FAQ - ADU Builder in Sacramento

Your ADU Questions, Answered Clearly

From permitting to interior finishes, explore straightforward answers that help you understand the ADU process and make informed decisions every step of the way.

ADU PROCESS

How long does IMKAT take to build an ADU?

Most ADUs take 4–6 months to build after permits are approved. Timelines vary based on city processes, scope, and customization.

Do you handle permits and engineering?

Yes. We manage design, engineering, and all permit approvals in-house. Our team prepares the plans, submits them to the city, handles revisions, and ensures everything is approved before construction begins.

Can you help me understand what size ADU I can build?

Yes. We review your lot size, zoning rules, and city requirements to determine the maximum ADU size allowed and guide you through the design and planning process.

Do I need to be present during construction?

No. We handle the full construction process and keep you updated throughout the project, so you don’t need to be on site.

COSTS & FINANCING

How much does an ADU typically cost?

Costs depend on size, finishes, and site conditions. We provide a clear, upfront estimate after reviewing your property and design preferences.

Do you offer financing?

Yes. We can connect you with financing partners who offer loan options for ADU and construction projects, depending on your eligibility.

Does choosing a finish package affect cost?

Yes. Different finish packages include different materials and upgrades, which can change the total project cost. We provide clear pricing so you can choose what fits your budget.

Are there hidden fees?

No. We provide clear, upfront pricing with no hidden fees. Any changes to the project are discussed and approved before additional costs are added.

DESIGN & FINISHES

Can I customize the interior design?

Yes. You can stay with a curated package or mix and match materials. Full custom design is also available.

Do finishes impact permitting?

Usually no. Permits are based on the design and structure, not the finish materials, but major changes to the plans may require revisions and city approval.

Can I change my selections after choosing a package?

Yes. Changes can be made after selecting a package, but they may affect cost or timeline. We always review and approve any updates with you first.

Do you offer 3D renderings or design previews?

Yes. We provide design previews and layout drawings, and in many cases 3D renderings, so you can see how your project will look before construction starts.

PROPERTY REQUIREMENTS

How do I know if my property qualifies for an ADU?

Most California lots do. We confirm zoning, setbacks, utility access, and available space during your consultation.

Do I need additional parking for an ADU?

It depends on local city rules. In many cases parking is not required, but we verify the requirements based on your property and zoning before starting the project.

Can an ADU replace my garage?

Yes. A garage can often be converted or replaced with an ADU, depending on local city rules. We check the zoning and permit requirements before starting the design.

Can I rent out my ADU?

Yes. ADUs can usually be rented out, but rental rules depend on local regulations. We help you understand what is allowed in your area.

CONSTRUCTION & WARRANTY

What’s included in your construction service?

Everything—from foundation, framing, roofing, plumbing, electrical, HVAC, insulation, drywall, finishes, and final inspection.

Do you provide a warranty?

Yes. We provide a construction warranty and review the coverage with you before the project begins.

How do inspections work?

Inspections are done at different stages of construction. We schedule them, meet with the city inspector, and make sure everything passes before continuing the work.

What if something changes during construction?

If changes come up, we review them with you first. We explain any cost or timeline impact and move forward only after your approval.
