TL;DR. Before you pay an architect or a land-use attorney, know what Columbia actually allows on your lot. Buildability™ pulls Columbia's zoning, lot dimensions, setback envelope, overlays, and South Carolina state rules into a single feasibility answer. 20 seconds. First run is free.
What's typically possible on a Columbia lot
Most Columbia lots fall under a residential zone that permits one or more of: a new single-family home, an addition, an ADU, a detached garage, or a teardown-rebuild. What's actually feasible depends on lot size, existing structures, setbacks, FAR, height limits, and overlays like historic districts, flood zones, or hillside/slope rules. Buildability™ reads your specific parcel against Columbia's code — not a neighborhood generalization.
The hidden blockers to check first
The most common Columbia dealbreakers aren't obvious from the street: recorded easements, utility extension costs, wetland proximity, sewer capacity limits, or overlays that cap density below what the base zoning suggests. Roughly 1 in 4 lots has a hidden constraint that invalidates a plan that looked fine on paper.

Enter any Columbia address. Buildability™ pulls zoning, parcel dimensions, setbacks, FAR, height limits, easements, environmental overlays, utility access, and South Carolina state-level rules that apply.
