Custom ADU Design in Los Angeles

An ADU design-build firm manages every stage of your project under one roof — from initial concept and architectural design to permitting and construction. This approach ensures seamless communication, accurate pricing, and faster timelines. Instead of hiring separate designers and contractors, you’ll work with one team who’s accountable for the entire build.

Costs can vary depending on your property, city requirements, and design preferences, but most ADUs in Los Angeles range from $250 to $500 per square foot. A discovery call helps narrow that down quickly, giving you real numbers upfront. Go ADU provides guaranteed pricing before construction begins, so there are no surprises later.

The typical ADU design-build process takes between six to nine months from consultation to completion. Design and permitting often take 8–12 weeks, while construction usually takes 4–6 months depending on scope. Our streamlined approach eliminates delays caused by coordinating multiple vendors, helping you move in or rent out faster.

Working with a single design-build contractor eliminates the finger-pointing that happens when architects and builders disagree. You’ll have one point of contact, one contract, and one clear timeline. This reduces errors, improves accountability, and keeps the budget consistent from start to finish.

Yes, Go ADU handles the entire permitting process from start to finish. Our team prepares your architectural plans, submits them to the city, and manages all plan checks and revisions until your project is fully approved. We’re familiar with Los Angeles’ complex zoning laws and ADU regulations, so you don’t have to worry about red tape.

Absolutely! Every ADU we build is custom-designed to fit your property layout, lifestyle, and budget. Whether you want a detached backyard unit, a garage conversion, or a multi-story ADU, our architects collaborate with you on 3D models and finish selections to bring your vision to life.

We’re not just contractors — we’re homeowners too, so we understand how stressful this process can feel. Go ADU is built on three values: transparency, guaranteed pricing, and accountability. We never take large upfront deposits, and we don’t get paid until milestones are complete. That’s why our clients call us “the contractors who actually show up.”

Yes! Garage conversions are one of our specialties. We’ll assess your existing structure to determine what’s possible, create detailed plans that meet local code, and transform it into a livable, fully finished ADU. It’s a fast, affordable way to add square footage or create a rental unit without building from scratch.

Definitely. We design for energy efficiency and sustainability on every project. That includes solar-ready roofs, energy-saving insulation, LED lighting, low-flow fixtures, and durable low-VOC materials. These upgrades not only lower your utility costs but also make your home healthier and more comfortable for years to come.

Yes, in most cases, adding an Accessory Dwelling Unit significantly boosts property value. A well-designed ADU provides flexible living space and the potential for rental income, both of which appeal to future buyers. Many of our clients see a value increase of over 30% after completing their ADU project.
