Khaleel Reynolds died after touching the wires of an interior swimming pool light at North Villa Inn on the North Freeway at North Vista.
According to the lawsuit, the wires were left exposed even after failing inspections.
Harris Health officials said the pool should not have been open based on inspections from at least the past two years.

In 2018, the pool failed inspection twice: once in July and again in December.
The day after Reynolds died, Aug. 30, 2020, the pool failed inspection again.
The mother said she and her family lived at the motel, where she also worked.
She also said she was fired and kicked out after her son's death.
ABC13 contacted the motel for comment, but they have not responded.
