Our ADU Design Build Services

Our ADU design build services are structured to cover every stage of your project—from initial planning and feasibility to final construction and completion. Each service is designed to solve specific homeowner challenges, whether it's navigating Sacramento County permits, optimizing your lot, controlling costs, or ensuring long-term usability. By combining specialized services into one coordinated system, we help you move forward with a clear, efficient, and fully managed ADU project.

Detached ADU Design Build

A complete, ground-up solution for building a fully independent unit in your backyard. This is the most flexible ADU option for homeowners focused on rental income, long-term property value, or private living space for family members.

We plan your detached ADU around Sacramento County lot conditions, including setbacks, access, and utility placement. Every decision is made to ensure your unit is both functional and approvable.

What this includes:

• Site-specific placement strategy for your lot

• Private entrance and circulation planning

• Full foundation, framing, and structural build

• Independent kitchen, bathroom, and living systems

• Utility routing for water, sewer, gas, and electrical

This option works best when you want maximum privacy and long-term flexibility.

Attached ADU Design Build

An attached ADU expands your existing home while maintaining structural connection. This approach is often ideal for homeowners who want to maximize existing space and reduce certain construction complexities.

We design attached units that feel independent while integrating seamlessly with your current home layout.

What this includes:

• Structural integration with existing home

• Efficient footprint planning to reduce unused space

• Shared or partially shared utility strategies

• Interior flow that balances connection and privacy

This is a strong option for multigenerational living or homeowners with limited yard space.

Garage Conversion ADU

Garage conversions are one of the most efficient ways to create livable space from an underutilized structure. However, they still require careful planning to meet building codes and comfort standards.

We transform garages into fully compliant living units.

What this includes:

• Structural review and reinforcement if needed

• Insulation, ventilation, and energy upgrades

• Plumbing and electrical system installation

• Window and natural light improvements

• Interior layout redesign for livability

This is often a faster path to an ADU, but still requires proper design and compliance to avoid costly mistakes.

JADU Design Build

Junior ADUs (JADUs) are compact units typically created within the existing home footprint. They are a practical solution for homeowners looking for lower-cost expansion or flexible living space.

We design JADUs to maximize efficiency without compromising usability.

What this includes:

• Space optimization within existing structures

• Compact kitchen and bathroom planning

• Code-compliant design for smaller units

• Integration with existing home systems

This option is ideal for homeowners who want a simpler, space-efficient ADU solution.

Custom ADU Design and Floor Planning

Every property and homeowner goal is different. Custom design ensures your ADU is not just approved—but actually usable and valuable long-term.

We design around how the space will be used, not just how it fits on paper.

What this includes:

• Layouts tailored for rental, family, or personal use

• Privacy-focused bedroom and living placement

• Storage optimization and functional circulation

• Natural light and ventilation planning

• Future flexibility for changing needs

A well-designed ADU reduces future limitations and increases usability.

Permit-Ready Plans and Approval Support

One of the biggest challenges homeowners face is getting plans approved. Poorly prepared drawings or missing details can delay projects significantly.

We prepare complete, submission-ready documentation aligned with Sacramento County requirements.

What this includes:

• Zoning and setback verification

• Code-aligned plan preparation

• Permit submittal documentation

• Plan check response and revisions

This step is critical for keeping your project moving forward without unnecessary delays.

Structural Engineering and Code Compliance

Engineering ensures your ADU is safe, buildable, and aligned with structural requirements. It also plays a major role in permit approval.

We coordinate engineering early to avoid redesign later.

What this includes:

• Structural calculations and load planning

• Framing and foundation specifications

• Code-compliant structural detailing

• Alignment with local building standards

Strong engineering reduces risk during both approval and construction.

Utility Planning and Coordination

Utility planning is one of the most overlooked parts of ADU projects. Poor coordination can lead to delays, redesigns, or unexpected costs.

We address utilities early in the process.

What this includes:

• Water and sewer connection planning

• Electrical load and panel considerations

• Gas line routing where applicable

• Coordination with local utility providers

This ensures your ADU is fully functional and avoids mid-project complications.

Full Construction and Project Management

We manage the entire build so you are not coordinating multiple contractors or dealing with miscommunication.

What this includes:

• Site preparation and foundation work

• Framing, roofing, and exterior construction

• Plumbing, electrical, and HVAC installation

• Insulation, drywall, and interior finishes

• Final inspections and completion

A managed construction process keeps your project on schedule and aligned with your original plan.

Budget-Conscious and Pre-Approved ADU Options

For homeowners who want a faster or more cost-controlled path, we offer practical design strategies and efficient plan options.

What this includes:

• Pre-approved or simplified plan approaches

• Efficient layouts to reduce construction complexity

• Cost-conscious material and design decisions

• Faster planning and approval pathways where applicable

This approach helps balance budget, timeline, and usability.

ADU Types and Use Cases We Build For

Every homeowner has a different reason for building an ADU, and the right design depends on how the space will actually be used. Whether you're focused on rental income, supporting family members, or creating flexible living space, each use case requires a specific approach to layout, privacy, and long-term functionality. Our process ensures your ADU is designed not just for approval—but for real-life use within Sacramento County property conditions.

Rental Income ADUs

For homeowners focused on turning their property into a long-term income-producing asset, rental ADUs must be designed with both tenant experience and durability in mind.

We plan these units to perform over time—not just look good initially.

Key considerations:

• Private entrances and separation from the main home

• Efficient layouts that maximize rentable space

• Durable materials that reduce maintenance costs

• Kitchen and bathroom configurations suited for long-term tenants

• Layouts aligned with Sacramento County rental expectations

This approach helps create a unit that attracts tenants, minimizes turnover issues, and supports consistent income.

Multigenerational Family ADUs

These ADUs are designed for families who want to stay close while maintaining independence and personal space. The challenge is balancing proximity with privacy.

We design these units around real daily living needs.

Key considerations:

• Separate entrances for independence

• Comfortable living and sleeping arrangements

• Functional kitchens and bathrooms for daily use

• Sound separation and privacy-focused layouts

• Accessibility considerations for different age groups

This is a practical solution for families supporting aging parents, adult children, or extended relatives.

Aging-in-Place ADUs

Aging-in-place ADUs require thoughtful planning to ensure safety, comfort, and usability over time. These are not standard layouts—they must anticipate future mobility and lifestyle needs.

We design these units for long-term livability.

Key considerations:

• Single-level layouts to eliminate stairs

• Wider pathways and accessible design features

• Easy-to-use kitchen and bathroom layouts

• Safe entry and exit points

• Space planning that supports future adaptability

This ensures the ADU remains functional and comfortable for years to come.

Guest House and Backyard Cottage ADUs

These units offer flexibility for homeowners who want immediate personal use with future adaptability. They can serve as guest housing today and transition into rental or family space later.

We design these ADUs with versatility in mind.

Key considerations:

• Comfortable short-term living layouts

• Balanced privacy between main home and ADU

• Flexible interior spaces for different uses

• Design choices that support future conversion to rental use

This option works well for homeowners who want both lifestyle benefits and long-term property value.

Home Office or Studio ADUs

These ADUs are designed for productivity, privacy, and focus. They provide a dedicated space separate from the main home, which is especially valuable for remote work or creative use.

We design these units to support both current and future use cases.

Key considerations:

• Quiet, distraction-free layouts

• Natural light and ventilation for daily use

• Flexible space for office, studio, or hybrid living

• Infrastructure that allows future conversion into a full ADU

This creates a space that works as an office today and a livable unit in the future.

Step-by-Step ADU Design Build Process
