Licensed & Insured
Utah Contractor License #14292867-5501. Additions are built under a licensed general contracting scope with permits and inspections handled for you.
Veteran-Owned
An addition is a months-long project. Military discipline means a realistic schedule, clear communication, and a site that respects your family's daily life.
One Crew, Whole Scope
Foundation, framing, roof tie-in, siding match, and interior finish — coordinated by one general contractor instead of a parade of separate trades.
Home addition services we provide
Room Additions
Ground-floor additions for bedrooms, family rooms, and expanded living space — from foundation and framing through roofing and finishes.
Bump-Outs & Kitchen Expansions
Small-scale expansions that add usable square footage to kitchens, dining areas, and bathrooms without a full-room addition.
Primary Suite Additions
Bedroom, bath, and closet suites built to the scale and layout your home can support — including accessible layouts when planned from the start.
Multigenerational & In-Law Suites
Private suite additions with sleeping, bathing, and living space for aging parents or adult family members, designed around both independence and togetherness.
Second-Story Addition Feasibility & Framing
Adding up requires evaluating whether existing walls and foundations can carry the load. We assess feasibility honestly, then coordinate the engineering and structure when it makes sense.
Garage-to-Living-Space Conversions
Turning garage square footage into livable space — insulation, flooring, HVAC extension, and the exterior work that keeps the front of the home looking intentional.
Sunrooms & Enclosed Porches
Four-season rooms and enclosed porches designed for Utah's climate, with glazing, insulation, and heating choices made before framing starts.
Mudroom & Laundry Additions
Purpose-built entries, mudroom lockers, and laundry space additions that solve the daily-traffic problems floor plans forget.
Foundations, Framing & Roof Tie-Ins
The technical core of every addition: footings and foundations, structural framing, and a roof and weather envelope that ties into the existing house without leaks.
Permits, Setbacks & Design Coordination
Additions need city permits, setback compliance, and often HOA review. We coordinate drawings, submittals, and inspections so the project moves instead of stalling.
An addition is a small house attached to a big one
The visible part of an addition — the new room — is the easy part. What determines whether it lasts is everything underneath and around it: the foundation, the structural tie-in to the existing frame, the roofline intersection, and how water is managed where old meets new.
As a licensed general contractor, ZZYZX Construction handles that whole system. We plan the structural connection before the first shovel, match or deliberately complement your existing exterior, and sequence the work so your household keeps functioning while the addition takes shape.
We are also honest about feasibility. Not every lot can support every addition — setbacks, easements, and existing structure set real limits. We will tell you what your property can support before you fall in love with a plan it cannot hold.

How much does a home addition cost?
It depends on size, foundation type, site access, and finish level. After measuring the site and discussing your goals, we provide a written, itemized estimate — so you know the cost before anything is built, with no charge for the estimate.
Do I need a permit for a home addition?
Yes — additions require building permits in essentially every city we serve, covering structural, electrical, plumbing, and energy elements. We prepare and manage the permit submittals and inspections as part of the project.
How long does an addition take to build?
Most single-room additions run several weeks to a few months depending on size, foundation work, and inspection sequencing. Weather affects foundation and framing stages, so we build a realistic schedule with weather allowance into the plan.
Can you match my home's existing exterior?
Usually yes — we source siding, brick, and trim to match or closely complement what your home has. For older materials that are no longer made, we show you the closest available options before ordering so there are no surprises on install day.
What is the difference between a bump-out and a full addition?
A bump-out extends an existing room a few feet, often on cantilevered framing or a small foundation, and usually skips a basement. A full addition is a new structure with its own foundation and roof tie-in. The right choice depends on how much space you need and what your lot allows.
Can you build an in-law suite or multigenerational addition?
Yes. Multigenerational suites are one of our specialties — private bedroom and bath space with layouts that balance independence for the occupant with connection to the rest of the home. Accessibility features can be designed in from the start rather than retrofitted.
