Our Mission

Preconstruction is fragmented.
We're fixing that.

Every year, thousands of California homeowners and builders start projects without knowing what they need, who to hire, or in what order. They overpay for the wrong professionals, miss critical steps, and watch permits get rejected because no one told them what was required upfront. The preconstruction process is fragmented, opaque, and exhausting — and it hasn't changed in decades.

"Our mission is to give every builder a clear path from idea to permit — with the right professionals, the right guidance, and the right tools at every step."

— PlanLoft Team

👤
I want to build a 600 sq ft ADU in my backyard in San Jose. Where do I start?
🤖
Great project — ADUs in San Jose are permitted under SB 9. Here's your exact sequence:

① Site Survey② As-Builts③ ADU Design④ Structural⑤ Title 24⑥ Permit Filing

Start with a site survey — you'll need it for every step after. Budget $900–$1,600 in San Jose.
👤
Do I need a soils report?
🤖
For a standard 600 sq ft detached ADU in San Jose, a soils report is typically not required unless the lot is on a hillside, near a fault zone, or has known soil issues. Your structural engineer will advise after reviewing the site survey.
👤
What's the total cost I should expect for preconstruction?
🤖
For a 600 sq ft ADU in San Jose, expect roughly:

Survey $900–1,600 · Design $3,500–6,000 · Structural $1,200–2,000 · Title 24 $500–800 · Permit fees $8,000–14,000

Total: ~$14,000–$24,000 before construction starts.
