Do you need a building permit in Virginia, IL?
Virginia requires the owner or builder to obtain a city building permit before constructing any building.1 Removing or demolishing a building or structure also requires a city building permit.1 Virginia has adopted building codes, with copies on file in the City Clerk’s office.10
Illinois statewide building-code baseline requirements took effect in 2025, and locally adopted residential codes must meet minimum structural requirements of the International Residential Code.11 Ask the city Zoning Enforcement Officer which code editions and inspection stages apply to your proposed work before commissioning plans; we could not confirm a general city construction-inspection schedule.
Who issues building permits in Virginia, and how do you apply?
Virginia building-permit applications must be in writing, filed with the city Zoning Enforcement Officer, using forms available at City Hall.12 Contact Virginia City Hall at 217-452-7786 or [email protected] to request the forms and the current officer’s contact details.13 The city website also says the Zoning Board meets as needed at City Hall.13
Keep occupancy approval on your application checklist: Virginia prohibits using a newly constructed or altered structure, or beginning a new, changed or expanded premises use, until the Zoning Enforcement Officer issues a certificate of occupancy.5 Ask the officer for the current building-permit fee schedule and required submission materials.
Does Virginia have zoning, lot-size rules and setbacks?
Virginia’s zoning code identifies single-family residential districts and a two-family and multi-family residential district.2 Ask the city Zoning Enforcement Officer to identify your parcel’s district and permitted use before choosing a house design.
For single-family lots in any Virginia district where neither public water nor public sewer is available, minimum lot width is 100 feet and minimum area is 20,000 square feet.6 Lots without public sewer must also be sufficient for an on-site sewage disposal system.6 The unserved-lot rule therefore does not replace septic approval from Cass County Health Department.64 We could not confirm district-specific setbacks, minimum dwelling size, lot coverage or height limits; request those measurements from the city officer.
How do septic permits work inside Virginia?
Cass County Health Department handles private sewage disposal permitting inside Virginia, and constructing, altering or extending an individual system requires a health-department permit.34 The Board of Health may refuse a septic permit where public or community sewerage is available, so establish sewer availability before paying for a septic design.4
Illinois requires sewage-system plan approval before construction and notice to the responsible department or local authority at least 48 hours before work begins.14 A homeowner may install or service a system serving the homeowner’s personal residence, but a valid permit remains required.7 A homeowner-installed system cannot be covered or operated until the Health Department inspects it and issues written approval.8
Can you live in an RV or tiny home in Virginia?
We could not confirm Virginia’s permission for living in an RV, temporary camping, tiny-home occupancy or an accessory dwelling on a private lot. Ask the city Zoning Enforcement Officer about the exact proposed use, including whether you intend to stay during construction, before buying an RV or ordering a tiny home.
Virginia’s occupancy-certificate rule reaches new, changed and expanded uses even when no structure is constructed or altered.5 A proposal without building work therefore still needs scrutiny under the city’s use-approval rule.5 Virginia’s site restrictions prohibit open wells, privies and cesspools; do not plan a privy as your sanitation solution.6 Ask Cass County Health Department to review the proposed sewage system separately.
Building a home in Virginia: what are the steps, in order?
- Ask Virginia’s Zoning Enforcement Officer to confirm the parcel’s district, allowed use and dimensional requirements; the city publishes residential zoning districts.2
- Establish sewer availability and, if septic is proposed, obtain Cass County Health Department’s septic permit and the required plan approval before construction.414
- Obtain City Hall’s building-permit forms, submit the written application to the city officer and secure the city building permit before construction.121
- Ask the city officer for construction-inspection scheduling; obtain written health-department inspection approval before covering or using a homeowner-installed septic system.8
- Notify the city officer in writing when the new use is ready to begin and obtain the certificate of occupancy before use.5
What should you check before buying land in Virginia?
Virginia lots must abut a public thoroughfare with at least 30 feet of frontage; qualifying pre-existing lots without public-street frontage need an access easement or right-of-way at least 20 feet wide.15 Verify frontage and recorded access before treating a vacant parcel as a building site. A driveway connecting to an Illinois state highway requires an IDOT permit before work begins.16
Illinois requires a permit from IDPH or an approved local health department before constructing, deepening, modifying or sealing a private well; ask Cass County Health Department who administers your application.9 For property outside Virginia city limits, use the Cass County guide for the county’s building-permit and zoning requirements in unincorporated areas.1718
Watch-outs
- Public or community sewer availability can prevent approval of a private septic system inside Virginia.4

- Virginia has city residential zoning districts.2 We could not confirm RV occupancy, tiny-home permission or district-specific setbacks; ask the city Zoning Enforcement Officer before committing to a parcel or design.
- The Illinois owner-occupant plumbing exemption is limited to qualifying single-family plumbing work and does not create a general exemption from building permits.19
