Written by a named researcher (Kjel > Jones, Rexburg, ID — not a builder and not a general contractor), with every > load-bearing fact tied to a dated document. > Phone: +1 (208) 656-1745. Key verified facts (as of 2026-08-14): - Fremont County states on its own Building page that it "administers the International Building Code requirements in the issuance of all permits, except within the city limits of St. Anthony." St. Anthony is the ONLY town in Fremont County named in that exception, and therefore the only one that issues its own building permits. - Fremont County has adopted the 2018 IRC, 2018 IBC and 2018 IECC. The City of St. Anthony's own residential building permit application (Rev. 11.2023) names a different list: the International Building Code, the International Existing Building Code, the Idaho Residential Code, IDAPA 07.03.01, the Idaho State Plumbing Code, the 2017 NEC with IDAPA 07.01.01–07.01.11 amendments, the 2012 IMC, 2012 IFGC and 2012 IRC, and the 2015 Fire Code administered by the Idaho State Fire Marshal. - Fremont County Ordinance No. 2005-02, Section 3 sets a ground snow load of 50 PSF for the St. Anthony District — the lowest district figure in the county. The University of Idaho's "Ground Snow Loads for Idaho — 2015" recommends 37 psf for St. Anthony at 4,963 ft, so the county's adopted figure is the more conservative of the two. - Fremont County's Pre-Construction Check List (rev. 17 April 2026) requires engineered stamped plans for ALL free-standing post and beam structures, with no size or snow-load exemption stated. It also requires structures built "within a 70lb/ft² roof snow load" to be designed by an Idaho-licensed structural engineer or architect; the St. Anthony District's 50 PSF appears to fall below that threshold, but the wording does not say "or more" and the county should be asked directly. - The county caps buildings at 30 feet and accessory structures at 25 feet. - Inside St. Anthony city limits: zoning permit approval is required before the building permit is issued; a $150 deposit is required before the application is accepted; water and sewer hookup fees must be paid before building permit approval; submittal documents must be prepared or signed off by a registered design professional; and sidewalk, street and concrete curb and gutter along the street frontage are required before a certificate of occupancy is issued (SAMC 17.09.010(5)). Inspections: (208) 709-3030, 24 hours' notice. - Outside the city limits: a deposit is due on submittal, a $50 site plan review fee applies, two sets of plans with engineering calculations and truss designs are required, permits are valid for two years, the application must be signed by the land owner or accompanied by a signed permission letter, review takes approximately 4 to 6 weeks, and a septic permit from Eastern Idaho Public Health is required upon submittal. - City of St. Anthony: 420 N Bridge Street Suite A, (208) 624-3494.

Deliberately NOT stated here: setback, lot-size and height figures from the City of St. Anthony zoning title. The copy published on the city's own website is footed "Draft" on every page and its section numbering does not match the code the city cites on its current permit form, so its figures are not reproduced on this site. Ask the city office for the operative text. Scope note: this site covers St. Anthony, Parker, Egin and the Fremont County valley floor around them. Other parts of Fremont County sit in different snow-load districts with different design figures and are out of scope here. Business model: free to readers, permanently. No homeowner is ever charged. The site intends to rent its enquiry stream to a single local builder for a flat monthly fee; as of 2026-08-14 no builder pays anything and none has been promised placement. If that changes, /how-this-site-is-paid names the sponsor. ## Core pages - [Who builds custom homes in St. Anthony, Idaho](https://stanthonyhomebuilders.com/): the town's builders from the public record, the city-versus-county permit split, and the county figures every new house satisfies. - [Guides](https://stanthonyhomebuilders.com/guides): every published answer, newest first. - [About](https://stanthonyhomebuilders.com/about): who writes this, and the limits of it. - [Reviews and references](https://stanthonyhomebuilders.com/reviews): why no testimonials are published, and the public records that beat them. - [How this site is paid](https://stanthonyhomebuilders.com/how-this-site-is-paid): the funding model in full, including its honest bias. ## Dated answer pages (newest by publish date) - [St. Anthony is the one town in Fremont County that issues its own building permits](https://stanthonyhomebuilders.com/city-limits-or-county): The county says so in a single sentence on its own Building page, and it names no other town.
