Do you need a building permit in Madison, SD?

Madison requires building permits unless the work is specifically exempt; the City lists new construction, additions, mobile-home placement or removal, decks, fences and various interior projects.1 Driveway construction is also on Madison’s list of work requiring a building permit unless exempt.9 Ask the Building Official to match the proposed work to the published exemption document before treating a small project as exempt.10 A building-permit exemption does not remove Madison’s floodplain development permit requirement for work in the floodplain, including placement of fill.10

Who issues building permits in Madison, and how do you apply?

Madison’s building-permit applications can be submitted online or completed and emailed to the Building Official; the City also publishes required plan-submittal information.6 The City directs building-permit questions to the Engineering Office, and Engineering & Community Development handles questions about the zoning documents.1011 Madison’s published building inspection stages are footing, foundation wall, framing, sheetrock and final, with additional or fewer inspections possible for particular projects.12 Ask the Building Official which inspection stages apply to the proposed construction before scheduling contractors or covering work.12

Does Madison have zoning, lot-size rules and setbacks?

Madison’s zoning ordinance applies throughout city limits, and the City publishes district regulations, an Official Zoning Map and conditional-use, rezoning and variance documents.213 In Madison’s AG Agricultural District, a farmstead or dwelling needs 20 acres per dwelling unit.7 In the RM Manufactured Housing Residential District, residential yards are generally 25 feet front, 5 feet side and 15 feet rear; one required front yard may be reduced to 20 feet, and side yards increase to 10 feet for buildings of 3 stories or more.14 Ask Engineering & Community Development to identify the parcel’s district and applicable zoning approval before choosing a home layout.11

How do septic permits work inside Madison?

Where public sanitary sewer is unavailable, Madison requires a written private sewage disposal permit signed by the superintendent before construction.154 The City application may require plans and specifications, carries a $10 permit and inspection fee, and requires at least 43,560 square feet of lot area for subsurface absorption.4 Notify the superintendent before underground portions are covered and when the system is ready for final inspection; the code provides for inspection within 48 hours after notice.16 State wastewater standards also apply, although a conventional individual system can meet state rules without submitting project plans to DANR for approval.517 That state exception does not waive Madison’s local permit.4

Can you live in an RV or tiny home in Madison?

We could not confirm Madison’s general rules for living in an RV, temporary camping, tiny-home occupancy or a separate accessory dwelling; ask Engineering & Community Development about the proposed use and the Building Official about the structure.1110 Madison’s manufactured-home rules do provide district-specific answers: AG permits Type I homes and conditionally allows Type II, while RM permits Type I and Type II and conditionally allows Type III homes and manufactured housing parks.8 Madison’s modular and manufactured-home minimum floor areas are structure-type standards, rather than a universal minimum for every dwelling.18 Manufactured housing parks require City sewer and water connections.8

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

  1. Confirm the parcel’s Madison zoning district with Engineering & Community Development and discuss any conditional-use, variance or rezoning application.1311
  2. Resolve public sewer availability; if unavailable, obtain the City’s private sewage disposal permit before construction.154
  3. Prepare the City’s required plan submittals and submit the building application online or by email to the Building Official.6
  4. Arrange the building inspections applicable to the project, including the published footing-through-final stages.12
  5. For qualifying homeowner electrical work, secure an approved state homeowner permit before starting; the licensure exemption does not waive electrical permitting or inspection.19

What should you check before buying land in Madison?

Use the Lake County guide for land outside Madison city limits: Lake County’s zoning ordinance applies to unincorporated areas, while Madison’s ordinance covers the city.32 For a Madison parcel, ask the Building Official about floodplain development approval even if the building work itself is exempt.10 We could not confirm a City private-well requirement; ask Engineering & Community Development before relying on a well.11 State water-right permitting depends on the proposed use, and a required water-right permit must be approved before drilling.20 Lake County’s soil figures are countywide: only 0.7% of soils are rated not limited for conventional drain fields, a reason to budget for site evaluation rather than assume septic is impossible.21

Watch-outs

  • We could not confirm a general Madison owner-builder exemption or certificate-of-occupancy requirement; ask the Building Official before planning construction or move-in.10
  • Madison allows private sewage disposal where public sewer is unavailable; an off-grid plan must still satisfy City approval and state wastewater standards.155
  • Madison’s AG dwelling acreage and RM yard dimensions are district-specific rules, not citywide defaults.714
