Answers from the rulebook for Hooper
Hooper’s own rules
Building permitRequired
Listed construction work inside Hooper city limits.
The page lists situations that need a permit: converting unfinished space to livable space; additions or modifications to plumbing, water, or gas lines; electrical work other than replacing fixtures, switches, and outlets; HVAC replacement or modification; modifying structural framing; additions to an existing structure; detached accessory buildings over 200 square feet or over one story; and re-roofing.
Structures under 200 square feet require site plan approval, per the page.

New residential homes that are part of a subdivision need a common plan permit from the state, per the page.
Construction may proceed only after the permit is issued, so status is conditional.
detached accessory building size threshold: > 200 square feet (Structures less than 200 square feet require site plan approval instead.)
“building permits are required but not limited to the following situations:”
Building code adoptedPartial
Re-roofing work inside Hooper city limits only. The page cites the IRC for re-roofing; it does not state a general code-adoption ordinance.
Partial: the only code adoption language located is for re-roofing. The city's adopting ordinance for the IRC and other codes was not located on an official page.
The page says re-roof work must comply with the current IRC, including roof covering, underlayment, ice barrier, flashing, and ventilation requirements. A roof recover is not permitted when the existing roof is water-soaked or deteriorated, is slate, clay, cement, or asbestos-cement tile, or has two or more layers of roofing.
“all re-roofing work must comply with the applicable requirements of the current irc, including roof covering, underlayment, ice barrier, flashing, and ventilation requirements.”

Land inside Hooper city's limits, where the city's own Zoning and Subdivision Ordinance governs development.

The same page says the ordinance is available for purchase at the city office. The full ordinance text was not retrievable from an official code host during this research.
