If I remove a Sago palm, including the heart, to ground level, will the plant re-grow? I don’t want to put in more effort than I need to. Just purchased the house and it is to close to the foundation.

First question is how close to your foundation is it? I don't normally see Cycads creating a problems for foundations unlike some trees. A photo or two showing size of your Cycas revoluta will be helpful.

Rather than chopping it down at ground level you can also dig it up and relocate it. Cutting it down to ground level will work on the main caudex but if there are some small subterranean pups they might survive and emerge later. I just posted a pup photo that I intentionally removed from the main caudex of my Encephalartos nubimontanus that finally flushed a leaf after transplanting about 3 years ago.

I see you are in the "North Bay" but wasn't sure which bay you reference.

@Handson777 welcome to Palmtalk! As Tracy said, a sago (Cycas Revoluta) won't damage a house's foundation. The roots are fairly small and not aggressive. Around here they are planted right next to houses, driveways and sidewalks, and the only issue is really frond clearance and (sometimes) a bunch of pups around the base being annoying.

They do transplant easy. If you want it somewhere else I'd wait until fall to move it. I've moved 7 of them to my yard from various places, all of them with a couple of feet of trunk.
