Custom ADU
Can't find a pre-approved plan you like or maybe it doesn't fit your property, or you want to add a garage to it as well? We can get you in touch with a designer and create a custom ADU to fit your needs.
Costs: A custom designed ADU is a longer and more expensive process but you get to create the perfect house for you. On average, the living space is around $250 - $300 a square foot while the garage is $100 a square foot and covered patios are about $40 a sqft.* Prices can vary drastically based on design.
Additional Costs:
Permit process
The permit process varies greatly depending on the area you live in. It could be as quick as two months and as long as a year+ to get a permit. Also, while many of the permit fees are waived, there are still some permit fees, and school fees. These also vary but $8 to $10* a square foot is a rough idea.
Site Development
Each property is unique and will require a site visit from us to address the needs of the house. All houses will need to have a graded and certified house pad. They will also need to have utilities, such as power, sewer, and water to the house. We can typically do this for around $20,000* but the price could vary wildly based on the property.
* Prices listed on this website are for informational purposes only and are not an official price estimate. Coble Homes must visit the site and then will give the customer a formal estimate based on the unique conditions of each property. Coble Homes only takes on as much work as they can handle, and as such may not always be available for hire. Reach out to us for current availability and pricing.
