Just an Idea,  it might be worth checking habitat for humanity Restore.

Please send me more details via private massage.

One day I want to do a historic restoration project in NOLA. 

At the end of 2020 I purchased a restoration franchise called AdvantaClean that services from Chapel Hill to Fayetteville, Sanford to Dunn which amongst other things specializes in Mold, Water Damage, and Duct Cleaning.   

I did not take into consideration the possibility of the city deeming it an unsafe structure and requiring an architect or engineer as I had assumed I would simply be restoring the original interior framework of the property through the typical permit application process.

The ReStore can be hit or miss, but when it's hit, it's great.

Also utilizing rehab stores like the Restore can help as well as looking at alternative construction materials. 

He'll be taxed on all of his regular construction activities.There may be a scenario in there but it would take some massaging. 

The normal wear and tear is not as well defined in the regulations as it probably should be, but the general consensus is the landlord can deduct for costs related to cleaning the unit and restoring it to a move-in ready condition. 

Like restore it to good condition.
