ADU Construction in Redlands
Adding a backyard cottage, converting your garage, or finishing a junior ADU inside your existing home are all practical ways to put Redlands property to work. Top Tech Builders handles every phase from design through final inspection under one roof, so nothing falls through the cracks between a designer and a subcontractor. We have delivered design-build remodeling and new construction across Southern California since 2019, and that seven years of in-house experience shapes every decision we make on your project.
Whether you are planning a detached unit for a family member or a rental-ready garage conversion, our team moves from permit drawings to finished construction without the handoffs that slow most projects down. If you are in the early planning stage, reach out now so we can frame out your options before costs shift.
Redlands sits in San Bernardino County where triple-digit summer temperatures make insulation thickness, low-solar-gain glazing, and exterior shade detailing non-negotiable on any new living space. Clay soils common in the area expand and contract with seasonal moisture changes, which means foundation and slab design for an ADU requires more attention than a standard pour. Our team accounts for both conditions during the design phase rather than discovering them mid-build. Redlands also carries a mix of older craftsman-era homes and postwar tract lots, so setback configurations and existing utility routing vary widely from parcel to parcel. We assess your specific site conditions before drawing anything, which keeps your project on a realistic schedule and budget from day one. These local factors are part of every ADU conversation we have with Redlands homeowners.
Soil movement is the reason engineered foundations cost more here than the coastal average.

ADU Construction questions from Redlands
- What is the difference between a detached ADU, an attached ADU, and a junior ADU?
- A detached ADU is a fully separate structure on your lot with its own foundation. An attached ADU shares at least one wall with your main home but has its own entrance and kitchen. A junior ADU is carved out of interior space inside the primary residence, typically capped at 500 square feet by state law, and may share some amenities with the main unit. We build all three types and can help you determine which fits your lot and goals.
- How does Redlands clay soil affect my ADU foundation?
- Expansive clay soils shift as moisture levels change through the seasons. A slab or foundation that ignores that movement can crack over time. We engineer the foundation and slab detailing specifically for the soil conditions on your parcel, which may mean deeper footings, post-tension slab design, or other measures determined during site review. This step happens before design is finalized, not after permits are pulled.
- How long does an ADU project typically take from start to finish?
- Timelines vary based on unit type, site conditions, and permit processing speed. A garage conversion often moves faster than a new detached structure because the shell already exists. We give you a project-specific schedule after the site assessment and design scope are established, so you have a realistic picture before any work begins.
- Do I need to hire a separate architect and then a contractor?
- Not with us. Top Tech Builders is a design-build firm, meaning our in-house team handles design, engineering coordination, permitting, and construction. That single-team structure removes the miscommunication that happens when an owner has to manage a separate architect and contractor, and it keeps your project moving on one consistent schedule.
- What should I prepare before our first conversation?
- A copy of your property survey or assessor parcel map is helpful if you have one. A rough sense of your goals, such as rental income, multigenerational living, or a home office, helps us focus the initial scope conversation. You do not need drawings or a finished plan. We gather what we need during the assessment and build the design from there.
