Do you need a building permit in Havre, MT?

Havre requires a building permit before a building or premises is created, erected, changed or converted in use or structure; the enforcing officer must determine that the proposal conforms to city zoning before issuing the permit.¹ Havre also applies its adopted building code to all buildings within city limits.¹⁰ An owner doing work on the owner’s property may qualify for Montana’s construction-contractor licensing exemption, subject to resale conditions, but that exemption does not remove applicable building, trade-permit or inspection requirements.⁹ Ask Public Works to identify the building application and inspection schedule for your project.⁴

Who issues building permits in Havre, and how do you apply?

Havre Public Works reviews and signs building-permit applications, and payment is made at City Hall before issuance.⁴ Building, demolition, roofing, sign and miscellaneous applications are available for download and submission in person at City Hall.⁴ Reach Public Works at (406) 265-4941 or [email protected] to discuss the correct application for your project.⁴ Havre’s zoning application requires a scale plat showing actual lot dimensions, building size and other information needed for enforcement and occupancy certification.¹¹ Building-permit fees are set by City Council resolution, and the Director of Public Works maintains the current fee schedule for public inspection.¹²

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

Havre regulates land uses, building dimensions, lot areas, yards and open space by zoning district; district boundaries appear on zoning map A.²¹³ Identify the parcel’s district before sizing a house or laying out a site plan.² In Havre’s Residential-One Family (Class A) district, each dwelling needs at least 1,500 square feet of floor area excluding the garage, and each dwelling unit needs at least 18,000 square feet of lot area.⁶⁷ Class A requires a front yard of at least 40 feet, side yards of at least 30 feet and a rear yard of at least 60 feet; detached garages and accessory buildings share the main building’s side-yard requirement.¹⁴ These are Class A standards, so ask Public Works for the standards applicable to your parcel’s district.²⁴

How do septic and utility connections work inside Havre?

Havre prohibits private cesspools, septic tanks and privy vaults inside city limits.³ Havre requires each building to have an independent public-water connection and, except as otherwise provided, an independent sanitary-sewer connection; a rear building may connect through the front building where no sewer is available for the rear building.¹⁵ A city lot therefore needs a utility-connection plan consistent with Havre’s code, rather than an assumption that a county septic permit will make an off-grid sanitation plan acceptable.¹⁵³ Hill County Environmental Health administers individual sewage permits, and new septic installations or modifications elsewhere in Hill County require a permit.⁵¹⁶ Ask Havre Public Works about city water and sewer service before committing to a lot.⁴

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

We could not confirm Havre’s rules for long-term RV occupancy, temporary camping or tiny-home occupancy on private land; ask Havre Public Works about the proposed use and parcel before relying on any of those options.⁴ A small standalone dwelling in Havre’s Class A district faces the district’s 1,500-square-foot minimum, excluding the garage.⁶ Havre’s published Class A provision limits new trailer, mobile and manufactured homes to qualifying courts, with a grandfathering condition for existing habitable units.¹⁷ Ask Public Works how that provision applies to a proposed HUD-compliant manufactured home.⁴ Montana separately requires municipalities exercising zoning powers to allow an accessory dwelling unit by right on a lot containing a single-family dwelling, with applicable building, fire and health requirements still in force.¹⁸

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

1. Identify the Havre zoning district and check the proposed use, lot area and building layout against that district’s standards.²
2. Discuss the city water and sanitary-sewer connections with Public Works; private septic tanks are prohibited inside Havre.⁴¹⁵³
3. Prepare the scale plat with lot dimensions and building size, then submit the appropriate building application at City Hall for Public Works review.¹¹⁴
4. Obtain zoning conformity and the building permit, including payment at City Hall before issuance.¹⁴
5. Apply for and obtain the certificate of occupancy before placing the permitted building or premises in use.⁸

For a parcel outside Havre city limits, use the Hill County guide for the county’s answers; Havre’s building-code applicability here is expressly within city limits.¹⁰

Watch-outs

• Havre’s temporary certificate of occupancy lasts no more than 6 months during completion of alterations or partial occupancy and cannot be extended.⁸
• We could not confirm Havre’s floodplain-development or general driveway-access approval requirements; ask Public Works to identify the responsible office before choosing a building site or entrance.⁴
