"I have walked every day to your house."

Translation: Eu caminhei todos os dias até a sua casa.

Why are 'até' and 'a' needed here?

[erudis]

"Até" is the translation to "to", and "a" can be omitted if you want.

Should 'cada dia' be ok?

[peduzzi]

"Cada dia" is suitable to "Each day". In this case, "every day" can mean "todo dia" or "todos os dias".
