Updated 2026-10-03 · Which One Is Correct editorial team

Quick answer: Both forms are correct, but they mean different things. Use in the house when discussing the interior space. Choose at the house when referring to the general location or address. Context determines your choice.

The Short Answer

Both phrases are grammatically correct, yet they serve distinct purposes in English communication. You must choose based on whether you mean the interior space or the general location.

People confuse them because both prepositions indicate location. However, in implies containment within boundaries, while at suggests a point or address without specifying if you are inside or outside.
