Are attached garage that much more $$$????

[Monte406SS]

My buddy has not received 2 quotes. 18' wide x 28' deep (do to zoning restrictions) is coming in complete (insulated, sheetrocked, painted, 1 circuit which I told him was a joke, basic 16' wide door uninsulated). First was $85/sf the second one just came in at $120/sf.

Is an attached really that much more? He has very easy access, garage will be extended off the right side where a asphalt driveway currently exists. I know certain items can make the number go up quickly, but this is pretty bare bones as I would expect a garage. Standard height ceiling too, nothing fancy for a lift.

Maybe I am just that disconnected with costs over the past several years.

A detached stands alone, while the attached is connected to the house. Sounds like some pretty common information till you take everything into account.

From the foundation to the shingles on the roof, everything must correspond and be attached to the home

the footer/foundation it must be of equal depth to prevent heaving and causing issues down the road

the siding must match the existing home or a paint match

any windows or doors must match or be closed up,

the garage wall abutting the house will need to be drywall,

electrical will be going through the wall not just through the foundation buried in conduit, does the service line need moved

any water lines or drain lines might need to be moved or found,

roof lines need to match up, possibly reshingling part of house roof and soffits cut back,


Then there is the complete unknown of Murphy's Law when digging, attaching, building next to the home.

At least in PA....its not that things have to match, etc....it's the building requirements and the need for signed plans.

My original plan was to build an attached...and the required architect's plans were over $3000 alone.

If a garage is attached to the house you must follow all the building codes for a residential building. Things like tempered glass within a given space from a door or staircase, staircases must have plans for load carrying, railings, firewalls..the list goes on and on.

Detached, under a given size (if memory serves it was 1200 sq. ft.) there are really no requirements or inspections. For electric, you'd need a permit and inspection...and in my area, we needed an inspection to ensure that we were within the height and setback requirements. But...no detailed, signed plans or following the building code.

Thanks guys, still in sticker shock I guess. Looks like he may just end up not having a garage.....as much as it pains me to say that.

On a new home build I was quoted $40/sq ft to expand the attached garage. That included drywall, concrete, matching brick siding/trim/shingles/etc, but didn't include insulation, electrical, 12' ceiling or garage door, those were all priced separately.

Go to lumberyard and see if they have an arch draftsman that works with them, simple garage addition should not cost more than $1K to design. Have GC's bid on plans and itemize site prep, concrete, framing, etc. Finish interior and elec later as funds allow.

What's the house worth? A garage of that size should increase value, maybe more than its cost.

Yeah...I have a quote more in line with the post above me and about half what your friend is being quoted for my proposed attached garage. Mine includes everything but electric, which wouldn't be much more. I'm in MD, so it's not NJ but it's close. $85-$120/sf seems really excessive. Maybe he should get a few more quotes.

I wish my attached garage build was $120/sf...

 

[Monte406SS]

Thanks guys. He has a small house, so the garage would be a nice selling point if he ever goes down that road. $40/sf he could live with even if it needed some things later on to complete it.

Seems high. When you can build a nice house @ $120/ft^2.

The big differance is in the foundation and fire wall need.
Attached needs to be home style.
Common wall neeeds fire proof.

Fire proof in my county equals adding some 5/8" fire rated drywall to the common wall. Not much of an added expense.
