We Turn Backyards
Into Wealth-Building Assets.

Build With A Plan exists to make ADU ownership accessible. We handle the design, permits, financing, and builder matching — so you can focus on the return.

A Done-For-You ADU Service Built for Homeowners

Most ADU companies make you coordinate between architects, engineers, permit runners, lenders, and contractors. You become the project manager of a process you've never done before. Build With A Plan was designed to eliminate that.

We handle the full scope: from the free AI feasibility study that confirms your property qualifies, through custom design, construction documents, permit coordination, financing introductions, and vetted builder matching. One flat fee. One point of contact.

We've delivered 50+ ADU projects across California, Texas, Arizona, Florida, Oregon, Washington, and Colorado. 98% permit approval rate. Every client supported from first feasibility call to builder handoff.

What We Stand Behind

Free Feasibility First

We prove your property qualifies before you invest a dollar. AI-powered analysis checks zoning, setbacks, buildable area, and ROI — in 48 hours, free.

One Flat Fee

No hourly billing. No discovery phases. No surprise invoices. $6,000 covers design, permits, financing, and builder matching.

Permit-Ready Standard

We don't deliver "design intent drawings." We deliver construction documents that get permits approved — 98% of the time on the first submission.

Builder Matching

We connect you directly with a vetted, local ADU builder. Your contract is with the builder — full cost transparency and accountability.

Industry-Standard Tools. Professional-Grade Output.

We produce every drawing set using the same professional-grade software used by top architectural firms across the US. Your building department knows these drawing formats. Your contractor knows how to read them.
