Does Sleepy Hollow, Illinois have zoning?

Yes. The Village of Sleepy Hollow administers its own zoning through a village zoning officer, and questions about zoning go to that officer2. Kane County's zoning ordinance covers only unincorporated land, so it does not govern a lot inside Sleepy Hollow7.

The full zoning text was not available online when we looked, and the village says only the code book at Village Hall is authoritative2. We could not confirm how the zoning rules treat tiny homes, accessory dwellings or manufactured homes, so ask Village Hall before you buy8.

Do you need a building permit in Sleepy Hollow, and who issues it?

Yes. A construction permit from the village is required for any remodeling, new homes, re-roofing and concrete work1. The village building code official administers the village building codes5. The general residential building permit application is available at Village Hall or can be downloaded and emailed to the village9.

The village asks residents to check with Village Hall before starting a project1. We could not confirm the review steps, timelines, fees, inspection rules or whether an owner-builder exemption exists, so ask the village before you plan a schedule.

How do septic permits work inside Sleepy Hollow?

Most Sleepy Hollow homes use septic systems, and the permit comes from the Kane County Health Department rather than the village3. A Kane County Health Department septic permit is required, and the work must be done by a licensed septic contractor, even for a homeowner on their own property6.

A sewered area exists on the east side of the village, and a new home there generally must connect to public sewer unless the connection needs a pipe larger than 4 inches or creates an undue hardship10. The county health department also does not perform septic inspections for home sales or mortgage transactions11.

Can you live in an RV or tiny home in Sleepy Hollow?

Not in an RV. The village prohibits occupancy of recreational vehicles on residential property4. Storage is limited to one RV or boat, not over 24 feet, on a paved driveway4.

We could not confirm whether the village allows tiny homes, so ask the zoning officer through Village Hall before buying with a tiny home in mind8.

Building a home in Sleepy Hollow: the steps, in order

  1. Call Village Hall to confirm the zoning for the lot and what your project needs2.
  2. Find out whether the lot is on public sewer; if not, contact the Kane County Health Department about a soil evaluation and septic permit6.
  3. Submit the village's general residential building permit application9.
  4. Hire a licensed septic contractor for any septic work6.
  5. Ask the village building code official about inspections, which we could not confirm5.

What stays with Kane County, and what to check before you buy?

Septic permits for Sleepy Hollow addresses come from the Kane County Health Department3. Kane County's own building permit and zoning rules apply only to unincorporated land; see the Kane County page for land outside the village12.

We could not confirm whether private wells are allowed in the village, which operates a water system serving most residents, so ask Village Hall8.

Watch-outs

  • The village's published page is only a summary of its ordinances, and only the code book at Village Hall is authoritative2.
  • Septic work inside the village needs a county permit and a licensed contractor even if you are the owner6.
