Do I have to replace old electrical?

[Robert Obniski]

I look at a property today that was perfect. 3 beds 2 baths not everything in my criteria until I got to the fuse box. It has old electrical throughout the whole house. It was kind of a deal breaker for me being as I would not be carrying any walls down anyways so the electrical wouldn't be touched. My question is if I purchase and renovate the house, do I have to put in all new electrical throughout the house? To bring it up to code.

It's always a good idea to get a service change done on an old fuse box because you'll always need to add a new circuit for something. I'm an electrician in Michigan and that's the only market I know but knob and tube is not the end of the world. In Ann Arbor we see knob and tube all the time. If it's exposed you should replace it, but if everything's working fine then it's been working fine for a century. Just leave it alone. If the house is a ranch replacing all the wiring isn't a huge deal. (A 2 story is however. Plaster and lead paint can be a nightmare.) If you do major renovations then yes the wiring will have to be replaced, but the more walls you open the easier it will be.
