Almost always yes, if the property is already platted and you want to change the lot lines. The question that actually costs money is which kind, because one of them adds a public hearing and mailed notices, and takes about six weeks from submittal to hearing.
A replat of a platted lot is normally a C2R. If the original plat or a predecessor deed restricted the property to single family use, it becomes a C3N instead: a public hearing, notices mailed to every owner within 300 feet of the plat boundary, and $707.34 in additional City fees. From submittal to hearing the clock is 39 days on the clean path.
A Class 1 amending plat can remove an interior lot line administratively, with no Planning Commission meeting, which is much faster when it fits. It cannot add lots, add area, or change building lines.
Across the 17 Planning Commission meetings from January 8, 2026 to August 20, 2026, about 7 in 10 applications were approved at the first meeting they were eligible for. About 1 in 5 did not reach that first meeting, losing at least two weeks before the Commission saw them. Plats that need a public hearing are left out of both figures, because their notice window makes the first meeting impossible by design. The City's data does not say why a plat arrived late.
Every read queries the City of Houston's own GIS layers rather than a generic parcel database, and it separates what it confirmed from what it could not. Where a layer does not answer, the report says so instead of filling the gap with a default. A confident wrong answer about whether your lot can be split is worse than no answer, because you would act on it.
Private deed restrictions are recorded with the county. We do not read them, and a title report is how you confirm them.
