Do you need a building permit in Southport, IN?

Southport requires a building permit under rules adopted by the city Board of Public Works for work covered by its building standards.1 Southport incorporates Indiana building rules by reference, including later amendments with their stated effective dates.9 The city’s residential structural building permit fee is $80 plus $0.05 per square foot; electrical, mechanical, plumbing and site-development building permit fees use the same base-and-area formula.6 Ask the Clerk-Treasurer which application and trade categories your project needs before budgeting the total building permit cost.2

Who handles Southport building permit applications?

Southport’s Clerk-Treasurer processes building permit applications, and completed, signed forms may be emailed, mailed or delivered to the office during business hours.2 Contact the office at (317) 786-3585 or [email protected]; the listed address is 137 Worman Street Southport, Indiana 46227.2 Southport’s Building Commissioner or designee reviews building permit applications for code compliance before issuance, so ask the intake office to route technical questions to that role.10 Southport’s Building Commissioner also arranges inspections needed to establish compliance after a building permit is issued.11

Does Southport have zoning, and what about RVs and tiny homes?

Southport has its own zoning-appeal and rezoning functions, and its Board of Zoning Appeals hears variance petitions.3 We could not confirm Southport’s current district schedule for minimum lot size, setbacks, lot coverage, building height or minimum dwelling size; ask the Clerk-Treasurer to connect you with the city zoning contact for the parcel.32 We also could not confirm Southport’s rules for residential RV occupancy, temporary camping, tiny homes, manufactured homes or accessory dwellings; ask the city zoning contact about the exact proposed use before buying.32

How do septic permits work inside Southport?

Marion County Public Health Department handles onsite sewage systems in Southport, and new septic construction or repairs require a septic permit.47 Septic installers must be certified by the Indiana Onsite Wastewater Professional Association, and systems must meet state and Marion County health standards.7 Contact the Onsite Sewage Systems Program at 317.221.2266 to discuss the site and application before committing to a septic layout.12 We could not confirm the septic inspection stages or whether an off-grid sanitation proposal would be approved in Southport; ask the health program about sanitation approval and the city about the proposed residential use.123

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

  1. Ask Southport’s city zoning contact about the proposed residential use and any needed variance; begin with the Clerk-Treasurer for routing.32
  2. If using septic or a private well, discuss the health approvals with Marion County Public Health before construction.78
  3. Submit the signed building permit application through the Clerk-Treasurer for Building Commissioner review.210
  4. Arrange the building inspections required by the Building Commissioner as work proceeds.11
  5. Request a final inspection and receive the required certificate of occupancy before allowing the covered building to be occupied.5

What stays with Marion County, and what should Southport buyers check?

Private-well construction remains a Marion County Public Health responsibility: before beginning a well that does not serve a municipality or public utility, a licensed driller must obtain a Health Officer-signed well permit; the stated fee is $50.8 Southport’s building review includes flood safety, and projects within the 100-year floodplain are reviewed for an Indiana Department of Natural Resources permit or letter of authorization.13 We could not confirm Southport’s public-water or sanitary-sewer connection triggers or driveway approval rules; ask the Clerk-Treasurer to route those parcel questions before purchase.2 For land outside Southport city limits, consult the Marion County guide; Southport’s building standards apply inside the city.9

Watch-outs

  • We could not confirm a Southport owner-builder exemption; ask the Building Commissioner through the Clerk-Treasurer before assuming you can pull each building permit yourself.2
  • Southport may charge re-inspection fees when work is incomplete or not ready for inspection.11
  • Southport requires the permit holder to obtain the applicable certificate of occupancy before occupancy of covered buildings.5
