Survey, certification or both
Before a permit is issued, the city needs either a survey or a certification from a Texas-registered architect or licensed engineer. The city decides whether to accept the certification, and it does not replace a survey that other rules require.
Notice to the state goes in at least 10 working days ahead of a commercial building teardown, abatement in a public building or renovation above the state notice thresholds. In a public building, state-licensed people do the sampling and removal.
For residential buildings with several units, see apartments and condos.
