thorough site analysis, and expert handling of permits and structural requirements specific to this San Gabriel Valley location.


Custom ADU Architectural Design and 3D Renderings


Our custom ADU architectural design focuses on creating floor plans that maximize functionality while reflecting your style preferences in Temple City's mild year-round climate with minimal rainfall of just 18 inches annually. We use advanced 3D rendering software and premium design materials to visually represent your ADU at various stages, allowing you to see realistic designs before construction begins in this seismically active region requiring specialized engineering considerations.


This process helps identify any necessary adjustments early, ensuring your ADU layout, room sizes, and features align with your goals in a city with an average household size of 3.03 people. Our licensed architects incorporate energy-efficient design principles and specify quality building materials that withstand Southern California's climate conditions. 


Site Evaluation and Space Optimization


We conduct thorough site evaluations to assess factors such as lot size, topography, existing structures, and utility connections in Temple City's relatively flat terrain at the base of the San Gabriel Mountains. This evaluation informs how we optimize the available space for maximum efficiency and use in properties averaging 3,025.1 housing units per square mile.


Our certified professionals analyze sun orientation, setbacks, and access points, designing ADUs that blend with your property and local environment while taking advantage of Temple City's 280+ sunny days per year. We use professional surveying equipment and soil analysis tools to ensure proper foundation planning. Space optimization goes beyond square footage, focusing on logical room placement, flow, and usability to deliver a practical living environment in this walkable community served by the Pacific

Electric Railway heritage.


Zoning, Code Compliance, and Permitting Assistance


Navigating local zoning laws and building codes is crucial to a successful ADU project in Temple City, which has faced recent scrutiny from California state housing officials regarding SB9 compliance. Our licensed professionals guide you through zoning verification, code compliance reviews, and all necessary permit applications to keep the project on schedule while avoiding the regulatory challenges that have resulted in zero SB9 applications in the city.


Our bonded team handles communication with Temple City authorities and ensures your plans meet requirements such as setbacks, height limits, and occupancy rules. We maintain current certifications and stay updated on evolving regulations. Proper permit processing reduces risks of delays or fines, keeping your project legally sound from start to finish in this city incorporated in 1960.


Structural Engineering and Project Visualization


We integrate structural engineering early in the design phase to verify the stability and safety of your ADU in Southern California's seismic zone where earthquakes are a consideration for all construction projects. Our licensed structural engineers design structures using premium materials that comply with seismic, foundation, and material standards specific to this region

historically known as "Rio de los Temblores" or River of the Earthquakes.


Alongside engineering, we offer advanced project visualization tools like detailed models and animations created with professional software. These tools provide clarity on construction methods and high-quality materials, helping you make informed decisions and anticipate the completed ADU's impact on your property in Temple City's family-oriented neighborhoods where 37.9% of households have children under 18.


Types of ADU Construction Offered


We provide a range of ADU construction options tailored to fit different properties and homeowner needs in Temple City's diverse housing stock. Our expertise covers both new builds and conversions using quality materials and proven construction methods, allowing us to deliver efficient, code-compliant, and practical living spaces in this community where the average family size is 3.39 people.


Detached and Attached ADU Construction


We build both detached and attached ADUs using premium framing lumber, energy-efficient windows, and durable roofing materials to maximize your property's potential in Temple City's year-round mild weather with winter lows rarely dropping below 40°F and summer highs typically staying below 90°F. Detached ADUs are standalone units, often placed in the backyard, offering privacy and flexibility for multi-generational families. Attached ADUs connect directly to the main house, such as through a side or rear addition, which can simplify utilities and access.


Both types allow customization including two-story ADUs, custom roofing with high-grade materials, and layout designs that complement Temple City's architectural heritage dating back to the 1920s. We use quality insulation, professional-grade electrical systems, and efficient plumbing fixtures while maintaining neighborhood aesthetics and meeting local zoning and building codes. Our licensed contractors ensure all work meets or exceeds industry standards.

