Home additions in Provo and Utah County

A room addition, a second story, or a bump-out that finally gives the family somewhere to be. An addition is a new little building joined to the one you already own. Danny Bird has been building since 2001, and he is the one who prices your job and runs it.

What an addition really is

An addition is a small new building, and then the hard part is joining it to the old one

People picture an addition as one more room. On paper it is. On the ground it is new concrete in the dirt, new framing, and new roof, built to line up with a house that was put together years ago and has settled since.

The room itself is the easy half. The work that makes or breaks the job is the seam: where the new foundation meets the old, where the new roof ties into the existing one so it never leaks, and where the new floor has to land dead level with a floor that is not level anymore. Get the seam right and nobody can tell the house was ever smaller. Get it wrong and you feel the step, you see the crack, and you chase the leak for years.

Blackbird draws the addition and builds it, so the plan and the budget move together. You find out what it costs to go up instead of out while it is still a line on paper, not after the concrete is poured.

The kinds of additions people ask for

Six ways to add space to a Utah County home

Most projects are one of these, or two of them stitched together. Which one fits your house depends as much on your lot and your city as it does on the room you want.

Room addition or bump-out

Pushing a wall out into the yard for a bigger kitchen, a real dining room, an office, or a mudroom. A small bump-out of a few feet is often the cheapest way to fix a room that was always just too tight.

Second story

Building up instead of out when the lot is full or the yard is worth keeping. You are not paying for new ground-level concrete, but you are paying to prove the house below can carry the weight.

Primary suite addition

A bedroom, a real bathroom, and a closet that works, added on so the rest of the house does not have to be torn apart to get it. One of the most requested additions, and one that reliably helps a home sell.

Garage, plus a room above

A new or bigger garage, and often a bonus room, office, or suite over the top of it while the framing is already going up. The stairs and the heat for that upstairs room are the parts people forget to budget.

Accessory dwelling unit

A full second living space with its own kitchen, whether that is a basement apartment or a unit over the garage. Utah has its own rules for these. See basement apartments and ADUs.

Sunroom or enclosing a porch

Turning a covered porch or patio into real, heated, year-round space. It looks simple. Making old outdoor footings and a slab meet indoor code is where the real work hides.

Before and after

Where the money actually goes

Four things decide what an addition costs, and none of them are the paint

An addition is priced by what holds it up and how it joins the house, not by the finishes you can see. Here is where the real number comes from.

New foundation in the ground

Go out into the yard and you need new footings. In Utah those have to reach below the depth the ground freezes, about 30 inches in much of Utah County, so the addition does not heave in winter. That is excavation, concrete, and rebar before a single wall goes up. Going up instead skips most of this, which is why a second story can pencil out cheaper than it looks.

Tying into the roof and walls

This is the part that separates a real builder from a framer. The new roof has to marry the old roof so water always runs off, never into the seam. An exterior wall you are building against becomes an interior wall, which means cutting in, re-flashing, and matching. Done right it disappears. Done cheap it leaks.

Can the house keep up

More square feet means more demand. Your furnace and air conditioner were sized for the old house. Your electrical panel may already be full. A second story adds weight the walls and footings below have to carry, which an engineer checks. We price the panel, the heat, and the structure up front instead of finding it at inspection.

Matching the new to the old

Siding, roofing, windows, and trim have to blend with a house that has weathered for years. Sometimes the old product is gone and the closest match is a judgment call. This is the difference between an addition nobody notices and a box that looks tacked on from the street.

The first real decision

Up or out. It changes the price, the yard, and how long you live in a job site

Almost every addition starts with this fork, and it is worth having an honest answer before you fall in love with a floor plan.

Going out is simpler to live through. The new room is separate from your daily life until the very end, when we open the wall between. The cost is your yard and new foundation in the ground.

Going up keeps your whole lot, which on a tight Utah County parcel is often the only way to add real space at all. The trade is that you are building on top of where you live. It usually means opening the roof, and it leans harder on the structure and the city's height limit. It is not automatically cheaper, but on the right house it is the smart money.

We walk your house and your lot and tell you which one your home actually wants, and roughly what each path costs, before you spend a dollar on drawings.

Approvals

What your city looks at before an addition gets approved

Most Utah County cities run their own building department, so the exact numbers shift from Provo to Orem to Lehi. The four questions are the same everywhere, and they decide whether your addition goes out, goes up, or does not go at all.

Setbacks: how close to the line

Every city sets how close you can build to each property line. A side-yard setback is often the single rule that kills a bump-out, or forces it to the back instead. It is the first thing we check on your lot, before anything gets drawn.

