What's Included

Special Inclusions Only for OneStop ADU Clients

ADU Feasibility Study

No charge at initial in-person consultation

Prior to our initial meeting, our team will create a basic site plan and feasibility study indicating potential size and location of an ADU on your property and approximate permit fees. This invaluable information will help you decide if building a backyard home is right for you!

Construction Drawings

Included for our 6 pre-designed plans with signed contract

OneStop ADU’s plans are already pre-designed saving you time and money. Once you select your desired pre-designed plan, our team will situate your selected ADU model on your property and create the final construction documents including architectural and structural plans as well as the required Title 24 report.

Permit Processing

Included with signed contract

OneStop ADU prepares a comprehensive application package with required forms to submit to the city. We do not charge any fees for the time spent for submittal and subsequent reviews. This includes required architectural design, structural engineering, title 24, building code review with the city, permit processing & any required revisions.


Included as specified for our 6 pre-designed plans with signed contract

As per law, all newly constructed free standing ADUs are required to have solar to satisfy the electrical needs of your new backyard home. If the primary dwelling already has solar, you are permitted to add to that capacity to satisfy the electrical needs of the new structure. You can decide to add the solar panels to your primary home to save utility costs on the main dwelling.

OneStop ADU is including required solar with our ADU pricing. Please refer to our chart which is based on requirements for Climate Zone 7, the most common in San Diego County. If a larger system is required, there will be additional costs.
