Choose your city

In California, the state legislature has enacted laws to encourage ADU development, making the permitting process more predictable for many jurisdictions. While local ordinances can add specific requirements, the statewide framework aims to reduce barriers. The typical housing stock, often single-family homes with yards, provides ample opportunity for ADUs. When considering construction, focus on how materials will perform in your specific microclimate – whether it's the coastal fog in Los Angeles County or the intense summer heat inland. This affects choices in insulation, window types, and roofing materials. To evaluate a provider, ask about their experience with California's ADU regulations and their process for navigating local planning departments. Inquire about their approach to site assessment, which will determine the feasibility and specific design considerations for your property.

Common questions

How big can an ADU be in Oregon?

This question pertains to Oregon, not California. In California, ADU size limits can vary by local ordinance, but state law generally permits ADUs up to 1,200 square feet. Specific setbacks and lot coverage rules also apply, so it's important to consult your local planning department for precise dimensions.

What are the downsides of ADUs?

Potential downsides include the initial construction cost and the impact on existing yard space. Consider how adding an ADU might affect your property's usability and aesthetics. Furthermore, understanding local zoning and permitting processes is crucial to avoid unexpected challenges during development.

What is the cheapest way to build an ADU?

The most cost-effective approach often involves utilizing a pre-designed or modular ADU plan. Simpler designs with fewer complex features tend to reduce labor and material expenses. Careful site preparation and minimizing custom modifications can also contribute to a lower overall investment.

What does ADU stand for?

ADU stands for Accessory Dwelling Unit. These are secondary housing units on a single-family residential lot. They are typically self-contained with their own kitchen, bathroom, and sleeping area, offering independent living space.

Are ADUs allowed in Arizona?

This question concerns Arizona. In California, ADUs are generally permitted statewide, though specific local regulations may apply regarding size, setbacks, and design. California has actively worked to streamline ADU development across the state.

What are the downsides of ADUs in Los Angeles?

In Los Angeles, downsides can include the impact on existing property use and the complexities of local permitting, though state laws aim to simplify this. Consider the effect on your yard and parking availability. Thorough planning with a knowledgeable provider helps mitigate these concerns.