Lot coverage: how much you can cover

Cities limit how much of your lot can be under roof. A big single-story addition can run you into that cap. When it does, going up is often the only way left to add the space you want.

Height, for a second story

Building up runs into a height limit and, sometimes, an unhappy neighbor with a view. This is the rule most likely to surprise people who assumed up was the easy option.

Floor heights and frost depth

New concrete has to reach below frost depth, and the new floor has to land level with the old one. Miss it and the addition ends up with a step where nobody wanted a step, or a cold room in January.

Choosing who builds it

How to compare addition contractors in Utah County, from someone who bids against them

An addition is one of the hardest residential jobs there is, because it is new construction and a remodel at the same time. Plenty of good remodelers and good framers still get additions wrong at the seam. Here is what to actually look at, and it is not the price on the last page.

Ask who has done the roof tie-in before

The join between the new roof and the old is where additions leak. Ask, plainly, how they will flash and tie the two roofs together, and how many times they have done it. A real builder has a clear answer. A vague one is a warning.

Make them price the surprises out loud

A cheap bid is usually cheap because it left things out: the panel upgrade, the frost footings, the engineer for a second story, the match on old siding. The lowest number often becomes the highest once the change orders land. Ask what is not in the price.

One contract, or a stack of subs you manage

On an addition the concrete crew, the framers, the roofer, and the plumber all have to hand off cleanly. Find out who owns that handoff. If the answer is that you coordinate the subs, the risk just moved to you.

Who actually shows up and answers the phone

Ask who prices the job, who runs it, and who you call when something needs a decision at 4 p.m. If those are three different people and none of them is the owner, you will feel it. At Blackbird all three are Danny.

Check the license and that it is in writing

A Utah contractor license and real insurance are the floor, not the ceiling. Just as important: is the whole scope written down, line by line, so you can see what you are buying. A one-page total is not a bid, it is a hope.

Look for additions, not just kitchens

Ask to see additions specifically, not remodels. Building past the walls you have is a different animal, with concrete and structure and roof work a finish remodeler may rarely touch. You want the crew that treats the addition as the main event.

Questions

Home additions in Utah County

How much does a home addition cost in Utah County?
It depends far more on the foundation, the roof tie-in, and whether the house can carry the new load than on the finishes. A simple bump-out and a full second story are not close to the same number, even at the same square footage. Anyone who gives you a price per square foot before walking your house and your lot is guessing. We would rather build you a real budget, broken out line by line, which is free. An average will just be wrong for your home.
Is it cheaper to add on or to build up?
Building up is often cheaper than building out, because you skip most of the new foundation and you do not lose any yard. That is not a rule, though. Going up leans harder on the structure below, usually means opening the roof, and runs into the city's height limit. On a full lot it is frequently the only way to add real space. We look at your house and your lot and tell you which one is the smart money before you pay for drawings.
Do I need a permit and drawings for an addition?
Yes. Any time you change the size of the house, the city wants a permit, and an addition almost always needs stamped drawings, especially a second story that adds weight to the structure below. We draw the plans, file with your city, fix whatever the reviewer asks for, and book the inspections. You should never be the one on the phone with the building department.
How close to my property line can I build?
That is set by your city's setback rules, and it is the first thing that decides whether an addition even fits. Side-yard setbacks are usually the tightest and are what most often pushes a bump-out to the back of the house instead of the side. Cities also cap how much of your lot can be under roof. We check both against your actual lot lines before anything gets designed.
Will the addition match the rest of my house?
That is the whole job. Matching the siding, the roof, the windows, and the trim so the addition reads as part of the original house is what separates good work from a box stuck on the back. Sometimes the old product is discontinued and we find the closest match and blend it. Done right, nobody can tell where the old house ends and the new one begins.
Can I live in the house while you build the addition?
Usually yes, and that is one of the quiet advantages of adding on. When we build out into the yard, the new room stays sealed off from your daily life until the very end, when we open the wall between old and new. A second story is more disruptive because we open the roof, so we plan that stretch with you honestly before you sign, instead of you finding out in week three.
Does an addition add value to my home?
The additions that pay back best are the ones that fix what buyers actually count: a real primary suite, another proper bathroom, or a bedroom in a house that was short one. Space that just makes the house bigger without fixing a shortage pays back less. We are happy to tell you honestly where your money does the most good, even when that is a smaller job than you walked in expecting.
Do I need an architect before I call you?
No. If you already have plans, we price them and build them. If you do not, we can draw the plans and build the job under one contract. That keeps the plan honest, because the builder is in the room while the addition is being drawn, catching what a wall costs to move while moving it is still a line on paper. Bring a sketch, a photo, or just the number you have to work with.
