Accessory Dwelling Unit and Small Lot Development
Accessory dwelling units and SB9 development projects allow property owners to expand residential housing opportunities while increasing the long-term value of their property.
These projects require careful planning, architectural design, engineering, permitting, and organized construction management.
Our team manages ADU and SB9 development through a structured process that integrates architectural planning, engineering services, and disciplined construction execution from early planning through project completion.
ADU Construction
Accessory dwelling units provide additional residential living space on an existing property.
ADU construction includes:
- Detached accessory dwelling units
- Attached ADU additions
- Garage conversions
- Guest house construction
- Backyard residential units
Each project is developed through architectural planning, engineering review, and structured construction management to ensure the project progresses efficiently and meets all building and permitting requirements.
SB9 Development
SB9 development allows residential properties to be divided or developed to support additional housing.
SB9 development projects include:
- Residential lot split development
- Construction of multiple residential units
- Redevelopment of existing residential properties
- Development of additional housing units on qualifying parcels
SB9 projects require architectural planning, engineering design, and careful permitting review to ensure the development complies with local planning requirements.
Architectural Plans and Development Drawings
ADU and SB9 development projects require architectural plans that define the layout, structure, and design of the proposed residential units.
Our team prepares architectural plans and development drawings that establish the foundation for engineering review, permitting approvals, and construction execution.
Architectural planning services include:
- Residential architectural layouts
- ADU development plans
- Construction drawings prepared for permitting
- Site and building plan preparation
- Integration with structural engineering requirements
Engineering and Structural Design
Structural engineering ensures ADU and SB9 development projects meet safety standards and building code requirements.
Engineering services include:
- Structural design and calculations
- Foundation design and planning
- Structural load analysis
- Construction plans prepared for permitting
Engineering planning ensures construction plans meet building requirements and move efficiently through the permitting process.
Our Development Process
Site Evaluation
The process begins with reviewing the property, evaluating site conditions, and establishing development objectives.
Planning
During the planning phase architectural plans are prepared, engineering requirements are reviewed, and permitting requirements are addressed.
Construction
Construction work proceeds through organized scheduling, disciplined project management, and consistent project oversight.
Completion
Final inspections and walkthroughs confirm the completed development meets construction standards and project requirements.
Frequently Asked Questions
An accessory dwelling unit is a secondary residential structure located on the same property as an existing home. ADUs provide additional living space and are commonly used as guest houses, rental units, or housing for family members.
SB9 is a California housing regulation that allows certain residential properties to be subdivided or developed with additional housing units. SB9 development may include lot splits or the construction of multiple residential units on qualifying parcels.
The number of ADUs permitted on a property depends on zoning regulations, lot size, and local planning requirements. A review of the property helps determine the development potential and the number of units allowed.
Yes. ADU and SB9 development projects require permits and inspections from local building departments. Architectural and engineering plans are reviewed during the permitting process to confirm compliance with building codes and planning regulations.
Yes. Garage conversions are one of the most common types of accessory dwelling unit construction. The existing structure is modified and upgraded to meet residential building standards.
The first step is reviewing the property and discussing development goals. This evaluation helps determine the development potential of the property and establishes the planning steps required before architectural design and construction begin.
