Licensed Utah General Contractor
Full Home Renovations in Utah
Allegiant Construction is a licensed Utah general contractor for full home renovations across Northern Utah. We remove only what is being replaced, phase the work so you know when each area of the house is affected, and carry every room to completion on a written schedule.
What We Build
A Full Renovation, in Construction Order
Scope covers demolition; structural and layout changes; windows and doors; plumbing, mechanical, and electrical updates; insulation; drywall; and complete interior finish.
Demolition, Structural, and Layout Changes
Interior finishes come out, walls are removed or relocated, and openings are widened. New beams, engineered where the design calls for it, carry the loads the old bearing walls held.
Windows and Doors
Rough openings are framed, and new windows and exterior doors are installed, flashed, and sealed against the weather.
Plumbing, Mechanical, and Electrical Updates
Supply and drain lines, the furnace and ductwork, and the electrical service and circuits are replaced or extended through the whole house. Each rough-in is inspected before insulation goes in.
Insulation
Opened walls, attics, and rim joists are insulated and air sealed. The insulation is inspected before any interior finish goes on.
Drywall
Drywall is hung, taped, and finished room by room. Cement backer board goes behind every tiled shower.
Complete Interior Finish
Across the bathrooms, the kitchen, and every other room, shower tile and hard flooring go in first. Cabinetry, countertops, backsplash tile, interior doors, trim, and paint follow. Plumbing fixtures, light fixtures, and any carpet go in last, ahead of the final inspection.
Opening Up a House
What a Whole-Home Renovation Involves
A whole-home renovation opens the structure and every system at once. Three decisions are made in preconstruction, before demolition starts.
Engineering
Walls That Carry Weight
Removing or moving a bearing wall takes a beam and posts sized for the load and chosen before demolition. Where the span falls outside the code's prescriptive tables, the beam and posts are engineered.
Systems
Systems Replaced While the Walls Are Open
Plumbing, ductwork, and wiring are replaced before the walls close. No finished room has to be reopened later.
Living Arrangements
Whether to Stay or Relocate
Some phases of a renovation are easier to live through elsewhere. During preconstruction, we tell you which phases those are.
2021 IRC as Adopted in Utah
Utah Building Code for a Whole-Home Renovation
A renovation of an existing house follows its own rules in the residential code. Utah's amendments add to them. The plan sets out which work meets the current code and which existing work can stay.
New Work Meets Current Code
Additions, alterations, and repairs meet the requirements for new construction without requiring the rest of the house to comply, unless a section states otherwise, under Section R102.7.1. The same section bars work that leaves the house less compliant than it was.
Unaltered Work
Utah adds a sentence to Section R101.2 stating that the code does not require changes to a building component that is not being altered.
Stairs
A rebuilt stair follows Utah's amendments, with risers of no more than 8 inches and treads at least 9 inches deep, under Section R311.7.5. Its headroom stays at 6 feet 8 inches or more, under Section R311.7.2.
Guards
A new loft, landing, or open stair more than 30 inches above the floor below takes a guard at least 36 inches high, or at least 34 inches along the stair itself, under Section R312.1.
Replacement Windows in Bedrooms
A replacement window in an existing bedroom is exempt from Sections R310.2 and R310.4.4. Those sections set the egress minimums for net clear opening, height, and width; the 44-inch maximum sill height; the 36-inch path from an opening under a deck, porch, or cantilever; and the rules for bars, grilles, covers, and screens over the opening. The exemption applies under Section R310.5 when three conditions hold. The window is the manufacturer's largest standard size that fits the existing frame or rough opening; it is the same operating style as the existing window or a style with an equal or greater opening area; and it is not part of a change of occupancy.
Safety Glazing near Doors
New glass beside a door is safety glazing when its bottom edge is less than 60 inches above the floor and it sits within 24 inches of either side of the closed door in the door's plane, under Section R308.4.2. The same applies to glass on a wall less than 180 degrees from that plane within 24 inches of the hinge side of an in-swinging door. The section exempts decorative glazing; glass behind an intervening wall or other permanent barrier; glass beside a door to a closet or storage area 3 feet deep or less, which follows Section R308.4.3 instead; and glass beside the fixed panel of a patio door.
