About Our Team

Why Glendale Is a Strong ADU Investment Market

Glendale is one of the most ADU-active cities in the San Fernando Valley. A combination of large single-family lots, a strong multigenerational housing culture, and rising property values has made ADUs both popular and financially rewarding for homeowners throughout the city.

Glendale's demographics and location create dual ADU demand: multigenerational families seeking units for parents or adult children, and working professionals commuting to Burbank's entertainment district and downtown LA. Both market segments create consistent, reliable demand for quality ADU space.

Permits & Zoning

ADU Permitting in Glendale

What Glendale homeowners need to know before starting an ADU project.

City of Glendale Development Services Department
ADUs in Glendale are permitted through the City of Glendale's Development Services Department. Glendale has fully aligned its municipal code with California's ADU laws and allows ADUs on most residential lots throughout the city.
Hillside Property Requirements
Glendale has a significant number of hillside lots with slope-related constraints. Hillside ADU projects may require additional geotechnical investigation and slope stability analysis. Our team regularly works on Glendale hillside properties and understands the city's specific submittal requirements.
Very High Fire Hazard Severity Zones (VHFHSZ)
Foothill and hillside areas of Glendale are designated VHFHSZ under CAL FIRE maps, requiring ember-resistant vents, Class A roofing, and ignition-resistant exterior materials under California Building Code Chapter 7A. We design and build to these standards and incorporate them into our scoping and fixed-price contracts.
Permit Timeline
Standard ADU permitting in Glendale takes 10–18 weeks. Hillside projects requiring geotechnical review, or properties in fire zones requiring additional state compliance review, may add time. We manage all Glendale Building Department communications throughout.

Common Questions

ADU Questions for Glendale Homeowners

Can I build an ADU on a hillside lot in Glendale?
Yes, hillside ADUs are buildable throughout Glendale, but they require additional geotechnical investigation and slope stability analysis prior to permitting. Foundation and grading work on hillside lots also adds to construction costs. We assess hillside feasibility and provide a comprehensive scope as part of your free property evaluation.
Does my Glendale property require fire-resistant construction?
If your property sits in a Very High Fire Hazard Severity Zone - common in Glendale's foothill areas - California's Title 24 and local codes require fire-resistant construction measures, including ember-resistant vents, Class A roofing, and ignition-resistant cladding. We scope and price these requirements upfront so there are no surprise costs mid-project.
How long does ADU permitting take in Glendale?
Standard ADU permitting in Glendale takes 10–18 weeks from a complete plan submission. Hillside projects requiring geotechnical review, or properties in fire zones, may take longer. Our team manages all city communications and tracks every deadline to keep your project on schedule.
What's the best ADU type for a Glendale property?
It depends on your specific lot. Glendale has many properties with detached garages - making garage conversion a fast, cost-effective first choice. For larger flat lots in central Glendale, a new detached ADU maximizes rental income. For hillside properties, we design for the site's specific constraints while maximizing livable space and views. We recommend the right option after a free site visit.
