Encouraging Development of Accessory Dwelling Units

What municipalities can do

  • Publish clear regulations – they should be clear enough that homeowners can determine on their own if they will be allowed to create an accessory dwelling unit.
  • Ensure that fees are reasonable and as low as possible.
  • Make it possible for homeowners to know the cost of fees before they begin a project.
  • Ensure that regulations are consistent across properties when at all possible, and clearly document exceptions whenever they exist.
  • If additional parking is required for an accessory dwelling unit, allow it to be created in the front and side setbacks, and allow tandem parking.
  • Do not require additional parking if the home is within a reasonable distance of a transit stop (in San Anselmo it’s one mile).
  • Increase the allowed accessory dwelling unit size and lot coverage / floor area ratio.
  • Increase the height limit for accessory structures.

 

What agencies can do

  • Set reasonable connection fees based on cost and usage. The annual assessment for an accessory dwelling unit should not be equivalent to the assessment for the main home.
  • Publish a clear, easy-to-interpret fee schedule. Make it possible for homeowners to know the cost of fees before they begin a project.
  • Do not use fees from new development to fund water growth projects.
