Why Columbia homeowners hire us.
A Columbia addition is counted on the Howard County single-family addition block once the parcel is confirmed in Howard County.
Columbia here is the Howard County census designated place, census place 2419125. The American Community Survey 2024 five-year estimates for that place show a median owner-occupied value of $497,400, a margin of error of $10,302, 26,665 owner-occupied units, a 64.8 percent owner share, and a median year built of 1983. That Columbia median is not a town median.
Howard County DILP is the building office for a Columbia addition on a Howard County parcel. The Columbia addition price is a free written estimate after a site walk of the parcel.
For this area, see Permits in Howard County: what to expect.

Questions about home additions in Columbia
How are Columbia addition rooms counted?+
Stories on the Columbia addition form are counted above grade only, and only for the addition. Bedroom count is the proposed bedrooms, and room count leaves out bathrooms and closets. A full bath on that form is a three-piece bathroom or larger, and a half bath is a two-piece bathroom. Both counts cover only the bathrooms the addition affects.
What square footage and drawings does the Columbia addition upload?+
Gross square footage is the total of every floor of the Columbia addition. The uploads are a plot plan drawn to scale, dimensioned, and located to the property lines, with the well or septic shown when the lot has one, and construction drawings sent to ProjectDox by invite, signed and sealed when that applies.
