Learn MoreComprehensive Land Survey & Civil Engineering for ADUs
Our land survey and civil design teams assists property owners, developers, Architects and ADU builders in navigating the complexities of ADU construction. We ensure compliance with local zoning regulations, building codes, easements, and property boundaries. We also offer the following services specifically designed for ADU projects:
Land Survey
Property & Boundary Drawings: Accurate delineation of all property features and boundaries is essential for ADU development to avoid encroachments and legal disputes. Our surveyors employ advanced surveying techniques, including photogrammetry and boundary monumentation research to precisely define property lines and establish clear demarcations. We prepare detailed survey maps and legal descriptions compliant with local regulations, providing the foundation for permitting and construction processes.
Site Analysis: Before embarking on an ADU project, it’s crucial to assess the site’s suitability and feasibility. Our surveyors conduct a detailed site analysis, provide factors such as lot size, setbacks, access points, and existing utilities. We discuss the opportunities and constraints associated with ADU development, helping clients make informed decisions prior to construction.
Utility & Infrastructure Verification: ADU development often requires modifications to existing utility infrastructure, such as water, sewer, and electrical systems. Our surveying team field locates all existing utilities to support the additional dwelling unit. Our survey helps to coordinate with utility providers and municipal agencies to ensure compliance with regulations and streamline the permitting process.
Civil Engineering
Grading/Drainage Analysis & Design: Proper site grading and drainage are critical for mitigating water-related issues and ensuring the stability of ADU structures. After our surveyors complete their detailed topographic surveys, our Civil Engineering team will minimize erosion, water intrusion risks, integrate sustainable stormwater management practices, such as permeable paving and rainwater harvesting, to enhance site resilience and environmental sustainability.
ADU Design Support: Our civil engineering support extends throughout ADU design, permitting and the construction processes. We collaborate with architects, engineers, jurisdictions and contractors to incorporate site-specific data into ADU designs, optimizing layout, orientation, and spatial relationships. Our surveyors provide valuable information and work with our civil team on site planning, foundation design, and construction phasing, facilitating efficient project execution and minimizing construction costs.
