Hi guys,

I am thinking of putting a pit in the new garage so I anc work under
the cars. How does one go about it? We have a height restriction so I
can't put in a vehicle lift which I would prefer.

My guess is to dig the hole, pour a slab at the base of the hole, then
build a wall of cinder blocks up to the floor level. Is that how it is
done?

Thanks

I would think that the pit would be built first.. think of it as a small
basement. BTW, I would place a drain in the pit as well.

I would bet a lot that you are going to have to get an engineer involved,
even if you could do the work yourself. I wouldn't be suprised if you run
into some other restrictions as well. If I was you, I'd call an engineer
or the appropriate professionals and see what they have to say about the
idea. I've heard of this before, but never known anyone that has gone
through with it.

Would suggest that you check with your township/city/borough/etc.

At least in some parts of NJ, there are very definitive laws about putting in a
pit in a garage or other places.

Better safe than sorry....

No one does.

It's a bad idea, that produces a product that isn't safe to use.

I wanted to have this done to my house being built, but never got a round tuit.
If it's done after the fact, you'd have to make sure to shore up the sides
whilst digging so the dirt walls dont collapse and the garage floor starts
cracking around the pit. I saw one in an old garage once with a dirt floor.
looks like they just dug it out and made it with solid blocks. You won't need a
drain or pump if it's inside. Just make sure its narrow enough for any
potential car to straddle the pit!

If you really want to do this I think you should hire a local engineer
so that person can talk you out of it. I have designed several of these
pits. From a structural point of view they are fairly simple, but then
you run into the safety issues. These pits need both a drain and an
explosion proof exhaust fan. Carbon monoxide is heavier than air. If a
vehicle is running the pit will fill with CO which will displace the
oxygen. You now have a potentially lethal place to work.

In addition, any water collected is now oily sewer and must be treated
to oil water separation before discharging into the sanitary sewer
system.

Ever wonder why the service bays in your local car repair place got away
from pits? The above are two good reasons.

Another reason that repair facilities got away from pits is that they are
illegal. Don't know about personal use, but I worked in a repair shop for 6
years and the pit was boarded over, later filled in. Both CO and gasoline
vapor and most likely other harmful gases collect in them, cave-ins are a
concern too. I have worked on cars for over 40 years and never used nor
needed a pit. I'm currently purchasing an above ground 2-post lift. I have
been using a floor jack/jackstands/creeper, but it's getting harder to get
up off the creeper-someday I'm gonna get stuck.

Another BIG problem is that fuel vapors are heavier than air an will collect
in the pit. Can you spell EXPLOSION?

Every Oil changing place I know of has a pit, they certainly dont use a
hoist.

They must comply with stringent regulations that did not exist some years

not.

They are banned in many areas, NJ is one. I have one and it is a fire

a big headace at sale time.

I have a few classic cars that I love to work on. I'm planning on
building a second detached garage in the future which will definitely
have a lift. And just for convenience it may also get a pit,
especially for the Vette which is a pita to raise with jacks not to
mention possible body damage from flex.

The illegal claim is BS. Just about every oil change place in my area
uses a pit. When you drive in, the center of the pit is covered with
steel grates. Once stopped they just pop the small sections of grates
out for whatever area they want to work on.

Around here, the pit isn't covered- it has steel L-rails on top to reduce
the chances of tires slipping into hole, and the guy waves you in, like
driving into an auto car wash, or onto a lift in the old days before
insurance compaies forbade customers doing that. The double-length pits have
a small bridge in the middle, so they can open the hood on the #2 car. I can
hear the exhaust fan running while trapped in the car, and they do follow
2-man rule.

Not sure what the actual law says- it probably varies by area, and insurance
company rules are probably tighter than law. But a below-ground pit does
present a hazard, esp. if there is natuaral gas and gasoline used in the
structure. Risk is compounded if there are various niches in the pit, and
(drippy) vehicles may be left parked over the pit. The technical term is
'confined space', and OSHA, et al, have ALL SORTS of regs that apply in
commercial situations. Fire departments also get special training in doing
rescues from them.

