Glendale ADU Construction — Extended Family and Rental Solutions
Glendale homeowners in Glenoaks Canyon, Adams Hill, and Montecito Park are converting older garages into ADUs for extended family housing — and Caspi Construction manages the complete Glendale Building & Safety permit process from feasibility through finished construction.
Glendale's older residential neighborhoods — Glenoaks Canyon, Adams Hill, and Montecito Park — were developed with larger lots that frequently include detached garages positioned at the rear, accessible from alleys. Many of these garages date from the same era as the homes they serve, built in the 1920s through 1950s and now sitting underused while representing substantial untapped value. Glendale's Armenian-American homeowner community frequently builds ADUs with multigenerational family housing as the primary goal — a converted garage that provides private, dignified living space for parents or adult children while maintaining proximity to the main household. ADU contractor work in Glendale requires specific knowledge of Glendale Building & Safety permit requirements, which differ meaningfully from LADBS across documentation standards, inspection scheduling, and setback interpretation. Caspi Construction is a licensed Glendale ADU construction company (CSLB #1091631) with a 4.9★ rating and direct experience with Glendale's permit process.
Our Glendale ADU Construction Services
Glendale Garage Conversion ADU
Glendale garage conversions begin with a structural assessment of the existing garage and a Glendale Building & Safety pre-application review to confirm compliance with the city's setback, lot coverage, and unit size requirements. We prepare architectural drawings to Glendale's documentation standards, manage the permit application through plan check, and complete all construction work — structural, MEP, insulation, and finish work — through certificate of occupancy. Typical cost range for Glendale garage conversion ADUs: $85K–$130K.
Multigenerational ADU Design
ADUs designed for extended family members — parents, adult children, or family caregivers — are designed with specific functional priorities. We incorporate accessible features where requested: wider doorways, curbless shower entries, grab bar blocking, and single-level layouts. We also design for the social dynamics of multigenerational living: thoughtful acoustic separation, visual privacy from the main house, and outdoor connections that make the ADU feel like a home rather than an annex.
Period-Appropriate Exterior Design
Glendale's Craftsman, Spanish Colonial, and mid-century housing stock creates an expectation that ADU exteriors will complement the main house's architecture rather than clash with it. We design ADU exterior finishes — siding, roofing, window profiles, and entry doors — to be architecturally compatible with the primary residence, maintaining the visual coherence of the property while clearly identifying the ADU as a distinct and complete dwelling.
Glendale Building & Safety Permit Navigation
Glendale Building & Safety has its own plan check standards, inspection scheduling, and documentation requirements that differ from LADBS and from other city permit authorities in the area. Our team knows Glendale's process and prepares permit applications that meet the city's standards on first submission, avoiding the delays that come from incomplete documentation. All Glendale ADU design build projects end with a full certificate of occupancy.

Recent ADU Projects Near Glendale
Project 1 — Adams Hill Multigenerational Garage ADU
An Adams Hill homeowner had a detached two-car garage from the 1930s at the rear of their Craftsman bungalow lot — structurally sound, alley-accessible, and large enough for a comfortable one-bedroom unit. The homeowner's elderly parents were ready to move in from out of state, and the goal was a unit designed with their comfort and accessibility as the priority. We added wider doorways throughout, a curbless walk-in shower with grab bar blocking in the bathroom, MSI Calacatta Miraggio tile, Kohler fixtures in a coordinating brushed nickel, a full kitchen with Caesarstone White Attica quartz countertops and LIOHER cabinetry, LVP flooring throughout, and a covered porch connection to the main house backyard. Glendale Building & Safety permits were managed from pre-application through certificate of occupancy. Completed in eighteen weeks.
Project 2 — Glenoaks Canyon Garage Conversion for Rental
A Glenoaks Canyon homeowner had a detached garage on a large lot that had been unused for storage for years. With Glendale one-bedroom ADU rents running at $1,800–$2,400 per month, the economics were compelling. We designed a 460-square-foot studio ADU with an open kitchen-living area, a full bathroom with 4x12 MSI subway tile and a Kohler walk-in shower, LVP flooring, a new mini-split system, and a private entrance from the alley. The exterior was updated with stucco to match the main house. Glendale Building & Safety permits were submitted and managed through all inspections. The ADU renovation in Glendale was completed in fifteen weeks from permit approval and rented within two weeks of certificate of occupancy.
Project 3 — Montecito Park JADU for Adult Child
A Montecito Park homeowner wanted to create an independent living space for their adult child who had returned to the area — a JADU within the existing home footprint that would provide privacy and independence while keeping the family close. The home had a large bonus room on the ground floor with a direct exterior access door, which was ideal. We added a kitchenette with a two-burner induction cooktop, under-counter refrigerator, and MSI quartz counter, upgraded the adjacent bathroom with new MSI tile and Kohler fixtures, installed a mini-split for independent climate control, and replaced the exterior door with a new insulated unit with a keypad lock and video doorbell. The ADU design build in Glendale was completed in eight weeks under Glendale Building & Safety JADU permit.

Common Questions From Homeowners
All ADU construction in Glendale goes through Glendale Building & Safety — not LADBS. Glendale has its own plan check standards, documentation requirements, and inspection schedule. Caspi Construction manages the full Glendale permit process, from pre-application review through final certificate of occupancy, as part of every project.
Garage conversions are by far the most common ADU type in Glendale's older residential neighborhoods, where detached garages are frequently large enough to accommodate a comfortable one-bedroom unit. Junior ADUs within the existing home footprint are the second most common, particularly for homeowners whose properties don't have a qualifying detached structure.
Glendale garage conversion ADUs typically run $85K–$130K depending on garage size, structural condition, and finish specification. This includes all design, Glendale Building & Safety permitting, MEP systems, and finish work through certificate of occupancy.
Yes — we design accessible ADUs for Glendale homeowners who are building for elderly parents, family members with mobility considerations, or future flexibility. Accessible features include wider doorways, curbless shower entries, grab bar blocking in the bathroom, and single-level layouts. These features are incorporated during the design phase and permitted through Glendale Building & Safety.
Glendale Building & Safety permit review typically runs eight to fourteen weeks for an ADU application. Construction runs twelve to eighteen weeks for a garage conversion and eight to twelve weeks for a JADU.
