Do you need a building permit in the Village of Davis Junction?

Davis Junction administers a village building permit application process, and every application must include complete drawings or plans.1 Ask the Village Building Department which building permit your proposed house, addition or accessory structure needs, and which code edition applies; we could not confirm a complete list of permit-triggering work.1

For privately funded construction, Illinois leaves building permit administration to the local government with jurisdiction.9 Outside village limits, consult the Ogle County guide: the county planning department administers unincorporated land and does not have jurisdiction inside incorporated cities or villages.5

Who handles building permits and inspections in the Village of Davis Junction?

Davis Junction names Lakeside Consultants as its Building Official, responsible for plan review and inspections effective July 2026.1 Call Village Hall for fee information; inspection requests go to Lakeside Consultants.1

The village asks applicants to allow up to 7 business days for standard building permit processing and up to 30 business days for new construction, remodels, pools and solar projects.1 A $100 plan review fee is due with each application except new construction projects, and inspection and resubmittal fees are additional.1 Inspection requests need the address, permit number, site contact name and phone, and at least 24-hour notice.1

Does the Village of Davis Junction have zoning and minimum lot sizes?

Davis Junction zoning distinguishes agricultural and residential uses rather than applying a single village-wide acreage requirement.2 In the village AG district, residential uses require 40 acres, agricultural uses require 5 acres, and both require a 300-foot lot width.2 Those AG figures should not be used as the minimum lot size for a parcel in a residential district.2

The village AG district caps residential height at 35 feet and agricultural height at 50 feet.6 For residential uses, the village height limits are 35 feet in R-1 and R-2 and 24 feet in R-3.3 Ask Village Hall to identify the parcel’s district and confirm setbacks and minimum dwelling size before ordering plans.1

How do septic permits work inside the Village of Davis Junction?

For a Davis Junction property using private sewage disposal, Ogle County Health Department permits new septic installations and repairs under county and Illinois private sewage rules.4 Illinois requires approval from IDPH or the applicable local authority before private sewage construction begins.10

For a new house, the septic installer submits the application, site plan, elevations sheet and maintenance agreement to Ogle County Health Department.11 After approval, the department inspects the system before it is covered.4 Treat septic approval and village building approval as separate tasks: the county health department handles the private sewage system, while the village Building Official handles plan review and building inspections.41

Can you live in an RV or tiny home in the Village of Davis Junction?

We could not confirm Davis Junction’s rules for residential RV occupancy, private-land camping or tiny-home occupancy; ask Village Hall about the proposed use before relying on an RV or small dwelling as housing.1 Give the office the parcel address, proposed duration and whether the unit will sit on wheels or a foundation.1

For a small dwelling proposed in the village AG district, the reviewed residential lot minimum remains 40 acres; a small floor plan does not establish an exception to that acreage requirement.2 Illinois’s conditional owner-occupant plumbing exemption also does not establish an exemption from local building permits or other construction requirements.7

Building a home in the Village of Davis Junction: what comes first?

Start with Village Hall to confirm the project’s village building permit requirements and obtain fee information, then prepare complete drawings or plans for the application.1 Identify the village zoning district before designing around lot dimensions or height limits, because the reviewed AG and residential requirements differ.23

If the property needs septic, arrange county health approval before private sewage construction and keep the system uncovered until the required inspection.104 Pay required plan review fees before village application processing, and arrange building inspections with the Village Building Official.1 For driveway design, Davis Junction requires compliance with its subdivision and development ordinance, Village Engineer requirements and adopted standards.12

Watch-outs

  • Davis Junction’s current Building Official is Lakeside Consultants; use the village’s current building page for inspection contacts.1
  • We could not confirm village RV occupancy, tiny-home, minimum dwelling size or floodplain approval requirements; ask Village Hall before committing to a purchase or housing plan.1
  • Illinois requires a permit before constructing, deepening, modifying or sealing a private well; ask Ogle County Health Department which approved authority handles your Davis Junction address.1314
