I had the home inspection done yesterday during the option period.

I suggest you simply stick to a letter stating the law, timelines, and the fact that the inspections which should have been done by the landlord and given to you were not done in compliance with CA law.

Standard procedure is to post your state-specific notice of lease violation, and then perform a follow up inspection at the expiration of said notice, to determine if the violation is cured. 

Per our contract the seller was supposed to fix plumbing, electrical and structural issues that we found in the inspection.

Your rent is in your account the 1st of each month, Section 8 inspects the house yearly, and tenants don't want to do anything that would cause them to lose their voucher.

Hi Ting,I've had Pest Control companies that layed down a DMZ of sorts outside the buildings.Fire ants, ants, and a lot of other crawlies seem to stay away from the DMZ area--keeping them out of the house.I've had them do it in the pouring rain and on nice days.Maybe they do something like that in your area.If it's a problem, you can scheduled ongoing service for it--where they will come out and re-apply.Or you could pass the info on to the renter--it's less costly then her hiring an attorney (unless she is govt subsidized and gets free attorneys via legal aid).They also do a building inspection inside and out--looking for entry points that need to be "Repaired", but ants get in through the smallest cracks.If you have a slab foundation, they may be under the slab and coming through a crack in it--exterminators can handle that.One or two phone calls will get you a quick price, and being there when it happens to take notes on where the tech says to repair to prevent other insects coming in might be a smart move.I've seen long lines of ants outdoors coming up a metal handrail to an apartment and going into a tiny space at the corner of a window and into the apartment. 

If I were to go this route would/should I get a home inspection done? 

My cash deals take 2 weeks for title work and inspections to satisfy.
