Property Requirements

Properties in Belmont must meet specific zoning and building standards to accommodate ADUs. These regulations are put in place to ensure safety, functionality, and harmony within Belmont’s residential neighborhoods. Understanding these requirements is the first step in planning your ADU project.

Building Size

ADUs in Belmont must adhere to size restrictions to ensure they fit within the character of the neighborhood and do not overwhelm the existing property. The size of your ADU can range from a minimum of 150 square feet to a maximum of 1,200 square feet, depending on the property’s zoning and existing structures. This range allows for flexibility in design while maintaining the residential scale.

• Single-Family Zoned Lots:

Single-family zoned lots in Belmont allow for the construction of one ADU per lot. This can be either an attached or detached unit, providing flexibility in how you choose to integrate the ADU with your existing home. The goal is to enhance the property while maintaining the neighborhood’s residential character.

• Duplex Family Zoned Lots:

Duplex family zoned lots can accommodate two ADUs, one for each unit of the duplex. This increases housing options and provides additional living space without significantly altering the existing duplex structure. It’s a great way to maximize the use of your property and provide additional rental income or living space for extended family.

• Multi-Family Zoned Lots:

Multi-family zoned lots support multiple ADUs, making them ideal for properties that already house multiple families. These ADUs must comply with zoning and density requirements, ensuring they fit within the overall property layout and do not create overcrowding.

• Attached ADUs:

Attached ADUs share a wall with the primary residence, creating a seamless integration between the new unit and the existing home. This type of ADU is ideal for those looking to maintain a cohesive architectural style and efficient use of space.

• Detached ADUs:

Detached ADUs are separate structures built on the same property as the primary residence. They offer privacy and additional living space without impacting the main residence. Detached ADUs can be used as guest houses, rental units, or separate living quarters for family members.

Owner-occupancy

In Belmont, either the main residence or the ADU must be owner-occupied. This requirement ensures proper property management and contributes to community stability by maintaining a sense of ownership and responsibility among residents.

Number Of Units Allowed

The number of ADUs allowed on a property in Belmont depends on the zoning designation. Typically, single-family lots can have one ADU, while multi-family properties can support multiple ADUs, subject to specific zoning rules. This regulation helps balance the need for additional housing with the preservation of neighbourhood character.

Belmont Building Height

The height of ADUs in Belmont is regulated to ensure they blend harmoniously with the surrounding neighborhood. These regulations help maintain the aesthetic consistency and prevent new structures from overshadowing existing homes.

• Single-family: For single-family lots, the height of ADUs is generally limited to 16 feet. This restriction ensures that the ADU complements the primary residence and does not dominate the landscape.
• Duplex family: On duplex family lots, ADUs may have height restrictions up to 25 feet. This allows for two-story designs if necessary, providing flexibility in architectural style while ensuring the new structure fits within the neighborhood’s scale.
• Multi-family: Multi-family ADUs can vary in height, but generally, they should align with the primary structure’s height. This consistency helps maintain the aesthetic balance and ensures that the ADUs are in harmony with the existing buildings.

Belmont Building Size

The size of ADUs in Belmont is regulated to ensure they complement the primary residence and maintain the neighborhood’s character. These regulations help create a balanced living environment that accommodates additional housing without overwhelming the area.

• Single-Family Freedom: Single-family lots typically allow ADUs up to 1,200 square feet. This size provides ample space for comfortable living quarters, whether used for rental purposes, guest accommodation, or family members.
• Duplex house: Duplex properties may have ADUs sized up to 1,000 square feet. This size strikes a balance between providing additional living space and maintaining the duplex’s existing structure and layout.
• Multi-Family Mix: Multi-family lots can support multiple ADUs, each adhering to size regulations that fit the property’s layout and zoning. This flexibility allows property owners to maximize their living space while complying with local building standards.

Fire Safety Regulations

Fire safety regulations are critical for ADUs to ensure the safety of occupants. These regulations include requirements for smoke detectors, fire extinguishers, and accessible emergency exits. Compliance with fire safety standards helps protect both the new ADU and the existing property.

Parking

Belmont requires adequate parking for ADUs to prevent street congestion and maintain neighborhood harmony. Typically, one parking space per unit is required, but this can vary based on the property’s location and zoning. Ensuring sufficient parking helps mitigate potential issues with increased vehicle traffic.

Utility Connections

ADUs need separate utility connections for water, sewer, and electricity. This ensures independent functionality and compliance with building codes. Proper utility connections are essential for the safe and efficient operation of the ADU, providing all necessary services without overburdening the existing infrastructure.

Setbacks

Setback regulations for ADUs dictate the distance from property lines, typically requiring a minimum of four feet from the side and rear property boundaries. These setbacks ensure that ADUs do not encroach on neighboring properties and maintain a respectful distance from property lines.

Zoning Regulations

Belmont’s zoning regulations ensure that ADUs complement the existing neighborhood, balancing density and residential character. Understanding these regulations is crucial for planning a compliant ADU project.

Single Family

Single-family zoning allows for one ADU per lot, ensuring the property remains primarily residential. This zoning designation helps maintain the character and scale of single-family neighborhoods while providing additional housing options.

Duplex Family

Duplex family zoning supports two ADUs, offering additional living space without overcrowding the lot. This zoning designation is ideal for properties that can accommodate more than one unit, providing flexibility for property owners.

Multi-Family

Multi-family zoning permits multiple ADUs, enhancing housing options while adhering to density and zoning requirements. This zoning designation allows for a variety of living arrangements, making it a versatile option for property owners.
