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

Rockdale generally requires a village building permit when you construct, enlarge, alter, repair, move, remove, improve, convert or demolish a building or other structure.1 The village’s explanation covers structures from a tool shed to a house, and a building permit may include grading, plumbing, mechanical and electrical services.1 Ask Village Hall about the exact work before ordering materials or beginning construction.1 Illinois does not issue building permits for privately funded construction; the applicable local government handles any required building permit.8

Who handles building applications and zoning questions in Village of Rockdale?

Submit Rockdale building permit applications to Village Hall, and use the village’s preliminary review to ask whether the proposed project fits Rockdale’s development guidelines.1 Village Hall’s building-process contact is (815) 725-8937.1 Rockdale routes submitted projects to its construction code services company for reviews and inspections.1 Rockdale’s own zoning ordinance governs land inside village limits; incorporated villages with zoning ordinances are excluded from Will County’s zoning jurisdiction.29 For land outside village limits, consult the Will County guide: the county building permit requirement applies to regulated work in unincorporated Will County.10

What does Village of Rockdale zoning mean for home and lot size?

Rockdale’s dimensional requirements must be read by zoning district rather than treated as a village-wide minimum.56 In Rockdale’s R-3 district, new multiple-family dwellings or apartment buildings require at least 900 square feet per dwelling unit and at least 1,600 square feet of lot area per family unit.56 Those requirements do not establish the minimum size for a detached single-family home.5 We could not confirm Rockdale’s complete setback or lot-coverage standards; ask Village Hall to review a proposed site plan against the parcel’s district before committing to a house layout.1

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

Rockdale prohibits tents, trailer-coaches, shacks, garages and the basement of an unfinished house used for residence purposes in R-1 and R-2 zones.3 The narrow R-1 exception concerns servants employed on the premises quartered in an accessory building without kitchen facilities; it does not provide a general trailer-coach residence exception.3 Do not plan to use a trailer-coach as your residence while building in those districts.3 We could not confirm a separate Rockdale tiny-home, accessory dwelling or temporary-camping rule; bring the proposed use and structure to Village Hall for preliminary review.1

How do septic and well approvals work inside Village of Rockdale?

Illinois requires plan approval from IDPH or the applicable local authority before constructing a new private sewage disposal system, including covered major changes to an existing system.7 Will County Health Department Environmental Health provides well and wastewater-system inspections and operates a Private Sewage Program; ask that office to confirm the approval path for a Rockdale parcel.4 Illinois also requires a permit from IDPH or an approved local health department before constructing, modifying or sealing a water well.11 A compost toilet does not remove the statewide requirement to dispose of other domestic wastes through a conventional private sewage disposal system.12 We could not confirm Rockdale’s sewer-connection requirements; ask Village Hall about sewer availability before designing private sewage disposal.1

Building a home in Village of Rockdale: what are the steps?

  1. Bring your proposed use and project to Village Hall for preliminary review against Rockdale’s development guidelines.1
  2. Submit the completed application, related forms, two copies of required plans and supporting documentation, including structural, energy and soils information if needed.1
  3. Allow for village and construction-code review; Rockdale describes basic residential review as typically taking two to three weeks, with major projects taking longer.1
  4. After approval, pay the building permit and required inspection fees so the village can issue the building permit.1
  5. Arrange inspections as work progresses, giving the village the required 24-hour notice.1

We could not confirm Rockdale’s certificate-of-occupancy requirement; ask Village Hall what final approvals your home needs before move-in.1

Watch-outs

  • Rockdale’s R-1 and R-2 residence prohibition includes the basement of an unfinished house, so unfinished construction is not a general temporary-housing option in those districts.3
  • Rockdale charges for missed, canceled or failed inspections; confirm scheduling with Village Hall.1
  • Illinois’s qualifying owner-occupant plumbing exception does not establish a general building permit exemption, and local plumbing permits may still be required.1314
