Where Detectors Are Required
Texas building code and NFPA 72 require smoke detectors in specific locations throughout your home. For new construction and remodels, all detectors must be hardwired with battery backup and interconnected.
- •Inside every bedroom
- •Outside each sleeping area (hallway)
- •On every level of the home (including basement)
- •CO detectors near gas appliances and attached garages
If you are selling your home, many inspectors and buyers require functioning, code-compliant detectors. C.S.W. Power Solutions provides fast detector upgrades to help your home pass inspection.

Smoke Detectors and Your Electrical System
Hardwired smoke detectors require dedicated wiring from your electrical panel. If your home has older wiring, detector installation is often combined with a whole-house rewire for the most cost-effective approach. Smoke detectors are also a standard part of any remodel or damage restoration project. For maximum home safety, we recommend pairing smoke detectors with surge protection and a standby generator to keep your safety systems running during power outages.
