This is according to a youtube video I watched of her playing the song live. 
Listen to the song for the strumming pattern.

Capo on 1st fret
Am F C G

                                                   
You are (Am) the most (F) important (C) person to me (G)
And I've been watching (Am) your light (F) fade (C)
(G) And I can't (Am) seem to say (F)
Anything (C) without (Am) you pointing (F) and yelling (C) at me (G)

But your house (Am) is on fire (F)
(C) I can see it from the end (G)  of the road
Your house (Am) is on fire (F)
(C) Everybody knows 
(G) Everybody knows

Come on get out from under that heavy, heavy coat
Just admit that it's life and you don't think that you can cope
Cuz there are women from our history
That are living underneath your skin
And they're waiting for you to let go and finally give in

But your house is on fire
I can see it from the end of the road
Your house is on fire
Everybody knows baby 
Everybody knows

So ask the help of Jesus ask the help of Allah
No one really cares how many skeletons are in your closet
We will help you open up the windows
Open up your heart flow and let in fresh air
Cuz all I see is smoke rising from your body
As you walk around here you're working the party
Smile on your face dagger in your hand
I'm throwing you a rope my friend
Climb up, climb up here
Onto dry land.

But your house is on fire
I can see it from the end of the road
Your house is on fire
Everybody knows
Everybody knows
