Detached Garages & Shops Built in Albuquerque, NM
The slab thickness, the plate height and the setback check all get settled before we pour — because those are the three things you can never change afterwards.
What We Build
We don't do garage conversions into finished rooms — that's a different trade with different inspections. We do build shells designed for it.

The Slab Is the Garage
Everything else about a garage can be changed later. You can re-side it, re-roof it, rewire it, hang a new door. You cannot change the slab.
So it goes on our quote as a specification rather than as a word: compacted base depth, slab thickness, concrete strength in psi, whether it's mesh or fibre reinforced, where the control joints fall, a thickened edge under the door opening, and a vapour barrier underneath. Every one of those is a number somebody could check.
And there is one question we ask that nobody else seems to: might a two-post lift ever go in here? A lift bolts into the slab and needs a specified thickness and strength beneath it. Answering 'maybe one day' costs a couple of thousand dollars now. Answering it after the pour means saw-cutting and re-pouring a section, which costs several times that and never looks right.
The same logic covers a floor drain, a trench for an air line, or conduit for a future sub-panel. All cheap in the trench, all expensive through cured concrete.

Five Things That Can't Be Changed Later
A garage is unusual in how front-loaded its irreversible decisions are. All five of these are cheap now and either impossible or painful afterwards.
Slab thickness and strength
Four inches is the normal default. Five to six where a lift, a truck or an RV is in the picture. Adding it later means cutting concrete.
Plate height
Eight feet is standard and ten feet is transformative — a lift, overhead storage, a taller door. It costs surprisingly little at framing and effectively cannot be raised afterwards.
Door opening width and height
Set by the framing and the header. A nine-foot-wide door on a two-car garage is worth the small extra over eight, and a taller opening is what makes an RV garage an RV garage.
Utility rough-ins
Conduit, a sub-panel location, water and sewer stubs if a casita is ever plausible. Trenching in open ground is inexpensive; chasing through a finished slab is not.
Where the building actually sits
Driven by setbacks, easements, lot coverage and where the driveway can reach. Moving a garage after it's staked is a redesign, and after it's poured it's a demolition.
We'll Tell You What Will Actually Fit
Before any drawing, we check your setbacks, easements and lot coverage and tell you the largest garage your lot allows. Sometimes that's bigger than you hoped. Often it isn't.
Your Lot Decides the Size Before Your Budget Does
Almost everyone arrives with a size in mind and a number in mind. The zoning code has opinions about the first one, and it wins.
Side and rear setbacks
How close a structure may sit to each property line, and it varies by zone and sometimes by whether the building is attached. This single number caps depth on most lots we look at.
Maximum lot coverage
The share of the lot that may be covered by structures, house included. On a smaller lot with an existing house this is often the real limit rather than the setbacks.
Height limits for accessory buildings
Usually lower than for the house, and measured in a specific way. Relevant the moment you want a taller plate or an RV door, which is exactly when it bites.
Where the driveway can reach
A garage you can't comfortably swing into is a garage people park in front of. Turning radius and approach angle constrain siting as much as the code does.
Easements and what's buried
Utility easements you cannot build over, and services running where you'd like footings. We locate before we stake, not after.
Permits and inspections
Foundation, framing, electrical and final. Straightforward when started early and the main source of delay when nobody does. We pull and track them.
Two Extra Feet of Wall Changes What the Building Is
If we could get one point across before somebody signs a garage contract, it would be this one: go taller.
An eight-foot plate height is the default because it uses standard lumber and it's what gets quoted. A ten-foot plate costs a modest amount more — longer studs, a bit more siding and drywall, slightly more roof framing. As a share of the whole project it is small.
What it buys is disproportionate. A two-post lift needs roughly eleven to twelve feet of clear height to raise a car meaningfully, and an eight-foot plate rules it out permanently. Overhead storage racks become usable rather than head-height. A taller door fits a van, a truck with a rack, or a boat on a trailer. The room simply feels like a workshop instead of a box.
And unlike almost everything else, this one is genuinely impossible to add afterwards. You would be removing the roof and rebuilding the walls. We raise it at the estimate stage because there is no second chance to.

