Fielding ADU Builders handles accessory dwelling units, garage conversions, and room additions across Glendale. The housing stock here runs older than most of Los Angeles County, which means foundation quirks, narrow side yards, and setback rules written decades before ADUs were common. We put the price in writing before any work starts and stand behind every job with the 365-Day Done Right Promise. Call (361) 315-4177 to talk through your project.
Why Glendale Homes Are Different
Glendale’s ADU and addition work is shaped by three things: hillside lots, aging garages, and a permit office that expects plans to match what gets built. Homes in the Verdugo Woodlands and Rossmoyne neighborhoods often sit on sloped terrain, which changes how a foundation ties into grade and where drainage has to go. Flatland neighborhoods like Adams Hill, Sparr Heights, and the streets north of Glenoaks Boulevard tend to have detached garages from the 1940s and 1950s, many of them unpermitted or built on slabs that were never engineered for living space. Summer heat in Glendale is real, so insulation and HVAC sizing get more attention here than a coastal build would. And because the city reviews ADU plans against its own accessory dwelling unit ordinance, the paperwork path is specific to Glendale, not generic LA County. We factor all of that into the written price before a single nail is driven.
Our Main Glendale Services
Two jobs dominate the calls we get from Glendale homeowners: converting a garage into livable square footage, and building a detached ADU in the backyard. Room additions run close behind, especially on the larger lots east of Brand Boulevard.
Room Addition Contractor in Glendale
A room addition in Glendale usually means extending out the back of a postwar ranch or adding a second-story bump on a hillside home. Footing depth, shear wall requirements, and roofline tie-ins all have to satisfy city inspectors, and the older the house, the more we find once walls open up. We price the job in writing before work begins, and the written guarantee covers the finished room for a full year. See how we approach Room Addition Contractor in Glendale work on its own page.
Garage Conversion Contractor in Glendale
Many Glendale garages were built as storage, not shelter. Converting one means addressing the slab, raising or reinforcing the walls, adding insulation that meets current title 24 energy rules, and often running new electrical service. Detached garages in neighborhoods like Adams Hill and Verdugo Woodlands typically need more work than attached ones. We handle the full conversion, permits included in the written quote. Details are on the Garage Conversion Contractor in Glendale page.
ADU Builders in Glendale
A detached ADU in Glendale has to respect hillside setback rules, side-yard width limits, and whatever the lot’s existing structures already claim. We work with prefab platforms like Abodu, Cover, and Dvele when the lot suits a factory-built unit, and we build conventional stick-frame ADUs with James Hardie siding when it doesn’t. Either way, the price goes in writing first and the work is covered for 365 days. The full breakdown is on the ADU Builders in Glendale page.

Brands We Service in Glendale
We finish ADUs built on Abodu, Cover, and Boxabl platforms when the shell arrives from the factory and the site work falls to us. Foundation prep, utility connections, and interior completion for those units follow the same Garrison Standard as our conventional builds. See our brands for the full list of platforms we work with.
