ADU FAQ: What Homeowners Want to Know
Thinking about building an Accessory Dwelling Unit (ADU)? Here are the most common questions we hear—from zoning rules to energy efficiency.
1. What is an ADU, and is it legal in my area?
An ADU is a secondary housing unit on your property—like a backyard cottage, garage conversion, or in-law suite. Zoning laws vary by city, so check with your local planning department or let us help you navigate the rules.
2. How much does it cost to build an ADU?
Costs can range from $100K to $400K+ depending on size, design, finishes, and whether you’re building from scratch or converting existing space. We can help you budget smart—especially with energy-efficient options that pay off long-term.
3. How long does it take to build an ADU?
From planning to completion, expect 6–12 months. This includes design, permitting, and construction. We’ll guide you every step of the way to keep things moving efficiently.
4. Do I need a permit to build an ADU?
Yes—permits are required for almost all ADUs. We handle the paperwork, code compliance, and inspections so you don’t have to.
5. Can I rent out my ADU legally?
Many areas allow long-term rentals, and some permit short-term rentals (like Airbnb). We’ll help you understand what’s allowed in your city and make sure your ADU is rental-ready.
6. How big can my ADU be?
Size limits depend on your lot, zoning, and the type of ADU. In many areas, detached ADUs can be up to 800–1,200 sq. ft. We’ll help you maximize space within legal limits.
7. Will an ADU increase my property value?
In most cases—yes. An ADU adds livable square footage and income potential, which can significantly raise your home’s value and market appeal.
8. How energy-efficient can I make my ADU?
Very! From solar panels and mini-split HVAC systems to smart insulation and low-flow fixtures, we specialize in building ADUs that are stylish and sustainable.
9. Where on my property can I build an ADU?
Location depends on setbacks, access requirements, and utility placement. Detached units typically go in backyards, while attached ones can extend your home or convert a garage.
10. Can I convert my garage into an ADU?
Absolutely. Garage conversions are a popular, cost-effective way to add an ADU—especially when you incorporate energy upgrades during the transformation.
