Question 1

How much does an ADU cost in Home Gardens and the surrounding area?

Accepted Answer

ADU costs in the Inland Empire vary based on size, site conditions, and whether you're converting existing space or building new. A garage conversion typically runs less than a detached unit, but a detached ADU gives you more design freedom and often appraises higher. The best way to get a real number is a free on-site estimate, where we measure your lot, check access, and prepare a written line-item quote. Call (855) 594-0655 to schedule yours.

Question 2

How long does an ADU project take from start to finish?

Accepted Answer

Expect the full process, from design and permitting through construction and final inspection, to take several months. The design and permit phase varies by jurisdiction; cities like Corona and Redlands have different review timelines than unincorporated county areas like Valle Vista or Mentone. We give you a realistic schedule once we know your property and your local building department's current backlog. Call (855) 594-0655 and we'll walk you through what applies to your address.

Question 3

Will the price change once construction starts?

Accepted Answer

We build our estimates with fixed pricing and written line items, so you know what you're paying before you sign. If you change the scope, such as upgrading finishes or adding square footage, we document the change order and the cost adjustment in writing before work continues. We don't surprise you with a bigger bill at the end. Call (855) 594-0655 for a free estimate and we'll show you exactly how we price a project.

Question 4

Do you pull the permits for an ADU?

Accepted Answer

Yes. Sapphire ADU Builders handles the full permit package, submittal, plan check responses, and inspections for your project. We know the specific requirements in each city we serve, from Historic and Scenic Preservation review in Redlands to county Environmental Health coordination for septic systems in Valle Vista. You don't chase the building department; we do. Call (855) 594-0655 to get started.
