πŸ—οΈ Accessory Structures

Thinking about an ADU, shed, or garage conversion? Local rules on accessory structures have changed rapidly in recent years, especially in California.

ADU Permits

Heavy Restrictions

Naperville's Zoning Ordinance (Title 6 of the Municipal Code) does not define 'accessory dwelling unit' as a permitted use category. A second self-contained dwelling on a single-family lot is generally allowed only where the underlying district permits two-family or multi-family use (R2 or higher), or where the Planning and Zoning Commission and City Council approve a variance, conditional use, or planned unit development. Illinois has no statewide ADU preemption statute; under the Illinois Municipal Code (65 ILCS 5/) and home-rule authority (Ill. Const. Art. VII Sec. 6), Naperville retains full zoning discretion and has historically applied it strictly.

Code Authority: Naperville Zoning Ord. Title 6Permitted Districts: R2 and higher (by right); R1/R1A by variance

ADU Rental Restrictions

Heavy Restrictions

Naperville bans short-term residential rentals citywide under Title 3 Chapter 18 of the Municipal Code (added by Ordinance 20-087, effective September 1, 2020). Stays under 30 days for compensation are unlawful regardless of platform (Airbnb, Vrbo, Booking.com). Long-term rentals (30 days or more) of accessory dwelling units are allowed where the underlying zoning permits two-family or higher use and any PZC conditions are satisfied; landlords should register with Naperville Finance for utility handling. Tenancies are governed by the Illinois Landlord and Tenant Act (765 ILCS 705/) and the Security Deposit Return Act (765 ILCS 710/). Illinois prohibits rent control under 50 ILCS 825/.

Short-Term Rental: Banned (Title 3 Ch. 18; Ord. 20-087)STR Fine - First: $1,000 per day

ADU Impact Fees

Some Restrictions

Naperville imposes one of Illinois's best-known development exactions through its land-cash donation ordinance (originally Ord. 72-20, upheld in Krughoff v. City of Naperville, 354 N.E.2d 489 (Ill. App. 1976), aff'd 68 Ill. 2d 352), now codified through Title 7 subdivision and Title 10 administrative fee provisions. New residential subdivisions must dedicate land (8.6 acres per 1,000 projected residents under the 2001 amendment) or pay cash in lieu for schools and parks. Impact fees on a single ADU added to an existing lot are typically limited to building permit and utility connection charges; the land-cash exaction applies primarily at subdivision approval, not at individual building permit.

Land-Cash Authority: Krughoff v. Naperville (1976); Naperville Code 7-3-5:12.7Current Dedication Standard: 8.6 acres/1,000 residents (2001 amendment)

ADU Owner Occupancy

Some Restrictions

Naperville's Zoning Ordinance Title 6 does not contain an explicit owner-occupancy definition for accessory dwellings because 'ADU' is not a defined use category. Where a second dwelling has been approved through a variance or conditional use, the Planning and Zoning Commission and City Council may attach an owner-occupancy condition. Illinois has no statewide preemption of municipal owner-occupancy rules; home-rule authority under Article VII Section 6 of the Illinois Constitution preserves Naperville's discretion. Naperville's short-term rental ban (Title 3 Chapter 18) compounds these limits.

Code Authority: Title 6 zoning + PZC conditionsRental Registration: Voluntary (Naperville Finance Dept., utility-based)

Carport Rules

πŸ– Outdoor Cooking

BBQ & Propane Rules

Some Restrictions

Naperville has not adopted a separate municipal BBQ ordinance; outdoor cooking is governed primarily by the Illinois Fire Code (Office of the State Fire Marshal adoption of NFPA 1 under 41 Ill. Adm. Code 100) and the IFC provisions referenced through Naperville's Title 5 Chapter 1 (Building Codes) and fire-prevention provisions enforced by the Naperville Fire Department Community Risk Reduction Division. The controlling rule for multifamily and combustible balconies is IFC/NFPA Section 308.1.4: charcoal burners and open-flame cooking devices may not be operated on combustible balconies or within 10 feet of combustible construction, with exceptions for one- and two-family dwellings, sprinklered buildings, and LP-gas containers of 2.5-pound water capacity or less.

Primary Standard: NFPA 1 Sec. 10.11 / IFC 308.1.4State Authority: 41 Ill. Adm. Code 100 (IL Fire Code)

Smoker Rules

Some Restrictions

Outdoor smokers (charcoal-fueled, wood-pellet, or propane-assisted) are treated as open-flame cooking devices under NFPA 1 Section 10.11 and IFC Section 308.1.4, the same standard applied to BBQ grills. Naperville has no smoker-specific ordinance. Single-family and two-family yards may use smokers with normal precautions; combustible balconies of non-sprinklered multifamily buildings are off-limits within 10 feet of construction. Naperville's general 50-foot setback for cooking fires from structures (15 feet if in an approved container) and smoke nuisance prohibitions apply.

Governing Standard: NFPA 1 Sec. 10.11 / IFC 308.1.4Local Authority: Naperville Title 5 Ch. 1 (Building Codes)

Heavy Restrictions

Inflatable Display Rules

Some Restrictions

Naperville's sign ordinance (Title 6 Chapter 16) treats commercial inflatable displays β€” cold-air balloons, dancing 'air-dancer' figures, and feather banners at businesses β€” as temporary signs requiring a permit, with a maximum of four weeks per calendar year per business in full-week increments. Residential holiday inflatables (snowmen, Santas, Halloween ghosts) on a private single-family yard are not regulated as signs because they do not advertise commercial products or services. Placement should observe sight-distance triangles at corner lots and stay out of the public right-of-way.

Residential Treatment: Not a sign (no permit required)Commercial Treatment: Temporary sign under Title 6 Ch. 16

Holiday Light Rules

Few Restrictions

Naperville has no ordinance setting a specific seasonal start or removal date for residential holiday lights. Decorative holiday lighting on a single-family or two-family home is generally treated as accessory to the principal dwelling and is not regulated as a 'sign' under Naperville Zoning Ordinance Title 6 Chapter 16 (Signs). The community embraces seasonal lighting β€” Naperville's annual Riverwalk and downtown Hometown Holidays celebrations spotlight residential and commercial displays. Reasonable use is expected; persistent year-round commercial-style displays creating glare or hazards may be addressed under general nuisance provisions.

Seasonal Time Limit: None in city codeSign Code Treatment: Not regulated as sign (Title 6 Ch. 16)

Lawn Ornament Rules

Few Restrictions

Naperville does not regulate ordinary lawn ornaments (statuary, garden gnomes, flamingos, deer, religious figures, flag poles, bird baths) under Title 6 (Zoning) or general code, provided the items remain on private property, do not obstruct sight-distance triangles at corner lots, do not encroach into the public right-of-way, and do not constitute commercial signs.
