What is the difference between an ADU and a guest house?

An ADU and a guest house might seem similar, but they have different purposes. An ADU is a separate living unit with its own kitchen, bathroom, and living space. It is designed to be a fully functional home. On the other hand, a guest house is typically used for short-term stays and may not include all the amenities of a full home. In Hillsborough, ADUs must meet specific building codes and zoning regulations, while guest houses may have different requirements.

Yes, there are size limitations for ADUs in Hillsborough. These limitations are set by local zoning laws and building codes. Typically, the size of an ADU cannot exceed a certain percentage of the main house or a specific square footage. It’s important to check with local authorities to understand the exact size restrictions for your property. Ensuring that your ADU complies with these regulations is crucial for obtaining the necessary permits.

Yes, ADUs can be built on properties with existing structures, but there are some considerations to keep in mind. The location of the ADU must comply with local zoning laws, and the property must have sufficient space to accommodate the new unit. Additionally, the existing structures and the ADU must meet building codes and safety standards. In Hillsborough, working with experienced builders can help ensure that the ADU is integrated seamlessly with the existing property.

Yes, ADUs can be customized to match the main house in terms of design and aesthetics. Homeowners can choose materials, colors, and architectural styles that complement the main house. In Hillsborough, this can help maintain the overall look and feel of the property. Customization options include matching rooflines, exterior finishes, and landscaping. This ensures that the ADU blends seamlessly with the main house and enhances the property’s overall appeal
