Alright, let us talk about ADUs in Beaverton. You might have an idea for an Accessory Dwelling Unit. You might even have a dream of that extra space. This could be a rental unit. It could also be a home for family. Sometimes, it is just a quiet retreat. Before you get too far down the road, you need to get real about your property. We call this a site assessment. This is where the rubber meets the road for your ADU project in Beaverton. If you skip this step, or do it wrong, you are looking at headaches. You are also looking at delays. In addition, you are looking at a lighter wallet. We have seen this happen with many ADU projects.
Here at Coastal ADU, we know Beaverton properties inside and out. We understand the older, established neighborhoods with mature trees. We also understand the newer developments. Every lot has its quirks. These quirks can make or break your Beaverton ADU project. So, let us break down what you need to know before your ADU site assessment. We will also cover what to know during and after your ADU site assessment.
Before You Dig: The Initial Reconnaissance (DIY First)
Before you even think about calling an ADU contractor for your Beaverton ADU project, there is a lot you can do yourself. This is not about becoming an expert. This is about getting smart. This way, you can ask the right questions. You will also understand the answers better for your Beaverton ADU.
- Know Your Zoning & Setbacks for your Beaverton ADU: This is step one. It is always step one for any ADU project in Beaverton. Beaverton allows ADUs on most residential lots. For a detached ADU, you are generally looking at a maximum of 800 square feet. This can also be 50% of your primary dwelling's gross floor area. You will use whichever is less. Setbacks are the minimum distance your new structure needs to be from your property lines. In many Beaverton residential zones, detached ADUs can be as close as 5 feet from side property lines. They can also be 5 feet from rear property lines. This is true if the building height is limited to 15 feet. Front yard setbacks usually match your main house. You can find this information on the City of Beaverton's Planning Department website. It is not always the easiest to navigate. However, it is important for your Beaverton ADU project.
- Eyeball Your Utilities for your Beaverton ADU: You need to know where your water lines are. You also need to know where your sewer lines are. In addition, you need to know where your electrical lines are. Are they overhead or underground? Where do they connect to your main house? Where do they enter your property? You are not going to be designing the hookups. However, knowing the general layout gives you a huge advantage. If you are building a detached ADU in Beaverton, you will likely need new lines run from your main house. You might also need them run directly to the street.
- Look at Your Lot: Slope and Drainage for your Beaverton ADU: Beaverton has its share of clay-heavy soils. This is especially true in areas that used to be farmland. This means water does not always drain well. Walk your property after a good rain. Where does the water pool? Are there any obvious low spots? Are there areas that stay soggy? This is a big one. Proper drainage is important for your ADU's foundation. It is also important for its longevity. You do not want water constantly sitting around your new ADU structure.
- Trees, Glorious Trees for your Beaverton ADU: We love our trees in Beaverton. However, sometimes they are right where you want to build your ADU. Check if any trees in your proposed ADU footprint are significant in size. This means over 10 inches in diameter at 4.5 feet above ground. You also need to check if they are street trees. Removing these often requires a permit. Sometimes it also requires replanting or mitigation fees. Do not just chop them down. The city takes this seriously for any Beaverton ADU.

- Geotechnical Soil Analysis for your Beaverton ADU: Remember those clay soils? A geotechnical engineer will analyze your soil composition. This is not just about drainage. It is about what kind of foundation your ADU needs. Soft soil or deleterious material needs to be removed. It also needs to be replaced with structural fill. This report is vital for structural engineering. It can also prevent costly foundation issues down the road for your Beaverton ADU.
