Building permits, zoning and septic rules in Pocatello, Idaho

Pocatello, Idaho requires building permits from the City Building Department before regulated construction begins, including fence installation.1 Pocatello has its own zoning, so a parcel in Bannock County must be evaluated under the city rules when it lies inside city limits.2 Pocatello decides when private septic is eligible, while the local health district issues septic permits.3 Permanent residence in an RV is prohibited in Pocatello.4

Do you need a building permit in Pocatello, ID?

Pocatello requires a City Building Department permit before construction activity regulated by the building code, residential code or city code begins; fence installation also requires a permit.1 Pocatello has adopted the 2018 International Building Code and residential, energy, existing-building and fire codes with amendments.8

Pocatello allows an owner or contract purchaser to obtain a construction permit for a single-family home that is or will be the person’s primary residence without a contractor’s license, subject to the city conditions.5 The owner-builder route is limited to a permit in any 3-year period beginning with the certificate-of-occupancy date for the qualifying residence; it does not remove the building-permit requirement.5

Who issues Pocatello building permits, and how do you apply?

The Pocatello Building Department is the city counter for building permits; the city directs applicants to its eTRAKiT portal.19 Use the Building Department’s online tools to schedule or cancel inspections and search active, closed or expired building-permit records by address.9

Pocatello Planning & Development Services separately directs land-use applications through eTRAKiT, so discuss the proposed use and zoning with Planning before finalizing a building design.102 Private septic approval remains a separate health-district matter even though the city controls building permits and land use.3 For newly constructed premises, additions and major remodeling, the city requires a certificate of occupancy before establishing the ordinary utility account.11

Does Pocatello have zoning, lot-size rules and setbacks?

Pocatello has city zoning covering land uses, development standards and special uses.2 In Pocatello’s Residential Estate (RE) district, the single-family minimum lot size is 15,000 square feet; that figure is specific to RE, not a citywide minimum.7 RE single-family setbacks are 25 feet at the front, 10 feet at the side and 20 feet at the rear, with separate garage and street-facing rules.12 RE buildings have a maximum height of 35 feet, subject to the dimensional table’s exceptions.13

Ask Pocatello Planning & Development Services to identify the parcel’s district and review the proposed footprint before relying on those RE dimensions.102 Pocatello also regulates subdivision plats, with preliminary-plat decisions involving the Planning and Zoning Commission and final-plat and short-plat decisions assigned to the City Council.14

How do septic permits and off-grid utilities work in Pocatello?

Pocatello requires City water use when a water line is within 300 feet of the applicable property line and the property abuts or has permanent access to the relevant street, alley or right-of-way.15 Public sewer connection is required within 90 days after official notice when the sewer line is within 300 feet and sanitary facilities are required.15

Private septic in Pocatello is only potentially allowed when the Director determines sewer connection is impractical: the minimum parcel is 1 acre with municipal water or 2.5 acres with private water.16 Eligibility under the city rule does not replace a septic permit from Southeastern Idaho Public Health.317 The health district requests a completed application, plot plan and deed or tax notice, and requires an onsite evaluation for all applications.17 Idaho also requires septic installation inspections under the statewide rules.18

Can you live in an RV or tiny home in Pocatello?

Pocatello prohibits using recreational vehicles as permanent residences and allows temporary living quarters only while occupants are engaged in recreational activities.4 Pocatello’s temporary-use provision therefore does not establish permission to live in an RV while building a house.19

A small accessory dwelling has a separate route: Pocatello conditionally permits accessory dwellings in residential, commercial and mixed-use districts, accessory to a primary single-family dwelling on a lot meeting the district minimum.6 The accessory dwelling is limited to 750 square feet and 1 bedroom or sleeping room, and either the primary or accessory unit must be owner occupied through a recorded deed restriction.6 We could not confirm a distinct tiny-home occupancy rule or general minimum dwelling floor area; ask Pocatello Planning & Development Services and the Building Department to classify the proposed home before buying it.

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

  1. Identify the parcel’s city zoning district and discuss the proposed use, lot dimensions and setbacks with Pocatello Planning & Development Services.210
  2. Resolve water and sewer connection requirements; if private septic is eligible, obtain health-district septic approval separately.153
  3. Apply for the city building permit through eTRAKiT before regulated work begins; discuss applicable electrical, plumbing and HVAC permits with the Building Department because trade-permit jurisdiction varies by location.9120
  4. Obtain a floodplain development permit from the city Floodplain Administrator, the City Engineer or designee before any development in a Special Flood Hazard Area.2122
  5. Schedule city inspections through the online tools and secure the certificate of occupancy needed to establish the utility account for new construction.911

What should you check before buying land in Pocatello?

Pocatello’s water and sewer connection rules can determine whether a proposed off-grid layout is feasible, so resolve utility proximity and private-septic eligibility before committing to a parcel.1516 A private well still requires an Idaho Department of Water Resources drilling permit before drilling, and the domestic water-right exemption does not eliminate that requirement.23 For an approach onto a state highway, an Idaho Transportation Department encroachment permit is required before work in the highway right-of-way.24

For land outside Pocatello city limits, use the Bannock County guide for the county’s building-permit answer; county zoning powers apply to unincorporated land.2526 Within Pocatello, keep the city’s building and zoning decisions separate from health-district septic approval and state well requirements.12323

Watch-outs

  • Pocatello’s fence-permit requirement is explicit; do not assume a small fence is exempt from a city building permit.1
  • An RV’s temporary recreational use allowance does not authorize permanent RV residence in Pocatello.4
  • We could not confirm Pocatello’s general lot-coverage percentage or a distinct tiny-home occupancy rule; ask Planning & Development Services about the specific parcel and design.10
  • Pocatello requires a floodplain development permit before development in a Special Flood Hazard Area.21
