Thinking about adding an accessory dwelling unit to your Glendale property? Whether you are planning space for family, a dedicated home office, or steady long-term rental income, an ADU can add comfort and flexibility to your life. Glendale’s rules are clear and generally supportive, which helps projects move faster when you plan well. In this guide, you will learn what Glendale allows, smart ways to use an ADU, design and parking tips, costs and timelines, and practical next steps to get started. Let’s dive in.
Glendale administers ADUs through a ministerial, non-discretionary process that aligns with California law. The city’s ADU page outlines what is possible and how to get started. You can review current standards on Glendale’s official ADU guidance page for the details you will need as you plan your project. You can find that resource on the city site at the ADU information page.
A compact detached ADU or a garage conversion can create a quiet, light-filled workspace with a private entrance. Garage conversions are often the most cost-efficient path. Plan reliable high-speed internet, natural light, and storage. If you plan to operate a home-based business, confirm any home-occupation permit needs with the city. City of Glendale ADU info
A small ADU or a JADU can host relatives for extended visits while preserving privacy. Since Glendale requires rental terms longer than 30 days for ADUs, your guest use aligns with city rules. If older adults will use the space, consider zero-step entries and one-floor living for ease of movement. City of Glendale ADU info
Many families use ADUs to keep loved ones nearby while maintaining independence. Design for clear, separate entries and good visual privacy, then add accessibility touches like wider doors and an accessible shower if needed.

Across California, most ADUs are rented long-term rather than used as vacation rentals. A statewide survey reports a median ADU construction cost around $150,000 and a median rent near $2,000 per month, though final numbers vary by location and design. In Glendale, remember the 30-day minimum rental term and check any HOA rules before you start. Terner Center statewide ADU survey
Before you sketch plans, confirm where an ADU can sit on your parcel. Glendale’s planning team and Glendale Water & Power can flag easements and service lines that influence placement. The ADU cannot be between the main home and the street. Consider pre-approved plan options if they fit your lot, since they can shorten review time. City of Glendale ADU info
Aim living room and bedroom windows away from your neighbor’s main living spaces where feasible. Use porches, planter beds, and fencing to create soft visual buffers. For walls that face your main house, ask your designer about assemblies with higher sound ratings and plan quieter locations for condensers and other equipment.
If older adults or people with mobility needs may live in the ADU, prioritize no-step entries, reachable switches and controls, and a bathroom designed for accessibility. A simple, open layout with clear sightlines helps residents and caregivers. AARP accessibility guidance
Glendale’s parking rules are practical for small lots. The city caps ADU parking at one off-street space per unit or per bedroom, whichever is less. Tandem spaces are allowed, which can preserve yard area. If you are within one-half mile of a public transit stop, you do not need to provide an on-site ADU parking space. In many situations, the ADU shares the existing driveway rather than creating a new street-facing curb cut. Glendale Municipal Code
Practical strategies you can consider:
According to a statewide owner survey, the median ADU construction cost is about $150,000, with a median rent near $2,000 per month. Garage and interior conversions tend to cost less than detached new construction, while larger, 1,000 square foot backyard builds can run higher due to foundations, utilities, and site work. Treat these as ballparks and get a feasibility estimate tailored to your lot. Terner Center statewide ADU survey
California law sets ministerial review standards and a 60-day action window once an ADU application is deemed complete. Glendale implements this process and offers permit center support and pre-application options to reduce iterations. The fastest paths usually combine complete plans, early utility coordination, and the use of pre-approved plans where feasible. For an overview of state rules, see the HCD ADU Handbook.

Homeowners often use a mix of financing, such as a home equity line of credit, a construction or renovation loan, or a cash-out refinance. California’s housing finance agency has offered ADU grants to cover predevelopment costs in past rounds, but funding changes frequently. Confirm the current status before you apply. A lender experienced with ADUs can help you match financing to your timeline and budget. CalHFA ADU program
Projects submitted after January 1, 2026 must follow Glendale’s 2026 Building and Safety Code, which implements the state’s 2025 Title 24 code cycle plus local amendments. These rules can influence choices like solar readiness, EV charging readiness, and mechanical systems. Your designer will prepare the Title 24 energy documents and coordinate any new requirements. Check the city’s Building Codes page for specifics before finalizing plans. Glendale Building Codes
