The buildable land inventory (BLI) is an inventory of residential land that is still buildable or able to be developed. It uses available Geographic Information System (GIS) data to analyze and estimate where and how much additional development could occur, not necessarily what will occur. The number of residential lots that could be created, or single-family units constructed, is estimated based on the jurisdiction's current zoning and/or proposed future zoning (called "land use designation"). While the GIS model does not include commercial or industrial development potential, the report does contain information on land zoned and designated for these uses.

A BLI is a planning tool for making decisions related to the effectiveness of previously-adopted comprehensive plans and measures that could be taken to implement desired changes. The results of a BLI could influence decisions on such issues as watershed management, zoning and subdivision regulations, public facilities, and preservation measures. A BLI will not address the capacity of the natural systems or infrastructure because it is based on zoning that may or may not have been put in place with these considerations in mind. It also does not address the timing of potential development. It is important to reiterate that the BLI is a planning tool. It is not meant, nor even able, to be exact. The BLI does, however, provide Carroll County with a mechanism to analyze residential development capacity throughout the county.

Calculations were completed based on zoning and adopted land use designations, as of 2011. Figures based on zoning were run for each municipality and the unincorporated area of the county, and for each Priority Funding Area (PFA) and the non-PFA area of the county. The calculations based on adopted land use designations were run for each Designated Growth Area (DGA) and the non-DGA area of the county, and for each PFA and the non-PFA area of the county. As these numbers were based on adopted plans, the adoption of any plans since 2011 will likely change those numbers.
