View Full Version : Attached or Builtin Garages?

05-15-2002, 04:59 PM
Ok I'm confused...

Straight from the Marshall and Swift guide...

ATTACHED GARAGES share a common wall with the residence. The attached garage costs include interior finish for only that wall which is common. (Shows picture of a house with garage which shares its left side wall with the home... garage stretches all the way to rear of the house)

BUILT-IN GARAGES have living area both adjacent to and above. Costs include finish for all common surfaces. (Shows picture of two story house where garage shares left wall with first story, and garage ceiling is the floor for second story. Garage again goes all the way to the back of the house..)

My question is: What is it classified as when the garage shares both its side wall and REAR wall on a single story home?

Unless it's built-in.

Ok, I'll go further.

When you measure the attached garage, you are measuring inside of the attached wall. This leaves the attached wall thickness in with the GLA. I only consider it built-in when there is living space above the garage.

I basically rely on whether the garage is in the basement or attached on the side of the dwelling. Even garages attached on the side with living area above them are considered to be attached in this part of the country. (i.e. finished bonus room or owner's bedroom suite). If the area would be considered basement if it had no garage, I consider it a built-in.
No one has ever questioned me on this.

1 story home- attached. Two story home with bedroom, etc above, its a built-in.

Of course, it's attached.

If there's any attachment to the garage other than one common wall, it's built-in, kind of, generally.

How bout I cut the excess verbage? and add a little bold itallic clarifier of my own:

ATTACHED GARAGES share a common wall(s) with the residence.

BUILT-IN GARAGES have living area both adjacent to and above.

At least in MY mind the defining issue for built in is living area above. Some locations may differ!

I am also prone to call that basement level garage Liz references: even if no living area is above it "built-in" IF one has to desecend a cut-in slope driveway to get to that garage. (eg the 'third' basement garage found in some homes accessed from the rear of the house).

then there is the "tuck under" garage

most reviews I do they all are attached even when GLA above garage.
I considered built when when there is living area ABOVE most of garage.

what if its attached(common wall) but you must walk out the garage and around to the front or rear door to gain entrance to the that really considered attached? functionally?

I have a "built in" garage in my home. The entry to the garage is on the lower level. Directly above it is living area. The home is basically rectangular with and opening on level 1 for the garage. The garage shares front and back walls with living area.

An attach garage shares an exterior wall or two with the living quarters and is outside of the living area of the house and outside of the foundation of the living quarters. It may share two exterior walls (ex. Side and rear of the garage) and still be considered attached.

A built garage is located within the foundation of the living quarters, (hence the name "built-in"...clever) and is generally located in the basement area.

Detached is not connected to the living quarters by any common wall and is accessed by walking outside or through a connecting breezeway or covered porch. (Thought I'd throw that in for someone to disagree with)

Although a half dozen to everyone else's six, I tend to look at it just a little different.

When I first started I asked why would M&S make a distinction? Obvious answer is there is some measurable difference in cost. My guess is that it is mostly associated with the roof. If you use the $GLA for an area over the garage you have already accounted for the roof. The $BI takes this into account.

However, if you convert the BI to GLA you would have the same roof but would not use a $BIGLA. Therefore my reasoning may be flawed or incomplete, but it at least helps me pick between the $BI or $A.

Bemis introduced my thoughts a few posts above here .... what if the wall is common but there is no entry to the home through that wall ? I've been in numerous 50's and 60's-vintage places where one must leave the garage, go out into the elements, and proceed to the front door for entry to home. Some garages may have a single back door, to patio, and then one walks to a rear door entry. Aesthetically, one might consider that as a detached garage. Then too, one can find the true detached parking structure with a side door leading to a covered breezeway where rooves of both structures are connected and someone is protected from the sun, rain, snow and hail. The prime function is ... how many cars can one protect within that garage, and is there extra "over-size" area for keeping their stuff ? Is there attic or upper rafter storage space ? Attached, or detached is less significant.

:lol: :lol:
1.Call it whatever checkbox seeems best to fit for whatever you are doing

2. Disclose why you called it X instead of Y,

3. Adjust according to whether the market cares.

[size=16]It's a STUPID FORM :wink:

I use the KISS method:

If it's under the living area, it's built-in.
If it's attached to the side of the living area, it's attached.
If none of the above it's detached.

The so-called "experts" can confuse a free lunch.
