Do you need a building permit in Athol, ID?

Athol calls its city authorization a building-location permit, and requires it before construction or establishing a land use.1 The requirement covers placing, moving, enlarging and converting structures as well as new construction.1 Athol exempts fences no greater than 6 feet and qualifying non-habitable accessory storage structures with no more than 200 square feet of floor area, but applicable setbacks still apply.1

Athol requires a completed city application and a scaled plot plan showing the proposed development and existing improvements.8 The Administrator may inspect before, during or after construction and can stop noncompliant work.9 Before occupancy or beginning the authorized use, the owner must request Athol’s certificate of completion.10

Who handles Athol building-location permits and permit fees?

Contact Athol City Hall at (208) 683-2101 or [email protected] for the city’s application contact.11 Athol’s official website directs applicants to download and complete forms for submittal to the city.11 For zoning questions, the City Planner’s published phone is 208-755-7024 and email is [email protected].12

Athol’s adopted fee schedule lists residential site-disturbance, building-location and land-use permits at $100, and commercial, industrial and other nonresidential permits at $250.13 Ask City Hall which applications and charges apply to the proposed work.11 City building-location approval does not replace the Panhandle Health District septic permit, which also needs written Athol approval.4

Does Athol have zoning, and can you live in an RV or tiny home?

Athol divides land inside city limits into zoning districts.2 In Athol’s Residential (R) Zone, a single-family dwelling must contain at least 850 square feet of living space, with toilet, sink, bathing, cooking and food-preparation facilities and a bedroom area.3 A smaller proposed single-family tiny home would not meet that district’s stated living-space minimum.3

RV occupancy in Athol’s Residential (R) Zone is limited to 30 days in any 12-month period, with an exception for the parcel owner during construction or substantial remodeling under a valid permit.5 The RV must remain registered, serviceable and fully self-contained, and must be taken to an approved location to empty holding tanks; attached decks, additions, skirting, rentals and commercial use are prohibited.5 After construction ends or the permit expires, RV use returns to temporary or intermittent occupancy.5

How do septic permits work inside Athol?

Septic approval inside Athol involves both the city and Panhandle Health District.4 Panhandle Health District cannot issue an Athol subsurface sewage permit until the city sends written approval of the application and dwelling-equivalent allotment.4 Athol’s review also considers conflicts with the city water system.4

For site evaluation and septic records, contact Panhandle Health District’s Kootenai County Environmental Health office at (208) 415-5220 or [email protected].14 The district evaluates soil types at the proposed septic-system location and determines tank and drainfield sizing.14 Idaho requires an installation permit for installing, expanding, modifying or repairing a septic system unless a specified state exception applies.15 An individual system cannot receive wastewater before the required final installation inspection.16

Building a home in Athol: what are the steps, in order?

  1. Ask the Athol City Planner to identify the parcel’s zoning district and review the proposed use; Athol has its own zoning.122
  2. Resolve the city’s septic application approval and dwelling-equivalent review with Athol, then obtain the Panhandle Health District septic permit.4
  3. Submit Athol’s completed building-location application and scaled plot plan showing lot lines, known easements, septic facilities, utility lines, structures and distances.8
  4. Arrange the applicable electrical, plumbing and HVAC permits; Idaho’s trade-permit requirements depend on the work and administering jurisdiction.17
  5. Start city-authorized work within 6 months and complete it within 1 year; request any allowed extension before expiration.8
  6. Request Athol’s certificate of completion before occupancy, including review of parking, landscaping, stormwater and other applicable design standards.10

What should you check before buying land in Athol?

For land outside Athol city limits, use the Kootenai County guide: the county’s building-permit requirement applies to unincorporated land, while Athol requires its own city building-location approval.181 Inside Athol, ask City Hall about starting water service and confirm the water layout alongside the septic proposal, because the city reviews conflicts with its water system.114

A proposed private well requires an Idaho Department of Water Resources drilling permit before drilling and a licensed well driller; a domestic water-right exemption does not remove the drilling-permit requirement.7 Owners doing their own work on their own land may qualify for Idaho’s contractor-registration exemption if they do not intend to sell within 12 months, while Athol’s building-location permit requirement still applies.61

Watch-outs

  • Athol’s Residential (R) Zone home-size and RV rules are district-specific; ask the City Planner which district covers the parcel.3512
  • An Athol building-location permit expires if work does not start within 6 months or finish within 1 year; a single 1-year extension may be granted for good cause before expiration.8
  • We could not confirm Athol’s district lot-size and setback dimensions or a tiny-home-specific occupancy rule; ask the Athol City Planner before choosing a building footprint.12
