What are the zoning laws for ADUs in Anaheim?

Hello there!

It’s great to see you taking the initiative to expand your property with an Accessory Dwelling Unit (ADU) in Anaheim. You’re right that California has been encouraging the construction of ADUs through several legislative measures, and Anaheim aligns closely with these state laws while also having its own specific guidelines. Let's break down your queries one by one:

### 1. Zoning Requirements in Anaheim

Anaheim generally adheres to California state laws on ADUs, such as SB-9 and AB-68, which simplify the process and reduce restrictions. Most residential zones in Anaheim, including single-family (R-1) and multi-family (R-2, R-3, etc.) zones, are eligible for ADU construction. Your lot of 7,500 square feet is ample for an ADU, as the city doesn't impose a minimum lot size requirement beyond what’s already defined for residential zoning.

#### Local Stipulations:
- **Owner Occupancy:** As of the latest updates, Anaheim doesn't require owner occupancy for either the primary residence or the ADU, aligning with state law to promote more housing options.
- **Short-term Rentals:** ADUs cannot be used for short-term rentals, meaning they must be rented for terms longer than 30 days.

### 2. Size and Height Limits

For ADUs, California law permits up to 1,200 square feet, but local ordinances may set different maximums. In Anaheim:
- **Detached ADUs:** Typically allowed up to 1,200 square feet or 50% of the size of the primary dwelling, whichever is less.
- **Attached ADUs:** Can be up to 50% of the existing primary dwelling, not exceeding 1,200 square feet.
- **Height Limits:** Generally, detached ADUs can be up to 16 feet in height. If your ADU is within half a mile of public transit, you might have more flexibility in height and size.

### 3. Setback Requirements

Anaheim conforms to state-mandated setbacks:
- **Rear and Side Setbacks:** Minimum of 4 feet.
- **Front Setback:** This typically aligns with the existing zoning for residential properties, often around 20 feet in Anaheim, but confirm with local zoning maps for specific requirements on your street.

### 4. Costs and Fees

You’ve set a budget of $150,000, which is reasonable for a standard ADU construction in Anaheim. Here are some costs to consider:
- **Permit Fees:** Expect around $5,000 to $10,000. This includes plan checks, permits, and impact fees if applicable.
- **Construction Costs:** Estimated at $150 to $250 per square foot, depending on materials and finishes. With your budget, aim for a space of about 600 to 1,000 square feet.
- **Utility Connections:** May cost an additional $5,000 to $15,000, especially if your existing infrastructure needs upgrades.

#### Hidden Costs:
- **Soil Testing and Surveys:** Can add $2,000 to $5,000.
- **Architectural Design Fees:** Approximately $5,000 to $10,000.
- **Impact Fees:** Under AB-68, these are waived for ADUs under 750 square feet but could apply otherwise.

### Practical Steps and Timeline

1. **Consultation:** Start with a consultation with an ADU specialist or architect familiar with Anaheim's regulations.
2. **Design Phase:** Work with a designer to draft plans (1-2 months).
3. **Permitting:** Submit plans for city approval (1-3 months depending on revisions).
4. **Construction:** Once permitted, construction typically takes 6-12 months.

### Tips and Warnings

- **Early Engagement:** Engage with Anaheim’s Planning and Building Division early in the process. They can provide clarity on any unique requirements or changes in local ordinances.
- **Utility Assessments:** Ensure your property’s utilities can handle the additional load. Upgrading can be costly but necessary.
- **Neighborhood Consultation:** Discuss plans with neighbors if your ADU might impact views or privacy, to avoid future disputes.

### Next Steps

- **Visit the Anaheim Planning and Building Division:** Their website and office can provide the most current details and guidance.
- **Consider Professional Help:** Look for local architects or builders with ADU experience in Anaheim to streamline the process.

I hope this helps pave a clearer path for your ADU project. Good luck, and feel free to reach out if you have more questions!
