Avocado tree's distance from the house?
The following thread was started by Twan on November 13, 2010 at 9:15 am PST
Under no circumstances should you plant a tree whose bole or limbs will come closer than 10 ft. to a residential building. If you are in a wildfire-prone area, the district might require a 30ft. tree-free buffer around the house. This is increasingly showing up as a requirement in homeowner insurance policies as well.

Yes, at least 10 feet
Yes, I agree with Steve, at least 10 feet. That is if you are going to keep it smaller, as one can much easier with a Holiday.
I have seen tall large 40 to 60 feet trees with trunk diameters around 2 feet, 10 feet away from homes, with no observable damage or cracks to the foundations. But then not inspecting the foundation fully and crawling under the home, who can before sure. But there were not obviously visible signs of damage.
I have seen avocado trees easily and quite often uplift side walks with 8 feet of the trunk, but then they don't have much weight or depth. A factor too is keeping it water happy, the problems I have seen, are usually in yards where the tree was not well watered and they go looking for water, and large roots come to the surface.

Holiday avocado trees are smallish trees that are not nearly as agressive as most other avocados. My 18 month old tree is a whopping 3 feet high. Of course, it is important not to out-think common sense, but it is much less an issue with this variety.

Thanks for all the input, everyone :) I'll heed your advices and plant the tree as far away from the house at I can.

plant as close as you want
i plant trees close to my house which shades and reduce my heating bill. when doing so i get a 24-30 inch resin based pot, cut the hole out of the bottom of the pot then dig a big hole and sink the pot into that, which controls the spread but allows a tap root. i have holiday avacoados and other smaller less agressive tree planted in a narrow side yard using this technique. and keep the trees trimmed or espaliered and drip irrigated so the root structure does not have to expand, the roots stay where the water is and i dont let the the crown spread much beyond the od of the pot size i select which controls the growth. you cant go by rules of thumb some trees need to be much further than 10 feet from the house like walnut trees which need to be about 20-40 feet depending on the variety. a holiday can probably be safely planted only a few feet from the house even without the potting technique. remember to mound it or elevate it. good luck.

Avocado next to the house?
I would not plant an avocado tree right next to the house, no matter how "dwarfing" the avocado may be. Avocados have seriously invasive roots and will mess not only with your house foundation but also with pipes.
The potting idea Steve has is pretty good if you really want to do it. If the pot is deep enough, you should be able to prevent lateral root growth.

Root spread control
Thanks, Steve, for such detail information. I don't think I have the talent or patient to do it. But it's good to know. Thanks, Axel, for your input too. I think I have found a spot that is about 15 feet from my house and 10 feet from the fence. So it's safe for the neighbor's house as well as mine.