Yes, I've seen them in older garages, usually covered by planks dropped in
steel edge rails. (Usually very shallow, not standup pits.) Safety hazards
aside, if they were used for draining oil, the spills probably resulted in a
lot of ground water pollution. If local code allows them (or you wanted to
put one in on the QT), I'd strongly suggest building in an exhaust fan
setup. Probably better, if you can build a walkout-basement garage and/or
live in a nice weather area, would be a walk-in pit, or an outdoor raised
area or hillside cut, such that natural airflow would minimize any trapped
gasses. I suspect one of those light-duty drive-on car lifts like they sell
to rich hot-rodders would be about as cheap a solutiion, if there is enough
headroom in garage. Car is held by tires, so no risk to suspension and
flexible body. (Had a VW like that once- jack it up and you couldn't open
the doors.)

For what ?
We have the same thing here in SW FL.
I've been taking my vehicles there for 15 years, best place around for basic
maintenance.
They built an entire basement, then built a berm all around it.
Landscaped, maintained nicely, and an attractive building with a blue barrel
tile roof.
They have 4 bays and the entire floor under them is wide open. There are
guys down there all day long yanking filters and draining crankcases.
So, what are the condolences for ?

Comparing a "Pit" to the below surface work area of a drive-through oil
change service station is the same as comparing a duck to an eagle. (Exhaust
system and lighting both of which are explosion proof, tool and material
storage areas, oil water separator, etc. all of which are OSHA approved) The
OP wanted a pit. Pits are not legal and are dangerous but if you want one go
ahead and build one. Its just that simple.

This one really brought out the arm-chair experts. As noted all of the
fast oil change places around here, and there are 7 of them have pits.

Now you nay-saying "experts" seem to be forming opinions based on
insufficient evidence. I have gone over my original post and I'll be
damned if I can find where I said it wouldn't have a drain, wouldn't
have explosion-roof lighting and wouldn't have a fan, and wouldn't
have...Ohhh shit why bother.

Thanks to those sensible replies.

Now to the jerk who asked about "can we spell explosion" let me ask in
return "have you any idea of the ratio of air to fuel in an open pit
that would cause and explosion of sufficient magnitude to be dangerous
beyond an unpleasant whoomp?" Having done quite a bit of research into
this very subject many years back when I worked as a design engineer
for a petroleum road tanker manufacturer, I can assure you that you
cannot spell shit.

Actually most of them are simply basements the full size if the building.
Well ventilated and having unobstructed exits in case of fire. This is not a
"pit", although some may have a pit it's unlikely building codes would allow
it.

The biggest consideration for an actual pit would be easy exit. Most fires
in these situations result from a trouble light breaking and igniting gas.
If you make a true pit be sure it has a good stairway out one end.

I don't believe the pits are illegal (at least in my state), but they do
require a lot of attention to detail in order to comply with OSHA safety
rules. The pits are classified as "confined work spaces" and must be
vented and drained accordingly.

So, it is possible to build a service pit. Its just a PITA to comply
with all the rules.

Excuse me, but what does OSHA have to do with a residential
situation? Granted there is a need to be concerned with personal
safety (and your home insurer may have some concerns), but AFAIK a
home owner is not subject to OSHA rules. Its more a function of
good sense, what your insurer will cover, and city/county/state
regulations (if any apply to a residence).

What about a set of large ramps? Two to three feet of clearance
underneath is plenty of room for most operations. It's got to be cheaper
than either a pit or lift and easier than jacks or cheap ramps.

BTW I've only seen pits at oil change stores here in IN.

I cite OSHA rules simply to make a point that service pit design is
nothing to just "fool around" with. If someone wants to make a pit in
their own garage and they want to have no ventilation and no drainage
its no skin off my nose. However, they are taking a big risk and as you
correctly point out, the resale value of the house may suffer.

People do stupid stuff in their own homes all the time. Just because
OSHA has some rule about hazardous work place conditions that are
sometimes goofy and sometimes just plain wrong, doesn't make all of
their rules suspect.

As a design consultant I would be exposing myself to enormous liability
if I didn't design a pit such as this to at least a minimum OSHA
Standard. If the homeowner wants to build something himself he's pretty
much free to do whatever he wants. However, there can be consequences:
both financially and safety related.

I had the same idea for my garage, but then I found that in most
localities these are not legal. I heard that this was the case for two
reasons, one safety and one environmental. The safety issue is that
natural gas, and I think gasoline and some other flammable vapors, are
heavier than air and would settle to the bottom of such a pit. This
makes it a hazardous place for a human to work and a potential bomb
waiting for ignition as well. The environmental issue is that this is a
place for oil and other stuff to collect and then ooze into the ground
once the concrete develops the inevitable cracks.