Five Steps, and the Zoning Check Comes First
Six to ten weeks from signing for a typical detached garage, most of it permit and cure time.
Zoning & site check
We pull setbacks, coverage and easements and tell you the largest garage the lot will take before drawing anything.
Design & permit
Drawings with the slab spec, plate height and door sizes on them, then the permit submitted and tracked to approval.
Excavate & pour
Base compacted, forms set, vapour barrier and reinforcement placed, slab poured and given proper time to cure.
Frame, roof & skin
Walls raised to the agreed plate height, roof framed and dried in, siding and stucco to match the house.
Door, power & final
Door and opener fitted, electrical rough-in and trim, then the final inspection and a walk-through with you.
Mostly About a Question We Asked
Bramwelt asked whether I'd ever want a lift. I said maybe one day and they specified a thicker slab and a higher plate for a couple of thousand more. Two years later the lift went in over a weekend. Every other bidder just quoted a standard four-inch slab and eight-foot walls.
They pulled up the zoning before drawing anything and told me the rear setback capped me at twenty-six feet deep, not the thirty I'd sketched. Disappointing for about ten minutes and much better than finding out at permit review after paying for drawings.
We think we'll turn it into a casita for my mother in a few years. They roughed in the water and sewer stubs, put the electrical panel where it needs to be, and built the foundation to suit. It added maybe four percent and it saved a fortune later.
Talked me out of the insulated door I'd already decided on, because the garage itself wasn't going to be insulated and the door on its own would have done almost nothing. Put the money into the slab instead. Who does that?
What Owners Ask Before Building
What does a detached garage cost in Albuquerque?
A straightforward two-car detached garage — roughly 22x24, four-inch slab, eight-foot plate, one door, basic electrical — generally lands between $38,000 and $60,000 finished and permitted. A 24x36 with a shop side, a ten-foot plate and a thicker slab runs $65,000 to $95,000. Stucco to match an existing house, a taller door and a lift-rated slab all move it, and all of them are itemised.
What size garage do I actually need?
Two cars comfortably wants 24 feet of width rather than 22 — the two extra feet are the difference between parking and squeezing. Depth of 24 feet fits most vehicles; 26 to 30 gives you a workbench without moving the car out. If a shop matters to you, buy depth before you buy width.
Is detached or attached cheaper?
Attached is usually a little cheaper per square foot — it shares a wall and the utility run is short — but it brings a fire-rated separation assembly, a rated self-closing door into the house, and a roof tie-in that has to be flashed properly. Detached needs its own four walls and a longer trench but avoids all of that and can sit wherever the setbacks allow. Often the deciding factor is simply where the lot has room.
How thick should the slab be?
Four inches over a compacted base is fine for cars and normal use. Five to six inches where a two-post lift, a heavy truck or an RV is involved, and the reinforcement and concrete strength matter as much as the depth. We put thickness, psi and reinforcement on the quote so you can compare it against anyone else's — most quotes just say 'concrete slab'.
I might want a car lift one day. Does that change anything?
It changes two things and both are now-or-never. The slab needs the specified thickness and strength where the posts bolt down, and the building needs enough clear height — roughly eleven to twelve feet — to raise a car usefully. Say 'maybe' and we'll price both; it's a couple of thousand dollars at build and a saw-cut-and-repour afterwards.
Do I need a floor drain?
Often not, and where it is wanted the requirements vary — some jurisdictions restrict what a garage drain may connect to. What we'd always suggest instead is a slight slope toward the door, which costs nothing at the pour and means washing the floor is possible. Ask before, because sloping a cured slab isn't a thing.
Could this become a casita later?
Yes, and building it 'casita-ready' is dramatically cheaper than converting later. That means water and sewer stubs in the trench, the electrical panel positioned for a future load, a plate height that suits finished ceilings, insulation-ready framing and a foundation detail that suits conditioned space. Typically a few percent on the build. Do check the current rules on accessory dwellings for your zone, because they change.
How long does the whole thing take?
Six to ten weeks from signing for a typical detached garage. Design and permit is two to four of those, the slab needs time to cure before framing regardless of how keen everyone is, and framing through final is usually three to four weeks. Stucco adds time and is weather-dependent.
Tell Us If a Lift Is Even a Maybe
That answer and 'might it ever be living space' decide the slab, the height and the trench — the three things that can't be changed later. Maybe is a perfectly good answer.
