For Contractors

Walkthroughs with reviewed homeowners — not raw lead lists

United Build Partners is a homeowner advisory service for accessory dwelling units. We help homeowners understand their options, get organized, and prepare for real conversations with a contractor. When a project fits your experience and service area, we coordinate an introduction and arrange a walkthrough with a homeowner who already knows roughly what they want to build.

What we do, and what stays with you

United Build Partners handles the early part of an ADU project. We market to homeowners, help them understand the process, review their property basics, and coordinate scheduling. We are not a construction company, an architect, an engineer, a lender, or a government agency. We do not bid, sign construction contracts, direct your crews, or collect construction payments.

Everything that makes you the contractor stays with you. You run your own feasibility review, prepare your own proposal, set your own pricing, sign your own agreement directly with the homeowner, pull permits, manage the build, and stand behind your work. Our job is to bring you a prepared homeowner and then step out of the way.

How introductions work

We review each homeowner request before anyone hears about it, confirming basics like ownership, general location, project type, budget range, and timeline. When a project is a genuine fit for your experience, capacity, and service area, we coordinate an introduction and arrange a walkthrough.

When appropriate, homeowners may compare a small, curated group of contractor options, generally no more than three. Homeowners are always free to choose, to seek other bids, or to decide not to build at all. Introductions are not exclusive unless we assign exclusivity to you in writing, and we do not promise a territory or a set number of introductions.

Who fits the network

We are building a small, selective network rather than a large directory. The contractors who do well here communicate quickly, arrive prepared, and treat homeowners with patience during a confusing decision. In practice that means a few consistent standards.

  • Active license and appropriate insurance. A CSLB license in good standing for the work you offer, plus general liability and workers' compensation coverage appropriate to your operation.
  • Relevant residential and ADU experience. Completed projects you can show and talk through, not just a portfolio slide.
  • Prompt, professional communication. Homeowners judge the whole experience by how you follow up. Contractors who go quiet on homeowners do not stay in the network.
  • Clear, written proposals. Honest scope, realistic timelines, and documentation homeowners can compare line by line.

Where we operate

Current service area

We accept homeowner requests across select Los Angeles, Orange, San Bernardino, and Riverside County communities, with San Diego County planned next. Introduction volume in any territory depends on homeowner demand and project fit. We would rather tell you that plainly than promise volume we cannot verify.

Frequently asked questions

We are a homeowner advisory and contractor-matching service focused on ADUs and related residential projects in Southern California. We market to homeowners, educate them, review their property basics, and coordinate introductions. We are not the construction contractor and do not replace your own feasibility review, bid, contract, permitting, or project management.

We review each homeowner request and, when a project fits your experience, capacity, and service area, we coordinate an introduction and a walkthrough. Assignment depends on homeowner demand, geography, scope, your responsiveness, and network needs. It is not a fixed rotation or a guaranteed territory.

Not by default. When appropriate, a homeowner may compare a small, curated group of contractor options, generally no more than three, and is always free to choose. An opportunity is exclusive only if we assign exclusivity to you in writing.

No. We do not promise a minimum number of introductions, a territory, a close rate, or that any homeowner will hire you. Introductions depend on real homeowner demand and how well a project fits your work.

You and the homeowner, directly. United Build Partners is not a contractor and is not a party to the construction agreement. We do not negotiate terms, set your pricing, or sign anything on either side's behalf, and construction payments go to you, never to us.

Yes, subject to licensing, disclosure, and quality requirements. You remain responsible for your own team and the resulting contracts.

We review your submission against the same standards we describe above. If it looks like a fit, we reach out to talk, verify the basics, and walk you through formal onboarding before anything is signed. Submitting interest is not an application for a guaranteed position and does not by itself place you in the network.
