Question 1

What is an ADU?

Accepted Answer

ADU stands for Accessory Dwelling Unit — basically, a small second home built on the same lot as your main house. People also call them granny flats, casitas, in-law units, or backyard cottages. They have their own kitchen, bathroom, and entrance, so they work as a rental, a guest house, an office, or a place for family.

Question 2

Can I build one on my property?

Accepted Answer

California law says nearly every single-family homeowner can build at least one ADU. Your city will have rules about how big it can be, how far it must sit from property lines, and how tall it can go. Take the 2-minute check above — we'll tell you what's actually possible on your lot.

Question 3

How much does it cost?

Accepted Answer

Most backyard homes in Northern California cost between $200,000 and $450,000, depending on size and finishes. A small studio is on the lower end; a 2–3 bedroom unit is on the higher end. We give you a real, written price for your specific property within 24 hours of a free site visit.

Question 4

How long does the process take?

Accepted Answer

Plan on 12 to 18 months from start to finish. Design and blueprints take 3–6 months, city permits take 3–6 months, and construction takes 6–12 months. We handle the permits and paperwork for you, so you're not stuck navigating city hall alone.

Question 5

Will an ADU raise my property taxes?

Accepted Answer

Yes, but only the new ADU gets reassessed — not your entire property. Your main house keeps its existing tax base. The added value is usually modest compared to the rental income or resale bump you gain.

Question 6

Do I need extra parking?

Accepted Answer

Usually not. California law protects homeowners from being forced to add extra parking for an ADU if you're within half a mile of public transit, or if your unit is under 750 square feet. Most properties in the Sacramento and Bay Area qualify.

Question 7

Can I rent it out?

Accepted Answer

Yes — California allows you to rent your ADU. Many homeowners earn $1,500–$3,500 per month in the Sacramento and Bay Area. Long-term rentals are allowed almost everywhere; short-term rentals like Airbnb depend on your city's rules.

Question 8

What if I don't have plans yet?

Accepted Answer

No problem at all. Most people start without blueprints. We have ready-made ADU layouts starting at $1,999, and we can connect you with an architect if you want something custom. We'll walk you through it step by step.
