Does Town of Mooresville have zoning for RVs, tiny homes and setbacks?

Town of Mooresville has adopted a Unified Development Ordinance governing local zoning and land development inside incorporated limits.² The town Building Department enforces the zoning ordinance.⁷ We could not confirm Mooresville's rules for RV occupancy, temporary camping, tiny-home occupancy or accessory dwellings; ask the Building Department about the proposed use of the specific parcel before committing to a purchase.⁷ We also could not confirm district-specific minimum lot size, dwelling size, setbacks, lot coverage or height limits; ask the same office for the parcel's zoning district and applicable dimensional requirements.⁷ A building-permit requirement alone does not answer these proposed land-use questions: Mooresville's building rules and zoning ordinance are separate approvals to discuss with the town.¹²

How do sewer connections and septic permits work in Town of Mooresville?

Check sewer availability before planning a septic system in Mooresville: covered human-occupancy properties abutting a street, alley or right-of-way containing a public sanitary or combined sewer must connect at the owner's expense when that sewer is within 300 feet of the property line, within 30 days after availability.⁴ Indiana also prohibits onsite sewage disposal when sanitary sewer is available within a reasonable distance.⁵ Where a residential onsite system is applicable, Morgan County Health Department handles septic permitting and inspection.³ Morgan County's process starts with a soil test by a state-approved soil scientist, application documents and a site inspection, followed by fee payment and a signed permit.¹¹ The county must inspect the system before backfilling.¹² County residential septic fees include $200 for a trench system and $250 for a sand-lined system.¹³

What are the steps to build a home in Town of Mooresville?

1. Ask the Mooresville Building Department to confirm the proposed home's zoning compliance and the town building-permit requirements.⁷²
2. Establish whether sewer connection is required; if the home will use an onsite sewage system, arrange the Morgan County Health Department soil evaluation and septic-permit process.⁴¹¹
3. Submit the town form, lot-boundary sketch or plat, and construction plans and specifications; provide a state design release when the work requires one and pay the required fees.⁹
4. Arrange town building inspections and the county septic inspection before backfilling an onsite system.¹⁰¹²
5. Obtain the applicable full, partial or temporary certificate of occupancy from the Town Building Commissioner before occupying the covered structure.⁶

What should you check before buying land in Town of Mooresville?

For land outside town limits, use the Morgan County guide for the county's building-permit and zoning answers; Mooresville's Unified Development Ordinance is the town's local land-development rule.² Ask Mooresville's Building Department to confirm the parcel's jurisdiction and proposed development before relying on an address alone.⁷ We could not confirm the town's driveway-access rules or operative local floodplain requirements; ask the Building Department which approvals your site needs.⁷ Indiana DNR has jurisdiction over most floodway development activities, while local floodplain regulations may also apply.¹⁴ We could not confirm a Mooresville-specific residential well-permit requirement; ask Morgan County Health Department about the proposed well and drinking-water testing.¹⁵ Morgan County septic applications require a site evaluation and floodplain designation, so resolve those site conditions before assuming an onsite system can serve the home.¹⁶

Watch-outs

• Mooresville's sewer-connection rule can prevent a plan to use septic merely because you prefer an off-grid home.⁴⁵
• We could not confirm an owner-builder exemption from Mooresville building permits; the department's statement that a permit applicant need not be a licensed contractor does not establish a permit exemption.⁷¹
• Indiana onsite sewage rules do not allow drywells or cesspools as treatment methods.¹⁷
