Detached Accessory Dwelling Unit (ADU) Design & Permit Plans
El Cajon, California
1,000 SF Detached ADU

Project Overview
This 1,000 SF detached Accessory Dwelling Unit (ADU) project at 1536 Mint Avenue, El Cajon, California 92019 features a coordinated permit drawing package developed for a residential property. The scope incorporates architectural planning, site integration, structural documentation, elevations, roof and foundation systems, and building-system requirements. The design coordinates the proposed ADU with existing site conditions, property setbacks, utilities, access, and drainage while addressing applicable California building, residential, energy, and CALGreen requirements. The resulting documentation provides a clear, coordinated foundation for ADU permit review and construction in El Cajon, CA.
Project Scope
Design and documentation of a 1,000 SF detached residential ADU, including site planning, floor plans, exterior elevations, roof plans, building sections, structural foundation and framing systems, construction details, and coordinated building-system requirements. The scope also addresses site setbacks, utilities, drainage, access, and applicable California code requirements to support permit review and construction in El Cajon, CA.
Project Challenge
Developing a complete 1,000 SF detached ADU within an existing residential property required careful coordination of the new structure with existing site conditions, property setbacks, utilities, access, drainage, and applicable California building and energy requirements.
Our Solution
A coordinated permit drawing package was developed integrating the architectural layout, site planning, foundation and structural framing, roof system, construction details, and building-system requirements into a clear set of documents for the proposed El Cajon ADU.
The Outcome
A comprehensive and coordinated ADU design and permit documentation package that clearly communicates the proposed building, structural systems, site relationships, and construction requirements to support permit review and project execution.
