Do you need a building permit in Kokomo, IN?

Kokomo requires a general building permit before constructing a new building, adding to an existing building, making alterations or major repairs, or changing a building’s use.¹ Obtain the construction or alteration permit in advance through the Department of Engineering, Traffic and Inspection Services; the city code names the City Civil Engineer as the general building permit issuer.⁷ Kokomo also incorporates Indiana building, residential, plumbing, electrical, mechanical, energy, swimming-pool and fire-prevention rules into its building chapter.⁸ Before treating a small project as exempt, describe the proposed work to Inspection Services and ask which building or electrical approvals apply.⁹

Who is the Kokomo building department, and how do you reach it?

The City of Kokomo Inspection Services Department issues building permits, and the permit office is on the first floor of City Hall.⁹ Call (765) 456-7362 or email [email protected] to discuss a city building permit application.⁹ For city zoning questions, contact the Kokomo - Howard County Plan Commission at 765-456-2330; the municipal site lists the City of Kokomo office at 224 N. Main St. Kokomo, Indiana 46901.¹⁰ The shared commission oversees both city and county planning bodies, so identify the property as inside Kokomo when requesting zoning guidance.¹⁰ Septic construction or repair approval remains a separate matter for Howard County Environmental Health.³

Does Kokomo have zoning, and can you live in an RV or tiny home?

Kokomo has adopted its own zoning ordinance by reference, and copies are available from the City Clerk and Kokomo Plan Commission.² Ask the city planning office for the parcel’s zoning district and the applicable use and dimensional provisions before choosing a house design.² We could not confirm Kokomo’s specific tiny-home, accessory-dwelling, temporary-camping, minimum dwelling size, minimum lot size or setback rules; take those questions to the Kokomo Plan Commission.¹⁰ We also could not confirm a complete answer for living in an RV on a private Kokomo lot; ask the city planning office about the proposed occupancy before buying land for that purpose.¹⁰ A city zoning inquiry does not replace the separate septic construction or repair approval from Environmental Health.³

How do septic permits work inside Kokomo?

A Kokomo dwelling that will not connect to sanitary sewer needs a written residential on-site sewage construction permit signed by the health officer.¹¹ Howard County Environmental Health requires a permit before septic construction or repair, and any septic work needs prior approval.³ The department requires a soil test in all cases, with soil type and bedroom count affecting system size.³ Howard County’s soil rating is a useful caution: only 0.8% of county soils rate “not limited” for a conventional drain field, which calls for parcel-specific evaluation and may require an engineered system rather than making septic impossible.¹² A homeowner installing septic on their own Howard County property may be exempt from installer license fees and insurance, but must pass the required examination and meet septic permit requirements; the exemption excludes commercial interests.⁶

What are the steps to building a home in Kokomo?

1. Ask the Kokomo Plan Commission for the city zoning ordinance and confirm the proposed residential use and parcel requirements.²
2. If sanitary sewer will not serve the home, arrange a soil test and obtain Environmental Health’s septic approval before septic construction.¹¹³
3. Obtain the city general building permit before starting the home; contact Inspection Services for the application requirements and any related building approvals.¹⁹
4. Coordinate the inspections necessary to enforce Kokomo’s building chapter with the City Civil Engineer or delegate.⁴
5. Obtain the city certificate of occupancy before using or occupying a structure covered by the building chapter.⁵

What should you check before buying land in Kokomo?

Before buying a Kokomo parcel, ask the Kokomo Plan Commission about city zoning and obtain the ordinance that applies to the intended use.² We could not confirm Kokomo’s operative sewer-connection distance rule, private-well permit rule, driveway approval triggers or complete floodplain development requirements; ask Inspection Services to identify the responsible city office for each parcel question.⁹ If the parcel needs septic, contact Howard County Environmental Health about the soil test and system approval before committing to a house layout.³ For land outside Kokomo’s city planning jurisdiction, consult the Howard County guide: the county zoning ordinance governs unincorporated territory outside established city and town planning jurisdictions.¹³

Watch-outs

• We could not confirm a general Kokomo owner-builder exemption from building permits; ask Inspection Services before planning to build without a contractor.⁹
• Kokomo’s certificate of occupancy requirement applies before use or occupancy of structures covered by its building chapter.⁵
• An owner-installed septic exemption covers installer license fees and insurance, not the septic construction permit or required examination.⁶
