buying land in Village of Coal City?

Ask the Village Building Department to review the intended dwelling, accessory structures and any proposed lot division against Coal City’s zoning and subdivision requirements.2121 Floodplain development in Coal City requires a Village permit, and the Village performs floodplain-compliance inspections and substantial-damage determinations.516

If the parcel needs septic, Grundy County’s soil figures show 0% rated not limited for conventional drain fields; that countywide rating calls for site evaluation, not a conclusion that septic is impossible.17 For land outside village limits, consult the Grundy County guide: the county’s unincorporated-area zoning rules have a different jurisdiction.18

Watch-outs

  • Illinois’s owner plumbing exemption does not establish a general exemption from building permits or local plumbing permits.67
  • Coal City floodplain development approval requires copies of other applicable federal, state and local approvals before the Village issues its permit.5
