ADU CONSTRUCTION
THOUGHTFULLY DESIGNED AND BUILT ADUS, GUIDED BY CLEAR PLANNING, SMART DESIGN, AND A PROCESS CENTERED AROUND HOW YOU WANT TO LIVE.
More space. More possibility. Built with intention.
An ADU isn’t just extra square footage it’s possibility. It’s the quiet separation that brings families closer, the private space that lets creativity breathe, the rental unit that supports your long-term plans, or the retreat that makes your home feel bigger without ever leaving the neighborhood.
At Heart Construction, we approach ADUs the same way we approach custom homes: with intention, clarity, and a genuine understanding of the lifestyle behind the project. We listen to why this space matters family, income, flexibility, future planning and we shape the design and build around it. The result is an ADU that feels natural, connected, and purpose-built for the way you want to live.
Cost is one of the biggest questions homeowners have when considering an ADU. We explain typical budgets and what affects pricing in our guide to ADU cost in Los Angeles.
ADU DESIGN & BUILD IN LOS ANGELES
ADUs in California: One of the Smartest Investments You Can Make
California and Los Angeles in particular have become the epicenter of the ADU movement, driven by new statewide laws designed to support homeowners. ADUs are now one of the highest-ROI improvements you can make to a property in Los Angeles, offering:
Fast-track permitting in many cities
By-right approvals with fewer obstacles
Reduced or eliminated impact fees for many ADUs
Flexible rental opportunities
Significant increases in property value
A long-term solution for multigenerational living
For many homeowners, an ADU becomes a lifelong asset — a space that evolves with your needs. Whether you're creating a rental, a workspace, a private suite, or a calm retreat for family, an ADU adds both function and value in a way few home improvements can.
Before moving forward, it’s worth understanding what your property actually supports — and how those factors shape cost, feasibility, and design. We break that down in our ADU decision guide for Los Angeles homeowners.
Our ADU Process Simple, Thoughtful, Predictable
A detailed, transparent roadmap from dream to reality.
Below is our full process, broken down clearly so you always know what happens long before it happens.
We begin by understanding how you intend to use the ADU a guest suite, a rental unit, creative studio, workspace, or multigenerational living. Then we evaluate zoning, setbacks, property layout, access, and feasibility to confirm what is possible — the same factors we outline in our ADU decision guide for Los Angeles properties.
Discovery & Planning
1
Design, Budget & Timeline Alignment
2
We collaborate with your architect or bring in one of our trusted design partners to create a plan that fits your goals and budget. During this phase, we also outline milestone-based payments, keeping the financial process clear, structured, and predictable.
Permits & Engineering
3
We manage all permitting, engineering, Title 24 compliance, and ADU-specific requirements. LA permitting can be complex but our experience keeps the process moving smoothly while keeping you fully informed.
4
This is where intention meets execution. We maintain a clean job site, communicate weekly, and work with transparency so there are no surprises. When changes come up, we review the cost, timing, and implications with you before any work proceeds.
Construction
Living Through the Build
5
Because most ADUs are detached or converted from existing structures, homeowners can continue living comfortably during construction. We coordinate work hours, deliveries, materials, and parking to keep disruption to a minimum.
Finishing, Walkthrough & Turnover
6
We walk the completed ADU together, refine the details, and make sure everything aligns with the original vision. The result is a space that feels intentional, functional, and seamlessly integrated into your property.

How these ADUs came together
Every ADU project follows a process, but no two properties start from the same conditions.
Lot configuration, existing structures, zoning, and how the space will be used all shape the decisions along the way.
HANCOCK PARKHancock Park Historical Home + ADU Integration
In this project, the challenge was integrating new living space without compromising the character of a historic home. The ADU and garage were designed to feel like a natural extension of the property, balancing preservation, functionality, and modern living within a highly sensitive architectural context.
CULVER CITYCulver City Home Remodel + ADU Conversion
This project approached the ADU as part of a larger strategy. By restructuring the main home and converting existing space, the property gained flexibility for guests, rental potential, and long-term use without expanding the footprint.

Frequently Asked Questions About ADUs in California
-
Most ADUs take 4–8 months from construction start to completion, depending on design complexity, ADU type, and permitting timelines. Detached ADUs and two-story builds typically take longer than garage conversions or JADUs. We provide a realistic timeline during the planning phase so you know what to expect before construction begins. We break it down clearly in our guide to ADU construction timelines in Los Angeles.
-
Yes — often significantly. ADUs are considered one of the strongest property investments available in Los Angeles, particularly given California's housing demand. A well-designed ADU can add meaningful appraised value, generate rental income, and expand the long-term flexibility of the property.
-
In most Los Angeles zones, yes. ADUs can be rented long-term, and many homeowners use them to offset mortgage costs or build rental income over time. Short-term rental rules vary by city and neighborhood — we help you understand what's possible for your specific property during the planning phase.
-
Yes — permitting and engineering are fully managed as part of our service. We handle all city submittals, Title 24 compliance, ADU-specific requirements, inspections, and any resubmittals needed. LA permitting can be complex, but our experience keeps the process moving without putting that burden on you.
-
For most ADU projects, disruption is minimal. Because ADUs are typically detached or converted from existing structures, you can continue living in your home throughout construction. We coordinate work hours, deliveries, and site access around your schedule to keep daily life as normal as possible.
-
Yes. We work seamlessly with your existing architect or designer, or we can connect you with trusted ADU design partners we collaborate with regularly. Either way, we make sure the design is buildable, functional, and aligned with your goals before construction begins. read more about our approach to design in our Design Build page.
