Pricing will be calculated depending on the requirements, style, location, and complexity of the design. Not all properties will be offered this option, particularly if the report determines that, for example, variances are likely to be required for project approval, or requirements for the ADU project are substantially more customized than a standard residential design.

Frequently Asked Questions

When can I use ADU Marketplace ?

ADU Marketplace is meant for projects that are fully defined so that the contractors can give you detailed bids and estimates. Anytime before then, they can only give you a "ball park", or in other words a guess. Because of that the best time to post your project to our ADU Marketplace is after you have the technical drawings (ADU Permit Set) completed. These drawings must include floor plans, a site plan, MEP plans, title 24 energy certificate, structural plans, and scope of work, so that contractors have the information they need to provide accurate prices for the project.

* What is COD?

At the time of placing your order confirmation, you will be charged 20% of your total quoted price. The remaining balance will be charged on delivery (COD) according to the following schedule:

  • ADU Permit Sets: 30% after phase 2 and 50% after phase 5.

** What does Credited Pricing mean?

Any payment you make for ADU Services will be credited towards the next steps. For example, if you already paid $250 for an ADU Design Concept, the price for ADU Permit Set will be reduced by $250. After your first order the pricing for the next steps will be updated to show your credit.

How is pricing for ADU Services calculated?

ADU Design Concepts are priced individually and you can see the prices when you browse our model library. ADU Permit Set is priced based on several factor including size, project complexity, local requirements, property characteristics.

Why is ADU Services a value in helping me start the process?

We specialize in city zoning and planning office communications, so even if you’ve already read all the requirements and been to the city planning office, we can help you make sure you've covered all the bases. That includes checking overlapping zoning requirements of the city and underlying zones, for example for density, coverage, parking, etc. Even though many homeowners and industry professionals are able to do their own zoning research, it is always helpful to get an objective third party’s opinion. We serve our customers as an expert resource, helping them gather the information they need to evaluate all options to add an ADU to a property. Our ADU Services provide the fastest and lowest cost way to take the first step on your ADU project without commitments.

How long does it take to return my report after I confirm my order?

We return ADU Design Concepts within 3 business days after your order confirmation. Permit Sets can be completed within 20 business days after your order confirmation, but that is dependent on the communication about the project details, that we need to discuss in order to complete the project.

What if I have follow up questions about the information in my report or concepts?

ADU Services is not a recurring payment, each order charges the total price shown at order confirmation.
