Whether you're looking to add rental income, house a family member, or increase your property's value, an Accessory Dwelling Unit (ADU) is one of the smartest investments a Long Beach homeowner can make.

 

At Sennikoff Architects, we specialize in designing ADUs that are thoughtfully tailored to your property, your lifestyle, and your goals — from the first sketch to the final permit approval.

 

What Is an ADU?

 

An ADU is a self-contained residential unit built on the same lot as an existing single-family home.

 

In California, recent state legislation has made it easier than ever for homeowners to build ADUs, and Long Beach has embraced these changes with streamlined permitting that makes the process more accessible.

​

ADUs can take several forms depending on your property:

 

  • Detached ADUs — A fully separate structure built in your backyard

  • Attached ADUs — An addition connected to your primary home

  • Garage Conversions — An existing attached or detached garage converted into a living space

  • Junior ADUs (JADUs) — A smaller unit created within the existing footprint of your home

Why Work With an Architect for Your Long Beach ADU?

​

Many homeowners assume an ADU is a simple construction project that doesn't require an architect. In reality, the design and permitting process involves navigating Long Beach's zoning codes, setback requirements, height restrictions, and utility connection rules. These are details that can derail a project or add unexpected costs without experienced guidance.

​

As a California licensed architect with nearly 35 years of experience, we bring award-winning design sensibility and deep local knowledge to every project. We don't offer cookie-cutter ADU plans. Every unit we design is custom and conceived to complement your existing home architecturally while maximizing livable space and long-term value.

We have designed and permitted ADUs throughout Long Beach and the greater Southern California area, including detached backyard units, garage conversions, and above-garage living spaces. Our completed projects span a range of styles and budgets, each one designed to feel like a natural extension of the property rather than an afterthought.
