FAQ
Frequently Asked Questions
An Alternative Dwelling Unit, Accessory Dwelling Unit, or ADU, is a self-contained living unit that is secondary to the main house on a residential property. The key difference between an ADU and a traditional home addition is that ADUs are separate living units with their own entrance, kitchen, bathroom, and utilities.
Yes, obtaining a permit is necessary for building a custom ADU. As experienced contractors, we have a thorough understanding of the local regulations and building codes. We can guide you through the permit application process, ensuring that all necessary documentation and requirements are met to obtain the required permits.
The cost to build an ADU can vary based on several factors, such as the size, design, materials used, and site-specific considerations. While each project is unique, building an ADU is generally a cost-effective way to add living space to your property compared to traditional home additions. Our team of experts at Engco will work closely with you to understand your goals and budget, providing you with a detailed cost estimate tailored to your specific project. Our architects strive to deliver exceptional value by optimizing the design and construction process to ensure your ADU is built within your budget.
