An ADU is a small, self-contained residential unit located on the same lot as a primary dwelling. It can be either attached to the main house or a separate, detached structure. ADUs typically include all the amenities of a standard home, such as a kitchen, bathroom, and living area.

Why Are ADUs Gaining Popularity?

In recent years, ADUs have become a popular choice for homeowners due to their versatility and potential benefits. Whether you're looking to accommodate family members, create a rental unit, or simply add value to your property, ADUs offer a practical solution. In Loma Portal, the demand for ADUs continues to rise as more homeowners recognize their potential.

Benefits of Building an ADU in Loma Portal

Potential Income

One of the most attractive benefits of building an ADU is the opportunity to generate rental income. With the high demand for housing in Loma Portal, an ADU can provide a steady stream of additional income, helping to offset mortgage payments or other expenses.

Increased Property Value

Adding an ADU to your property can significantly increase its market value. Prospective buyers often see ADUs as a valuable addition, making your property more attractive and potentially leading to a higher selling price.

Addressing Housing Shortages

By building an ADU, you're contributing to the local community's efforts to address housing shortages. ADUs provide affordable housing options for renters, helping to alleviate the pressure on the housing market.

Zoning and Legal Considerations for Building an ADU in Loma Portal

Local Regulations and Permits

Before you start your ADU project, it's crucial to understand the zoning laws and regulations specific to Loma Portal. On single-family residential lots in San Diego, you can construct one ADU, either attached or detached, along with one Junior ADU (JADU). However, JADUs require the owner to occupy the property.

Size and Construction Guidelines

In San Diego City, the maximum living area of both attached and detached ADUs shall not exceed 1,200 square feet. Attached ADUs on top of an existing accessory structure may reach up to 21 feet or 30 feet, depending on the roof type. Detached ADUs can have a minimum height of 16 feet with reduced setbacks, while taller structures must adhere to specific height limits and setbacks.

Consistency in Exterior Features

Your ADU must maintain consistency with the exterior features of the primary dwelling, including roofing, trim, walls, windows, and color palette. This ensures a cohesive look and feel between the main house and the ADU.

Parking and Setback Requirements

For an ADU, a single parking space can be designated, which can be situated within the setback areas or integrated into an existing driveway as tandem parking. However, an ADU does not require a parking space if it meets certain criteria, such as being within a one-half mile radius of public transportation or within one block of a car-share location.

Owner Occupancy and Leasing Restrictions

While cities don't require owner occupancy until 2025, properties with both an ADU and JADU must comply with JADU laws requiring owner-occupancy of either the newly created JADU or the single-family residence. Additionally, an ADU may not be leased for a term of less than 31 consecutive days or used for transient lodging.

Breakdown of Costs

Building an ADU involves various costs, including design, permitting, construction, and finishing. It's essential to create a detailed budget to ensure you have a clear understanding of the total investment required.

The Design and Construction Process for Your ADU

Planning and Design

The first step in building an ADU is to carefully plan and design the unit. Work with an architect or designer to create a layout that maximizes space and functionality while adhering to local regulations.

Permitting

Obtaining the necessary permits is a critical part of the ADU construction process. Submit your design plans to the local planning department for approval and ensure all required permits are in place before construction begins.
