As of now, the Duterte administration permits POGOs here in the Philippines.

Just beware when you open the walls you open a bag of worms that many times need to be addressed if you are pulling permits(and I would pull permits, if you don't and something happens it would be gross negligence which may pierce the veil of protection of an llc, or void an insurance policy).

Originally a plumber by trade I have a hand for of guys and well connected to get any job done plus getting permits for renovation..

There is no permit required.

The LLC would use that note in conjunction with other financing to purchase, remodel, and sell a property.If that scenario is a prohibited transaction, are there services that would permit me to issue a note to another investor, and allow another SDIRA custodian to issue my LLC a note on an unrelated property?

On one of the houses, he pulled a building permit for plumbing, and that permit has expired before the bathrooms were finished so inspector did not do the inspection.I have another guy that can finish out the job, but he is not a GC and cannot pull permits.

I would like to add a bathroom to it and if permits can be acquired, a kitchenette.

I was wondering if anyone have experience getting retroactive permit in Orange County or City of Anaheim? 

Usually this type of unit will need a separate permit / CO (certificate of occupancy).

The hassle and costs of going through zoning and permitting can take 1-2 years, and the property sizes aren’t big enough to add an extra 1,000 sq ft.
