These small, self-contained living units located on the same lot as a primary residence can serve multiple purposes, including housing family members, generating rental income, or offering a private workspace. As homeowners in the Inland Empire explore ways to maximize their property value and utility, understanding the ins and outs of ADUs becomes essential.
In this comprehensive guide, we'll walk you through everything you need to know about building an ADU in the Inland Empire, from regulations and permits to benefits and practical tips. Whether you're considering converting your garage or building a new detached unit, this guide has you covered.
Before diving into the construction process, it's crucial to understand the regulations and permits required for building an ADU in the Inland Empire. Recent legislative changes have made it easier for homeowners to add ADUs to their properties, but there are still specific rules to follow.
Single-family properties in the Inland Empire are allowed to add ADUs, providing homeowners with an excellent opportunity to enhance their property.
ADUs on single-family properties can be established in several ways:
To build an ADU, the property must have an existing or proposed primary home.
For ADUs permitted between January 1st, 2020, and December 31st, 2024, owner-occupancy is not required.
Single-family homes are allowed one ADU per property. Additionally, if the property is owner-occupied, a Junior ADU (JADU) may also be permitted.
The maximum allowable floor area for an ADU on a single-family property is 800 square feet, with a minimum of 150 square feet. Local ordinances may permit larger sizes but may impose additional requirements.
Height limits do not apply to conversions of existing spaces.
Required parking for the ADU may not exceed one space per bedroom. The ADU is exempt from parking requirements if located within 1/2 mile walking distance of a public transit station. If a garage, carport, or covered parking structure is demolished or converted into an ADU, the off-street parking spaces do not need to be replaced.
For new construction ADUs, the minimum required setback is 4 feet from the rear and interior side property lines. Front and street side setbacks may be greater. Conversions of legally established structures are exempt from these setback requirements.
The installation of fire sprinklers is not required in an ADU if they are not required for the primary residence.
Cities or counties must review a valid permit application for an ADU within 60 days.
ADUs with less than 750 square feet of living area are exempt from impact fees.
ADUs must be rented for a term longer than 30 days.
A local agency cannot require the correction of nonconforming zoning conditions as a condition for approving a permit application for an ADU.
Multi-family properties in the Inland Empire are allowed to add ADUs according to California's Government Code Section 65852.2.(e). SB 897 has introduced changes to existing legislation, increasing the development potential of multifamily buildings.
ADUs on multi-family properties can be established through:
Properties with at least two legally established residential dwelling units are eligible to develop ADUs under multifamily standards.
The maximum allowable floor area for an ADU on a multifamily property is 800 square feet, with a minimum of 150 square feet.
Parking requirements are similar to single-family properties, with exemptions for projects within ½ mile of public transit stations and for conversions of existing parking structures.
For new ADU construction on multifamily properties, the minimum required setback is 4 feet from the rear and interior side property lines. Setback requirements do not apply when converting legally established structures into an ADU.
Fire sprinklers are not required in an ADU if the primary residence does not have them. Building an ADU does not mandate the installation of fire sprinklers in the existing multifamily dwelling.
The approval process for permits follows a ministerial procedure with a maximum review period of 60 days.
ADUs up to 750 square feet are exempt from impact fees.
ADUs must be rented for periods longer than 30 days.
Approval of an ADU permit cannot be conditioned on correcting existing nonconforming zoning conditions.
New ADUs, including conversions, are exempt from state and local Rent Stabilization Ordinances (RSO) for 15 years after the certificate of occupancy is issued, even for buildings usually subject to RSO requirements.
Homeowners considering building an ADU in Norwalk should be aware of specific local regulations:
ADUs are generally allowed on properties where residential uses are permitted, provided there is an existing or proposed single-family home or an existing multi-family building.
There are no minimum lot size restrictions, meaning any property size is eligible for an ADU.
The maximum size varies based on whether the ADU is attached or detached. For detailed information, visit Symbium Build.
Generally, ADUs can be at least one story and 16 feet in height.
Building an ADU can significantly boost your property’s value. According to recent studies, homes with ADUs tend to sell for more than comparable homes without one. Additionally, renting out your ADU can provide a steady stream of rental income, helping to offset mortgage costs or save for future financial goals.
ADUs offer flexible living solutions that can help address housing shortages and provide affordable housing options within the community. They also allow for multi-generational living, enabling families to live close to one another while maintaining privacy and independence.
Start by assessing your property's potential for an ADU. Consider factors such as available space, existing structures, and your budget. Engage with local planning authorities to understand zoning laws and any restrictions that may apply.
Work with an architect or designer experienced in ADUs to create a plan that meets your needs while adhering to local regulations. Focus on functionality, aesthetics, and how the ADU will complement your primary residence.
Obtaining the necessary permits is a critical step. This typically involves submitting detailed plans to the local planning department, undergoing inspections, and paying associated fees. Be prepared for this process to take some time, as it ensures your ADU will be safe and compliant with all regulations.
Once permits are secured, construction can begin. Hiring a reputable contractor with experience in ADU projects is essential to ensure the build goes smoothly and within budget.
Building an ADU can present challenges, such as navigating regulatory hurdles or managing construction delays. Stay proactive by maintaining open communication with your contractor and local authorities, and be prepared to adapt as needed.
Building an ADU in the Inland Empire is a fantastic way to enhance your property's value, provide additional living space, and generate rental income. With recent legislative changes making it easier than ever to add an ADU, now is the perfect time to explore your options.
Whether you're considering converting a garage or building a new detached unit, understanding the regulations and requirements is crucial. By following the guidelines outlined in this guide, you'll be well on your way to successfully building an ADU that meets your needs and complies with local regulations.
