Do you need a building permit in Red Bud, IL?

Red Bud requires a city building permit for new single- and two-family dwellings.1 The city code adopts the 2003 International Residential Code for those homes, while Illinois statewide baseline requirements also apply; ask the Code Administrator which code requirements govern your proposed construction today.910

Red Bud residential inspections cover foundation, below-grade plumbing, backfill, frame and electrical, above-grade plumbing, and occupancy.11 Owners or agents must request those inspections at least 48 hours in advance, and a failed inspection requires correction and reinspection.11

Who handles building permits in Red Bud, and what do they cost?

Start a Red Bud building project with the city Code Administrator at 618.282.3339, at 525 Power Street, Red Bud, IL 62278.12 The Zoning and Planning Department reviews zoning permits and site plans and helps applicants through zoning approval.12

The current residential application charges $0.15 per square foot for principal structures, including attached garages, basements and additional stories, with a $45 minimum payable at application.13 Accessory structures cost $0.10 per square foot with a $45 minimum; fences cost $45 regardless of length.13 The city code separately lists a $300 residential inspection fee and $50 reinspection fee; ask the Code Administrator how those inspection charges combine with the application’s building-permit charges.14

Does Red Bud have zoning, lot-size rules and setbacks?

Red Bud administers its own zoning ordinance inside city limits, regulating land use, building placement, lot size, signage and other development standards.2 The city reviews site plans, zoning changes and special-use requests, and its Planning Commission reviews subdivision proposals.215

Before buying a Red Bud lot, ask the Code Administrator to identify the zoning district and give you the applicable lot-area, setback, height and dwelling-size requirements for your proposed use.12 We could not confirm the district-specific dimensional limits or a city agricultural exemption; request those answers from the Code Administrator before choosing a house footprint or assuming a barn is exempt.12

How do septic permits and sewer connections work in Red Bud?

Red Bud requires a written City Superintendent permit before construction of a private sewage disposal system; the city permit and inspection fee is $50.6 Randolph County Health Department also administers private sewage permits and inspections, so ask both offices which approvals your address needs before excavation.3164

Red Bud will not issue a subsurface soil-absorption permit for a lot smaller than 10,000 square feet.6 The Superintendent must be notified for final inspection before underground portions are covered.17

For covered city properties abutting a street, alley or right-of-way with a city sanitary sewer within 100 feet of the property line, connection is required at the owner’s expense within 90 days after official notice, subject to downstream capacity.18 A private-system plan therefore starts with checking public sewer availability.418

Can you live in an RV or tiny home in Red Bud?

Red Bud prohibits using camping trailers or similar recreational vehicles as living quarters except in a camping trailer park.5 Do not plan to live in an RV on an ordinary city lot while building a house: the city’s living-quarter restriction applies outside the park exception.5 Red Bud also restricts RV parking in front yards and street-abutting side yards, with the stated driveway exception.5

We could not confirm a separate Red Bud tiny-home occupancy rule, accessory-dwelling allowance or minimum dwelling size; ask the Code Administrator to evaluate the specific building and intended use.12 For a proposed new single-family dwelling, the city building-permit and inspection requirements still provide the starting point.111

Building a home in Red Bud: what are the steps, in order?

  1. Ask Red Bud Zoning and Planning to identify the parcel’s district and required zoning approvals for the proposed home and any subdivision.215
  2. Resolve sewer availability with the City Superintendent; if a private sewage system is proposed, obtain the city written permit and coordinate county health approval before construction.43
  3. Obtain the city residential building application and ask the Code Administrator which documents and charges apply to your project.191213
  4. Arrange the required residential inspections with at least 48 hours’ notice, including occupancy inspection.11
  5. At construction completion, the city enforcing office inspects the premises and issues or refuses a certificate of occupancy.13

What should you check before buying land in Red Bud?

For a new dwelling in a Red Bud residential district, the driveway must be concrete or asphalt; a driveway generally must stay at least 3 feet from the property line unless the Code Administrator gives written permission.20 Red Bud’s Code Administrator reviews flood-prone building sites, where new construction and substantial improvements need anchoring, flood-resistant materials and protected service equipment.21

Randolph County Health Department permits and inspects new water wells; ask that office and the city about a proposed private well inside Red Bud.16 For property outside city limits, use the Randolph County guide: county building and zoning administration covers unincorporated land and municipalities without their own zoning ordinance.2223

Watch-outs

  • An RV parked on a Red Bud driveway is not thereby authorized as living quarters; residential use is prohibited outside a camping trailer park.5
  • Red Bud’s 10,000-square-foot soil-absorption threshold is a private sewage permit condition, not a universal city minimum lot size.6
  • Illinois’s qualifying owner plumbing exemption still requires code compliance and inspection and does not remove all local plumbing permit requirements.78
