Local services in Preston Hollow

Permits go through the city's DallasNow portal, and a contractor pulling one must be registered with the City of Dallas. A homeowner can pull a permit for their own homestead without registering, as long as nobody is paid to help.

Lot size matters for trees. Under the city's 2019 tree manual, Dallas's Article X tree-removal division doesn't apply to lots under two acres with a single-family or duplex use, so on a lot of two acres or more, ask the city about current code before a crew cuts. Work in the 100-year floodplain needs a city floodplain fill permit.

Dallas Water Utilities supplies water. As of October 2026 the standing schedule allows sprinklers twice a week, never between 10 a.m. and 6 p.m., and a drought stage could tighten it. In ZIP 75225, power arrives over Oncor's lines from a retail provider you choose, and brush and bulky pickup comes once a month, up to 10 cubic yards.

Two services have Preston Hollow pages: dentists and realtors. For trades, use the citywide Dallas pages, such as tree service and roofers, since the same permits and registration apply. The Town of Highland Park is a separate town with its own rules.
