Permits and inspection in Garland
Permits go through Building Inspection, Main Street Municipal Building, 800 Main Street.
A permit is required for every electrical installation, and on a generator that means the transfer switch and the service tie-in. Where the gas line is touched it is a separate permit.
Garland publishes no generator-specific fee, and the residential permit adds a processing fee on top of the trade permits, so we confirm the total at the survey instead of quoting a figure off a schedule.
State preemption does not reach every Garland address. Texas Local Government Code § 229.102 bars cities from regulating a residential backup system of 50kW or less, but not where the city owns the electric utility, and Garland’s does. At those addresses the city’s own requirements apply. How the two statutes work.
Utilities that affect your install
Electric delivery in Garland is Garland Power & Light, the city's own utility, for most but not all of the city. On the municipal side the meter and the service drop belong to the same body that issues your permit, so the transfer-switch tie-in is agreed with the city. Off it, you are in the deregulated market with a separate delivery company. Your bill shows which side you are on.
Natural gas is Atmos Energy. If the meter cannot carry the generator on top of the furnace, water heater and other appliances, the utility has to upsize it, which is a separate request with its own timeline. How gas line sizing works.
Already have solar? It has to connect on the utility side of the transfer switch so the generator never feeds the inverters, and the disconnect and meter rules come from Garland Power & Light or Oncor Electric Delivery, whichever serves your address. Why, and how the main DFW utilities handle it.

Generator questions from Garland homeowners
How much does a whole house generator cost in Garland?
A typical 20kW Cummins system installed in Garland is estimated at $13,500 to $17,000, including the pad, transfer switch, permit and commissioning, with the gas line included as its own line item. Estimate only. Every installation is different; a site visit is required to determine whether your installation will cost less or more than this estimate. The RS20A unit itself is $5,925.25. Your figure depends on the distance from the generator to the gas meter and the electrical panel and on whether the gas meter needs upsizing, so it is fixed in writing after a free survey.
Do I need a permit for a generator in Garland?
Yes. Permits go through Building Inspection, Main Street Municipal Building, 800 Main Street. A permit is required for every electrical installation, and on a generator that means the transfer switch and the service tie-in. Where the gas line is touched it is a separate permit. We pull the permit and meet the inspector, and it is inside the installation quote.
Can Garland regulate my home generator install?
At an address served by Garland's own utility, yes. Texas Local Government Code § 229.102 bars cities from regulating the installation or inspection of a residential backup system of 50kW or less, but the statute does not limit a municipally owned utility within its own service area, so the city's rules still apply at those addresses.
Who provides gas and electric service in Garland?
Electric delivery is Garland Power & Light, the city's own utility, for most but not all of the city. Natural gas is Atmos Energy. The electric utility sets how the transfer switch ties in at the meter; the gas utility decides whether your meter can carry the generator's extra demand. Service territory does not follow city limits, so we confirm both from your bill before quoting.
