ADU Site Evaluation

Before breaking ground on your accessory dwelling unit, understanding your property's full potential is essential. At Modern ADU Builder & Garage Conversions, our specialized ADU site evaluation service provides the foundation for successful ADU development in Long Beach's unique building environment.


Our comprehensive evaluation process examines crucial factors that impact your project's feasibility, design options, and budget. We analyze topography, soil conditions, existing structures, utility locations, and access points while identifying potential challenges that could affect construction. Our experienced evaluators measure setbacks, verify zoning compliance, and assess for optimal ADU placement specific to your property's characteristics.


This critical first step prevents costly surprises during the design and construction phases. Many Long Beach homeowners discover untapped potential they hadn't considered—from ideal positioning that preserves yard space

to innovative solutions for challenging lots that other contractors might dismiss.


Our detailed evaluation report provides actionable insights on recommended ADU types, approximate size potential, estimated utility connection requirements, and preliminary budget considerations based on site conditions. We highlight permitting considerations specific to your location within Long Beach's varied neighborhoods.


Whether you're considering a detached backyard ADU, garage conversion, or attached addition, our site evaluation service ensures your project begins with confidence, clarity, and a solid understanding of your property's unique opportunities and constraints.

Our Comprehensive Evaluation Process

Our evaluation process for ADUs is thorough and ensures all aspects of your property are considered. We focus on consultation, compliance with local regulations, and infrastructure needs to provide a comprehensive understanding of your site.

  • 1. Initial Consultation

    The first step in our evaluation process is the initial consultation. During this meeting, we discuss your vision and goals for the ADU. We assess your property's current conditions, including size, layout, and existing structures.


    We take detailed notes and measurements. This enables us to identify any unique features or challenges that may affect the design and construction of your ADU. Our team considers factors such as sunlight, accessibility, and landscaping. By the end of this stage, we create a foundation for our planning.

  • 2. Zoning and Code Compliance

    Zoning regulations and building codes play a crucial role in ADU development. Our team conducts a detailed analysis to ensure your project complies with local laws. We review zoning requirements, including setback regulations, height limits, and density restrictions specific to Long Beach.


    This step involves checking each law that might impact the project. We will outline necessary permits and paperwork required for your approval. Understanding these factors early helps us avoid potential delays and costly modifications during construction.

  • 3.Utility Access

    Utility access is vital for the successful installation of an ADU. We examine the existing infrastructure related to water, electricity, gas, and sewage on your property. Understanding how these utilities can be connected to your new ADU is essential to avoid service interruptions.


    Our team evaluates the capacity and condition of existing systems. If upgrades are necessary, we will provide you with options and recommendations tailored to your project needs. Our thorough review ensures that all essential utilities are properly managed for a seamless integration into your property.
