In the really dry months, it can be helpful to water the perimeter of the foundation so the dirt doesn't crack below it.

Mostly suburban but close to everything slightly outside of the I-285 "Perimeter". 

"Debris under screened porch" will require someone getting on their belly and removing the debris with a rake, through one of the small service openings along the perimeter.

Go to the building department to get the codes but you'll basically have to dig down around the perimeter of the foundation of the shed and fill with cement, thus preventing the rats from making a home under your slab.

If old toilet is being reinstalled, clean outlet area well, remive existing caulk if present, and clean perimeter of toilet base with thinner.3.

I will have a 6ft rock perimeter around it.  3ft tall and a 3ft opening. 

However most of my tenants with pets do choose not to have the interiors of their apartments treated for rodents but we do put out bait stations around the perimeters of the properties and in the basements and sometimes in dropped ceilings and have never once had a pet become ill or poisoned.

Consider two-way audio capability at main entrance or perimeter where allowed (you do not typically record audio, but can activate it when "live"). 

If i gave you some perimeters, would you be able to set me up with an auto email for listings?

Putting a silicone caulk around the perimeter will help a lot but even then it's water RESISTANT.
