Build an Alley Flat

I want to learn more about The Alley Flat Initiative and maybe build an affordable ADU in my backyard! What are the next steps?

1. Initial Assessment and phone call:

We can do an initial assessment of your property first to see if it qualifies for an Alley Flat development based on zoning and lot size. The only thing we would need from you at this point is your address. After the initial assessment we can schedule a time to talk over the phone to share our findings and talk about next steps.

2. Site visit (1hr/$80):

After our initial phone consultation, we can meet with you on site (With masks and social distancing) to talk about how an ADU could fit in your backyard. Together we will evaluate the maximum Alley Flat size, placement options, and potential catalog models. If needed, we can have a follow-up virtual meeting with you to discuss more specifics for your ADU design and our program.

The site visit has a non-refundable fee of $80, which will be credited to your service proposal total if you wish to proceed with the project. The credit expires after 6 months. Payments should be received at least 2 hours prior to the scheduled site visit. If payment is not received, the site visit will be cancelled. Pay for your consultation here.

In preparation for the site visit, we will need:

  • your address
  • property survey
  • known restrictions for your property
3. Project proposal:

If you decide to move forward with the project, we will provide you with a full proposal for your Alley Flat, which includes estimates for structural and civil engineering as required.
