Permits and Inspections

Building Permits in Roy

Roy's Building Division takes every permit application online through City Inspect. The portal also carries plan review responses, revisions, and inspection scheduling.

Roy

Roy Building Division

By legislative action, certain items must be approved by other groups or entities, such as the irrigation company, SWPPP management, the Development Review Committee for nonresidential site plans, water share appropriations, and power departments, before the division can accept an application. The initial review of submitted plans is completed within 14 business days after they are accepted for review. Inspections follow the approved plans and are requested in AM and PM blocks, with a pour time noted for concrete work so the inspector can be there first. Some inspection types cannot be scheduled until the previous required ones have cleared or passed. Before Roy approves a building permit for a home or other noncommercial property, the applicant shows proof of a purchased secondary water supply, or a certificate from the Roy Water Conservancy Subdistrict that none is available. We secure that document before the application goes in.

Building Permits and Inspections

Roy's Building Permit Information for Single-Family and Two-Family Dwellings, revised May 2024, lists these minimum items for the plans, in its own order.

A permit application with contact numbers, contractor license numbers, and the use of the building
A site plan or plot plan of 8 1/2 by 11 inches or larger
A plan of the footings and foundation
A floor plan for each floor
Front, side, and rear elevations
Wall cross sections and details
Plumbing, electrical, and mechanical layouts
The species and grade of lumber, with joist and beam sizes
The insulation R-value for every exterior wall and ceiling and for floor areas over unconditioned space and outside air
Energy compliance documentation by REScheck or another approved method, with Manual J and D calculations for the HVAC system

The city's Residential Additions and Remodels handout uses the same first eight items. For a remodel, it adds a plan of every area to be remodeled with the existing walls to be removed and the new walls to be built. It also asks for the insulation R-value of the ceiling, exterior walls, and floor assembly over unconditioned air space. The Residential Basement Finish handout asks that every room and area be classified as finished or not finished and that existing and new walls be identified. It also asks that the furnace, the water heater, and any electrical panel in the basement be shown, and that the mechanical room be isolated from the conditioned space. The handout also states that engineering is required for altering or removing any structural member, bearing wall, or portion of one.

Accessory Dwelling Units

ADU Rules in Roy

Ordinance 26-9, adopted September 15, 2026, rewrote Roy's ADU rules. Table 17-1 lists a detached ADU as permitted in the RE-20 through R-5 zones, but not the RMH-1 zone, under these conditions, in its own order.

A lot or parcel of 11,000 square feet or larger that already contains a primary dwelling
Additional parking under Table 19-1 in Section 10-19-8, with one space for a unit of 649 square feet or less, or two side-by-side spaces for one of 650 square feet or larger, none of them within the required front setback
Occupancy as the primary residence of the owner of record
No more than one detached ADU per parcel
Rentals of 90 consecutive days or longer
A Rental Dwelling License
The additional requirements of Sections 10-10-28(9) and 10-10-29, set out below
A notice recorded with the county

Section 10-10-28(9) allows an accessory building to be used as a detached ADU only under these standards, in its own order.

No larger than the primary dwelling unit on the same lot or parcel
In the rear yard, 10 feet or more behind the primary dwelling unit and no less than 3 feet from the side and rear property lines, outside any public utility easement or other recorded easement, and never in the front or side yards
A design consistent with the primary dwelling unit
A legally constructed accessory structure allowed to be converted into a detached ADU, subject to the title's detached ADU sections
Replacement elsewhere on site of the primary dwelling's required parking space when a legally constructed garage that held it is converted into a detached ADU
A detached ADU that the city can prohibit when the unit will not have adequate access to required utility services, including sanitary sewer, culinary water, electrical, or storm water, or when the required utility lacks sufficient capacity for it

Section 10-10-28 also allows no separate utility connections or meters for accessory buildings. Section 10-10-29 holds every detached accessory building to one story and a height of no more than 18 feet to the top of the wall plate or 25 feet to the pitch of the roof. Table 17-1 lists an internal ADU as permitted in the same zones, within the footprint of a primary dwelling, including a garage that is habitable space connected to it by a common wall, under these conditions.

An additional parking space under Table 19-1, outside the required front setback
Occupancy as the owner of record's primary residence
Rentals of the unit for 30 consecutive days or longer
A Rental Dwelling License for the unit
A notice recorded with the county for the unit

Utah's ADU statutes apply in Roy as well, as our ADU page explains.

What Homeowners Ask

Roy Remodeling and Permit Questions

When does Roy require a geotechnical report?

Section 10-10-37 of the zoning code requires one with an application for a permitted use, conditional use, site plan, building permit, or any other approval, permit, or license, for any land area or parcel with the potential for soils, earthquake, flood, or other discernible hazards. A registered or licensed geologist, soils engineer, or civil engineer prepares the report.

How long does Roy allow to finish a building's exterior?

One year. Under Section 10-10-18 of the zoning code, all exterior features of a building are completed, and the property is cleared of materials, debris, and equipment, within one year after construction authorized by an approval, permit, or license begins. We plan your project's exterior work to finish inside that year.

What hours can construction run in Roy?

Section 5-2-7 of the municipal code makes it unlawful, between 10 PM and 6 AM, to operate tools or equipment used in construction, drilling, repair, alteration, or demolition work on buildings, structures, or streets when the noise creates a disturbance within a residential area. We schedule every trade on your project outside those hours.
