Seedling ADU Builders plans and builds accessory dwelling units, garage conversions, and home additions in Maywood, CA. Nearly every job here starts with one question: what fits on a 2,500 to 3,500 square foot lot without crowding the home that’s already there. Maywood’s tight lots, older bungalows, and specific setback rules shape every decision we make, from the first site visit to the final walkthrough. Call (626) 657-5461 to talk through what’s possible on your lot.
Why Maywood Homes Are Different
Maywood’s housing stock runs small and old. Most homes are single-story bungalows and modest wood-frame builds from the 1920s through the 1950s, sitting on lots that are unusually narrow. A standard 20-foot-wide detached ADU often won’t fit between side setbacks, which pushes most homeowners toward attached conversions or compact second-story additions. We check lot width before sketching anything.
The mild Mediterranean climate works in your favor. Warm, dry summers and cool, wet winters mean a Maywood ADU rarely needs complex HVAC design, but the occasional heavy rain season makes insulation and moisture control in older walls worth doing right. Retrofitting a 1930s garage into living space without addressing moisture is a mistake that shows up later in the drywall. We treat older framing as a structural question first, not a cosmetic one. Ben Ortega, who leads our Maywood projects, reviews every structural evaluation before we price the job.
Our Main Maywood Services
Maywood homeowners call us most about these three projects. Each has its own dedicated page with pricing, process, and local details.
Home Addition Contractor in Maywood
On Maywood’s small lots, a home addition usually means going up, not out. Second-story additions over existing single-story bungalows preserve what little yard space remains while adding the bedrooms or living area a growing family needs. The work requires careful structural review of the original framing, and because many Maywood homes are wood-frame from the mid-century era, we inspect for settling and termite history before finalizing any plan. Every addition receives a written price before crews arrive, and the 365-Day Done Right Promise covers the finished work. Home Addition Contractor in Maywood.
Garage Conversion Contractor in Maywood
Attached garage conversions are the most common ADU path in Maywood because they don’t consume lot area that isn’t already built on. The catch is that many original garages in this city were built as uninsulated, unconditioned space with older slab foundations. Converting one correctly means leveling the slab, sealing it against moisture, adding insulation, and upgrading the electrical panel if the home still runs on an older service. We handle the full conversion, from permit drawings to final paint. Garage Conversion Contractor in Maywood.
ADU Builders in Maywood
A detached ADU on a Maywood lot needs a design that respects the setbacks and the neighbors. Where a standard prefab unit won’t fit, we work with brands like Abodu, Cover, and Dvele to select or adapt a compact model that clears the required distances while still delivering a full kitchen, bathroom, and comfortable living space. If a prefab design can’t work on your lot, we plan a site-built unit with the same clear pricing and the same written guarantee. ADU Builders in Maywood.
