🏗️ YOUR COMPLETE GUIDE TO BUILDING AN ADU IN CALIFORNIA
Adding an Accessory Dwelling Unit to your property is one of the smartest investments you can make as a California homeowner. Whether you want rental income, a space for aging parents, a home office, or simply to increase your property value, an ADU checks all the boxes. But the process can feel overwhelming if you don't know where to start. Team Remo has put together this step-by-step guide to help Southern California homeowners navigate the ADU building process from start to finish! 📋
📐 STEP 1: PLANNING AND DESIGN
Before you break ground, you need a solid plan. Start by determining what type of ADU makes sense for your property: detached (standalone building), attached (addition to your home), or conversion (garage or existing space). Check your city's specific ADU regulations — while California state law has made ADUs easier to build, each city in Southern California (Whittier, La Mirada, Downey, etc.) may have additional requirements for setbacks, height, and size. Hire an architect or designer experienced with ADUs to create plans that maximize your space while meeting all code requirements. Most ADUs range from 400-1,200 square feet. 📏
📋 STEP 2: PERMITS AND APPROVALS
Thanks to California's streamlined ADU laws, the permit process is faster than ever — but it still requires patience. Submit your plans to your local building department for review. Most cities must process ADU permits within 60 days. You'll need building permits, and potentially electrical, plumbing, and mechanical permits. The good news: California law prohibits cities from requiring owner-occupancy for ADUs, charging excessive fees, or imposing unreasonable parking requirements. Budget $5,000-$15,000 for permits and fees depending on your city. Your contractor or architect can often handle the permit process for you! 📄
💰 STEP 3: BUDGETING AND CONSTRUCTION
ADU construction costs in Southern California typically range from $150,000-$350,000+ for a new detached unit, depending on size and finishes. Garage conversions are usually cheaper at $80,000-$150,000. Construction typically takes 4-8 months once permits are approved. Choose a licensed, insured contractor with ADU experience — this is not a DIY project. Get at least 3 bids, check references, and verify their license with the California Contractors State License Board. Always have a written contract with a detailed scope of work, timeline, and payment schedule. Budget 15-20% extra for contingencies! 💵
🔑 STEP 4: FINISHING AND RENTING
Once construction is complete, you'll need a final inspection to get your certificate of occupancy. Then it's time to prepare your ADU for tenants — or whatever use you've planned. If renting, research comparable rental rates in your area. A well-built ADU in Southern California can command $1,500-$3,500+ per month depending on location and size. Screen tenants carefully, set up a lease agreement, and consider hiring a property manager if you don't want to handle tenant relations yourself. Your ADU investment should start paying for itself immediately! 🏆
