Why Glendale Property Owners Are Building ADUs Now
Glendale is a majority-renter city, with roughly 66% of its approximately 73,000 households occupied by renters. For the roughly 34% of households that own their home, that renter demand makes a strong case for adding an accessory dwelling unit. A detached ADU or junior ADU gives a Glendale homeowner a rentable unit, a space for extended family, or a dedicated home office without leaving the property. California's ADU legislation has made it far easier to move forward, and Hollywood Contractor Corp handles the full scope: site assessment, architectural plans, City of Glendale permit coordination, construction, and final inspection sign-off. Whether your lot is in Rossmoyne, Adams Hill, or Northwest Glendale, the process starts with understanding what your specific parcel allows.
- ✓Detached ADU construction on qualifying Glendale lots
- ✓Junior ADU conversions from an attached garage or interior space
- ✓Attached ADU additions to the primary residence
- ✓Site and setback review before any plans are drawn
- ✓Permit applications filed with the City of Glendale's building department
- ✓Full build from foundation through finished interior

Flat Lots, Canyon Slopes, and What Each Requires
Glendale's geography is genuinely varied. The neighborhoods closest to the Verdugo Mountains, including Chevy Chase Canyon, Glenoaks Canyon, and Verdugo Woodlands, sit on sloped terrain where grading, retaining walls, and engineered foundations are part of nearly every ADU or addition project. Flat-lot neighborhoods like Tropico, Grandview, and Downtown Glendale present a different set of considerations: older slab or raised foundations that may need assessment before a new structure is attached or placed nearby. Hollywood Contractor Corp scopes both terrain types honestly. On a hillside lot, we account for slope, drainage, and soil conditions before finalizing a plan. On a flat parcel, we evaluate the existing structure and utilities so the addition integrates cleanly. The goal in either case is a finished product that reads as intentional, not tacked on.
- ✓Grading and retaining wall work for canyon-area ADU sites
- ✓Foundation assessment on early-20th-century and mid-century flat-lot homes
- ✓Utility connections planned for detached ADU structures
- ✓Drainage solutions specific to sloped Glendale parcels
- ✓Structural tie-in for attached additions on older homes
- ✓Site-specific engineering coordination where required
Why Homeowners Choose Hollywood Contractor Corp
A family-run team that treats every Glendale home like it is our own.

Home Additions for Glendale's Established Neighborhoods
Not every project calls for a separate ADU structure. In established neighborhoods like Rossmoyne and Adams Hill, where many homes date from the 1920s through the 1950s, a room addition is often the more practical path. A primary bedroom suite, an expanded kitchen, a dedicated office, or a family room addition can transform how a home functions without the separate utility hookups and setback requirements that a detached ADU involves. Hollywood Contractor Corp approaches additions the same way it approaches any construction project: scope the existing structure first, confirm what the City of Glendale's planning and building departments will require, then build to match the home's existing character. Glendale's median age of 41 reflects a community of established households, and the additions we build are designed to serve those households for decades.
- ✓Primary suite and bedroom additions on existing footprints
- ✓Kitchen and living area expansions for mid-century homes
- ✓Second-story additions where lot coverage limits apply
- ✓Exterior finish matched to existing stucco or siding
- ✓Permit drawings and submittals through the City of Glendale
- ✓Interior finish work included through project completion

How the City of Glendale Handles ADU and Addition Permits
Glendale is an incorporated city with its own building and planning department, separate from Los Angeles County. That means ADU and addition permits are reviewed, issued, and inspected entirely through the City of Glendale, not through any county or state office. Hollywood Contractor Corp prepares and submits all required documentation, coordinates with the city's plan check reviewers, and schedules inspections at each required phase of construction. For ADU projects, Glendale's process includes zoning review for setbacks and lot coverage, plan check for structural and energy compliance, and a series of framing, rough mechanical, and final inspections. We manage that timeline so the project moves without unnecessary delays. Property owners in areas like Grandview, Tropico, and Adams Hill can expect a process that is methodical but navigable when the paperwork is handled correctly from the start. Call (818) 264-1955 to talk through what your specific project will require.

ADU or Room Addition: Picking the Right Approach for Your Glendale Property
The choice between a detached ADU, a junior ADU, and a conventional room addition depends on your lot, your goals, and your budget range. A detached ADU gives you the most flexibility: a fully independent unit with its own entrance, kitchen, and bathroom, usable as a rental or a private guest space. A junior ADU, carved from an attached garage or a portion of the primary home, involves less new construction but still creates a separate, permitted living space. A room addition expands the primary home's square footage without creating a separate unit, which is often the right answer when the goal is more living space rather than a rentable or independent structure. Hollywood Contractor Corp helps Glendale property owners work through that decision with a clear-eyed look at what each option involves on their specific lot. Whether your property is in the hillside communities near the Verdugo Woodlands or on a flat parcel in Northwest Glendale, the right answer starts with an honest conversation about what the site allows and what the project will actually take. Call (818) 264-1955 to get started.
- ✓Detached ADU: fully independent unit with its own entrance, kitchen and bath
- ✓Junior ADU: permitted conversion of an attached garage or interior space
- ✓Attached ADU: addition connected to the primary structure
- ✓Room addition: expanded square footage within the primary home
- ✓Lot coverage and setback review to confirm which options apply
- ✓Honest scope and timeline discussion before any commitment
