It ensures uninterrupted electricity and peace of mind during emergencies. [READ MORE](https://guardianhomegenerators.com/blog/how-whole-home-backup-generators-work) ##### [QUESTION Do you get my city permits? Do I need them?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse2-dnd_area-module-6) Yes, all of our whole-home generator projects are permitted with your city, and we handle the entire process.  This ensures the highest quality installation, and customer protection, and ensures there are no issues with your homeowners' insurance.  If an installer ever says, "you don't need city permits, we do this all the time" RUN.  This is not the installer you want to work with. While rare, you don't want to get caught by the city for installing without a permit as this can delay your project by weeks or months as well as unexpected costs and fines.  And, while also not common, having major work to your home without permits can void your homeowners insurance.  [READ MORE](https://www.rocketmortgage.com/learn/buying-a-house-with-unpermitted-work) from RocketMoney ##### [QUESTION How long does the permitting process take?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse3-dnd_area-module-6) A process that used to take up to several weeks is now completed in a few days. While many companies still rely on traditional city wait times, **Guardian Home Generators** was an early adopter of the Texas SB 1202 pathway. This law allows us to use certified, independent third-party experts for plan reviews and inspections, effectively clearing the municipal hurdles that cause delays for other installers. You get the same, or often higher, safety standards, but on a predictable, accelerated timeline that gets your home protected faster. [Read more about how Guardian Home Generators uses TX SB 1202 to benefit you.](https://guardianhomegenerators.com/texas-law-sb-1202-is-making-generator-installs-easier) ##### [QUESTION Can my HOA prevent the installation of a standby generator?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse4-dnd_area-module-6) In Texas, an HOA cannot prevent a homeowner from installing a permanent whole-home standby generator.  They can require it to be screened to maintain the neighborhood's aesthetics, but they cannot prohibit or dictate its location if it increases project costs by 10%. *[Texas Property Code - PROP § 202.019](https://statutes.capitol.texas.gov/docs/PR/htm/PR.202.htm). Standby Electric Generators:* *(b)  Except as provided by this section, a property owners' association may not adopt or enforce a dedicatory instrument provision that prohibits, restricts, or has the effect of prohibiting or restricting an owner from owning, operating, installing, or maintaining a permanently installed standby electric generator.* ##### [QUESTION Will you work with my HOA?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse5-dnd_area-module-6) Each HOA has very unique processes.  We will provide you with all of the necessary documents you will need.  Please note, this is one of the top causes of delays for a project.  Some HOAs only meet once per month to review requests.  We'll work with you to ensure you have everything you need. ##### [QUESTION I don't have natural gas, can I still install a generator?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse6-dnd_area-module-6) Yes, absolutely.  Each Generac home backup generator we install can be configured to run on either LP (Liquid Propane) or NG (Natural Gas).  During your initial consultation, we’ll review your fuel options in detail. Please note: these are not your standard gas grill propane tanks. The most common configuration within city limits is two vertical 120-gallon propane tanks that can be placed directly next to your home.  If space allows, a single horizontal 250-gallon tank may be used. [READ MORE](https://guardianhomegenerators.com/blog/propane-when-natural-gas-isnt-available-for-your-whole-home-backup-generator) Liquid propane has many advantages over natural gas. ##### [QUESTION How long will it take to get my generator?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse7-dnd_area-module-6) From deposit to the final installation and homeowner walk-through the process generally takes about two to three weeks.  In rare cases, it may take a month.  The installation process is one to three days, depending on several factors outside of our control.  The permitting process and/or HOA approval (when applicable) are often what take the longest amount of time. ##### [QUESTION What areas do you service?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse8-dnd_area-module-6) Based in Grapevine, we proudly serve the entire Dallas–Fort Worth Metroplex. While our reach spans the DFW area, we place a special focus on the communities closest to home. By prioritizing our neighbors, we’re able to maintain the highest quality of work, deliver faster response times, and keep costs competitive—all while staying deeply connected to the community we call home.  We love serving our neighbors in Northeast Tarrant County, including: [Grapevine](https://guardianhomegenerators.com/service-areas/grapevine-tx-whole-house-backup-generators), [Colleyville](https://guardianhomegenerators.com/service-areas/colleyville-tx-home-backup-generators), [Southlake](https://guardianhomegenerators.com/service-areas/southlake-tx-home-backup-generators), [Trophy Club](https://guardianhomegenerators.com/service-areas/trophy-club-tx-house-backup-generators), [North Richland Hills](https://guardianhomegenerators.com/service-areas/north-richland-hills-tx-home-backup-generators), [Keller](https://guardianhomegenerators.com/service-areas/keller-tx-home-backup-generators), [Hurst](https://guardianhomegenerators.com/service-areas/hurst-tx-home-backup-generators), [Euless](https://guardianhomegenerators.com/service-areas/euless-tx-home-backup-generators), [Bedford](https://guardianhomegenerators.com/service-areas/bedford-tx-home-backup-generators), [Flower Mound](https://guardianhomegenerators.com/flower-mound-tx-home-backup-generators), [Coppell](https://guardianhomegenerators.com/coppell-tx-generator-installation-service-maintenance), Carrolton, and adjacent communities. ##### [QUESTION How much does a whole-home standby generator installation cost?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse9-dnd_area-module-6) There are too many factors to provide an online cost.  The most common generators we install are 18kw - 28kw.  The generator + Automatic Transfer Switch price range is $6,800 - $9,200.  Installation costs vary greatly, with generator location generally being the largest factor.  The total price with all permits, labor, materials, generator, and ATS for a typical install in a 1,500 to 3,500 sq ft home is generally $13,500 - $16,500.  Surpassing $20,000 does happen, but it's rare.  [Click here for a full breakdown](https://guardianhomegenerators.com/blog/how-much-does-a-whole-home-generator-cost-in-north-texas) ##### [QUESTION Where will the generator go and how large is it?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse10-dnd_area-module-6) A whole-home backup generator is slightly larger than an AC unit.  The generator must be 5' from any opening on the home (operating windows/doors, soffits, or vents), it must have 3' of clearance on the front and each side, 18" behind, and 5' above.  It must be at least 3' from any other appliances (AC, external water heater), electric meter, and gas meter.  If propane is used, it must be 10' from the propane tank(s).  Some cities allow the unit to be placed near the fence/property line; other cities (like Euless and Ft Worth) require it to be 5' from the property line.  Schedule a free site evaluation today!   ##### [QUESTION How loud will my backup generator be?](https://guardianhomegenerators.com/whole-home-generator-questions-answers#collapse11-dnd_area-module-6) A generator sounds roughly like a lawn mower.  Generators are very commonly located next to the garage so many homeowners will barely hear anything inside the home.  Others may hear a faint and constant hum inside the home.  Again, similar to someone mowing the lawn. ### Featured Blogs [![How much does a home generator cost](https://guardianhomegenerators.com/hubfs/Whole-home%20generator%20cost%20and%20installation.png)](https://guardianhomegenerators.com/blog/how-much-does-a-whole-home-generator-cost-in-north-texas) - [Brad Nash](https://guardianhomegenerators.com/blog/author/brad-nash) - October 10, 2026 ### [How much does a whole home generator cost in North Texas?](https://guardianhomegenerators.com/blog/how-much-does-a-whole-home-generator-cost-in-north-texas) What Goes Into the Cost of a Generator Installation?
