A Contractor You Can Actually Reach.
Most contractor horror stories start the same way — unreturned calls, vague answers, and surprises on the invoice. CoGeneral was built to be the opposite of that.
Best Price in town. No Overhead Markup
The big ADU firms carry in-house architects, engineers, and design staff. Every client pays for that overhead. We're construction-only — your money goes directly to the build, not their payroll.
Price Locked Before We Break Ground
Every contract includes a built-in contingency buffer. The price we give you at your walkthrough is the price on your final invoice. No change orders. No surprise invoices. Ever.
Always Reachable. Always Responsive.
Direct line to your project lead from day one — we answer calls and keep you updated every step of the way.
