Redwood Estates ADU Zoning and Building Standards

Property Requirements

The property requirements for an ADU in Redwood Estates vary depending on the zoning and lot size. Ensuring your property meets these prerequisites is the first step in your ADU project. This includes understanding setbacks, maximum lot coverage, and other critical factors that influence the feasibility and design of your ADU.

Building Size

The size of your ADU will depend on your property’s zoning classification and lot size. Understanding these limitations helps in planning an ADU that maximizes space while staying compliant. Specific size limits ensure the ADU remains an accessory structure and does not overshadow the primary residence.

  • Single-Family Zoned Lots:

For single-family zoned lots, ADUs are typically restricted to a certain percentage of the main dwelling’s size. This ensures the ADU remains a secondary structure and complements the main house. Typical size restrictions might limit the ADU to around 800 square feet or a certain percentage of the lot size, whichever is smaller.

  • Duplex Family Zoned Lots:

Duplex family zoned lots have slightly different regulations, allowing for more flexibility in the size and placement of ADUs. These lots can support multiple ADUs, enhancing the property’s value and functionality. You might be allowed to build larger ADUs or have two smaller units, providing more options for accommodating family or generating rental income.

  • Multi-Family Zoned Lots :

Multi-family zoned lots provide the greatest flexibility for ADU development. These lots can accommodate both attached and detached ADUs, providing various options for expanding living space. Multi-family zoning might allow for several ADUs on a single property, offering significant opportunities for property investment and development.

  • Attached ADUs:

These units are connected to the main dwelling, providing a seamless integration into the existing structure. Attached ADUs often share a wall with the main house, making them cost-effective and easier to build.

  • Detached ADUs:

These units stand alone, offering greater privacy and independence from the main dwelling. Detached ADUs can be built in various styles and sizes, making them a versatile option for additional living space.

Owner-occupancy

In Redwood Estates, there are specific owner-occupancy requirements for ADUs. Typically, the property owner must reside in either the main dwelling or the ADU, ensuring a vested interest in maintaining the property. This regulation helps maintain the quality and integrity of residential neighborhoods, as owner-occupied properties are often better maintained and managed.

Number Of Units Allowed

The number of ADUs allowed on a property in Redwood Estates depends on the zoning and lot size. Generally, single-family lots can have one ADU, while multi-family lots can have multiple units. This regulation helps control density and maintain the residential character of neighborhoods.

Redwood Estates Building Height

Building height restrictions ensure that ADUs do not disrupt the overall aesthetic and privacy of the neighborhood. These regulations vary depending on the zoning classification of the property.

  • Single-family: For single-family lots, the maximum height for an ADU is usually limited to ensure it remains a secondary structure. This might mean a one-story ADU with a maximum height of 16 feet.
  • Duplex family: Duplex family lots may have slightly higher height allowances, providing more design flexibility. This could include the option for a two-story ADU, with a maximum height of around 18 feet.
  • Multi-family: Multi-family lots often allow for the tallest ADUs, accommodating multi-story units if desired. These ADUs might reach up to 20 feet, providing ample space for larger living areas.

Redwood Estates Building Size

The building size of an ADU is a critical factor in planning your project.

  • Single-Family Freedom: Single-family lots have specific size limits to ensure the ADU complements the main dwelling. These limits often restrict the ADU to around 800 square feet or a certain percentage of the main house’s size.
  • Duplex house: Duplex lots offer more leeway in ADU size, supporting larger units that provide more living space. You might be able to build an ADU up to 1,000 square feet, depending on the lot size and local regulations.
  • Multi-Family Mix: Multi-family lots allow for the largest ADUs, enabling the creation of spacious and functional additional units. These ADUs can often be up to 1,200 square feet, offering significant additional living space.

Fire Safety Regulations

Fire safety is a paramount concern in ADU construction. Ensuring your ADU meets all fire safety regulations is crucial for the safety of its occupants. This includes proper installation of smoke detectors, fire-resistant building materials, and ensuring clear access for emergency vehicles.

Parking

Parking requirements for ADUs vary, but generally, additional parking spaces must be provided to accommodate the new unit. This helps ensure that the addition of an ADU does not negatively impact street parking and neighborhood traffic.

Utility Connections

Proper utility connections are essential for the functionality of your ADU. This includes water, electricity, and sewage systems. Ensuring these connections are properly installed and meet local codes is crucial for the safety and comfort of your ADU.

Setbacks

Setback regulations dictate the distance your ADU must be from property lines, ensuring it does not encroach on neighbors’ spaces. Typical setback requirements might include a minimum distance of 4 feet from side and rear property lines.

Zoning Regulations

Zoning regulations in Redwood Estates are designed to maintain the community’s character while allowing for the development of ADUs. These regulations include specific requirements for different zoning classifications.

Redwood Estates ADU Zoning Regulations

Single Family

Single-family zoning typically allows for one ADU per lot, with specific design and size restrictions. These regulations help maintain the low-density residential character of the neighborhood.

Duplex Family

Duplex family zoning provides more flexibility, allowing for multiple ADUs and larger units. This zoning classification supports higher density residential use while maintaining the residential character of the area.

Multi-Family

Multi-family zoning offers the greatest flexibility, supporting multiple ADUs and various design options. This zoning is ideal for property owners looking to maximize the use of their property and generate rental income.
