What affects the price

Whether you’re building a detached unit or converting an existing garage shifts the permit requirements and structural work needed. We provide exact pricing confirmed free on the call.

Frequently asked in Los Angeles
What's involved in building an ADU in Los Angeles?
What are the rules for renting out an ADU in Los Angeles?
In Los Angeles, there are specific rules for renting out an accessory dwelling unit. Generally, the ADU can be rented out separately from the primary residence. However, you must comply with landlord-tenant laws regarding leases, rent control, and habitability standards. The city also has regulations on short-term rentals, so check those if that's your plan.
Are modular ADUs a good option for Los Angeles properties?
Modular ADUs can be a great option for Los Angeles properties. They are built off-site in a factory and then transported and assembled on your lot. This often leads to faster construction times compared to traditional builds. Modular units can also be more cost-effective. They still need to meet all local building codes and permit requirements.
What's the general process for ADU building in Los Angeles?
Are there any grants available for ADUs in Los Angeles?
While specific grant programs can change, it's worth investigating potential ADU grants in Los Angeles. Some cities or state programs occasionally offer incentives for ADU development, particularly for affordable housing. Inquire with local housing authorities or check the city's planning department website for current opportunities. The pros can advise if any applicable programs exist.
What makes a detached ADU different in Los Angeles?
A detached ADU in Los Angeles is a separate dwelling unit located on the same lot as your main house but not attached to it. This means it has its own entrance and utilities. These are often built in backyards or on side yards. The city has specific rules regarding setbacks and lot coverage for detached ADUs.
How do I get a permit for an ADU in Los Angeles?
