What affects the price
Building an ADU involves variables that shift your total investment. The footprint size and complexity of the architectural design are primary factors. Are you planning a detached unit that requires new utility trenching, or is this a garage conversion that uses existing plumbing? Site accessibility, soil conditions, and your choice of finishes—like luxury flooring versus standard options—also play significant roles. Permitting fees vary widely depending on your local municipality and current zoning requirements. Exact pricing confirmed free on the call.

Frequently asked in Los Angeles
What are the disadvantages of ADUs in Los Angeles?
Potential disadvantages in Los Angeles can include the impact on your existing yard space and increased utility usage. Parking requirements can sometimes be a concern, depending on the specific zone and street. You'll also want to consider the potential for increased noise or privacy issues.

How much does an ADU cost in Los Angeles?
What are the rules for ADUs in Los Angeles?
Los Angeles has relatively favorable ADU regulations, allowing for units up to a certain size without needing to meet typical minimum lot size requirements in many areas. Key rules involve setbacks, off-street parking (though often waived), and ensuring the ADU is a secondary unit to the primary residence. We can help you understand them.
While the initial funding may have been allocated, there could be other state or local programs that offer financial assistance or incentives for ADU construction in California. It's worth checking current availability.
Can I build an ADU above my garage in Los Angeles?
Yes, building an ADU above an existing garage is a very popular option in Los Angeles. This often minimizes the impact on your backyard and can be a more cost-effective approach. You'll need to ensure the garage structure can support the addition and meet all building codes. We can help assess feasibility.
What permits are required for an ADU in LA?
In Los Angeles, you'll need to obtain permits from the Department of Building and Safety. This typically involves submitting plans for review and approval. The process includes building permits, electrical, plumbing, and possibly others depending on your project. Experienced pros can guide you through this system.
