Compare at least two quotes for whole-house upgrades. Rental property compliance packages in San Antonio start from $200.

Check online reviews on Google and trade platforms. Confirm the installer holds appropriate licences for your state or territory — hardwired alarms require a licensed electrician. For rental properties, ensure the provider can issue a written compliance certificate. Ask whether they carry public liability insurance and confirm warranty terms on the alarms installed.
