Before submission

What to prepare

Online application and supporting project documents. The forms library includes accessory-structure and detached-garage resources, owner authorization and standard details. [2]

These are document categories. The official application and your project determine the exact requirements.

Fees and review time

Ask Village of Downers Grove Community Development for the current fees and review timing for your scope. Confirm when payment is due and which inspections apply before you book construction.

before you hire.

Lay out your project, organize required approvals, and discuss expected costs with Permibot before you speak to a contractor.

Project-specific requirements and planning tools are available in your workspace. The permit office makes the approval decision.

Read the film's visual description

A homeowner imagines a deck and pergola. Property boundaries and an easement complicate the sketch. Permibot locates the parcel, helps reposition the project and assembles a site plan and document packet. The homeowner connects with a builder. The application is reviewed, corrected and resubmitted before approval. A permit is posted; construction follows and the finished backyard is revealed.

This is a general illustration of the planning process, not a recorded permit case in Downers Grove.
