Building an accessory dwelling unit (ADU) is a great way to add value and flexibility to your property, but it’s also a major project that requires careful planning. Whether you’re creating a home for a family member, generating rental income or simply expanding your living area, here are three important things to think about before you begin: 1. Know what you want to spend. ADU costs can range widely depending on your design and material choices. Before starting, make sure you have a clear understanding of your budget and how it relates to your expectations. Everything from bathroom tile and kitchen cabinets to appliances and plumbing fixtures can significantly affect your bottom line. Decide early whether you’re aiming for something basic or a high-end build so you can plan accordingly and avoid cost surprises mid-project. 2. Choose the right professional for the job. Your contractor will make or break your ADU project, so it’s important to hire someone who can guide you through the process from start to finish. Look for a company that’s equipped to help with the design, permitting and selection of finish materials. Also, make sure they have the employees, credentials and communication style that match the demands of your project. 3. Think about the calendar. Timing is everything when it comes to construction. Seasonal weather conditions can slow progress, so plan your start date around the climate in your area. You should also consider your ultimate goal—are you building the ADU for a family member or do you have a tenant lined up? Knowing your ideal move-in date will help you and your contractor set realistic deadlines and minimize disruptions.
