Notaries' Expenses in Residential Premises and Taxes

I am a private notary and am forced to work in a regular apartment due to shelling. Now a lot of money is spent on this – for example, on a generator, internet, restoration of the workplace after damage, etc. Does the tax authority have the right not to recognize these expenses of mine simply because I work in a residential premise, and not in an office? How should I properly justify such expenses to avoid problems during inspections?
