Decks attached to a home in Des Plaines require a building permit regardless of size. Patios at grade may be permit-exempt below a threshold but still must comply with zoning, lot coverage, and floodplain rules.
Decks attached to a residence in Des Plaines require a building permit submitted to Community Development. Permit application requires a plot plan, framing/structural details, footing depth (must extend below 42-inch frost line), railing/guard heights (36 inches minimum, 42 inches over 30 inches above grade), and stair specifications. Decks above 30 inches require guard rails and graspable handrails on stairs. Detached low decks may have lighter requirements but still need zoning compliance. At-grade patios under a threshold (commonly 200 sq ft) often do not require a building permit but do count toward lot coverage and impervious-surface limits. Floodplain-area construction along the Des Plaines River faces additional elevation and permit requirements through the city's floodplain administrator. Pool decks have specific code requirements. Setbacks must be observed.
Unpermitted deck: $250-$1,000 plus required after-the-fact permit (typically double fee) or removal. Failed inspections: cannot finalize, may not be insured.
