THinking of raising an 840 sq ft Cape Cod House to add a walk out basement no interior accesss This also enables me to hook into town sewers GIVES me useful space no new taxes I THINK? ANY ideas or costs

What kind of foundation exists now? Crawl space? How deep? Or a slab? How many steps up from grade to the first floor, if any?

Do you want to literally raise the house? Or do you want to dig the foundation deeper? Or both? You said "walk-out", but would it be basically walk-out all the way around? If you raise the house to create a walk-out basement, would you then have to climb almost a full flight of stairs to enter the house? What will the effect of that be on resale value? (I think I know the answer) Why can't you hook into town sewers as the house is now?

You will really only know the cost when you get a price from a reputable local contractor. It is impossible to see all the little labor-intensive details that will have to be addressed.

It sounds like a good idea, but it really depends on the condition of the home and existing foundation if raising it will be possible and cost effective.

You are in a good part of the states to find a reputable contractor who's familiar with what kind of work goes into lifting and resetting antique homes.

Would adding a mud room type space leading down to your basement and out to the back yard affect your taxes? It might make using your basement more all weather friendly.

Is this an attempt to work around the codes limiting the # of bedrooms on the Cape?
Are you literaly thinking of lifting the house up one story, or will code allow you to just raise the roof to add a story?
I've seen more affordable ideas to get around the 2-bedroom rule on the cape. If you are thinging of arguing that the old first floor is now "basement storage", you might think of raising the roof and calling it a "family room". Then, after the fact, put in pocket doors and murphy beds. Friends in Eastham did that.
Just throwing out a few things for you to think about before you do something drastic like hiring cranes to lift your house.

We raised our ranch and put in a whole new basement with a walkout. This added an additional 2,000sq ft. House was put on steel beams and supported as the basement was dug out. New foundation is a pour cement wall with 2 inches of insulation on bothsides of the cement. Process cost is $80,000. Well worth the money for 2000sq ft. Good Luck

Raising house due to the fact that the sewer is up hill it needs to be raised for gravity. Current basement is 3/4 dirt and 1/4 dug out dirt to 8ft height. House will have 2 walk out sides after backfilled. We are trying to get an idea of the cost of raising it

Probably at leats ten times the cost of a good duplex ejector pump or grinder pump to get your sewage up the hill.
