Itemized Remodel Receipt - 27.5yr vs. De Minimis

[mgc6288]

If I paid for a $20k remodel and the invoice is detailed then can I line item some appliances and depreciate them over 5 years?

Can I De Minimis specific line items if they are under $2500? For example, a closet cost $1800 to add while another line item deals with all the electrical work for $1500?

This is what I'm envisioning from the $20k remodel invoice:

$500 Diswasher: Depreciate over 5 years

$1500 electrical work: De Minimis expense

$1800 closet build: De Minimis expense

$16200 remaining invoice: Depreciate over 27.5 years

Is this allowed? Thanks.
