Permit Requirements for Mendon, Utah
For home remodeling and renovation projects in Mendon, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Cache County.
Authority Having Jurisdiction (AHJ)
The governing body responsible for issuing building permits, reviewing plans, and conducting inspections varies depending on exactly where the property sits in Cache County:
- Within City Limits: The Mendon Building Department typically oversees all Mendon building, trade, and safety permits.
- Unincorporated Areas: Properties located outside of official Mendon boundaries are generally governed by the Cache County Building & Safety Division.
Common Remodeling Permit Triggers
Remodeling is a broad category, and permit requirements depend heavily on the scope of your work. While cosmetic updates—such as painting, installing new flooring, or replacing like-for-like kitchen cabinets—generally do not require approval in Utah, you will almost certainly need a permit for the following:
- Space Conversions: Altering non-living spaces (such as finishing a basement, finishing an attic, or converting a garage) into habitable living areas.
- Structural Changes: Removing, adding, or modifying load-bearing walls, headers, or the roofline.
- Demolition: Extensive interior renovations or "gutting" a space often requires a specific demolition permit prior to or concurrent with the standard building permit.
- Systems Alterations: Rerouting plumbing pipes, adding new electrical circuits, or moving HVAC ductwork.

Utah, Cache County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Cache County Building & Safety Division
The Cache County Building & Safety Division is the Authority Having Jurisdiction (AHJ) for building permits and inspections within the county. All permit applications and related documents must be submitted digitally via email to [email protected]. All contractors and subcontractors working on projects in Utah must hold an active license from the State of Utah. For questions regarding permit applications, you can contact the Building Department at (435) 755-1650, press 1.
Unincorporated Areas of Cache County
For properties located in unincorporated areas of Cache County, all permitting is handled by Cache County Corporation. This includes obtaining a Zoning Clearance from the Planning and Zoning Department, which is required for any structure built within these areas. You can verify if your property is in an unincorporated area by using the Cache County Parcel Viewer.
Demolition Permit Triggers
A demolition permit is required for any structure that is to be demolished or moved. To initiate the demolition permit process, you must fill out a Demolition Permit Application and contact the Cache County Building Department for further instructions. Prior to demolition, an inspection for asbestos by a state-certified asbestos inspector is mandatory, unless the structure is a residential building with four units or less built after January 1, 1992, that has never been or will not become a NESHAP facility. Additionally, a dust control plan from the Utah Division of Air Quality (DAQ) is required if disturbing over 10,890 square feet of property. All utilities must be shut off and disconnected before any demolition work begins.
Permit Requirements for Converting Non-Living Spaces
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas generally requires a building permit. This is because the space will be used for living, and therefore must meet current building and safety codes.
Garages
Converting a garage into a living space typically requires a building permit, along with potential electrical, plumbing, and mechanical permits. Detailed plans outlining structural changes, electrical wiring, plumbing alterations, and mechanical system updates are usually necessary for the building permit application. Zoning requirements, such as setback limitations and parking provisions, must also be met.
Attics
Remodeling an attic to create habitable space, such as a bedroom or office, almost always requires a permit. This includes ensuring minimum ceiling heights (at least 50% of the space with a minimum of 7 feet), minimum room dimensions (e.g., 70 square feet, at least 7 feet in any direction), and adequate egress. A habitable attic typically needs two means of egress: a code-compliant staircase and an egress window meeting specific size and sill height requirements. Structural changes, such as altering load-bearing walls or replacing trusses, will require a permit and potentially structural engineering review. New electrical wiring also necessitates an electrical permit.
Unfinished Basements
Finishing an unfinished basement into habitable space, especially for bedrooms, typically requires a permit in Utah. This is to ensure the space meets current safety, fire, and building codes. Permits are generally needed for adding or modifying walls, electrical circuits, plumbing fixtures, or HVAC systems. Bedrooms trigger additional life-safety requirements, including emergency escape and rescue openings (egress windows) that meet specific size and sill height dimensions. Plumbing permits are mandatory if the design includes a bathroom, wet bar, or laundry hookup, and an HVAC permit is required for adding or extending ductwork.

The following statewide building codes and regulations apply universally to all jurisdictions within Utah:
Utah Remodeler Legislation, Codes, and Guidelines
Utah State Building Codes for Remodelers and Residential Renovations
Utah has adopted the 2021 International Codes (I-Codes) suite, which includes the International Building Code (IBC), International Residential Code (IRC), and the International Existing Building Code (IEBC). These codes are effective as of July 1, 2023, and are implemented through the State Construction and Fire Codes Act (Title 15A of the Utah Code).
1. Specific State Statutes and Codes Adopted
Utah specifically adopts the 2021 International Existing Building Code (IEBC) for alterations, repairs, and changes of occupancy in existing buildings. The IEBC provides alternative approaches to current building codes, aiming to avoid cost-prohibitive retrofits. The state also adopts the 2021 International Building Code (IBC) and the 2021 International Residential Code (IRC), along with other related I-Codes such as the International Plumbing Code, International Mechanical Code, and International Energy Conservation Code.
2. Primary State Board or Agencies
The Utah Division of Professional Licensing (DOPL), under the Utah Department of Commerce, is the primary state agency responsible for licensing contractors, including remodelers. The Uniform Building Code Commission also plays a role in overseeing building codes.
3. Classification of Remodels and Demolition Guidelines
Generally, minor cosmetic updates such as interior painting, new flooring, or small cabinet replacements do not require a permit. However, renovations involving structural changes, electrical rewiring, plumbing upgrades, HVAC modifications, additions, alterations to the building's footprint, or changes to load-bearing walls typically necessitate building permits. Converting attics or basements to habitable living spaces would likely be classified as a structural alteration requiring permits and adherence to the IEBC.
Demolition guidelines vary by locality, but generally, a demolition permit is required for the removal of any building or structure containing concrete, electrical systems, heating and air conditioning systems, reinforced steel, or hazardous materials like asbestos or lead-based paints. Small accessory structures built after 1978 and not in a historic district may be exempt from demolition permits, but utility disconnection and proper disposal are still required. Demolition of structures built before 1978 requires a permit and an asbestos survey. Partial demolition involving the removal of structural elements also requires a building permit, and structural plans may be necessary.
