Do you need a building permit in the Village of Maryville, IL?

Maryville’s Building & Zoning Department issues building permits and reviews plans for new construction and alterations to existing structures.1 The department also inspects new or substantially altered buildings for compliance with applicable codes and laws.1 Ask Maryville Building & Zoning which building permit and inspection schedule apply to your proposed work.1 Illinois does not issue building permits for privately funded construction; building permit requirements are administered locally.8 An owner doing the work should not assume a building permit exemption: Illinois’s owner-occupant plumbing exemption is limited to qualifying plumbing work and retains code and inspection requirements.7

Who issues building permits in the Village of Maryville?

Start with the Village of Maryville Building & Zoning Department for building permit applications, construction plans and building inspections.1 The village offers an online application process: create or log into an account, select the appropriate permit, complete the application and submit electronically.9 Use the village’s Applications / Permits page to begin that process.9 Maryville’s own zoning applies inside village limits; for land outside the village, Madison County’s guide covers the county building permit requirement for unincorporated land.210 Septic applications inside Maryville still go to Madison County.3

Does the Village of Maryville have zoning and minimum lot sizes?

Maryville has its own zoning regulations, so identify the parcel’s district before choosing a house plan or dividing land.211 In Maryville’s A Agricultural district, the schedule allows a dwelling per 2 acres and requires minimum lot width and mean depth of 200 feet.12 In SR-1, the minimum lot area is 16,000 square feet, with minimum width of 100 feet and mean depth of 130 feet.5 In SR-2, the minimum is 10,400 square feet, with minimum width of 80 feet and mean depth of 130 feet.6 Maximum lot coverage is 20% in those residential districts.13 For a proposed subdivision, Maryville’s code encourages consultation with the Village Building and Zoning Administrator and Planning Commission before the preliminary plat.14

How do septic permits work inside the Village of Maryville?

A Maryville property owner must obtain a written county permit before constructing a private sewage disposal system; Madison County issues the permit and sets the septic fee schedule.153 Madison County Planning & Development permits and inspects private sewage installation, and allows private sewage only where public sewer is unavailable, cannot be extended to the property line and acceptable soils are present.16 Illinois requires plan approval before septic construction and notification to the applicable authority at least 48 hours before work begins.17 In Maryville, when public sewer becomes available, the building sewer must connect within 90 days.18 Septic therefore needs both a suitable site and an answer about sewer availability before you commit to a design.16

Can you live in an RV or tiny home in the Village of Maryville?

Maryville’s RV rule allows temporary guest occupancy with a Village Building and Zoning Administrator permit for no more than one week; it does not establish permission for ongoing RV residence while building.4 Maryville separately prohibits residential occupancy of temporary structures except as specifically allowed by its zoning chapter, with the Board of Zoning Appeals able to approve a compatible use for a reasonable time after application.19 RV storage also has limits: no more than 2 qualifying vehicles in the open on a residential lot, and maximum dimensions of 13 feet high and 32 feet long.4 Subdivision covenants may be stricter than the village RV rules.4 We could not confirm a tiny-home or accessory-dwelling rule; ask Maryville Building & Zoning about the proposed structure and intended occupancy.1

Building a home in the Village of Maryville: what steps come first?

  1. Ask Maryville Building & Zoning to review the proposed construction and confirm the parcel’s zoning district before finalizing the plans.12
  2. Establish sewer availability; if private sewage is needed, obtain Madison County’s septic approval before construction.1615
  3. Submit the appropriate village building permit application through Maryville’s online application process.9
  4. Arrange the village construction inspections and the county private sewage inspections that apply to the project.116

We could not confirm Maryville-specific well, floodplain or driveway requirements; ask the Village Building & Zoning Department which approvals your parcel needs.1 Illinois requires a permit before constructing, deepening, modifying or sealing a private well, from IDPH or an approved local health department.20

Watch-outs

  • Maryville’s permitted week-long RV guest stay does not establish permission to occupy an RV throughout house construction.4
  • Maryville requires connection within 90 days when public sewer becomes available to a property using private sewage disposal.18
  • We could not confirm a Maryville minimum dwelling floor area or agricultural construction exemption; ask Village Building & Zoning before selecting a small house or farm-building plan.1
