The simple answer is approximately 60-80 days from the purchase of one of our 5 model ADUs. It can take 2-8 weeks to get the approval and building permit from the city. Once the building permit is issued and the construction scheduled it will take 7-9 weeks to complete the build of the ADU.
There are seven phases to the process of building an ADU on your property.
- Phase 1 The preliminary site survey, planning and placement qualification. (5-10 days)
- Phase 2 Application to the city for approval and building permit. (2-6 weeks)
- Phase 3 Pre-construction site prep. (5 days)
- Phase 4 Foundation, floor and underground utility connection. (5 days)
- Phase 5 Framing and 4-way inspection. (7-10days)
- Phase 6 Sheet rock, siding, shingle and finish work. (2-3 weeks)
- Phase 7 clean up and final inspection (5 days)
For more detailed information on what is accomplished in each phase click (HERE) (the information below is the more detailed information on the build process)
Phase 1 The preliminary site survey, planning and placement qualification. A member of our team will meet with you on your property to verify that the ADU model you are planning on and your planned placement will fit on your lot and meet the buildable criteria check list which includes meeting City’s ADU ordinance guidelines for placement, and parking requirements. There will also be the review of how utilities will be connected from the ADU to your home. This is typically about a 5-7 day time frame
Phase 2 Application to the city for approval and building permit. A complete set of construction and engineering prints will need to be submitted to the building department for your intended ADU. The city will move this through its approval process. This can take from 2-8 weeks.
Phase 3 Pre-construction site prep. Blue stakes utility marking services are scheduled and your property is marked for all utilities. You as a home owner will need to mark and any items you may have underground like sprinkler lines. Our team will meet you on-site and stake our the placement of the ADU on the property as to the plans approved by the city. Our team will also mark the areas where excavation and trenching will be required for the connection of the utility lines. This is will be reviewed and signed off by the owner prior to any on-site construction.
Phase 4 Foundation, floor and underground utility connection. A construction crew will install the helical pier foundation system, trench and install all underground utility connections and close up the trenches. The ADU floor, along with the below floor plumbing and insulation will be installed.
Phase 5 Framing and 4-way inspection. Materials and construction crew will arrive to frame the house, install the exterior windows, doors and dry in the roof. The rough-in electrical, plumbing, HVAC, will be completed and the City will be scheduled for their 4-way inspection of the property prior to sheet rock, siding and finish work.
Phase 6 Sheet rock, siding, shingle and finish work. The interior of the house will be sheet rocked, mudded tapped and textured. Finish trim and molding installed prior to the interior of the house being painted. Once painted the cabinets, flooring, plumbing, electrical, lighting and HVAC systems will be installed. The exterior will have the final roofing, siding along with all exterior trim work completed
Phase 7 clean up and final inspection site will be cleaned up and a walk through inspection will be completed with the client identifying the final punch list of items to complete. Punch list will be resolved and the ADU will be complete.
