Mini Cottage

Do you need to create a dwelling unit at your home for a family member, or do you wish you had a rental unit to generate income?  In the construction world, we call these “Accessory Dwelling Units”, or ADUs for short.  ADUs are a great idea, but making one a reality can be challenging. Should you order plans from a third party? Should you order a kit building and hire local contractors for foundation, plumbing, & electrical? Can you meet all the local building and energy codes for ADUs?

Instead of trying to figure it all out yourself, our goal is to provide a complete ADU package without the need to hire an architect or multiple contractors. We start with our classic gable design, handle the permit process for you, construct the building, use our trusted subcontractors, and manage the process from start to finish.

Service Area – During the Pilot Program, our Mini Cottages are offered only in our “local service area”. They are not available in our “extended service area” at this time.

Sizes – Our Mini Cottage is available in sizes ranging from 192 sq. ft. (12×16) up to 480 sq. ft. (20×24).

Installation – The Shed Shop will handle almost everything for the project including site prep, foundation, gas & electrical, water & sewer, plumbing, kitchen & bath, permits, and dealing with the city.  The client may have to handle things like lot surveys, deed restrictions, drainage systems, and/or other items that are not directly a part of the building.

Pricing – We offer nice but simple options to help keep costs down. There are also some do-it-yourself options such as doing your own painting & flooring.  Nevertheless, be aware the cost per sq. ft. for an ADU is usually higher than a full sized residence.  The reason is the most expensive items that make up a dwelling unit – electrical, plumbing, bath, kitchen, HVAC – are concentrated in such a small area.

Want more information?…

  1. First, fill out our online Mini Cottage Questionnaire.  We’ll look it over and respond with an initial evaluation.
  2. If an ADU looks doable, make an appointment to visit our showroom and meet with one of our Mini Cottage Consultants for an initial consultation.
  3. Determine if you want to take the next step and initiate a “Design & Cost Analysis” (see below).

Design & Cost Analysis – In order to prepare realistic quote, we do a comprehensive “Design & Cost Analysis” – cost $2,800.  The Analysis takes a few weeks and includes the following items.

  • Site visit to your property to evaluate possible building sites, site preparation needed, size and configuration possibilities, and locate existing utilities for hookups.
  • Create set of project-specific plans – Plot Plan, Elevation Drawings, and Building Plans.
  • Title 24 Report – this report tells us exactly what is required to pass energy efficiency requirements.  The report is tailored to your exact lot, size & orientation of building, and configuration of doors & windows.  The report covers framing dimensions, wall & ceiling insulation, type of HVAC and hot water heater, ventilation, door & window energy efficiency, shingle efficiency, etc.
  • Green Building Report – this report tells us what will be required to meet local and CalGreen standards.
  • Visit to your city – we will meet with your Planning & Building Dept. to confirm that the building can meet placement codes for easements, height, setbacks, and lot coverage limits.  We will also inquire about Development & Impact Fees and other items that may be required to obtain approval for a new backyard dwelling.
  • Building Quote – after obtaining all of the above information, we will be able to prepare a quote to construct your Mini Cottage.  If you decide to proceed, the $2,800 fee is applied to the cost of the project.
