I spoke with my homebuilder about adding a subpanel for future circuits, including mini splits, an RV hookup, and a Tesla charger. They initially quoted me $1250 for this addition, and we verbally agreed. However, when I received the signed commitment, the price jumped to $1800, which the builder claimed was non-negotiable due to tariffs. After the subpanel was installed, I noticed it doesn't seem to facilitate much expansion. I'm curious if this pricing seems normal and fair. I'd appreciate your thoughts! Here's a link to the installation video: [Link](https://youtube.com/shorts/sKi4DlaxYyM?si=MrNcTGGua2sGCqOX)

They might have just installed a larger service panel inside, which could give you room for more breakers. If a separate subpanel was what you specifically agreed upon, then yeah, you probably got the short end of the stick here. Just curious—was this all verbal with no written contract?
This pricing really depends on what the original installation plan was supposed to be. Without more context about your agreement, it’s hard to say if it’s unreasonable. It could be a clever way for them to solve the problem without knowing all the details you were after.
It sounds like you might've been charged extra to move the main service panel inside, especially since an exterior main disconnect is now required by NEC as of 2022. This could've been a misunderstanding between you and the contractor regarding what you wanted. Definitely not cool if they took advantage of the situation!

Totally agree! Depending on what you and the builder discussed, this might be more about a miscommunication than it is about the actual costs.
