Do you need a building permit in Herrick Township, IL?
A home or accessory building in unincorporated Herrick Township requires an Improvement Location Permit from Shelby County; the rule covers placing, erecting, altering or changing structures.1 The listed fee is $175 for a new residence and $125 for a residential addition or accessory building.1 Shelby County traditionally exempts aluminum carports and boat docks, rather than offering a blanket exemption for small structures.1 Construction subject to county permitting must follow the International Building and Residential codes adopted by Shelby County.8
Who handles building permits and zoning in Herrick Township?
Shelby County Zoning Office handles building permits and ordinance enforcement for unincorporated Herrick Township, rather than a separate township building counter.2 Contact the office at 217-774-5797 or [email protected]; the office is by appointment only.9 The office address is 315 1/2 E Main Street Shelbyville, Illinois 62565.9 Confirm whether the parcel is outside the incorporated Village of Herrick before using the county application, because county zoning excludes incorporated municipalities.2 For the broader unincorporated-area rules, see the Shelby County guide.2
Does Herrick Township have zoning for RVs and tiny homes?
Unincorporated Herrick Township is subject to Shelby County zoning; a township address does not mean the land is unzoned.2 Shelby County prohibits recreational vehicles as dwellings, including living, sleeping or housekeeping, except in locations lawfully established for that use, such as parks and campgrounds.4 A tiny home used as a residence must meet the 900-square-foot minimum unless a hardship variance is granted through the application process.5 Manufactured homes are permitted in the Agricultural District subject to the ordinance’s mobile-home requirements, including a 1-acre lot and a 900-square-foot dwelling minimum.10 Ask the zoning office to identify the parcel’s district and applicable setbacks before choosing a house footprint.9
How do septic permits and wells work in Herrick Township?
For a new private sewer system in unincorporated Herrick Township, obtain the Shelby County Health Department sewer permit before the county building permit can be issued.3 Illinois requires plan approval before new private sewage-system construction and notification to the Department or local authority at least 48 hours before work begins.11 Shelby County’s soil rating shows only 2.8% of soils as not limited for a conventional septic drain field; a site evaluation may point to an engineered system, rather than making septic impossible.12 Illinois also requires a permit before constructing, modifying or sealing a water well; ask the county health department which approved authority processes the application.7
What are the steps to build a home in Herrick Township?
- Confirm that the Herrick Township parcel is outside incorporated municipalities and arrange an appointment with Shelby County Zoning Office.29
- Determine the structure’s size and placement, and obtain the health department sewer permit first if installing a new private sewer system.93
- Apply for the Improvement Location Permit; Shelby County typically issues it within 15 business days, and construction must begin within 1 year before expiration.9
- Build to the county-adopted codes and apply for the Certificate of Occupancy along with the Improvement Location Permit application.813
- Obtain the Certificate of Occupancy before occupying a new, reconstructed or structurally altered building.13
What should you check before buying land in Herrick Township?
Check whether a Herrick Township parcel lies in Shelby County’s Flood Plain Overlay: ordinary permitted uses generally cannot require a structure intended for year-round occupancy, and other uses require Zoning Board findings.14 A new entrance onto a county highway requires an entrance/culvert permit and aerial map, submitted at least 2 business days before construction; contact Shelby County Highway Department for that road class.15 Work in a state-highway right-of-way instead requires authorization from the Illinois Department of Transportation before work begins.16 We could not confirm parcel-specific public-water or sewer connection obligations; ask Shelby County Zoning Office and the serving utility before relying on an off-grid design.9
Watch-outs
- The incorporated Village of Herrick is outside the county zoning jurisdiction described here; confirm the parcel boundary before applying these rules.2
- An RV is not an approved dwelling on ordinary private land in unincorporated Herrick Township merely because a house is under construction.4
- Illinois’s owner-occupant plumbing exemption does not establish a general owner-builder exemption from building permits or building codes.6
- We could not confirm a separate temporary-camping allowance for unincorporated Herrick Township; ask Shelby County Zoning Office before planning overnight stays.9

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
