Installing Window Heating/AC units acceptable?

[Andrew Clark]

I purchased a boarded up home for 8K today. I have 65 days until it gets bulldozed by the city.

Details:
SFH
2/1
850 sqft
Cinderblock
Crawl space

I want to get it off the demolition list asap and to do this I need to have it meet minimum housing codes including heating.
I have researched baseboard heat and gas packs but today someone mentioned using window heating units to satisfy the city. I fully plan on putting in an entire HVAC system (have quotes averaging around $4500) but would rather get it off the bulldoze list asap just for piece of mind.
I am in Raleigh, NC. Has anyone used a window heating unit to satisfy SFH heating requirements?

Thanks,

Andrew
