I am thinking of opening up a below ground basement for door entrance, I will get the architect but right now I am just trying to figure out where the entrance should be. Is there any requirement where I can place a door, specifically near vertical/horizontal beams?

not enough info there man and you will need an engineer not an architect. just get a reputable framer.

Hi There!

Earl is wright ,You need structural engineer and You have to measure from property line how much space You have,meaning if You don't have 6' ft from the separate entrance to the property line You will have to erect the entrance from the back of the House.

You can put an entrance almost anywhere, however the lintel will very in size. An Engineer or a well experienced framer or architect will be able to determine the proper sized lintel (the length and width of load bearing section above the a window/door) or reinforcement required for the entrance. When building new foundations extra rebar is placed above and around openings to help support the load. If the butt end of the joists are landing above the door more lintel will be needed then if they are running along. It may be unlikely you can put a door under a beam with lintel hight requirements and standard door hight and a traditional 8' foundation wall.

I would recommend having a engineer give you a drawing rather than an architect. There is requirements of where you can cut an opening for a door in an existing foundation wall, depending how many windows and door openings you have above as well as framing structural weight loads.

It doesn't matter at all where it goes,question You posted is wrong,You can put the door anywhere as far structure is concern,what You need to find out if the building department will give You the permit if You don't meet the fire code,meaning if there is not enuf space for fireman to go beside it to the back ,they will not let You erect the entrance on the side of the House, means You will have to install it at the back.

Hello

There are a few parameters but generally is he door is 32 to 36 inches in width it is not an issue whether you do it with permits as we often do or without permits.

Additional steel support can be added to that small opening area if load distribution requires it

Typically 10 feet length clear area is required in order to be able to properly set up all the steps plus the landing with the proper drainage

Hi Maqsood,

Creating a basement walkout is a great boost to any home. You will need a building permit when creating your new door opening. The gentlemen in the previous posts are right about needing a qualified BCIN designer or engineer to stamp your drawings, as well as ensuring you have adequate property set-backs.

Creating the below-grade door opening means you are now digging a path through the earth. This earth is very heavy and is constantly shifting due to seasonal forces. Your new walkout will need one or more retaining walls to keep this heavy earth from caving in your walkway. Retaining walls are typically cast concrete or solid landscape block. It is common practice to incorporate your new stairs with the retaining wall for maximum strength. Drains can be introduced into these walls, which act as a pressure relief for water that can swell behind it.

When your hole is dug, it will become a large catch basin for rain water that will pool in front of your door. Building codes prevent this by requiring a drain line placed near your door, in a sloped concrete pad, to immediately remove any standing water. The door should have an elevated threshold to prevent accumulated snow and water from entering beneath.

Next you will need to cut into your foundation wall for the full opening and ensure you have a properly sized lintel above. Prepare the opening, install your exterior door with weatherproofing, possibly add a motion sensor light fixture above, and enjoy!

Hi There,

The drain from bottom landing can't be connected to storm or sewage system ,that drain goes to sub pump and gets discharged out that way.
