The State of Indiana requires a State Plan Review based on qualifying parameters. Generally, certain types of structures, detached structures 500 square feet or less, attached structures 300 square feet or less, plumbing work that does not exceed 5 fixture units, and projects with less than 100 linear feet of non load-bearing partitions, can usually be handled with just a local Plan Review.
Local Plan Review will include submission to other departments as necessary. Reviews by other departments such as Area Plan Commission, Engineering, and Health may require additional details and fees. It is the applicant’s responsibility to ensure these requirements.
