Zoning, building permits and septic rules in Willowick, Ohio

In Willowick, Ohio, the city's Building Department issues zoning permits, while building permits required by the Ohio Residential Code are administered by the Lake County Building Department1. Willowick prohibits living in a recreational vehicle in residential areas2. Septic permits for Lake County come from the Lake County General Health District, though we could not confirm how that applies to a sewered city lot3.

Do you need a building permit in Willowick, Ohio?

Yes for most work, but the permit does not come from the city. Willowick's Building Department states that building permits required by the Ohio Building Code and the Residential Code of Ohio are administered by the Lake County Building Department1. The city has adopted the Residential Code of Ohio for construction inside city limits7, and Lake County treats residential building permits as required8.

The city adds its own layer: zoning permits from the city may be required before the county issues a building permit1. A certificate of occupancy is required when a building changes owner or tenant, and the fee for a new building certificate is $509. The city also lists a $250 fee for a new single-unit building's first 1,100 square feet, plus $10 for each additional 100 square feet10. We could not confirm from the city's code whether a general new-building permit is also collected by the city, so ask the Building Department before you pay anyone.

Who handles building permits and zoning in Willowick, and how do you reach them?

Two offices split the work. The City of Willowick Building Department, at 31230 Vine Street, issues zoning permits, reviews plans, runs point-of-sale inspections and registers contractors1. The Lake County Building Department in Painesville issues the building permits required under the Residential Code of Ohio1. The county's page confirms that the department is certified by the State of Ohio to provide plan reviews and inspections11.

Contractors working in Willowick must be registered with the city, even if already registered with the county1. Homeowners can perform specified electrical, HVAC, hydronic and fire-suppression work on a one-, two- or three-family dwelling after signing a waiver under the county process12.

Does Willowick have zoning, and what does it mean for RVs, lot size and height?

Yes. The city issues its own zoning permits1. In a Single Family District, a dwelling may house one family for each 7,500 square feet on an interior lot, or each 6,000 square feet on a corner lot4. Buildings in that district are limited to two and one-half stories or 35 feet, with a higher limit for churches, schools and libraries5.

Willowick prohibits using a recreational vehicle for living or housekeeping in residential areas, and loading or unloading is allowed for no more than 48 hours2. We could not confirm Willowick rules on tiny homes, accessory dwellings or minimum dwelling size; call the Building Department.

How do septic permits work in Willowick, Ohio?

Ohio requires an installation or alteration permit from the board of health for a new or replacement sewage treatment system3. In Lake County, the Lake County General Health District runs that program13. Where a public sewer is accessible and available, state rules call for connecting to it14.

Inside Willowick, a house-sewer connection, repair or alteration must be inspected by the city's Building Inspector before the work is covered15. We could not confirm whether any lot in Willowick is allowed a private septic system, so ask the Lake County General Health District16.

Building a home in Willowick: the steps, in order

  1. Call the City of Willowick Building Department to confirm the zoning district, lot size and setbacks for your lot1.
  2. Obtain the city zoning permit, which may be required before the county permit1.
  3. Submit plans to the Lake County Building Department for a building permit1.
  4. If the lot is in a special flood hazard area, obtain a floodplain development permit from the Floodplain Administrator before work starts6.
  5. Confirm sewer or septic with the Lake County General Health District and the Building Department16.
  6. Request a certificate of occupancy when the work is complete9.

What stays with Lake County, and what to check before you buy in Willowick?

Building permits and septic permits stay with Lake County offices. For land outside Willowick's city limits, see the Lake County page. Lake County's effective property tax rate is 1.7%17, with a median bill of $3,405 a year18. Willowick also requires a point-of-sale inspection when you sell, including a sewer dye test, sidewalk and apron inspection and a fire safety inspection1.

Watch-outs

  • Zoning permits come from the city and building permits come from the county, so a zoning approval alone does not authorize construction1.
  • Recreational vehicles may not be used for living in Willowick's residential areas2.
  • We could not confirm Willowick's rules on private septic systems, wells, driveways or tiny homes; ask the Building Department and the Lake County General Health District16.
