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.
