Townhome & Rowhouse Development Plans

Townhomes and rowhouses are the sweet spot of build-to-rent and for-sale infill: far more units per acre than detached homes, without the cost and complexity of a mid-rise. We design the whole project — the attached-row structure, per-unit plans, party-wall fire separation, parking and the full site.

In 2026 attached townhomes run roughly $150–$250 per square foot to build, or about $180,000–$400,000 per unit depending on size, finish and region. A clean, permit-minded plan set is what keeps a multi-unit project financeable and moving.

Plan density and zoning early

Townhome projects live or die on local density, setback and parking-ratio rules. We lay your project out permit-minded from day one — so you are not redrawing the site after a rejection or losing a unit you were counting on.

Townhome build cost per unit (2026)

Unit type	Typical cost	Notes
2-bed townhome	$180k – $280k	~1,100–1,500 sq ft, attached
3-bed townhome	$260k – $400k	~1,600–2,200 sq ft, attached

Frequently asked questions

How many units can you plan?+

From a small 2–4 unit row to 20+ unit for-sale or build-to-rent communities. Larger projects are scoped individually.

For-sale or build-to-rent?+

Both. We design fee-simple townhomes for sale and build-to-rent rows for investors, and plan the site and utilities accordingly.

Do you handle party-wall fire code?+

Yes — rated party-wall and fire-separation assemblies between units are core to the plan, drawn to your local code.

What about parking ratios?+

We design to your jurisdiction parking ratio — attached garages, driveways and guest parking — and flag it early so density holds up.
