Types of ADUs: Detached, Attached, Junior, and Modular
We offer several types of Accessory Dwelling Units (ADUs) suited for different needs and property layouts in Bluff Heights, where 73% of residents rent rather than own their homes.
- Detached ADUs are standalone structures separate from the main house. They provide privacy and can be designed to match the primary home's style, often complementing the Craftsman bungalow aesthetic common in this historic district.
- Attached ADUs share a wall with the main residence. They often use existing space like garages or basements, offering convenience and integration while preserving the neighborhood's dense urban feel.
- Junior ADUs (JADUs) are smaller units within the main home, typically under 500 square feet. They usually share some utilities with the primary residence but have separate entrances, ideal for the many young professionals who live in Bluff Heights.
- Modular ADUs are prefabricated off-site and assembled on your property. This method can reduce construction time while maintaining quality and customization, essential in a neighborhood with limited space between properties.
Our team uses only high-grade, contractor-quality materials that exceed California building code requirements. All lumber, concrete, wiring, plumbing fixtures, and finishing materials meet rigorous quality standards and come with appropriate warranties.
The ADU & Garage Conversion Process
Our established reputation includes successful completion of ADU projects in the Long Beach area. We guide clients through every stage of ADU construction and garage conversions, ensuring clarity from design to installation. Our comprehensive service menu includes architectural design, engineering, permitting, construction, and interior finishing, all backed by our standard 5-year workmanship warranty.
Project Visualization and Design Consultation
We begin by visualizing your ideal ADU through detailed architectural design consultations. Our in-house architectural team collaborates closely to create precise plans that fit your property's unique layout and comply with local regulations in this historic district with its specific architectural heritage.
Using advanced project visualization tools, we present 3D renderings and schematics that clarify the final structure's look and function. This step lets you make informed decisions before construction starts, reducing costly changes later in a neighborhood where the median rent is $1,895.
Site Evaluation and Permit Application
After design approval, we conduct a comprehensive site evaluation to assess soil, grading, and existing utilities. This analysis ensures the ADU or garage conversion integrates seamlessly with your lot's specifics, especially important in Bluff Heights' relatively flat terrain.
We handle all permit applications involving city and county authorities in Long Beach. Our experienced permitting specialists maintain excellent relationships with
local building departments and understand the nuances of Bluff Heights' permit codes. This expertise expedites approvals, minimizing delays in your project timeline in this diverse neighborhood with high liberal-leaning demographics.
By combining our knowledge of ADU site evaluation and local regulations, we prepare all documentation required, including architectural drawings and engineering reports. This step guarantees your build meets all safety and zoning standards while respecting the neighborhood's historic character.

Our team includes specialized professionals with certifications in their respective trades, ensuring your project receives expert attention at every stage. We ensure precision in foundation preparation, utility hookups, and final assembly in Bluff Heights' year-round moderate climate with temperatures ranging from 55°F in winter to 75°F in summer.
For prefab or shipping container ADUs, our team coordinates shipping and on-site setup efficiently, reducing installation time without compromising quality. We follow strict protocols for structural integrity and code adherence within the neighborhood's boundaries (Broadway to the south, 4th Street to the north, Junipero/Wisconsin Avenue to the west, and Redondo Avenue to the east).

Key Structural and System Installations
Our process prioritizes precise foundation work, durable framing, and robust systems installation to ensure your ADU or garage conversion meets safety and comfort standards. We integrate structural engineering assessments and expert craftsmanship in every phase to deliver lasting results. All materials used exceed California building code standards, and installations are performed by experienced tradespeople with relevant certifications.
Foundation Grading and Framing
We begin with foundation grading, carefully leveling the site to direct water away from the structure and prevent future settling issues. Our structural engineering assessment guides the foundation design, commonly involving a concrete slab foundation tailored for ADU construction in Bluff Heights' coastal-adjacent area.
The framing phase uses quality materials assembled to support roofing loads and exterior siding, emphasizing durability and alignment with the initial engineering plans. All lumber meets structural grade requirements and is treated appropriately for the local climate conditions.
Roofing and Siding
We install roofing and siding materials that withstand Bluff Heights' coastal climate with its predictable seasons and low annual rainfall of about 12 inches. Our suppliers provide industry-leading warranties on all roofing materials, ensuring long-term protection and peace of mind.
Siding installation complements roofing by using weather-resistant materials appropriate for the mild climate. We also handle interior drywall to create finished, insulated surfaces, including soundproofing insulation where needed for privacy in this densely populated urban setting.
Plumbing, Electrical, and HVAC Systems
Our team performs complete systems installation, including plumbing line setup, sewer connections, and electrical rewiring to meet occupant needs and safety codes in this vibrant community with numerous restaurants, coffee shops, and bars. All work is performed by licensed professionals who understand local code requirements.
We focus on efficient plumbing system installation for kitchens and bathrooms within conversions. The electrical system installation incorporates modern wiring and fixtures to support appliances and lighting needs in the moderate climate.
For climate control, we specialize in HVAC system setup, including mini split installation to provide efficient heating and cooling without ductwork, which is ideal for ADUs and garage conversions in Bluff Heights' mild weather.
Efficiency, Safety, and Finishing Touches
We prioritize creating ADUs and garage conversions that meet modern standards for comfort, protection, and aesthetics. Our approach balances energy-saving features, essential safety measures, and high-quality interior finishes to deliver well-rounded living spaces.
Energy Efficiency and Soundproofing
We use energy-efficient materials and systems to reduce utility costs and environmental impact in a neighborhood where environmental awareness is important.
Our projects often include double-pane windows, LED lighting, and Energy Star-rated appliances to increase efficiency. We also install soundproofing insulation in walls and ceilings to minimize noise transfer, improving privacy for occupants in this lively area known for its A+ rated nightlife.
Safety Systems and Fire Protection
Safety is a top priority in every build. We install smoke detectors, carbon monoxide alarms, and fire extinguishers according to California building codes. Our safety systems installation includes proper emergency exits, fire-rated doors, and sprinkler system integration when required.
We ensure all electrical wiring and gas lines meet code standards to prevent hazards. These measures safeguard occupants and help meet local fire safety regulations in this historic neighborhood with its early 20th-century infrastructure.
