Gray water is hazard so may need sanitization of all areas with footprints.7>Have water turnoff at the property bcoz you do not want tenant to use water.

I do see that masonry cleaning/chemical wash (the prep work) - "may require an air pollution control permit from the Environmental Permitting and Inspections Section of the CDPH"And then digging further I see there's also a separate Architectural Surface Cleaning Permit could be required.Anyone have experience with this?

The local Department of Health and Environmental Control can usually provide guidance relative to which contaminants, if any, are prevalent in your project area.

Company states the following:" Due to the presence of damaged asbestos containing materials and debris, a Procedure 5 (P5) cleanup plan is required to be generated by a Certified Asbestos Consultant (CAC), such as JLM Environmental, and approved by the SCAQMD prior to asbestos abatement in accordance with SCAQMD Rule 1403."

Pool and solar could just come later but no point in not involving them from the beginning so they can look at your footprint and orientation and start designing something that will work for you. 

If it's a complete gut job or tear down, add on etc. for sure, but normal cosmetic or mechanical upgrades without changing the "footprint" they don't want to do it. 

I actually just made contact with a broker who is looking to expand their footprint in OK, so leaving it alone for the time being may be our best option.

But again, because the footprint of the town is so small, most houses that have an Indian Hills postal address are actually in unincorporated Jeff Co.)Bailey, as said above, is in Park County, which is -- for now -- totally open to STRs.

As someone with farming, gardening, hunting, and rural-land-specific real estate sales experience, I recommend putting some thought into what sort of footprint you'll need for crops, livestock and infrastructure to be sure you are comparing properties that are actually usable, especially if you expect to depend on revenue from your growing operations.A small garden can work in a lot of places, but raising crops and livestock requires space, gentler land, cleared ground, sunlight, and access to a water source.

1) glad you know your error now but I guess it's about minimizing damage now; in future I think anytime there's an environmental question beforehand about a property the ideal situation is you get what's called IIRC a 'no further action' letter before purchase otherwise pollutants in ground can be pursed by lawyers even though property has been sold to another owner 2) if you have 2 widely varying quotes, I think you need to drill down deeply into what both quotes are and are not covering and then probably get a 3rd quote with as much detail as possible to also compare
