Portland rehab and permits?

[Justin Leithem]

Hello, I am about to close on my first rehab project in the Se Portland area. I'm curious what I can expect to need permits for and what that process usually looks like? How long does it take to get them, how much etc. I'm specifically curious about adding Windows, removing interior non-load bearing walls, widening doorways, adding doors and moving toilets. I'm planning on going to the city to get it from the horses mouth but I was hoping for some input/advice from experienced investors prior to opening up that can of worms. The home is a 1926 bungalow that's been remodeled through out the years, new electrical and plumbing, etc. Thank you for any input!
