Accessory Dwelling Units (ADUs) are one of the hottest trends in Los Angeles real estate. Whether you’re looking to house family members, earn passive income, or increase your property value, building an ADU is a smart move. But before you start sketching plans, there are some essential things you need to know.
At Level Up Contractor, we help LA homeowners navigate the complexities of building ADUs—from concept to completion. Here’s everything you should consider before starting your ADU project in Los Angeles.
1. Know the Types of ADUs
There are three main types of ADUs:
- Detached ADU: A standalone structure, often converted from a garage or built from the ground up in the backyard.
- Attached ADU: Built as an addition to the main house.
- Interior ADU (Junior ADU or JADU): Created within the existing structure, like a converted basement or portion of your home. Each type has its own pros, cons, and regulations.
2. Zoning Laws and Lot Size Matter
Before anything else, you need to confirm that your lot is zoned for an ADU. Los Angeles has become more ADU-friendly in recent years, but specific rules still apply based on:
- Lot size and zoning
- Setbacks (distance from property lines)
- Maximum square footage
- Parking requirements (some waived depending on location) Our team ensures your plans comply with city and state guidelines before breaking ground.
3. Permits and Approvals Are Mandatory
You cannot build an ADU in LA without city permits. The process can be lengthy and involves:
- Architectural plans
- Title 24 energy compliance
- Structural and zoning reviews
- Inspections We streamline the entire permitting process so you stay compliant and stress-free.
4. Design for Comfort and Function
An ADU isn’t just a box in the backyard—it should be a livable, functional space. We help clients design ADUs that include:
- Open floor plans
- Full kitchens and bathrooms
- Private entrances
- Plenty of natural light
- Energy-efficient materials and appliances
5. Budget Wisely
On average, building an ADU in LA can cost between $90,000 and $300,000 depending on the size, features, and site conditions. Be sure to account for:
- Design and architectural fees
- Permits and city fees
- Construction and materials
- Utility upgrades or new connections We offer detailed quotes and timelines so there are no surprises.
6. Choose the Right Builder
Your contractor should be experienced, licensed, and familiar with LA’s ADU regulations. At Level Up Contractor, we’ve built dozens of ADUs across Los Angeles with satisfied homeowners who now enjoy rental income, guest houses, and more.
7. Consider Your Long-Term Plans
Ask yourself:
- Will I rent this ADU or use it for my family?
- Do I want to age in place and use it as a future downsized home?
- Will this help increase my resale value? Thinking ahead ensures you build a space that continues to benefit you over time.
8. Financing Your ADU
There are several ways to fund your ADU project:
- Cash or savings
- Home equity loans or lines of credit (HELOC)
- Construction loans
- State or local grant programs (especially for affordable housing) We can connect you with trusted financing partners to help you find the right option.
