Otherwise google “building material surplus” / scratch and dent” and your ZIP code

@Pete Panci zoning and building code for ADU's is tricky here.  

These are professionals with additional training and a stricter code of ethics.

You can usually go on the housing authority website and look at the allotted rent amounts per zip code per county.  

However. as long as you have a line, neutral, and ground wire (3 prong fittings), installation is cheap.NEC Guidance: https://www.ecmweb.com/national-electrical-code/code-basics/article/20898894/nec-requirements-for-groundfault-circuit-interrupters-gfci

In witch zip code is the property?

You can try contacting your jurisdiction about your specific case or you can try reading through your state’s Building Code on what’s allowed for Alterations.

Unless you've got something unusual <$500.I'd be looking for stuff like:1) Major CapEx - Life of roofs and siding and paving and plumbing2) Moisture invasion ANYWHERE since this gets more expensive the longer you wait3) Making sure stuff (like remodels and wiring) is up to code. 

The Collateral paragraph says: All tangible and intangible personal property, including, but not limited to: (a) inventory, (b) equipment, (c) instruments, including promissory notes (d) chattel paper, including tangible chattel paper and electronic chattel paper, (e) documents, (f) letter of credit rights, (g) accounts, including health-care insurance receivables and credit card receivables, (h) deposit accounts, (i) commercial tort claims, (j) general intangibles, including payment intangibles and software and (k) as-extracted collateral as such terms may from time to time be defined in the Uniform Commercial Code.

It's likely a code- compliant installation, however.
