Our ADU Construction Process
We handle everything from concept to completion, managing the complex process so you don't have to navigate permits, subcontractors, and inspections alone.
1
Site Evaluation & Design Consultation
Elias personally meets at your Long Beach property to assess your lot, discuss your goals (rental income, family housing, home office), and review initial design concepts. We evaluate setbacks, utilities, access, and any site-specific challenges before moving forward.
2
Design & Engineering
We work with architects and structural engineers familiar with Long Beach building codes to create ADU plans optimized for your lot. Whether you want a modern minimalist studio or a traditional cottage-style two-bedroom, we design for both aesthetics and function.
3
Permitting & Approvals
Our team submits all applications to the Long Beach Planning Department and Building & Safety Division. We handle plan checks, address any city comments, and coordinate inspections. California's ADU laws mandate 60-day approval timelines for compliant plans.
4
Site Preparation & Foundation
Once permits are approved, we begin excavation, grading, and foundation work. Southern California's varied soil conditions require proper engineering—we test soil, install proper drainage, and pour foundations built to last.
5
Framing, Utilities & Systems
We frame your ADU structure, install electrical and plumbing systems, run HVAC, and coordinate with utility companies for separate meters if required. All work meets California Title 24 energy efficiency standards.
6
Interior & Exterior Finishes
From drywall and flooring to kitchen cabinets and bathroom tiles, we complete all finish work to your specifications. We use quality materials and experienced tradespeople to ensure your ADU looks and feels like a standalone home.
7
Final Inspections & Certificate of Occupancy
We coordinate all required inspections (framing, electrical, plumbing, final) with Long Beach Building & Safety. Once approved, we obtain your Certificate of Occupancy and hand you the keys to your completed ADU.
Types of ADUs We Build
Detached ADUs
Standalone structures built in your backyard offer maximum privacy and rental income potential. Ideal for long-term rentals, Airbnb income, or guest houses. We commonly build 600-850 square foot detached ADUs with full kitchens, bathrooms, and separate utility meters.
Best For: Rental income, maximum privacy, property value
Attached ADUs
Connected to your main house through a shared wall or breezeway, attached ADUs cost less than detached units while still providing separate living quarters. Perfect for aging parents or adult children who want independence while staying close to family.
Best For: Multigenerational living, shared utility savings
Garage Conversions
Transform your existing garage into a livable ADU, the fastest and most affordable ADU option. We maintain structural integrity while adding insulation, utilities, and finishes to convert your garage into a comfortable living space.
Best For: Fastest ROI, existing structure, budget-conscious
Junior ADUs (Internal Conversions)
Convert interior space within your existing home (spare bedroom, bonus room) into a small independent unit with separate entrance and kitchenette. Limited to 500 square feet under California law.
Best For: Smallest footprint, interior conversion, lowest cost

Frequently Asked Questions
An ADU (Accessory Dwelling Unit) is a secondary housing unit on a residential property. ADUs are an excellent way to add rental income, house family members, or increase your property value. California has made ADU construction easier with streamlined permitting, and Long Beach is particularly ADU-friendly.
Typically, ADU construction takes 4-8 months from permit approval to completion. The permitting process can add 2-4 months depending on your jurisdiction. We handle all permit coordination to streamline the timeline as much as possible.
In Long Beach, detached ADUs can be up to 1,200 square feet. Attached ADUs are limited to 50% of the primary dwelling's floor area. Junior ADUs (JADUs) are limited to 500 square feet. We'll help you understand what's possible on your specific lot.
Most residential properties in Long Beach are eligible for ADUs, though specific requirements vary. Factors include lot size, setbacks, and existing structures. We provide free consultations to assess your property's ADU potential.
