Do you need a building permit in Spring Valley, IL?

Spring Valley requires a city building permit for principal and accessory buildings, porches, decks, carports, driveways, covered swimming pools and groundwater wells; the requirement also covers moving, enlarging and structurally altering covered structures.¹ A small project should therefore be checked against the city’s covered-project list rather than treated as automatically exempt.¹

Spring Valley’s published building-permit fee for new construction up to 5,000 square feet is $0.30 per square foot.⁶ Accessory buildings up to 150 square feet, driveway paving, swimming pools and demolition have a $20 flat fee.⁶ Structural alterations adding square footage have a $150 minimum fee.⁶ Ask the Building Inspector which fee category fits your plans before submitting the application.

Who issues building permits in Spring Valley?

Spring Valley’s building-permit application goes to the city zoning administrator, and the city’s official contact page lists a direct Building Inspector telephone number.⁹¹⁰ Start with the Building Inspector for your project and use the City Clerk’s Office for building-permit application forms.¹⁰¹¹

Spring Valley requires application information covering the site, intended use, zoning, survey, driveway, sewer and water, along with the relevant owner, designer and contractor details.⁹ New residential construction must comply with construction codes adopted by Spring Valley.¹² Ask the Building Inspector for the current code editions and the inspection schedule for your particular project; the city’s new-home requirements include contractor and applicable subcontractor certifications before occupancy.¹³

Does Spring Valley have zoning, and what about RVs or tiny homes?

Spring Valley has municipal zoning under its Land Development Code and a zoning map identifying city district classifications.²¹⁴ Ask the city zoning administrator to identify the parcel’s district and confirm the proposed residential use, minimum lot area, setbacks, height and lot coverage before committing to a design.

We could not confirm Spring Valley’s rules for living in an RV, temporary camping, tiny-home occupancy, manufactured homes or accessory dwellings; ask the Building Inspector about the specific dwelling and intended duration of occupancy. We also could not confirm a city minimum dwelling size or district dimensional schedule. A Spring Valley building cannot be occupied or reoccupied before the city issues its letter of occupancy, so a building permit alone does not authorize move-in.⁵

How do septic permits work inside Spring Valley?

For a Spring Valley site without municipal sewer, the city building-permit application must include a sewage-disposal plan approved by the city engineer and compliant with health regulations.⁴ Private sewage systems in Bureau County also require health department plan review, permits and inspections before use.³ The Bureau County Health Department permits and inspects septic systems and water wells; contact that office alongside the city when sewer service is unavailable.¹⁵

The septic application requires a soil report, complete system plans and the appropriate county fee.¹⁶ After approval, notify the health department at least 48 hours before work begins so inspection can occur before backfilling.¹⁶ Qualifying owners may install septic on owner-occupied property if all requirements are met; that allowance does not remove the application, plans, fee or inspection requirements.⁷

Building a home in Spring Valley: what steps come first?

1. Ask the city zoning administrator to confirm the parcel’s zoning classification and proposed use against Spring Valley’s zoning map.²¹⁴
2. Resolve utility plans: where municipal sewer or water is unavailable, obtain the required city-engineer approval for sewage disposal or an adequate, safe water supply.⁴
3. Submit the building-permit application to the zoning administrator with the required site and project information.⁹
4. For a subdivision lot, confirm city council approval of the plat and public-improvement plans before seeking the building permit.¹⁷
5. Complete the applicable construction certifications, then request the letter of occupancy in writing from the zoning administrator before moving in.¹³⁵

What should you check before buying land in Spring Valley?

Spring Valley requires a development permit from the Building Inspector before development in the floodplain, and the city cannot issue that permit until other required federal, state and local permits have been obtained.⁸ Ask the Building Inspector to resolve floodplain status before choosing the building location.

Water service also affects the application: where municipal water is unavailable, Spring Valley requires a city-engineer-approved plan certifying an adequate and safe supply.⁴ The Bureau County Health Department handles water-well permitting and inspections.¹⁵

For land outside Spring Valley’s city limits, use the Bureau County guide: Bureau County regulates construction in unincorporated areas and municipalities without their own zoning controls, while Spring Valley has municipal zoning.¹⁸² We could not confirm a general Spring Valley owner-builder exemption; ask the Building Inspector before planning to act as your own contractor.

Watch-outs

• Spring Valley’s septic self-installation allowance is conditional on owner occupancy and meeting all requirements; it is not a general home-building exemption.⁷
• Spring Valley has city zoning; we could not confirm RV or tiny-home occupancy rules, so ask the city Building Inspector before buying land for either use.²
• Spring Valley requires a city letter of occupancy before a building is occupied or reoccupied.⁵
