Read this before you act on anything below. This is my researched starting point for Kane County, IL, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesKane County, IL

Zoning & raw-land occupancy

Varies locallyKane County has a countywide zoning ordinance for unincorporated areas, with districts, setbacks, and lot rules; the Zoning Board of Appeals handles variances and special uses. Incorporated towns use their own separate zoning. source

Dwellings, tiny homes & RVs

Unclear - verifyThe county code specifically regulates trailer coach and mobile home parks, but no county text was found addressing full-time RV or tiny-home living outside such a park on unincorporated land. Ask the Zoning Administration office directly. source

Building permits & codes

Generally allowedKane County requires building permits for new construction on unincorporated land and has adopted current International and Illinois state codes. Agricultural buildings have limited exemptions that do not extend to residential use. source

Septic & composting toilets

Generally allowedPrivate sewage systems require a Kane County Health Department permit and must be installed by a licensed contractor, under authority delegated by the Illinois Department of Public Health. Composting toilets are not addressed in the county code found; confirm with KCHD. source

Greywater reuse

Unclear - verifyNo official Kane County or KCHD page specifically addressing greywater reuse was found. It may fall under adopted plumbing code or be handled case-by-case by KCHD; ask them directly.

Rainwater harvesting

Unclear - verifyNo county ordinance specifically permitting or restricting rainwater harvesting was found. County well-care guidance mentions keeping rainwater away from well casings, but that's a well-protection rule, not a general rainwater policy.

Private wells & water rights

Generally allowedNew or modified wells require a Kane County Health Department permit, and licensed well contractors must submit coliform test results to KCHD after completion.

Living disconnected from utilities

Unclear - verifyNo explicit county rule allows or bans full grid disconnection. A dwelling with a permitted well, permitted septic, and code-compliant construction appears workable off municipal utilities, but this is inference; confirm with Building & Zoning. source
