San Diego ADU Match is a matching service for San Diego County homeowners planning an accessory dwelling unit. You describe your project once. We match you with one licensed local ADU builder who works in your city — and only that builder. Your details are never sold to a list or shared with other builders. We are a matching service, not a contractor: we do not build, design, or permit ADUs.
Start your match request For builders: the pilotThree steps, and one contract rule that protects you: any building contract is signed directly between you and your builder, and you pay the builder directly. We are never in the middle of the money or the work.
The form below takes about five minutes: your property city and ZIP, the kind of ADU you want, your purpose, budget band, financing status, and timeline. That is what makes a match real instead of random.
One licensed San Diego County ADU builder whose stated service area covers your property. Before or as that builder first contacts you, we confirm their name and CSLB license number to you, so you know exactly who is calling and can verify the license at cslb.ca.gov.
By the call or text you consented to. Feasibility, design, pricing, and the contract are between you and the builder — we never quote prices, estimate your project, or negotiate terms, and we are not the builder's agent or salesperson.
Changed your mind? You can revoke your consent at any time — reply STOP to any text, or use the privacy options in our privacy policy. Revocation is passed to your matched builder.
We are not a contractor and we never quote or estimate a price for your property. What we can do is show you the ranges San Diego builders themselves publish, and the basic rules picture, so you start the builder conversation informed.
Published ranges from San Diego ADU builder guides (2026). Your project can land outside them — lot, size, finishes, and utility work move the number a lot.
| ADU type | Published range |
|---|---|
| Junior ADU (JADU), inside the existing home | $50,000 – $100,000 |
| Garage conversion | $100,000 – $210,000 |
| Detached new build | $300,000 – $450,000+ (about $375–$600 per sq ft) |
These are educational ranges published by builders, not a quote, estimate, or offer for your project. Only a licensed builder who has looked at your property can price your ADU.
Areas we match in:
Free, and it takes about five minutes. Your answers go to exactly one matched builder, with your consent — nobody else.
San Diego ADU Match sells one thing: exclusive, consent-documented ADU leads from San Diego County homeowners — property city and ZIP, ADU type, purpose, budget band, financing status, timeline, and written consent to be contacted. Not shared lists, not recycled directory scrapings. The pilot exists so you can judge the quality on five leads before any ongoing arrangement.
$150 per lead. The pack ends at 5 delivered leads.
This is a pilot and homeowner flow starts from zero. Expect first leads within 30–45 days of payment. If that timing does not work for your pipeline, do not buy the pilot — we would rather lose the sale than oversell the schedule.
How to join: the pilot is being offered to a small number of San Diego County ADU builders. If we have contacted you about it, reply to that email — Operations, San Diego ADU Match. Payment is by invoice or payment link before the first lead is delivered.
Every delivered lead contains, at minimum: homeowner name, mobile phone, and email; preferred contact method and best time; property city and ZIP; ownership (owner or in escrow — renters are never delivered); property type; ADU type wanted; purpose; budget band and financing status exactly as the homeowner stated them; timeline; and a timestamped consent record — the exact wording the homeowner agreed to, including the disclosure that builders pay us a marketing fee. A lead missing budget or timeline is a nurture contact, and it is never billed.
Report an invalid lead within 5 business days of delivery with a one-line reason, and it is replaced free or credited. The categories:
Not invalid (billable): the homeowner is also talking to other builders; the budget is real but lower than you prefer, where the band was disclosed exactly as stated; the homeowner goes quiet after delivery (unresponsive is not invalid); or the homeowner decides not to proceed after a genuine conversation.
Our side of the paper: the fee is a flat marketing fee — never a percentage of, and never contingent on, any signed contract or project value. San Diego ADU Match is an independent matching service: not your agent, employee, or salesperson, and not a contractor. Homeowner contracts and payments run directly between you and the homeowner. Pilot builders warrant an active CSLB license in the proper classification, agree to honor homeowner revocations and do-not-call obligations, and agree to use lead data only for that homeowner's project and never resell or share it onward. We check each builder's CSLB license before the first lead is delivered.
