Triplex Plans

Triplex Plans & Development Packages

Three units on one lot only work when the plan squeezes every rentable square foot out of your zoning without tripping over parking or fire code. That's a custom-plan problem, not a stock-plan one.

Custom triplex plans arrive permit-ready in about two weeks and include per-unit floor plans, elevations, MEP layouts, a parking/site plan, CAD/DWG files and a cost estimate.

Townhouse vs. stacked triplex

Townhouse triplex — three attached units, each with its own entrance and small yard; reads as three homes and is easiest to later sell as individual townhomes.
Stacked triplex — two-over-one or a garden-level unit under two; fits a narrow lot and pushes per-unit cost down by sharing more structure.
Your zoning's parking ratio and setbacks usually decide which is buildable — so we start from your lot dimensions and work backward to the layout that maximizes rent.

Built for the numbers, not just the drawing

Every triplex package is drawn with the exit in mind: a unit mix that matches local rental demand, mechanical layouts that keep utility runs short, and a site plan that satisfies parking without wasting rentable land.

You get CAD/DWG files, 3D renders, and an RSMeans-based build-cost estimate so you can take a real number to a lender before you spend on engineering.

Frequently asked questions

How long does a triplex plan take?+

A custom triplex plan set is typically ready in about two weeks, including revisions. Repeatable multi-lot designs are quoted per project.

Will a triplex plan fit my parking requirements?+

Yes — we design the site plan to your jurisdiction's parking ratio and setbacks from the start, so the layout you approve is one that can actually be permitted.

Do you provide a cost estimate with the plans?+

Every triplex package includes a build-cost estimate based on RSMeans 2026 data, adjusted to your location, so you can start financing with a real number.

Can the triplex be sold as individual units later?+

A townhouse-style triplex is the easiest format to condo-ize or sell as separate townhomes down the line; we can design with that exit in mind.
