MiniPlans FAQ
Is building an ADU still worth it?
Absolutely. ADUs are one of the smartest investments a homeowner can make right now. With housing demand at an all-time high, a finished ADU can generate $1,500–$3,500/month in rental income depending on your area, often paying for itself within 5–7 years. Beyond income, ADUs consistently increase property values by 20–30%. Whether you're housing family, generating passive income, or future-proofing your property — the ROI speaks for itself.
How long does it take to build an ADU
Most ADUs take 6–12 months from permit approval to move-in ready. Our job is to make sure your design and plans are permit-ready as fast as possible, so your contractor can break ground without delays. The faster your plans are approved, the sooner your ADU starts generating value.
How much does an ADU cost to build?
ADU costs typically range from $150,000–$350,000 depending on size, finishes, and site conditions. As your ADU designer, we provide detailed, accurate plans that help contractors give you precise bids, eliminating costly surprises down the line. Good design upfront saves you significantly on construction costs.
Do I need special permits to build an ADU?
Yes, but don't let that stop you. Every ADU requires local permits, but California has made the process significantly easier in recent years with pro-ADU legislation. We design your plans specifically to meet local code requirements, making the permitting process as smooth as possible for you and your contractor.
What's the difference between an attached and detached ADU?
An attached ADU shares a wall with your main home, while a detached ADU is a separate standalone structure in your yard. Detached ADUs offer more privacy and typically rent for more, while attached ADUs are usually less expensive to build. We'll help you figure out which option makes the most sense for your property and design goals, then create plans that bring that vision to life.
