Under $150, easy to install and use, tenant can set their own code but landlord can retain the master and always have access, tenant can't lock themselves out, standard key for emergency backup, batteries last a couple years, etc.

Lightbulbs, batteries in smoke detectors is on them and written in the lease.You can really do whatever you want if it is written in the lease contract but bear in mind they don't own the home and won't care on certain things.

If you leave batteries there, that helps for that purpose since nothing else uses those batteries anymore.5.

The molestation charge could be a tack on charge during the battery.

Landlords can enter a tenant's property for a variety of reasons, including: Making repairs or replacements Responding to a tenant's request Removing unauthorized window coverings Preventing waste of utilities Changing filters, testing, or replacing smoke detector batteries Inspections Helping with an emergency inside the unit Posting a notice of eviction"Research your state laws because some of your comments indicate a lack of understanding of the landlord/tenant laws where you are operating (like threatening the tenants to keep the security deposit if they don't respond to you, I doubt that is actually a valid reason to keep their deposit, or evicting for late payments, or charging the tenants for your warranty repairs because you missed your 11 month inspection window which was your responsibility, and it looks like your lease says you can charge up to 18% interest for unpaid fees, is that actually legal?).

The mega site in Richmond, as well as Mt Vernon, will really change the landscape in these areas as they did in E-town when the battery plant came in play. 

It's a smaller town that is seeing growth from a billiion dollar EV Battery plant that Honda is building about 15 minutes away from it. 

I had all new smoke detectors with 10 year batteries put in, so I wouldn't have to worry about changing dead batteries - that beeping can ruin a guest's vacation. 

Maybe city is getting ready to go crazy on solar and needs a spot for a battery storage area. 

I have used Blink cameras, which are battery operated with great features, but they have to connect to a WiFi network.
