Flexible Financing for ADU in Ontario
Call (951) 577-3472 to talk through how an ADU fits your budget. At Ellery ADU Studio Ontario, we’ve seen too many Ontario homeowners delay a garage conversion or detached unit because they assumed financing would be complicated. It doesn’t have to be. Nadia Ellery and our team walk you through the options that exist for your specific project, and every conversation starts with our written price guarantee under Haven Standard Clause 1 - no surprises, no hidden fees, no “call for a quote” runaround.
Payment Options We Offer
Financing Plans
Third-party financing is available for qualified Ontario homeowners building ADUs, garage conversions, or junior ADUs. We work with lending partners who understand construction timelines and permit schedules, so your funding aligns with project milestones rather than demanding full payment before a shovel hits the ground. Terms vary based on credit history and project scope; we’ll connect you with a representative who can explain current programs without pressure.
Major Credit Cards
We accept Visa, Mastercard, American Express, and Discover for deposits, progress payments, or full project settlement. This option works well for smaller projects like interior conversions or for homeowners who want to leverage existing credit lines and rewards programs. Card payments process through our standard invoicing system with the same documented photo record attached to every transaction.
Cash or Check
Some of our Ontario clients prefer traditional payment by personal check, cashier’s check, or wire transfer. This often applies to homeowners who’ve been saving specifically for an ADU project or who are drawing from a home equity line already established. Under Haven Standard Clause 1, your written price locks at contract signing regardless of payment method - the total doesn’t shift because you chose one channel over another.
Up-Front Written Pricing
This is the foundation of every payment conversation at Ellery ADU Studio Ontario. Before any work begins, you receive a written, line-item quote covering design, permitting, construction, and site prep. That price is the price. Our 365-Day Done Right Promise backs it in writing. We’ve completed over 900 ADUs since 2015, and every single one started with this document. No homeowner in Ontario’s Bon View neighborhood or the newer builds south of the 60 has ever faced a surprise invoice from us.
Simple Application Process

Getting clarity on financing takes three conversations, not three weeks.
Step 1: Talk to us about your project. Call (951) 577-3472 and a live person answers - no voicemail queue, no callback that doesn’t materialize. We’ll ask about your property in Ontario, whether you’re considering a garage conversion near Guasti or a detached ADU closer to the airport corridor, and what your rough budget looks like. Nadia Ellery or a senior team member will flag any site-specific considerations that affect pricing, like slope, utility distance, or existing foundation condition.
Step 2: Quick pre-qualify conversation. If financing interests you, we’ll connect you with a lending specialist for a brief discussion about your situation. This isn’t a formal credit pull or an invasive application. It’s a reality check: here’s what programs exist, here’s what documentation you’d need, here’s a realistic monthly range if you qualify. Most Ontario homeowners know within one business day whether financing is viable for their ADU project.
Step 3: Choose your plan and lock your price. With financing clarity in hand, we finalize your written quote under Haven Standard Clause 1. You choose the payment structure that fits, sign the contract, and we move into design and permitting. Your price is fixed. Your photo documentation begins on day one. And your 365-Day Done Right Promise is already in writing before the first site visit.
Frequently Asked Questions
Yes, third-party financing is available for qualified homeowners through lending partners we work with regularly. These programs are designed for construction projects with milestone-based disbursements, not lump-sum demands before work begins. Call (951) 577-3472 to discuss whether financing fits your garage conversion, detached ADU, or interior conversion project - estimates are free.
You’ll typically need proof of income, a recent credit report, and documentation of your property value in Ontario, such as a mortgage statement or recent appraisal. Some programs also require your preliminary ADU plans, which we provide as part of our design-permit-build package. We don’t handle the lending decision ourselves - we connect you with specialists who do - but we make sure your project documentation is organized and accurate so nothing delays your application. Call (951) 577-3472 for a free estimate and we’ll outline exactly what your file would need.
No, estimates are free and come with a written, line-item price under Haven Standard Clause 1. We also offer a Free Second Opinion if you already have a written estimate from another Ontario ADU contractor - bring it in and we’ll review the scope, flag anything that looks incomplete, and give you our assessment at no charge. Call (951) 577-3472 to schedule.
Yes, in most cases. Ontario homeowners sometimes qualify for CalHFA ADU grants, utility rebates, or manufacturer promotions on prefab systems from brands like Abodu, Cover, or Mighty Buildings that we specify and coordinate. These incentives typically reduce your total project cost, which means your financed amount drops accordingly. We structure your written quote to show the pre-incentive price, the incentive credit, and your net amount - so your financing application reflects the real number, not a inflated starting point. Call (951) 577-3472 to see what programs might apply to your specific property and project type.
