Why Build an ADU or Garage Conversion?
Boost Your Home’s Value
Adding an ADU can increase your property’s value by 20 to 35%.
Earn Extra Income
You can rent out a small ADU or converted garage for anywhere from $1,500 to $3,500 a month, depending on where you are and what features you include.
Make Space for What Matters
Whether it’s aging parents, adult kids, or weekend guests, an ADU gives you the flexibility to create a private, comfortable space for the people you care about. You get to design it to fit your lifestyle.
Energy-Efficient and Resource-Saving
ADUs use lower energy and consume fewer resources compared to traditionally sized houses.
A Budget-Friendly Alternative
Building a tiny home ADU is a smart way to save - especially when you compare it to the cost of buying a whole new house or moving. On average, it costs around $180,000 to build an ADU, which is often way more affordable than jumping into today’s housing market.

FAQ
Find Quick Answers About ADUs
What is the average timeline for permitting and building a detached ADU in California?
The timeline typically ranges from 4 to 8 months. Permitting can take anywhere from 1 to 3 months depending on the city, while construction generally takes another 3 to 5 months. At ADUcsale, we manage the entire process for you — from permits to final inspection — to help avoid unnecessary delays.
Do you offer pre-approved ADU plans that meet local zoning and building codes?
Yes, we provide a variety of pre-approved, permit-ready ADU plans that comply with both California building codes and specific local zoning rules. These plans help speed up city approval times and reduce the chances of plan rejections. If needed, we also offer fully customized design services.
Can I finance my ADU project through ADUcsale or do you work with partner lenders?
Yes, we partner with several financing providers who offer ADU-specific loan options such as home equity lines of credit, cash-out refinancing, and renovation loans. We can guide you through the available financing paths and connect you with the right lender for your situation.
Will adding an ADU increase my property taxes or affect my home insurance?
In most cases, adding an ADU will slightly increase your property’s assessed value, which can result in a minor property tax adjustment. However, under California’s Prop 13, your main residence will retain its original assessment. As for insurance, we recommend updating your homeowner’s policy after the ADU is completed to ensure it’s fully covered.
What’s included in your turnkey ADU service — do you handle permits, utilities, and inspections?
Yes, our turnkey service includes everything from site evaluation and architectural planning to permitting, utility hookups, full construction, and final inspections. We manage the entire project on your behalf, so you don’t have to coordinate with multiple contractors or city departments.
