Five Ways Engineers Ensure That ADUs Are Properly Constructed

An architectural engineer is a professional who plans, designs, and oversees the construction of buildings. They work with architects to create blueprints and ensure that the building is structurally sound. With the growing trend of adding accessory dwelling units (ADUs) to properties in California, engineers play an essential role in successfully completing many new constructions. Here are five ways that engineers ensure that ADUs) are properly constructed:

1. Keeping it up to code

Depending on the location of the ADU, it may be necessary to obtain a permit from the city or county. The engineer will work with the architect and contractor to ensure that all paperwork is correctly filled out and submitted. In addition, they will also need to provide the city with a copy of the blueprints and construction plans. In some cases, the engineer may also be required to attend meetings with the city planning commission.

According to Pedram Zohrevand, President of CES4 and Director of Engineering, engineers also make sure the spacing between the ADU and the house or main building meets fire code requirements. Some of the guidelines engineers need to consider when constructing an ADU include ensuring the ADU is the correct size, has the required number of exits, and meets all fire safety standards. In addition, engineers also verify that the construction materials meet code requirements.

2. Managing the utilities

Another important aspect that engineers oversee is the connection of utilities to the ADU. This includes water, gas, and electricity. They work with the utility companies to confirm the ADU is properly connected and that all safety standards are met. In addition, they may also need to install new utility lines to accommodate the ADU. Depending on the area’s zoning guidelines, the engineer will assist with deciding if new utility meters are necessary for the ADU.

3. Ensuring structural soundness

Perhaps the most integral role engineers play in the construction of ADUs is ensuring that the structure is sound. An engineer is looking for a strong foundation that will support the weight of the ADU and any additional loads that may be placed on it (such as snow load in colder climates). They will also verify that the foundation is appropriately constructed and meets all code requirements.

When framing an ADU, engineers look for lumber of the correct grade and thickness. In addition, they verify that the lumber is cut correctly and drilled. The engineer will also check that all nails and screws are used correctly and that there is sufficient overlap of roofing material.

4. Conducting inspections

During the construction of the ADU, engineers stay up-to-date on the progress by conducting regular inspections. Pedram Zohrevand believes this is crucial as it allows the engineers to catch any potential problems early on and avoid delays in the construction process.

An engineer inspecting an ADU’s construction may find various problems, such as incorrect framing, improper installation of utilities, and substandard construction materials. If these problems are not corrected, they could lead to structural failure or other safety hazards.

5. Providing a Certificate of Occupancy

Once the ADU is completed, the engineer will provide a certificate of occupancy. This document states that a building or structure meets all applicable building codes and is safe for occupancy. If you do not have a certificate of occupancy, you may not be able to live in or rent out your ADU legally.

Final Thoughts

Engineers play a vital role in the construction of accessory dwelling units. Following building code requirements, managing utilities, and ensuring structural soundness help create safe and habitable spaces for residents. In addition, their inspections and occupancy certificates help ensure that ADUs are up to code and meet all safety standards.
