Our ADU Construction Services
We handle every stage of accessory dwelling unit projects, from design to final inspection. Our team focuses on efficient layouts, durable materials, and compliance with Santa Monica building codes to ensure each unit meets both functional and legal requirements.
Custom ADU Design
We create floor plans that match the size of your lot and the way you plan to use the space. Our design process includes site evaluation, layout planning, and material selection.
We work with you to decide on room sizes, storage options, and natural light placement. We also account for plumbing, electrical, and HVAC needs during the planning stage to reduce costly changes later.
Our designs follow California ADU regulations, including height limits and setback rules. We provide detailed drawings for city approval and use 3D renderings so you can see the layout before construction begins.
Garage Conversion Solutions
We convert existing garages into fully functional living spaces that meet safety and zoning standards. This includes structural reinforcement, insulation upgrades, and utility installations.
We inspect the current structure to check for foundation cracks, roof issues, or termite damage. If repairs are needed, we address them before starting the conversion.
Our team manages all permit applications with the City of Santa Monica. We ensure the converted space has proper ventilation, waterproofing, and energy-efficient systems to comply with California Title 24 energy codes.
Detached and Attached ADUs
We build both detached units for more privacy and attached units that share a wall with the main home. The choice depends on your lot size, budget, and intended use.
For detached ADUs, we handle grading, utility trenching, and separate entrances. These units often require more site work but allow for more design flexibility.
For attached ADUs, we integrate the new space with the existing structure while maintaining fire safety and soundproofing standards. We also ensure the addition blends with your home’s exterior style through matching finishes and rooflines.
ADU Design and Planning Process
We focus on creating accessory dwelling units that meet local codes, fit the property, and match the homeowner’s needs. Our approach addresses site conditions, design requirements, and city regulations from the start to avoid delays and costly changes later.
Site Assessment and Consultation
We begin by visiting the property to evaluate its layout, access points, and utility connections. This helps us determine the best location for the ADU and identify any space or zoning limitations.
During the consultation, we review your goals, budget, and timeline. We also check Santa Monica’s ADU size limits, setback rules, and parking requirements.
We use this information to outline feasible design options. This step ensures the project is realistic before moving into the design phase.
Architectural Design Services
Our design team creates floor plans that balance function, comfort, and compliance with city standards. We focus on efficient layouts that make the most of the available space while maintaining privacy and natural light.
We prepare detailed drawings that include dimensions, materials, and structural elements. These plans are tailored to your property’s measurements and the city’s ADU guidelines.
We also offer 3D renderings so you can see how the finished unit will look. This helps confirm the design before we move forward with permits.
Permit Acquisition Assistance
Santa Monica has specific requirements for ADU permits, including building, electrical, plumbing, and sometimes coastal review. We handle the preparation and submission of all necessary documents to the city.
Our team communicates with local planning and building departments to address questions or revisions. This reduces the risk of application rejection or delays.
We track the permit process from start to approval, keeping you informed of each step. In managing this process, we help ensure construction can begin without unnecessary interruptions.
Santa Monica ADU Zoning and Regulations
In Santa Monica, building an ADU requires following both city zoning codes and state housing laws. We must account for factors such as lot size, setbacks, height limits, and parking rules while also meeting California’s uniform ADU standards.
Local Zoning Requirements
Santa Monica’s zoning rules control where and how we can build an ADU. Most residential zones allow ADUs, but the placement, size, and design must match local code.
Setback rules often require at least 4 feet from side and rear property lines. Height limits vary but typically range from 16 to 25 feet depending on the type of ADU.
Parking requirements may apply unless the property is near public transit or in certain exempt zones. We also must ensure the ADU does not exceed the city’s maximum lot coverage or floor area ratio.
Design review may be required for certain neighborhoods, especially in historic districts. This can affect exterior finishes, roof style, and window placement to maintain neighborhood character.
Compliance With California ADU Laws
California law sets baseline ADU regulations that all cities, including Santa Monica, must follow. These laws override local rules that are more restrictive than state standards.
State law allows at least one ADU and one Junior ADU per lot in single-family zones. It also limits local review timelines to 60 days for complete applications.
We follow state size minimums, which permit detached ADUs up to 1,200 square feet, regardless of local limits, unless safety or utility constraints apply.
Owner-occupancy requirements are not allowed for most ADUs approved between 2020 and 2030. This flexibility makes it easier for property owners to rent or use the unit as needed.
Sustainable and Energy-Efficient ADUs
We design ADUs that reduce environmental impact while lowering long-term utility costs. Our approach focuses on using durable, eco-friendly materials and integrating systems that use less energy without sacrificing comfort or function.
Green Building Materials
We choose materials that last longer and require less maintenance. This reduces waste and the need for frequent replacements. For example, we often use fiber cement siding, which resists rot, pests, and fire.
Whenever possible, we source FSC-certified wood to ensure responsible forestry practices. We also use low-VOC paints and finishes to improve indoor air quality. These products release fewer harmful chemicals into the home.
Our flooring options include bamboo and recycled-content tile. These materials are renewable or made from reclaimed sources, which helps conserve resources. We also use insulation made from recycled materials, such as denim or cellulose, to improve thermal performance.
By selecting products with high durability ratings, we help ensure that the ADU remains in good condition for decades. This reduces both environmental impact and long-term costs for the homeowner.
Energy-Saving Features
We design each ADU with systems that use less energy while maintaining comfort. This includes LED lighting throughout the home, which uses up to 75% less electricity than traditional bulbs.
Our builds often include Energy Star–rated appliances, which meet strict efficiency standards. We also install high-performance windows with low-E coatings to reduce heat transfer and improve insulation.
For heating and cooling, we recommend mini-split HVAC systems. These units allow for zoned temperature control and use less energy than traditional systems. In some projects, we integrate solar-ready roofing so homeowners can easily add panels in the future.
We also focus on tight building envelopes with proper sealing to prevent air leaks. This improves energy efficiency and helps maintain a consistent indoor temperature year-round.
Financing and Cost Transparency
We provide clear pricing and payment options so you can plan your project with confidence. Our approach focuses on accurate estimates and flexible financing to match different budgets and timelines.
Detailed Cost Estimates
We start with a thorough site assessment to understand the scope of work. This includes checking zoning rules, utility connections, and structural requirements.
Our estimates break down costs into clear categories:
| Category | Example Costs* | Notes |

*Actual costs vary by project.
We also provide a timeline with cost milestones so you know when payments will be due. This prevents surprises and helps you manage cash flow during construction.
Flexible Financing Options
We offer several financing paths to make your ADU more affordable. This includes partner programs with local lenders who understand ADU projects in Santa Monica.
Options may include:
- Home equity loans for lower interest rates
- ADU-specific renovation loans with extended terms
