Webb County Development Starts With a Planning Determination

For a project on Webb County land outside city limits, start with the Development Determination Application. It comes before the other development forms. As of September 2026, the fee list shows $30 for residential or non-residential work and $100 for commercial work. Bring recorded proof of ownership and a copy of ID.

The county uses that first form to tell you which approvals the work needs. The next step may be a floodplain permit, septic approval, a utility certificate, or a plat. An address letter alone does not let you build.

Take the parcel and planned use to Planning before ordering a utility tap or starting work. Inside Laredo city limits, start with city planning. Ask which other offices must sign off too.
