How it works
You are three steps away from your ADU
HaoBuild orchestrates every stage—intake, design, approvals, and construction—so you can focus on the lifestyle that comes with a new ADU.
Compare ADU proposals
We invite vetted designers, builders, and engineers to review your brief, submit cost ranges, and explain what makes their offer stand out.
Accept & build with confidence
Pick the partner you trust, we handle permitting, financing conversations, and keep your project on track until the ADU is move-in ready.
You’ve got questions. We’ve got answers.
FAQs from homeowners building ADUs through HaoBuild.
What is HaoBuild?
HaoBuild partners with homeowners to plan, design, and build accessory dwelling units (ADUs) that fit their property, budget, and permits.
Is it complicated to start an ADU?
We make it simple: upload your address, share site photos, and we coordinate consultants, permits, and build partners so you can focus on the outcome.
How much does it cost?
Getting started is free. You only pay once you choose a partner and sign agreements for each phase—design, approvals, and construction.
How do you ensure a great offer?
We match your project with multiple qualified teams, let them present their approach and pricing, and highlight which bids are most realistic.
Do I have to move forward if I don’t love the proposal?
No. You can walk away at any time before signing an agreement. We want you to feel confident about the schedule, budget, and builder before committing.
Can I watch the process?
Absolutely! We provide a project hub where you can review submitted plans, watch recorded design reviews, and see permitting updates.
