  • Complimentary Phone Consultations

We are here to answer your questions! You’ll tell us about your home and property and what you are looking for in an accessory dwelling unit. We’ll provide a general overview of the regulations in your town, configuration options, financing options, and income opportunities.

  • Feasibility Assessments 

Generous grant funding from the Marin County Board of Supervisors and other foundations allows us to offer this service at no cost to Marin County homeowners who want to create new, long-term rental housing; for others the cost is $250. We’ll visit your home and determine all the options you have for creating private rental space. This may include spare bedrooms, a family room, undeveloped space under a deck, a garage, a detached studio, a large backyard with room for a cottage, or an option unique to your property. We’ll review the benefits and drawbacks of each opportunity and identify the next steps to move forward. For potential units in existing living space, we’ll measure the rooms, discuss layout options, and review exterior access.

  • Design and Permitting Services – $100/hour

We’ll use our small-space expertise to develop a design for your unit that optimizes the space and meets your needs. We can draw the plans you’ll need for an accessory dwelling unit or junior unit planning permit, and help you to apply for the permit. If you like, we’ll help you select materials and finishes for the project, and can even shop with you for cabinets and appliances. Low income Marin County homeowners who qualify can receive initial design services at no cost thanks to a generous grant from the Marin Community Foundation.