Safety Glazing in Windows
A new single pane over 9 square feet is safety glazing when it lies within 36 inches of a walking surface and has its bottom edge less than 18 inches and its top edge more than 36 inches above the floor, under Section R308.4.3. That section exempts decorative glazing, and glass where a horizontal rail runs 34 to 38 inches above the walking surface beside it. The rail holds 50 pounds per linear foot without touching the glass and stands at least 1 1/2 inches tall in cross section. The section also exempts an outboard pane of insulating or other multiple glazing whose bottom edge is 25 feet or more above grade, a roof, a walking surface, or another surface within 45 degrees of horizontal outside the glass.
Safety Glazing at Stairs
New glass beside a stairway, a landing between flights, or a ramp is safety glazing when its bottom edge is less than 36 inches above the walking surface, under Section R308.4.6. The rule does not apply where a rail meeting the same load and size rules runs 34 to 38 inches above that surface, or where the glass sits 36 inches or more horizontally from it. At the bottom landing of a stairway, glass less than 36 inches above the landing and within a 60-inch horizontal arc less than 180 degrees from the bottom tread nosing is safety glazing, under Section R308.4.7. The exception is glass protected by a guard that complies with Section R312, with the glass more than 18 inches from that guard.
Window U-Factor
New windows and glazed doors in the thermal envelope carry a U-factor of 0.32 or lower, the prescriptive maximum in Utah's energy chapter, unless the work follows the chapter's REScheck or HERS performance path under Section R1101.3.2.
Townhouse Common Walls
In a townhouse, Utah's amendment to Section R302.2 lets plumbing, mechanical ducts, schedule 40 steel gas pipe, and electric service conductors pass through the common wall at, above, or below grade when an access and maintenance agreement or easement is in place.
Water Pressure
Static water pressure in the house stays at 80 psi or less. Wherever the main runs higher, a pressure-reducing valve goes on the domestic water piping at its connection to the water service pipe, under Section P2903.3.2.
Fixture Supplies
The residential code calls for a shutoff valve on each supply pipe to a fixture or plumbing appliance other than a tub or shower, under Section P2903.9.3. Utah's amendment to that section exempts a fixture or plumbing appliance that has a wall-mount valve. Utah's amendments to Table P2903.2 cap lavatory faucets at 1.5 and showerheads at 2 gallons per minute.
Water Heater Bracing
A new or relocated water heater is anchored or strapped against earthquake motion, with any strapping at points in the upper and lower thirds of the tank, under Utah's Section P2801.8.
Equipment Sizing
New heating and cooling equipment is sized with ACCA Manual S or another sizing method, from loads calculated with ACCA Manual J or another method, under Section M1401.3. Under Utah's Section M1401.3.1, the person who calculates the loads qualifies through ACCA training, a recognized school, manufacturer training, or another recognized certification.
Duct Insulation
Ducts that run outside conditioned space are insulated to at least R-8, and ducts buried beneath a concrete floor need none, under Section R1104.2 of Utah's energy chapter.
Service Panels
Until July 1, 2027, when state law repeals it, Utah's amendment to Section E3601.7 allows the service disconnecting means to be up to six switches or six sets of breakers in one enclosure or a group of separate enclosures. After that date, the model code permits one service disconnect, or two to six grouped disconnects in separate enclosures, separate panelboards, or separate compartments of a metering center.
Arc-Fault and Ground-Fault Protection
Utah's amendments delete the residential code's arc-fault circuit interrupter sections, including the rule for extending existing circuits. GFCI protection still applies to receptacles in bathrooms, garages, outdoor locations, and unfinished basements; to those serving kitchen countertops; and to those in laundry areas, under Section E3902.
Tamper-Resistant Receptacles
New 15- and 20-amp receptacles are listed tamper-resistant, under Section E4002.14. The exceptions are receptacles more than 5 1/2 feet above the floor, those built into a fixture or appliance, and a single or duplex receptacle serving one or two appliances in a space dedicated to them, where the appliances are not easily moved.
Insulation
New or rebuilt exterior walls and ceilings meet Utah's energy chapter, through its prescriptive values of R-21 for above-grade walls and R-38 for ceilings or through its REScheck or HERS performance path.
