Tax deduction for Pest Control Room rental

[Franco428]

I am renting a room to someone and I recently found out that I have termites in my condo unit.  If I have it tented am I able to deduct the cost for my unit, or am I only able to deduct a portion of the cost?  Also if I'm doing improvements on a comment use bathroom how much am I able to deduct from my taxes since both of us are using it?

YOu can deduct that percentage of your tenting costs that is equal to the percentage of floor space you have rented out that is exclusive to the tenant. Termite treatment would be a maintenance expenses. Whereas any work done to repair damage caused by termites would be a repair expense. Repairs done in that space exclusive to the tenant would be 100% deductible. Repairs done elsewhere on/in the property would not be deductible at all.
