Essential Permits and Inspections Required for Home Generator Installation in Texas: Your Complete Guide to Safe and Legal Installation
When severe weather strikes Texas, having a reliable backup generator can mean the difference between comfort and chaos. However, before you can enjoy the peace of mind that comes with backup power, you must navigate the complex world of permits and inspections required for home generator installation in the Lone Star State.
Understanding Texas Generator Installation Requirements
Yes, a building, electrical, and possibly a plumbing permit will be required. Permits are required to ensure the generator is installed correctly and safely. The permitting process in Texas is designed to protect homeowners and ensure compliance with both state and local building codes.
Registered electrical contractors who wish to install a standby generator must apply for an electrical permit. This requirement applies across most Texas municipalities, though specific procedures may vary by location.
Essential Permits for Generator Installation
Texas homeowners typically need three main types of permits for generator installation:
- Building Permit: A building permit with a plan review is required to be pulled by a general contractor. This covers the physical installation of the generator unit itself.
- Electrical Permit: An electrical permit will need to be pulled by an electrician. This is required to ensure the electrician performing the work is registered with the City and meets the minimum state requirements for licensing and liability insurance coverage.
- Plumbing Permit: A plumbing permit will need to be pulled by a plumber. This is required to ensure the plumber performing the work is registered with the City and meets the minimum state requirements for licensing and liability insurance coverage. This applies when connecting natural gas or propane lines.
Required Documentation and Plans
Before permits can be issued, Texas municipalities require specific documentation. The plan will need to be submitted with the following information for review and approval before the permit can be issued: A copy of your home survey showing the location of the proposed generator.
Additional required documents include:
- Official Survey of Property indicating the location of proposed on-site generator, dimensions of the generator or generator housing, location, and orientation of equipment in relation to the existing gas meter
- Electrical plan providing one-line electrical drawings, load analysis, generator and transfer equipment specs, and tank component and specs
- A one-line electrical diagram showing how the automatic transfer switch will be wired into your homes electrical system indicating the type and size of both the electrical wire and conduit to be used
Critical Inspections During Installation
Texas requires multiple inspections throughout the generator installation process. The following inspections are required to be requested and items from the approved plans will be verified by the inspectors.
Key inspection points include:
- Foundation Inspection: Generator must be installed on a concrete pad or approved base that is a minimum of 3″ above the surrounding grade.
- Underground Electrical: Underground Electric Prior to backfilling – Verify Conduit, depth, warning tape (applicable to underground electrical systems)
- Gas Line Inspection: Underground gas piping required to have an inspection prior to backfilling. Underground gas piping shall have a minimum depth of 12 inches
- Final Electrical Inspection: Following installation, a request for inspection is sent to the municipality who will inspect the installed equipment including electrical and plumbing.
Safety and Code Compliance Requirements
Texas follows strict safety standards for generator installations. The City does regulate the distance the exhaust outlet on the generator must be from an opening into your home (such as an operable window, door, etc.). The exhaust outlet is required to be at least 5 feet from any opening in your home to help prevent carbon monoxide poisoning.
Properly labeled disconnect means (2017 NEC 230.85,110.21(B) ,445.18) are required to ensure safe operation and maintenance access.
Utility Coordination Requirements
Generator installation requires coordination with your utility company. Before starting the work, the electrician will need to send the make and model of the proposed automatic transfer switch to CenterPoint so they can verify it will be compatible with their equipment. The electrician will need to coordinate with CenterPoint to have the power turned off at your home so the automatic transfer switch can be wired in.
Timeline and Cost Considerations
A permitted job usually takes anywhere from 14 to 21 working days to complete. Sometimes, that can increase in different municipalities around the Greater Houston Area because there’s not electronic permitting in some areas where we actually have to hand carry documents down to the permitting authority. It can take up to 7 to 14 days to actually get a permit from certain municipalities.
Permit costs vary by municipality but typically range from $280 – $360 for the complete permitting package.
