Evanston, Ill., City Code § 5 § 5-7-6

If selecting option B or option C to fulfill the inclusionary housing requirement, per Subsection 5-7-4 (E), the covered development's in-lieu fee must be calculated. In the case of option B, the unrounded remaining inclusionary housing requirement, or in the case of option C, the full, unrounded Inclusionary Housing Requirement is converted into a unit mix, as specified in Section 5-7-7 and as stipulated by the polices and procedures. (A)
Calculation.
1. In-lieu fees are as follows and are adjusted annually based on the Consumer Price Index, per the policies and procedures:
Studio | 1 BR | 2 BR | 3 BR | 4 BR
$405,000 | $481,000 | $711,000 | $1,070,000 | $1,429,000
2. If a fractional unit is required, the corresponding calculation uses the in-lieu fee for the most prevalent number of bedrooms. If the most prevalent is shared between multiple unit types, the unit type with the most bedrooms is used.
3. In-lieu fees are calculated by the Department as part of the inclusionary housing plan and building permit application process. In-lieu fees may be estimated by the Department separate from the above but are only estimates and subject to change.
(B) Payment. In-lieu fees are paid by the applicant as part of the permit application process and before being granted a building permit.