Insulation Inspection
Insulation is verified by inspection before interior finishes cover it, under Section R1102.4. Utah's Section R109.1.5 gives the building official authority to inspect its installation.
Garage Door and Wall
The door between an attached garage and the house is solid wood or solid or honeycomb-core steel at least 1 3/8 inches thick, or a 20-minute fire-rated door, and never opens into a bedroom, under Section R302.5.1. Utah's version of that section deletes the requirement that the door be self-latching and self-closing or automatic-closing. The garage side of the shared wall carries at least 1/2-inch gypsum board or equivalent, under Table R302.6.
Smoke and Carbon Monoxide Alarms
A renovation that needs a permit brings the home's smoke alarms, and its carbon monoxide alarms where a fuel-fired appliance or an attached garage with an opening into the house is present, up to the locations required for new homes, under Sections R314.2.2 and R315.2.2. Exterior-only work is exempt from both rules; the smoke alarm rule also exempts plumbing or mechanical work, and the carbon monoxide rule exempts plumbing work and mechanical work that is not fuel fired.
Alarm Power and Interconnection
Alarms added to an existing home under those sections may be battery powered, and listed wireless alarms meet the interconnection rule when every alarm sounds together, under Sections R314.6, R314.4, R315.6, and R315.5.

How We Build
Our Remodeling and Construction Process
Every Allegiant Construction project moves through three phases, from the first measurement to the last punch list item. As your general contractor, we manage the permits, inspections, and schedule in each one.
Design and Preconstruction
We measure your space, produce permit-ready plans, and help you finalize every selection. We set the scope, the schedule, and the contractor's fee in writing and secure permits through the Authority Having Jurisdiction before demolition begins.
Construction
Demolition, framing, plumbing, mechanical, and electrical rough-in, and finishes proceed in sequence, with the work area sealed off and your questions answered the same day. Rough-in and framing pass their inspections before insulation and drywall cover them, and any change goes through a written change order before that work proceeds.
Completion and Closeout
We pass final inspection, walk the finished space together, create the punch list, and complete every remaining item. Your one-year warranty on work and materials begins at substantial completion, and warranty calls come directly to Allegiant Construction.
What It Can Become
What a Full Renovation Can Change
Each of the four directions below is drawn into one plan for the whole house before the first area is opened.
Floor Plan
A New Floor Plan
Separate, closed rooms are reworked into connected living areas suited to the household.
Older Homes
A House Brought Current
Windows, plumbing, wiring, and insulation from earlier decades are replaced to the current code.
Investment
A Property for Sale or Rent
A dated rental or resale property is renovated throughout on a schedule built around its listing or lease date.
Long Term
A Home Adapted for Later Years
Wider doorways, a main-level bedroom, and curbless showers are planned into the renovation from the start.
Concept directions for planning, not past projects.
Design Choices
Whole-Home Renovation Options in Utah
A full renovation can reach every system and surface in the house. These decisions set its scope.
Floor Plan
An open kitchen, dining, and living area; a main-level primary suite; a relocated laundry room; or a mudroom at the garage entry.
Exterior Envelope
Roofing, windows and exterior doors, siding, and insulation.
Plumbing and Mechanical
Repiped supply lines, new drains, and a new water heater; a new furnace or heat pump, air conditioning, and ductwork sized to the renovated house.
Electrical
An upgraded electrical service and panel, new circuits for the kitchen and bathrooms, and rewired rooms.
Bathrooms and Kitchens
Each bathroom and kitchen rebuilt with its own ventilation, tile, cabinetry, and fixtures.
Interior Finishes
Hard flooring, interior doors, trim, paint, lighting, and any carpet throughout the house.
How We Price
How Much Does a Whole-Home Renovation Cost in Utah?
Most whole-home renovations are built on open-book, cost-plus terms: actual costs are billed as incurred, and the contractor's fee is a percentage fixed once the contract is signed. Conditions found inside old walls are priced through written change orders.
Age of the House
Older homes can hide conditions behind the walls. Those conditions are priced once the walls are opened.
Structural Changes
Moving bearing walls or opening the floor plan adds beams, inspections, and engineering where the design calls for it.
Windows and Exterior
Adding new roofing, windows, doors, or siding extends the scope to the exterior envelope.
