Frequently Asked Questions
What is an ADU, and why would I need an ADU contractor?
.svg)
An ADU, or Accessory Dwelling Unit, is a secondary housing unit typically located on the same property as a primary residence. You would need an ADU contractor to design and build this additional living space, which can serve various purposes, such as housing family members, generating rental income, or increasing property value.
How much does it cost to build an ADU, and can you provide a rough estimate?
ADU construction costs vary widely based on factors like size, location, materials, and local building codes. On average, you can expect to invest between $100,000 and $300,000 for an ADU. For a more accurate estimate, we offer free consultations and project assessments.
Will your ADU contractor service handle the entire project, from design to construction?
Yes, we offer comprehensive ADU services that encompass design, permitting, construction, and project management. We'll guide you through the entire process, ensuring a seamless experience from concept to completion.
How long does it typically take to build an ADU?
The construction timeline for an ADU varies based on its size and complexity. In general, ADU projects can take anywhere from a few months to a year to complete. Our team will provide a more accurate timeline during the project planning phase.
Do I need to secure permits for an ADU, and will your service assist with the permitting process?
Yes, permits are typically required for ADU construction, and we will assist you in obtaining them. The specific permits needed can vary by location, so our team will ensure that all necessary permits are secured to meet local regulations and building codes. Permit costs are not typically included in the initial project estimate.
