Naperville Inclusionary Zoning Rules for Affordable Units

Land Use and Zoning Illinois 4 Minutes Read · published February 21, 2026 Flag of Illinois

In Naperville, Illinois, inclusionary zoning — local requirements that a portion of new housing be affordable — is addressed through the city’s zoning and planning framework and related development agreements. This guide explains where such requirements would appear in Naperville practice, who enforces them, how developers and residents can comply or report concerns, and what official documents or applications to consult. Because specific inclusionary zoning ordinances vary by municipality, the city code and Planning & Building resources are the primary sources for Naperville policy and procedures.

What is inclusionary zoning and how it applies in Naperville

Inclusionary zoning typically requires or incentivizes developers to provide a share of new units at below-market rents or sale prices, often tied to area median income (AMI), unit size, or building type. In Naperville, such provisions would be implemented through the municipal zoning code, planned unit development (PUD) conditions, development agreements, or density/bonus programs administered by the Planning & Building Department. For the controlling municipal code text and zoning procedures consult the city zoning code and planning pages directly via the official links below Naperville Municipal Code[1] and the Planning & Building Department site Planning & Building[2].

Inclusionary requirements in Naperville are most often set by development agreement terms rather than a single citywide ordinance.

How requirements are adopted and implemented

  • Zoning amendments and PUD approvals: inclusionary clauses can be attached as conditions to approvals and recorded in development agreements.
  • Developer obligations: agreements specify number of affordable units, eligibility criteria, and monitoring requirements.
  • Alternatives: in-lieu fees or off-site unit provisions may be allowed where specified in the agreement or ordinance.
  • Monitoring and affordability periods: deed restrictions or covenants often establish minimum affordability durations and resale controls when included.

Penalties & Enforcement

Enforcement in Naperville would be handled by the city’s Planning & Building Department and Code Enforcement, supported by recorded development agreements and deed restrictions. Specific monetary fines or escalation schedules for failure to provide required affordable units are not specified on the cited municipal pages and typically appear in individual development agreements or specific ordinance language when adopted for a project Naperville Municipal Code[1].

  • Fines: not specified on the cited page for a citywide inclusionary zoning ordinance; may be defined in a project development agreement or a specific ordinance.
  • Escalation (first/repeat/continuing offences): not specified on the cited page.
  • Non-monetary sanctions: enforcement commonly includes stop-work orders, requirement to complete mitigation (build units or pay fee), recording of corrective covenants, or pursuing compliance through court action.
  • Enforcer and complaint pathway: Planning & Building Department and Code Enforcement receive compliance reports and administer permits; use the city Planning & Building contact and complaint pages for official submissions Planning & Building[2].
  • Appeal and review routes: appeals related to zoning decisions are processed per the municipal code and the City’s boards (for example, Zoning Board of Appeals or City Council); specific time limits for appeals are not specified on the cited planning pages.
  • Defences and discretion: the city may allow variances, modifications, or negotiated alternatives (in-lieu fees, off-site units) through formal approvals; availability depends on code text or the negotiated development agreement.
If an inclusionary requirement is proposed for a project, review the recorded development agreement and recorded covenants for exact obligations.

Applications & Forms

Where inclusionary requirements exist for a specific development, the required forms and submittals are usually part of the zoning application, PUD application, or building permit packet; the city’s Planning & Building pages list permit and application procedures but do not publish a single universal inclusionary zoning form. For project-specific obligations check development agreement exhibits and the zoning application materials on the Planning & Building site Planning & Building[2].

How developers comply — practical steps

  • Early engagement: meet with Planning & Building during pre-application to identify any affordable unit obligations.
  • Include compliance language: ensure development agreements and plat notes reflect the unit counts, AMI targets, and monitoring terms.
  • Budget for alternatives: plan for in-lieu fees or off-site provision if allowed.
  • Record restrictions: file deed restrictions or covenants with the county recorder to secure affordability periods.
