Flexible Financing for ADU in Corona
ADU projects in Corona shouldn’t stall because of cash-flow timing. Call (951) 476-3715 and we’ll walk you through payment options that keep your garage conversion or new detached unit moving forward without the stress of a single large outlay. At Ellery ADU Studio Corona, we’ve financed 900+ projects since 2015, and every one started with a written price before any work began.
Payment Options We Offer
Financing Plans
Third-party financing is available for qualified Corona homeowners, with terms that spread your ADU investment across manageable monthly payments. We work with lending partners who understand construction timelines, so draws align with inspection milestones rather than arbitrary calendar dates. Under Haven Standard Clause 1, your written price is locked before application, so you’re never financing a moving target.
Major Credit Cards
We accept Visa, Mastercard, American Express, and Discover for deposits, progress payments, or full project settlement. Card payments process through our secure system with same-day confirmation, and you’ll receive a documented photo record of work completed before any charge hits your statement.
Cash or Check
Some Corona clients prefer the simplicity of personal check or cashier’s check drawn at project milestones. Others wire funds directly. However you pay, the terms are identical: written scope, fixed price, no change orders without a signed amendment. In the Dos Lagos area, we’ve seen clients combine a cash down payment with financing for the balance to optimize their tax position.
Up-Front Written Pricing
Every Ellery ADU Studio Corona project begins with a line-item quote you can take to your lender, your accountant, or your kitchen table for consideration. No “call for pricing.” No ranges that balloon. The number on the page is the number in the contract, per Haven Standard Clause 1. This matters in Corona’s competitive ADU market, where lenders require documentation before approving construction loans.
Simple Application Process

Step 1: Talk to us about your project. Call (951) 476-3715 or schedule a site visit. We’ll assess your Corona property, identify any setback or utility considerations specific to your neighborhood, and prepare your written estimate.
Step 2: Quick pre-qualify conversation. If financing makes sense for your timeline, we’ll connect you with our lending partners for a soft credit inquiry that won’t affect your score. Most Corona clients receive a decision within one business day.
Step 3: Choose your plan and start. Select the term and payment structure that fits your budget, sign your fixed-price contract, and we pull permits. Your first payment typically aligns with our first site visit, not before.

That depends on the lender’s terms, which vary by program and change with market conditions. We don’t control lender promotions, but we do guarantee your project price won’t change once contracted. If you’re considering a limited-time offer, call us promptly so we can coordinate timing with your financing approval.
