Construction Guides

A build, an addition, a garage or an ADU is a chain of decisions — what the lot allows, what the code requires, and what each choice does to the number. These guides walk through the ones that matter most, cited throughout.

New Construction Cost in Columbus: Where the Money Goes
What a ground-up build costs in Columbus by finish tier, what moves a project between tiers, and the lot, site-work, utility, permit and design costs that sit outside the per-square-foot rate.
Cost & Budgeting
Home Addition Cost in Columbus: Bump-Outs to Second Stories
What additions cost in Columbus across four bands, why tying into an existing house costs more per square foot than building new, and what the foundation, roof and systems tie-in really adds.
Planning & Permits

Who to hire and when, how the Columbus Building and Zoning Services process works, why every suburb runs its own rulebook, and what the BZA and historic-district review layers add to a schedule.
Lot & Site Work

How to screen a vacant lot before buying it, what a survey and a geotechnical boring actually tell you, utilities versus well and septic, and why site work is a budget of its own.

About This Data

Why Most Cost Estimates Are Wrong

National averages don't apply here

Columbus has its own labor market, material suppliers, and permit requirements — and every suburb runs its own zoning and permit office. A build that pencils at $165/sqft nationally might run $195 here, or $150. It depends on your lot, your finishes, and who you hire.

Online calculators miss the real variables

Soil bearing capacity. Utility tap distance. A setback line that forces a redesign. These are the things that turn a $90K addition into a $130K addition — or stall a new build at the zoning board. The guides explain what to check before you get a quote.