Might want to check with your building inspector before investing too
much in this idea.

Around here (northern PA, upstate NY) all of the garages and oil change
places use above ground lifts. I suspect as with many other issues, the
laws vary a lot from state to state.

More likely the issue here is building code related rather than OSHA.
Since Bob is an engineer, he likely does more commercial work than
residential so that is what he'd have to deal with most often.

What's the *big risk* ?

The resale value may be enhanced !

Interesting that you suppose a pit would be *stupid stuff* Bob.
I have a friend that lives next door to where the *Bush's* vacation, in Boca
Grande, Florida, that has a pit and a lift in his $1.4 mil home (I designed
it !) that he uses to wrench on his vintage 63' split window vette and a
pair of 41' knuckleheads.
He has turned down many offers of $2mil+ for his krib.
Resale ?

Not unless you use propane in your garage, which is a bad idea anyway. I
think a pit in the garage is a great idea, in fact, i'd do it in a minute,
if I had the time and patience.

Good luck on the construction aspects: But keep in mind most solvent
vapors (gasoline) are heavier than air and settle, perhaps into the
pit???

Just a safety thought

Except that OSHA rules do not apply to non-commercial private residences.I

The same would hold true for any garage,even without a pit. That's why it's
not a good idea to have a gas-fired water heater in your garage.

We just finished building our house with a three stall garage. I put our
second set of basement steps in the garage. A friend was over the other
day helping paint and noticed my basement steps were in line with the third
garage door. He said " Look at that, you have your own oil changing pit."
Took some measurements, and the opening is just right. However, I will
never use them for several reasons but they would work for small jobs but
you can't get to the middle of the car. The biggest reason not to is we
need to put a railing around the opening so our kids will not fall in.
Insurance also requires it. But a nice removable railing is aways a
possiblity.

Just another idea.

Carbon Monoxide gas is not significantly heavier than air but gasoline
vapors are. Flammable liquid vapors will tend to accumulate in the pit
until the concentration is in the explosive range. If ignition does
occur you will be lucky to escape without severe burns. every thing
electrical that is used in the pit or adjacent to it has to be very
carefully built. Suitable electrical equipment is expensive to buy and
to have installed.
Unlike others her I will not tell you what to do in your own home. I
will suggest to you that you should undertake this particular project
with much care.
I am a volunteer firefighter rescuer and I have attended a number of
trench collapse incidents. Most of these incidents end tragically. If
you build the pit walls yourself then have the equipment operator dig
the excavation back to at least a forty five degree angle from the base
were you will poor the pit footer up to ground level. After the footer
and pad is poured, and the walls are built the extra portion of the
excavation that ended up outside the pit walls is back filled. Have the
pit built to withstand the pressure of the soil even after torrential
rains. You might want underground drainage installed to keep ground
water out of your pit and to prevent a build up of pressure around its
walls. You may want a floor drain in the pit but you will want an oil
separator in the drain line. In most areas floor drains cannot empty
into the sanitary sewer or into the street storm drains.
If the pit is what you want then build it but do it right.

I had a "pit" in my first garage...and can not understand what trouble it would
be to install one in a new building.. Codes etc maybe?... also make sure you
have a functional drain in the bottom of the pit..And
a metal grate to place over the hole when your are not using it...

But I do not understand the height restrictions...? I have two garages
both have lifts...and both are no taller then a standard garage... you do need
at least a 10 foot ceiling 12 is better..BUT this can be done pretty easy... If
the door is your problem think about a roll up door like those
found on loading docks.. this solves the problem of the door opening into the
garage..

I restore old cars as a hobby and could not survive without the lifts but
for Harry backyard mechanic a pit would work...

I've been researching the pros and cons about a pit. My decision is to build one in my new 3000sf home shop.
I've decided against the post lifts because they take up floor space when not in use, and can't handle some of my heavier toys; i.e. Backhoe, motorhome, antique tractors..
After reviewing other people's wise comments it will contain the following:
-constructed with concrete blocks reinforced with rebar, and concrete filled
-poured concrete floor
-Long enough to handle the wheel base of the dump truck
-Narrow enough to handle the Austin Healey
-Angle iron along edges to accommodate planks for covering when not in use
-explosion proof exhaust fan.
-sump with pump and oil-water seperator.
-120v GFI elect outlets.
-compressed air connections.
-LED lights
-painted gloss white for better visibility (seems like there's never enough light when under a vehicle)
-fire extinguisher
