What does Hausable provide for your ADU Permit Set?

Before starting the ADU design and drafting process to submit for permit, it is critical that all of the zoning information, site layouts and general design be sorted out. This is what we provide in our ADU Services process and for this reason, we must stick to our process to provide our services at the rates and in the timelines that we do.

The types of ADU projects we serve:

We provide services for just about any type of ADU project, though the offerings for different project types do vary.

  • New Construction Attached or Detached ADUs (1-2 stories)
  • Conversion Attached or Detached ADUs (1-2 stories)
  • Modular or Panelized Construction Methods (When product specification, engineering and details will be provided by the manufacturer.)
  • We provide services for minor-moderate remodeling of a primary home only when in conjunction with an ADU conversion or new construction project.
  • What we provide:

    Our aim is to provide a reliable and cost-effective service that homeowners as well as professionals can use to complete their ADU projects faster, and for less upfront cost and commitment than the traditional architectural process. In order to do this well, we do not provide the same level of customization and detailed project assistance that an architect does. For this reason our ADU Permit Set service may not be the best fit for every ADU project. Do your research on the costs of hiring an architect and compare them with the costs of our service to make an educated assessment of the best fit for your needs and your budget.

  • Fast & predictable timelines
  • Efficient & build-able ADU design solutions
  • Design flexibility & customizability
  • Low fixed price quotes
  • We have a defined process that allows us to guarantee the price
  • Standard construction methods
  • Somewhat of a DIY service
  • We advise on the code, not the aesthetics
  • Prerequisites for ordering your ADU Permit Set:

    In-order to provide the fast and cost effective services we do your ADU projects, we must sick with our standard process, which includes project evaluation, zoning analysis, and preliminary design. This helps us ensure that we will be able to deliver on the needs and requirements for your specific project, before getting into the details of drafting all of the design documents your city and your contractor will need to approve and build your ADU.

  • We must have completed an ADU Property and Design Report. *
  • Our team must have evaluated your design and provided a price quote for your ADU Permit Set. **
  • Our ADU Permit Set service may not be available for all project styles, customized designs, or geographic areas. ***
  • Our ADU Permit Set Drafting Process:

    We have phases that allow us to provide high quality, accurate and customized blueprint sets for your ADU project. It is helpful when using our services if you understand our typical workflow. This will help us to move your project forward quickly and with as little back and fourth as possible.

  • We take the drafted concept that you choose from our ADU Design Report concepts and begin to draft the project into preliminary construction documents
  • We typically next visit the property to take measurements and verify other relevant on site conditions
  • After visiting with you and evaluating your site, we finalize the general layout and details
  • At the end of each phase we show you the progress and seek your feedback
  • During the process you will be able to ask questions and request updates
  • We need your timely input as some changes will require more updates if made later in the process
  • Our Standard Plans Spec:

    The list below indicates the typical sheets that we draft for your ADU project in order to submit them to the city and to source estimates from contractors for your project.

  • Permitting Process:

    We provide services that prepare your project for submitting for a permit and to get bids from contractors, but our services do not end once you've submitted. We address comments and revisions that returned from the planning and building departments as a part of our service. See the list below for more detail about how it works.

  • The plans will be submitted by you or your contractor
  • All comments, requests for information and revisions returned from the planning office will be updated by our drafting team
  • During the permitting process, if you request design changes, this will require additional fees and may trigger updates to Title 24 and other compliance documents
  • If custom engineering or details are required by the planning office, we can provide engineer stamps and calculations for reasonable additional fees
  • Any special reviews, surveys or reports outside of the Standard Plans Spec provided above will be outside our scope, though we can help source these services when necessary


  • Notes:

    * We need to have the information that we gather from your ADU Property Report and site plans and ADU concepts that we create during your ADU Design Report in order to verify that we can provide you with our ADU Permit Set service and to provide you a complete price quote for the service.

    ** Once our team has opened up your ADU Permit Set and provided a final quotation for this service, you will be able to confirm your order to move forward with this next phase.

    *** Our offering to provide ADU Permit Sets is limited mostly by the desired scope of the project from the customer and in some rare cases by the requirements at the local planning office. In some rare cases we will not be able to offer the ADU Permit Set service, in which case we will notify you and we will advise of possible alternative next steps for your project.

    **** Please feel free to ask questions about the materials that we specify as a standard in our plans. Most specifications are open to change, but you must know what you would like to change them for and ideally there is a good reason for that change. We will not be able to entertain full design consultations as we do not charge appropriately for this type of service.
