Modular homes have become a popular housing solution for many California homeowners, especially those seeking additional living space, rental units, or in-law suites. But one of the most common questions people have is whether these homes are delivered in a turn-key condition meaning you can move in the same day they arrive.
The answer depends on the builder, the construction process, and the level of service offered. For companies like Nestadu, the goal is to make sure your accessory dwelling unit (ADU) is ready for immediate use, from the flooring and finishes to the appliances and final touches.
Modular Homes
A modular home is built in sections or “modules” at a controlled off-site facility. These sections are then transported to the homeowner’s property and assembled on a prepared foundation.
Unlike mobile homes, modular homes are designed to meet the same building codes as traditional site-built homes. They often feature high-quality materials, modern layouts, and a faster construction timeline.
Many homeowners choose modular homes because:
- They save time: Construction in a factory setting avoids weather delays.
- They can be cost-effective: Building off-site can reduce labor and waste.
- They offer flexibility: Custom layouts, finishes, and features are available.
What Does “Turn-Key” Mean in Housing?
The term “turn-key” comes from the idea that all you need to do is turn the key in the door and start living in your new home. In housing, this means the property is fully completed, inspected, and ready for immediate occupancy.
A true turn-key home typically includes:
- Fully installed electrical and plumbing systems.
- Finished flooring, paint, and trim work.
- Kitchen appliances and bathroom fixtures in place.
- Utility connections complete.
- Sometimes, landscaping and exterior features included.
This is different from a semi-finished home, where some work like painting, flooring, or utility hookups might still be required after delivery.
Are Modular Homes Delivered as Turn-Key Houses?
The answer varies from builder to builder. Some modular homes arrive with only the structure completed, requiring the homeowner to arrange for finishing work like plumbing hookups, appliance installation, and landscaping. Others like Nestadu’s ADUs are designed to be delivered in a fully move-in-ready state.
The determining factors include:
- The builder’s scope of work: Not all modular home companies provide complete site preparation and finishing.
- Permit and code requirements: Local regulations may require certain on-site work to be completed separately.
- Customization choices: High-end finishes, special appliances, or unique layouts may add steps before the home is fully ready.
The Nestadu Approach to Turn-Key ADUs
At Nestadu, the aim is to simplify the entire process so you don’t have to manage multiple contractors or stress over missing details.
Here’s what a typical Nestadu turn-key ADU delivery includes:
- Site preparation Grading, foundation work, and utility connections are handled before the modular unit arrives.
- Factory-built quality The structure, walls, roof, windows, and doors are all built to California building standards.
- Interior completion Flooring, paint, trim, kitchen cabinets, countertops, and bathroom fixtures are all installed in the factory.
- Appliances installed Standard appliances, such as stoves, refrigerators, and dishwashers, are included.
- Exterior finishing Exterior siding, paint, and design details match the existing home’s style.
Nestadu also ensures that all necessary inspections are passed, permits are finalized, and the home meets or exceeds California code requirements.
Benefits of Choosing a Turn-Key Modular Home
A turn-key modular home offers peace of mind and practical advantages:
- Convenience – No need to coordinate multiple contractors or oversee construction details.
- Predictable Costs – A clear, upfront price avoids the financial uncertainty of on-site changes.
- Time Efficiency – Faster occupancy since all major work is completed before delivery.
- Consistent Quality – One team manages every aspect of the build, ensuring uniform standards.
For many homeowners, especially those adding an ADU for family or rental purposes, the ability to move in or start renting right away can make a big difference in both comfort and return on investment.
Things to Keep in Mind Before Buying
While turn-key modular homes offer many benefits, there are still a few points to consider:
- Site-Specific Challenges – Sloped lots, difficult soil conditions, or tight spaces may require extra preparation time.
- Permit Timelines – Even with a completed home, you can’t move in until inspections are complete.
- Optional Upgrades – Choosing premium finishes or appliances may extend your project timeline.
Understanding these factors ahead of time helps set realistic expectations and ensures a smoother building process.
