Do I need a permit to install a generator in Houston?

Yes. Three permits are involved: building, electrical, and mechanical (gas). All of them go through the City of Houston Public Works Permitting Center. Grasten Power pulls every permit, schedules the inspections, and deals with any HOA review that applies (Memorial, Tanglewood, River Oaks, and West University all have HOA processes). What we need from you is a signed Notice of Commencement and a property survey. The normal approval window is 10 to 21 business days. Hurricane season sometimes stretches that out.
