Request ConsultationAttached ADUs are built onto the main residence, sharing one or more walls with it. This is a great option for homeowners who want to utilize existing space on their property.
Detached ADUs are separate structures from the main house and can be built in the backyard or as an above-garage unit. This type of ADU offers more privacy and flexibility for design options.
Junior Accessory Dwelling Units, or JADUs, are smaller units within the main house that have their own entrance, bathroom, and kitchenette and can be used as a rental space or for family members.
In San Jose, the city has specific regulations and permits in place for ADU construction. These include:
At Esperto Builders, we are well-versed in these regulations and can assist you in obtaining the necessary permits for your San Jose ADU construction project.
At Esperto Builders, we follow a carefully planned process for each ADU construction project in San Jose.
It is crucial to choose the right contractor for your San Jose ADU construction project. Here are some key factors to consider:
We connect ADUs to the main sewer and water service that serve the primary residence. We establish the connection to the sewer outside the primary residence, and the connection to the water service is accessed through the foundation into the primary residence. Our ADUs connect to existing electrical service through the main panel or a separate panel outside the main dwelling.
Probably, Yes. Before planning your ADU, we check with the San Jose ADU construction department on whether you are permitted and eligible to build a secondary unit. By and large, the city of San Jose looks at factors such as lot size and zoning laws to establish whether you can build an ADU.
Perhaps save it for garage conversion and consider it an addition for special circumstances. The city of San Jose does not allow you to convert a garage into a primary residence while located in front of the primary dwelling. You should check with us, and we will advise you accordingly to see if you might obtain a permit to construct some other form of ADU elsewhere on your property.
As you might expect, the sizes of the different types of new ADUs are regulated by local authorities and will likely differ from area to area.
Here are the standard San Jose ADU construction guidelines:
If you live on a residential lot and have the required space and access, you can build one detached ADU and one junior ADU (a unit no more than 500 square feet located within the home). Two detached ADUs are allowed on the property if you live on a multifamily lot.
The primary home will not be reassessed—ADUs do not trigger Prop 13. Your property tax will be recalculated based on a blended assessment, which will increase your annual property tax by about 1 percent of the value of the ADU.
An ADU can increase property value and, therefore, boosts the price of the primary home when it is time to sell. However, many factors affect home prices, and every case is unique.
