Do you need a building permit in Carey, Idaho?

Carey requires the owner or authorized agent to obtain a building permit before construction, enlargement, alteration, repair, relocation, demolition or an occupancy change regulated by the city building code.¹ Carey’s published requirement also covers regulated electrical, gas, mechanical and plumbing work.¹ Idaho’s state-administered electrical, plumbing and HVAC permit programs may require separate trade permits, with administration varying by location; ask Carey Planning & Zoning which authority handles each part of your project.⁹³

Who handles building permits and inspections in Carey?

Carey contracts with SAFEbuilt for building plan reviews for building permit issuance and for building inspections.³ All contact with SAFEbuilt starts through Carey’s Planning & Zoning Department, so use the city counter to coordinate the project.³ Carey’s building office lists (208) 720-9981 as its contact number.³ The city’s procedure directs applicants to obtain a building permit application at City Hall or download it from the city website.¹⁰ Ask that office for the current inspection schedule and requirements before booking construction work.

Does Carey have zoning, and what about RVs and tiny homes?

Carey administers municipal zoning for land inside city limits.² Carey Planning & Zoning processes applications and addresses city land-use issues.¹¹ Before buying a parcel, ask that department to identify the zoning district and supply the current permitted uses, lot-size requirements, setbacks and height limits for your proposed home. We could not confirm Carey’s rules for living in an RV, occupying a tiny home, temporary camping or adding an accessory dwelling. Ask Carey Planning & Zoning for a written answer covering the proposed structure, its use and the duration of occupancy.

How do septic permits work inside Carey?

For a Carey property needing onsite wastewater disposal, Idaho’s public health districts administer the state septic rules, and South Central Public Health District serves Blaine County.⁴⁵ Idaho generally requires an installation permit to install, modify, expand or repair an individual or subsurface disposal system, with limited exceptions for specified repairs and approved temporary nondischarging systems.¹² Public or central wastewater facilities being reasonably accessible can be grounds to deny a septic permit.⁶ Carey’s building application must be signed by South Central District Health when the city is not providing services to the building location.¹⁰ Ask the city about sewer service before designing a septic system.

Building a home in Carey: what steps come first?

Start with Carey Planning & Zoning: the city’s building permit procedure tells applicants to determine zoning compliance and any floodplain or engineering restrictions before obtaining an application.¹⁰ Next, obtain the city building permit application and ask for the current plan-submittal checklist.¹⁰ Route building review through Planning & Zoning, which coordinates SAFEbuilt’s work.³ Budget for the applicable building, plan-check, utility, fire and annexation charges listed in the city procedure; the listed fees are due before building permit issuance.¹⁰ If you intend to build personally, Idaho’s contractor-registration exemption requires doing your own work on your own land without intending to sell within 12 months; applicable permits still apply.⁷

What should you check before buying land in Carey?

For land outside Carey city limits, use the Blaine County guide for the county’s building-permit and zoning answers; Carey’s municipal zoning answer applies inside the city.² Before relying on a private well for a Carey home, account for Idaho’s drilling permit requirement and requirement to use an IDWR-licensed well driller.⁸ A driveway connecting to Idaho state highway right-of-way requires an ITD encroachment permit.¹³ Ask Carey Planning & Zoning about floodplain restrictions and local access approval before committing to a house location.¹⁰ We could not confirm Carey’s current building-permit fee amounts or complete dimensional standards; request those directly from the city.

Watch-outs

• We could not confirm Carey’s RV or tiny-home occupancy rules; ask Carey Planning & Zoning before planning to live onsite during construction.¹¹
• A Carey septic proposal may be denied when public or central wastewater facilities are reasonably accessible; settle sewer availability before buying a septic design.⁶
• Idaho requires manufactured-home installations to be inspected and approved by DOPL or the authority having jurisdiction before occupancy; ask Carey Planning & Zoning about the city’s land-use requirements as well.¹⁴
