Septic rules in Ionia County

Ionia County has its own health department. Its water and sewage page says it permits all onsite sewage systems, including repairs, and describes a soil and site evaluation after the application and fee are paid. The department offers a loan evaluation, an inspection of existing water supply and sewage systems for real estate transactions or refinancing of private residences only, with a written report after a request form and fees.

No time-of-sale mandate appears in the published pages, which is not the same as the county saying there is none. A sanitary code, a fee schedule, installer licensing and distance requirements are all absent from the pages the county publishes. Phone and on-site consultations are available on request, with environmental health open Monday through Friday, 8 to 4, at 616-527-5341, and the page links the Septic Replacement Loan Program. If you are buying in Ionia County, ask the office whether the loan evaluation is something a lender will want, and what it costs this year.

Ionia, with 12,950 residents and 78.5 percent of homes built before 1980, is the Ionia city here. The buying guide lists what to ask for.
