Flexible Financing for ADU in San Francisco
An ADU is one of the largest investments you’ll make in your San Francisco property, and the financing question stops a lot of good projects before they start. Sutton ADU San Francisco has worked with homeowners across the city since 2006, so we’ve seen every payment situation you can imagine. Call (831) 272-7212 and we’ll walk you through what’s possible for your lot, your budget, and your timeline. The honest answer is that most homeowners here can move forward with a plan that fits without stretching themselves thin.
Payment Options We Offer

Financing Plans
We connect San Francisco homeowners with financing programs that work for construction projects like detached ADUs, garage conversions, and room additions. These aren’t one-size-fits-all products. Depending on your situation, you may be able to spread payments over a longer term, keep monthly costs predictable, or structure draws that align with construction milestones. Our team has guided hundreds of local projects through this process, and we’ll help you find an approach that matches your equity position and cash flow.
Major Credit Cards
Plenty of our clients in neighborhoods like Sunset, Richmond, and Noe Valley prefer to put deposits and progress payments on a card, especially for smaller scopes like a Tuff Shed conversion or a room addition. You earn points, you get the standard card protections, and payment is immediate. We’ll confirm what portion of the project can run through cards versus what needs to be check or wire, so there’s no confusion when a draw comes due.
Cash or Check
For homeowners who have saved for the project or pulled equity from a refinance, cash and check are the simplest paths. There are no application forms, no waiting periods, and no follow-up paperwork. We’ll give you a written payment schedule up front, so you know exactly when each chunk is due and what it covers. Many clients pair this with staged payments tied to inspections, which keeps everyone honest.
Up-Front Written Pricing
Every Sutton ADU project starts with a written price before any work begins. That’s a Threshold Standard rule, not a courtesy. The number you sign off on is the number you’ll pay, whether the project is a detached ADU in the Outer Sunset or a second-story addition in Bernal Heights. If site conditions change something, we tell you first and adjust in writing. No surprise invoices at the end.
Simple Application Process
The financing conversation starts with a phone call to (831) 272-7212. We’ll ask about your property, the ADU size you’re considering, and whether you’ve pulled any numbers together yet. From there, we have a short pre-qualification conversation that usually takes under fifteen minutes and gives you a realistic sense of what monthly payments might look like. No hard credit pull at that stage. Once you know your range, you pick the plan that fits and we move forward with a written quote. For most San Francisco homeowners, the whole thing from first call to clarity takes less than a week.
