FAQs
Accessory Dwelling Units (ADUs)
1. What is an ADU and why are they popular in California?
An ADU, or Accessory Dwelling Unit, is a secondary home built on the same lot as a primary residence. They’re popular in California because they create extra living space and can be rented out for additional income.
2. What types of ADUs can I build in California?
Options include detached units, attached additions, garage conversions, and basement conversions. The best choice depends on your property, budget, and goals.
3. How much does it cost to build an ADU in Los Angeles?
Most ADUs range from $150,000–$300,000+, depending on design and size. Garage conversions may be less, detached builds usually more.
4. How long does it take to build an ADU?
Typically 8–12 months, including planning, permits, and construction.
5. Can I rent out my ADU in Los Angeles?
Yes, long-term rentals (30+ days) are allowed. Short-term rentals (Airbnb) are often restricted.
6. Do ADUs require parking spaces?
Not always. Many properties near transit don’t require additional parking for ADUs.
7. What’s the difference between an ADU and a Junior ADU (JADU)?
ADUs are full units with kitchens/bathrooms; JADUs are smaller (up to 500 sq ft) and often share facilities with the main home.
8. Do ADUs need to match the style of my home?
Not always, but many cities encourage designs that blend with your primary residence.
9. Can I sell my ADU separately from my house?
Usually no—unless the lot is split under SB-9, an ADU cannot be sold on its own.
10. What’s the resale value of a home with an ADU?
Homes with ADUs often sell for 20–30% more thanks to income potential and flexible use.
SB-9 Projects
11. What are SB-9 projects and how do they work?
SB-9 allows single-family homeowners to split their lot and/or build duplexes, potentially creating up to four homes on one property.
12. How does SB-9 affect single-family homeowners?
It unlocks rental income opportunities and increases property value without having to purchase new land.
13. Do SB-9 lot splits affect property taxes?
Yes, a reassessment may occur, but added equity and rental income usually outweigh higher taxes.
14. Can SB-9 units be combined with ADUs?
Yes, in many cases SB-9 and ADU rules together allow for multiple units on a single lot.
15. How do I know if my property qualifies for SB-9?
Eligibility depends on zoning, setbacks, and lot size. A feasibility study is the first step.
Ground-Up Building
16. What’s the typical timeline for a ground-up build?
Usually 12–18 months, depending on size and complexity.
17. Why build from the ground up instead of remodeling?
Ground-up building gives you full control over layout, modern efficiency, and often higher long-term value.
18. Do I need a general contractor for ground-up construction?
Yes, working with a licensed contractor ensures quality, code compliance, and smooth project management.
Permits & Regulations
19. Do I need a permit to build an ADU or SB-9 project?

Rules vary—some restrict them, while others allow with conditions. Always check local guidelines.
21. Do ADUs or SB-9 projects trigger new building codes?
Yes, all new construction must meet modern California building and energy codes.
Financing & Value
22. Can I finance my ADU or ground-up project?
Yes, with construction loans, home equity loans, or refinancing.
23. How do ADUs help with California’s housing shortage?
They provide affordable housing solutions without requiring new land development.
24. How do I finance a ground-up build?
Most homeowners use construction loans, equity loans, or cash-out refinancing.

Yes, many homeowners use ADUs for multigenerational living, providing privacy and independence while keeping loved ones close.

Absolutely. Many California homeowners move into a newly built ADU and rent the larger primary home, creating more income while simplifying their own lifestyle.
28. Are ADUs good for home offices or creative studios?
Yes. ADUs aren’t just for living space—they can also serve as dedicated home offices, art studios, or retreats, giving you privacy and productivity without distractions.
29. Can a ground-up build support multi-generational living?
Definitely. With ground-up construction, you can design a home that includes separate living spaces, dual kitchens, or private entrances, making it perfect for large families living together.
30. Are ADUs a good option for retirement planning?
Yes. An ADU can provide steady rental income during retirement, house a caregiver when needed, or allow you to age in place while still maintaining independence.
31. Can I use an SB-9 lot split to create a home for my children?
Yes. Many homeowners split their lot to build a second home for children or family members, giving them independence without leaving the neighborhood.
