What this bill does

Amends the Illinois Municipal Code. Provides that a municipality shall provide for at least one residential zoning district in which detached single-family dwellings are permitted on lots with an area of not more than 2,500 square feet. Provides that a municipality may not require a minimum lot area of more than 2,500 square feet for detached single-family dwellings in any residential zoning district that permits detached single-family dwellings. Provides that, 8 months after the effective date of the amendatory Act, a municipality shall, on any lot located in a residential zoning district that permits single-family dwellings, allow (1) on an area of not more than 2,500 square feet, at least one detached single-family dwelling unit; (2) on any lot with an area of more than 2,500 square feet and not more than 5,000 square feet, up to 4 dwelling units; (3) on any lot with an area of more than 5,000 square feet and not more than 7,500 square feet, up to 6 dwelling units; and (4) on any lot with an area of more than 7,500 square feet, up to 8 dwelling units, including cottage clusters. Provides that a municipality must allow an existing principal residential structure to be converted to any middle-housing type if (1) the structure is not expanded by more than 50% of its existing floor area or more than 1,200 square feet, whichever is greater; and (2) the conversion complies with applicable building codes and preservation or landmark laws. Provides that municipalities may not adopt or enforce standards for bulk, lot area, yards, height, automobile parking, density, floor-area ratio, lot coverage, access, unit size, building separation, and design that (1) impose requirements on middle housing that are more restrictive than those applicable to detached single-family dwellings; (2) require automobile parking mandates for residential dwellings of less than 1,500 square feet and require automobile parking mandates no greater than specified requirements; and (3) require any form of discretionary review, unless the same review is required for detached single-family dwellings.
