Does Warrensburg, Illinois have zoning?

Yes. The Village of Warrensburg applies its own Zoning chapter (Chapter 980) to buildings and lots inside village limits1. Zone regulations are minimums that apply uniformly within each district1.

In the VRE-1 Estate Residential zone, the minimum lot is one acre and 150 feet wide5. Principal buildings need a 40-foot front yard, 15-foot side yards and a 40-foot rear yard6. Buildings are capped at 35 feet and coverage at 0.30 of the lot89. Accessory buildings in residential zones are limited to one story and 20 feet10.

Those figures cover the VRE-1 zone only6; other districts differ, so ask the village which district a lot is in. Minimum dwelling size, accessory dwellings and tiny homes are not something we could confirm.

Do you need a building permit in Warrensburg, and who issues it?

Yes. Inside the Village of Warrensburg, no building, parking area or structure may be erected, converted, enlarged, reconstructed or structurally altered without first obtaining a permit2. That permit comes from the village's zoning chapter; we could not confirm what the village's separate building-code chapter adds, including inspections, occupancy certificates or owner-builder rules.

The village hall is at11. Call or visit the village hall clerk to ask which office issues building permits and what plans they want.

Macon County Planning & Zoning issues building permits only outside incorporated cities, villages and towns, so its counter is the wrong stop for a lot inside Warrensburg12. Illinois itself does not issue building permits for privately funded construction; local government does13.

How do septic permits work in Warrensburg?

Macon County's ordinance says construction or repair of a private sewage disposal system may not start until a permit is obtained from the County Health Department4. The county health department's Environmental Health staff review plans, issue septic permits and inspect installation14.

We could not confirm whether the village's sewer chapters require a lot inside Warrensburg to connect to public sewer or water, so ask the village hall before planning a septic system. Private water wells also need a permit through the county health department7. Macon County is also rated poorly for conventional drain fields: only about 2.6% of soils are rated not limited15, so expect a site evaluation and possibly an engineered system.

Can you live in an RV or travel trailer in Warrensburg?

Only briefly. A travel trailer may not be parked on a private lot or tract in the village for more than 30 days3. It may be used for sleeping only, with no cooking3. Owners may store their own trailer on their own premises without the 30-day limit3.

On streets, alleys and highways a travel trailer may stop for no longer than two hours16. The village's rules on mobile and manufactured homes outside a licensed park, and on tiny homes, are not something we could confirm.

Building a home in Warrensburg: the steps, in order

  1. Ask the village hall which zoning district the lot is in and confirm lot area, width and setbacks5.
  2. Obtain the village permit before any construction starts2.
  3. Get a septic permit from the Macon County Health Department, or confirm with the village whether public sewer is required4.
  4. Get a well permit if the lot uses a private well7.
  5. Ask the village whether a certificate of occupancy is needed before moving in.

What stays with Macon County, and what to check before you buy

Septic and well permits stay with the Macon County Health Department47. Land outside village limits falls under county rules instead; see the Macon County page for those.

For tax context, Macon County's effective property tax rate is about 2.1%17. Confirm flood exposure for the lot with the village; we could not confirm a village floodplain rule.

Watch-outs

  • We could not confirm the village's building-code chapter, inspection steps or occupancy certificate; ask the village hall clerk at 155 East Main Street before you buy11.
  • Setback, lot and height numbers here are for the VRE-1 zone only6.
  • The county's building permit and zoning rules do not apply inside village limits12.
