What are the height restrictions for ADUs in Glendale?

Hello,

Building an Accessory Dwelling Unit (ADU) in Glendale is an exciting venture, and I’m glad to offer some clarity on the height restrictions and related regulations. Understanding these factors will help you navigate the planning process smoothly and ensure compliance with local ordinances.

### 1. Height Restrictions Based on Zoning

In Glendale, the height restrictions for ADUs vary depending on the zoning of your property. Here's a general breakdown:

- **Single-Family Residential Zones (R1, R1R, etc.):** Typically, the maximum height for a detached ADU is 16 feet. This allows for a single-story structure with a potential loft space if desired.
- **Multi-Family Residential Zones (R-2, R-3, etc.):** In these zones, you can often go up to 25 feet, which accommodates a two-story ADU. This is particularly beneficial if you're aiming to maximize the use of space on your lot.

To find the exact zoning of your property, you can check with the Glendale Planning Department or use the city's online zoning map.

### 2. Considerations for a Two-Story ADU

If you're contemplating a two-story ADU, here are some additional regulations to consider:

- **Privacy and Design:** Glendale requires that two-story ADUs are designed to minimize privacy impacts on neighboring properties. This might involve strategic placement of windows and balconies.
- **Setbacks:** The city generally requires a minimum setback of four feet from the rear and side property lines for ADUs. However, setbacks can influence your design, especially if you're maximizing vertical space.
- **Fire Safety:** A two-story ADU may need to meet additional fire safety standards, such as specific egress requirements or fire-resistant materials.

### 3. Special Permits and Exceptions

While the standard height limit is 16 feet for a single-story and 25 feet for multi-family zones, there are possible pathways for exceptions:

- **Variance Requests:** If your design necessitates exceeding these height limits, you might apply for a variance. This process involves demonstrating that the variance is necessary for the reasonable use of your property and that it won't negatively impact the neighborhood.
- **State Laws (e.g., SB-9):** Recent California laws, like SB-9, facilitate the creation of additional housing units. While primarily aimed at housing production, these laws sometimes offer flexibility in development standards, including height restrictions.

### 4. Intersections with Setbacks and Other Design Limitations

The interplay between height restrictions and setbacks is crucial:

- **Setbacks:** Beyond the standard four-foot setback, if your ADU is taller, consider shadow and privacy impacts on adjacent properties. Designs that respect these aspects often ease the planning approval process.
- **Lot Coverage:** Keep in mind the overall lot coverage limitations, which, in Glendale, typically restrict building footprints to a certain percentage of your lot size.

### 5. Cost and Timeline Considerations

For a 750 sq. ft. ADU within a $150,000 budget, you'll need to be strategic:

- **Construction Costs:** In Glendale, construction costs for ADUs typically range from $200 to $350 per square foot. This means a 750 sq. ft. unit could cost between $150,000 and $262,500. Opting for a simpler design and finishes can help manage costs.
- **Timeline:** From design to approval and construction, anticipate a timeline of 12 to 18 months. The planning approval process alone can take 3 to 6 months, depending on the complexity of your project and the city’s current workload.

### 6. Recommendations and Next Steps

- **Consult with Professionals:** Engage an architect or ADU specialist familiar with Glendale's regulations. They can offer tailored advice, streamline the design process, and help navigate permit applications.
- **Visit the Glendale Planning Department:** Consulting with city planners early can provide valuable insights and help preempt potential issues.
- **Review State and Local Laws:** Familiarize yourself with key regulations such as AB-68, which supports ADU development by reducing barriers like parking requirements and streamlining approvals.

### 7. Common Pitfalls to Avoid

- **Overlooking Design Requirements:** Ensure your design meets all local guidelines, particularly regarding privacy and neighborhood character.
- **Underestimating Costs:** Factor in all possible expenses, including permits, utility hookups, and landscaping.

By considering these elements and seeking professional guidance, you can enhance the feasibility and success of your ADU project. I wish you the best of luck with your build in Glendale!
