Do you need a building permit in Roanoke Township, IL?
For unincorporated Roanoke Township, Woodford County uses a zoning permit/building permit process covering permanent, temporary and movable structures or uses unless exempted by the zoning ordinance.1 The county has not adopted a building code; that statement does not remove zoning, septic or floodplain requirements.2 Illinois also imposes statewide baseline building-code requirements, including in jurisdictions without locally adopted codes.3
The incorporated Village of Roanoke uses a separate municipal code, so establish whether the parcel is unincorporated before applying these township answers.6 For land elsewhere outside incorporated limits, see the Woodford County guide.6
Who handles building approvals in Roanoke Township?
Woodford County Building and Zoning Department issues zoning permits and processes plat approvals, variances, special uses and rezoning for unincorporated Roanoke Township.116 Call 309-467-3023 or email [email protected] for the county zoning office.11
For an unincorporated township zoning application, prepare the structure dimensions, location, intended use, construction cost and an elevation drawing or similar picture.12 A dwelling application cannot be processed until septic and soil erosion permits have been acquired.12 Private septic and well plan review remains with the Woodford County Health Department rather than the zoning counter.13
Does Roanoke Township have zoning, lot-size and small-home rules?
Unincorporated Roanoke Township follows Woodford County zoning, with district boundaries established by the official zoning map.614 In the Agriculture District, the minimum lot size is 2 acres except as provided by special use permit; residential and agricultural structures may cover at most 8% of the lot.915 In the Residential Single-Family District, minimum lot size depends on private sewage standards and Health Department review, except as provided by special use permit.16
Every dwelling unit in unincorporated Roanoke Township needs at least 800 square feet of habitable floor area, so a smaller tiny dwelling would not meet that dimensional standard.8 Ask Building and Zoning to identify the parcel district and applicable setbacks before choosing a house location.11
How do septic and well permits work in Roanoke Township?
The Woodford County Health Department reviews plans and issues permits for private septic systems and private wells in Roanoke Township, and inspects new or repaired systems.13 The published septic permit fee is $225, and the well permit fee is $100.7 Septic application review may take 2–7 working days, and final inspection must be requested at least 48 hours in advance.1718
Woodford County soil data rates only 5.7% of soils as not limited for a conventional septic drain field; that countywide rating makes site evaluation important but does not mean septic is impossible on a particular township lot.19 Ask the Health Department about the proposed water and sewage layout before committing to a home site.13
Can you live in an RV or manufactured home in Roanoke Township?
We could not confirm permission to occupy an RV or camp temporarily on private land in unincorporated Roanoke Township; ask Woodford County Building and Zoning about the proposed use before relying on an RV during construction.11 The township dwelling-size rule requires 800 square feet of habitable floor area per dwelling unit, which also matters when considering a tiny home.8
For manufactured-home treatment as a single-family detached dwelling in unincorporated Roanoke Township, the unit must be at least 24 feet wide, more than 35 feet long, installed on a permanent foundation, and have qualifying exterior siding and a pitched roof.20 Manufactured/mobile residences must meet HUD construction and safety standards.20 Ask the zoning office to confirm the district and proposed placement.11
Building a home in Roanoke Township: what comes first?
Start by confirming that the Roanoke Township parcel is unincorporated and identifying the county zoning district; the Village of Roanoke has a separate municipal code.614 Next, arrange Health Department review of the private septic and well plans, and obtain the septic and soil erosion permits needed before a dwelling zoning application can be processed.1312
Submit the zoning application with dimensions, location, use, construction cost and an elevation drawing.12 Obtain a floodplain development permit before starting regulated floodplain development.21 Check road access and any proposed land division: township tracts must abut a public or private road, and county plat procedures can also require municipal approval in an extraterritorial subdivision-control area.2223
Watch-outs
- An agricultural-building zoning permit fee exemption in unincorporated Roanoke Township does not eliminate other applicable approvals.10

- Woodford County Health Department handles private well permits, so arrange water-system approval as well as sewage-system approval.5

- 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.
