In this comprehensive guide, we'll cover everything you need to know about building an ADU in San Bernardino—including the benefits, the regulations, and the step-by-step process to get started.

Overview of San Bernardino City's Regulations and Guidelines for Building an ADU

San Bernardino is located in San Bernardino County, California, with a population of 209,924 over a land mass of 59.20 square miles. When it comes to ADUs, San Bernardino City is quite accommodating. The city allows for 1+ ADUs on a given property, with a square footage limit ranging from 850 to 1,000 square feet.

Number of ADUs Allowed

Under state law, each single-family home may now add at least one Accessory Dwelling Unit. Owner-occupied single-family properties may add one ADU and one Junior ADU (JADU). Multi-family properties, for every four existing residential units, may add one ADU, provided the existing units were legally established.

Property Requirements

• Square Footage: Single-family and multi-family parcels are allowed to create up to 850 square feet for a one-bedroom ADU or up to 1,000 square feet for a two-bedroom ADU, regardless of the underlying zoning standards of the property. A Junior ADU up to 500 square feet is also allowed. The minimum size of any living unit, including ADUs and Junior ADUs, is 150 square feet according to the California Residential Code (AB68).

Types of ADUs Allowed

• Attached ADU: An attached ADU is connected to your house. Also known as Addition ADUs or “bump-out ADUs,” these units can be accessed from the primary house via a connecting door but can also function independently.
• Detached ADU: A detached ADU is separate from your primary house. These units need to adhere to your property setbacks and allowable building size (both height and square footage).
• Junior ADU (JADU): Junior ADUs are smaller units, up to 500 square feet, that can be built on the same lot as a proposed or existing single-family dwelling. Recent state bills AB68 and AB881 permit both an ADU and a Junior ADU on the same lot.

Additional Regulations

• Ownership: Owner-occupancy will not be required for new ADUs built between 2020 and 2025 (SB13 Update).
• Parking: Replacement parking is not required for lots that convert an existing garage to an ADU or Junior ADU (AB68).
• Height: State standards don't specify height restrictions.
• Fire Safety: Fire sprinklers are not required if they aren't necessary for the primary residence. Alternative fire protection methods are permitted.
• Utility Connections: Local health officer approval is required if a private sewage disposal system is being used.
• Setbacks: The maximum required setback for a detached new construction ADU is no more than 4 feet from the rear and side property lines. Setbacks are not required for ADUs and Junior ADUs converted from existing legal space. Attached ADUs must comply with the underlying zone's setbacks (AB68).
• Design Review: State standards don't require additional design review.

Cost Breakdown of Building an ADU in San Bernardino City

Construction Costs

The cost of building an ADU varies depending on factors such as size, design, materials, and labor. On average, construction costs can range from $100,000 to $250,000.

Permitting and Fees

Permit fees and impact fees can vary, but ADUs with less than 750 square feet of living area are exempt from impact fees. Permit fees typically include building permits, zoning permits, and inspection fees.

Common Concerns and Misconceptions About ADUs

Impact on Property Value

One common misconception is that ADUs negatively impact property value. In reality, adding an ADU can significantly increase your property's value. A rough estimate suggests that your property value will increase by 100 times the ADU's monthly rental value. For example, if you can rent out your ADU for $1,500 per month, your property value could increase by approximately $150,000.

Neighborhood Dynamics

Some homeowners worry that ADUs will disrupt the neighborhood dynamic. However, ADUs can provide flexible housing options that benefit the community, such as affordable housing for relatives, caretakers, or renters.

Property Taxes

Building an ADU will result in a slight increase in property taxes based on the added value of the ADU. However, the base value of your property will not be reassessed. For example, if an ADU adds $100,000 in value to your property and your property tax rate is 1.1%, your property tax would increase by $1,100 ($100,000 x 1.1%).