Systems
The cost turns on whether plumbing, ductwork, and wiring are replaced throughout or only extended.
Code Updates
A permitted renovation includes new windows that meet the energy chapter, insulation in opened walls, smoke alarms, and carbon monoxide alarms where they apply.
Bathrooms and Kitchens
Each bathroom and kitchen in the renovation carries its own tile, cabinetry, and fixture selections.
The cost of a whole-home renovation in Utah depends on the size and age of the house, the structural changes, the exterior work, the systems replaced, and your selections. A walkthrough comes first, then a written, non-binding estimate.

What Homeowners Ask
Utah Home Renovation Questions
Do you renovate homes for investors?
Yes. Choose Investment Property when you request a consultation, and we plan the renovation around your schedule for sale or rent.
Can you renovate a home I just bought before I move in?
Yes. Renovating before move-in lets the work run without phasing around the household. The schedule is planned from your closing date.
Do I need an architect for a home renovation?
Not under Utah's licensing law. Under Utah Code 58-3a-304, plans for one- and two-family dwellings are exempt from the architect licensing requirement. A residential designer can prepare the drawings. Any structural element beyond the code's prescriptive limits is designed to accepted engineering practice.
Do you work with architects on renovations?
Yes. We build to the architect's drawings and bring any field condition back to the architect before that part of the work proceeds.
Does removing a wall require an engineer?
Not always. When the beam and posts that replace a bearing wall fall outside the code's prescriptive tables, they are designed to accepted engineering practice under Section R301.1.3. Where special conditions exist, the building official can require a registered design professional to prepare the construction documents for the beam and posts. Those documents then become part of the permit set.
Do I need a permit to renovate a whole home in Utah?
Yes. Structural, plumbing, mechanical, and electrical work each needs a permit from your city, town, county, or district building office. Each is then inspected through final approval.
Do I have to bring my whole house up to code during a renovation?
No. The renovated work meets the current code without requiring the rest of the house to comply. Utah's amendments add that a component not being altered does not have to change. A permitted renovation does update the smoke alarms, and the carbon monoxide alarms where they apply.
Can replacement windows keep the existing openings?
Yes. A replacement window that serves as a bedroom's emergency escape and rescue opening keeps the existing opening when it meets Section R310.5. The window is the manufacturer's largest standard size that fits the existing frame or rough opening, in the same operating style or a style with an equal or greater opening area, with no change of occupancy. New windows also meet Utah's energy chapter, through its prescriptive maximum U-factor of 0.32 or its REScheck or HERS performance path.
What water pressure is allowed in a Utah home?
No more than 80 psi static. Where the main serving the house runs higher, a pressure-reducing valve is installed at the connection between the domestic water piping and the water service pipe.
Does new HVAC equipment need a load calculation in Utah?
Yes. Utah requires heating and cooling equipment to be sized from a load calculation made with ACCA Manual J or another method, by a person who has completed HVAC training the code recognizes.
Does Utah require AFCI breakers in a renovation?
Not under the residential code as Utah adopted it. Utah's amendments delete the arc-fault sections, including the rule for extending or modifying existing branch circuits, and keep ground-fault protection for the 125-volt, 15- and 20-amp receptacles Section E3902 still lists.
Does the door from the garage need to be fire rated?
Not necessarily. It needs to be solid wood or solid or honeycomb-core steel at least 1 3/8 inches thick, or a 20-minute fire-rated door, and it may not open into a bedroom. Utah's amendments remove the residential code's requirement that the door be self-latching and self-closing or automatic-closing.
How long does a whole-home renovation take?
A whole-home renovation runs longer than a single-room remodel, because every system and room is involved. The phased schedule is set in writing during preconstruction.
Can a renovation be done in phases?
Yes. The house can be renovated in stages, such as the kitchen and main level first and the bedrooms after. Each phase is planned during preconstruction and inspected as it is built.
What happens when problems are found behind the walls?
Conditions found once the walls are open, such as damaged framing, failing supply lines, or outdated wiring, are documented and priced in a written change order. You approve it before that work proceeds.
Do I need to move out during a full renovation?
Some households move out for part of the schedule. Whether yours needs to depends on which systems are shut off and when. You will know before demolition starts.