Garage Conversion ADUs


Garage conversions transform existing garage spaces into fully functional ADUs using quality flooring, insulation, and finish materials, a popular option in Temple City where many of the 12,117 housing units feature underutilized garages. This cost-effective option minimizes changes to the property footprint while our licensed professionals handle all aspects, including structural upgrades, premium insulation, plumbing, and electrical work to convert garages into legal, livable spaces.


Garage conversions often include adding energy-efficient windows, high-performance insulation, and efficient layouts to maximize comfort in Temple City's Mediterranean climate that rarely requires extensive heating or cooling. We use moisture-resistant materials and proper ventilation systems. Our insured team ensures compliance with local regulations and provides tailored finishes using quality materials to meet your needs in this community known for its annual Camellia Festival each February.


Basement, Above-Garage, and Junior ADUs


Basement ADUs require careful structural and waterproofing workmanship using specialized materials to convert below-grade spaces into legal living units, though these are less common in Temple City's generally flat topography. Our licensed contractors reinforce foundations and install ventilation while upgrading electrical and plumbing systems using quality components for effective use in the region's low-humidity environment.


Above-garage ADUs take advantage of existing roof space to build second-story ADUs using engineered lumber and quality roofing materials, providing additional square footage without expanding the home's footprint in this densely populated city. Junior ADUs are smaller units, usually up to 500 square feet, often created from interior spaces using efficient design and quality finishes while requiring fewer permits.


Modular, Prefab, and Shipping Container ADUs


Modular and prefab ADUs offer faster construction times and predictable costs using factory-quality materials and precision manufacturing, important considerations in Temple City's competitive construction market. Pasadena Master ADU Builder handles the modular ADU construction and installation process, assembling factory-built sections on your property with precision while taking advantage of the area's stable, dry climate that allows for year-round construction.


Shipping container ADUs are durable and eco-friendly options using steel construction and quality conversion materials. We customize containers with premium insulation, efficient plumbing, and professional electrical work to create modern, functional homes. These options suit clients looking for efficient, pre-approved plans and flexible designs using innovative materials without sacrificing quality.

Attached and Detached Garage-to-Living Space Conversions


Pasadena Master ADU Builder handles both attached and detached garage conversions, transforming them into bedrooms, home offices, guest suites, or rental ADUs using quality flooring, lighting, and finish materials. For attached garages, our licensed professionals ensure proper fire-rated separation from the main house using code-compliant materials and address the removal of garage doors with new wall framing using premium lumber.


Detached garage conversions require careful structural assessments and foundation checks in this seismically active region. Our bonded team prepares architectural drawings and manages permit applications to secure compliance with Temple City regulations. We prioritize energy-efficient window and door installations using quality products to improve comfort and reduce utility costs in the mild but sometimes warm summer months when temperatures can reach the mid-80s.


Specialized Room Conversions and Insulation


Our services include conversion of garages into specialized spaces such as fitness rooms, home theaters, or in-law units using soundproofing materials and custom finishes. We customize wall and ceiling treatments using quality framing materials, refinishing products, and soundproofing when necessary.


Proper insulation using high-performance materials is critical for year-round comfort in Temple City's Mediterranean climate with

cool, wet winters and warm, dry summers. Our licensed installers use quality wall and ceiling insulation combined with moisture barrier systems to maintain indoor climate stability. This attention to detail using premium materials enhances energy efficiency and ensures long-term durability of the converted space.


Garage Foundations, Roofing, and Exterior Modifications


We assess and level concrete slabs using professional-grade materials to provide stable, even flooring for your new living space, ensuring compliance with seismic safety standards important in this earthquake-prone region of Southern California. Our licensed contractors conduct structural evaluations covering foundation integrity and framing using quality materials to support the conversion safely.


Roof modifications may include extensions, adjustments, or new roofing materials using weather-resistant products to match the existing profile and enhance weather resistance during Temple City's occasional winter rains and strong Santa Ana winds. Exterior work involves removing garage doors, constructing new walls using quality lumber, and finishing surfaces with matching or upgraded siding using durable materials to maintain property values in this community where the median age is 42.0 years.
