Terms of Service

Please read these terms and conditions to understand our general business policies and practices for providing high quality information and online services to homeowners, contractors, architects and other real estate professionals using our paid tools and services, as well as any complimentary usage. We intend for our policies, practices, alignments and the information we provide to be an objective and reliable resource for all who use our online services, and strive to uphold the highest level of satisfaction based on these standards. These terms of service shall serve as the standard agreement for any services provided through this platform.

Our Services

The general policies and practices for delivering online ADU Services and other paid services provided on this platform are listed below showing detailed terms, specification, and representations of the accuracy of all information provided in these services. All services provided by the platform are online services and while members of our team may provide assistance and answer questions about your use of our online services, any information provided should not be construed as certain or accurate without verification by licensed third party professionals and or local code enforcement offices.

ADU Property Reports

(Now a complimentry service.)

The Property Report service provides specific information gathered on behalf of the customer for a subject property from the applicable local jurisdiction and other resources assumed to be reliable by the platform. Housable is providing this information about specific properties that is furnished to users as a good faith estimate of the development potential of a property. You should not in any way base your development, investments, or other financial decisions on this information. We strongly advise you to consult with an industry professional, for example a lender, realtor, contractor or architect who is sufficiently licensed and insured in their field, and can work with you individually to confirm all requirements before moving forward with any real estate development or investment.

ADU Design Concepts

(Typically $150 to $350 per design concept.)

The Design Concepts offered in our ADU Design Studio provide a solid starting point for most ADU projects. Customization of standard models is available upon request. Project designs will be customized to the general requests of the customer, applicable codes, and the attributes of the property to show a conceptual use of space, site layouts, existing structures and the proposed construction or conversion project. Customers may provide example layouts, photos, drawings or other materials which may help guide platform drafters in their design process for the order. Once the initial design concepts are completed, they will be returned to the customer via email within 3 business days from order confirmation and will be immediately available for viewing and download. A follow up design call will be scheduled to review the designs provided, answer questions and take reasonable requests of updates to the designs provided in order to accommodate an iterative process and help the customer visualize their project at a high level. The objective of these iterations will be to narrow down options and define the proposed project to a point where it can be reasonably estimated for cost of construction. While the platform strives to serve all customer requests for design updates, platform drafters will reserve the right to reject requests for design updates when, for example, such requests may be overly difficult to provide, updates may make the project unfeasible, or if customer requests become unreasonably frequent or unclear. Timelines to deliver updates to completed design reports will be provided on a case by case basis, though our drafters will strive to meet timelines provided. Typical updates require 2-3 business days following a customer's request.

Contractor Site Visits

(Now a complimentry service with any design concept order.)

Note that it is typical for Housable to provide introductions to third party contractors to provide on-site consultations and cost estimates for ADU projects. These site visits should be coordinated and scheduled directly between the property owner and the contractor. The visit should typically take between 1-2 hours and may include on site photos, measurements and evaluation of the site conditions which the contractor deems necessary.

ADU Permit Sets

(Typically $1,900 to $3,900 per project.)

The ADU Permit Set service provides customers with a flexible drafting service that aims to deliver construction documents required for project permitting and construction within predictable timelines and at rates agreed to prior to drafting work being initiated. Upon finalization of a project design which is desired by the customer to be drafted into a Permit Set, platform drafters will review the project for complete quotation of services. It should be noted that not all projects will be offered Permit Set services for drafting of project blueprints. Additionally Permit Sets are not made available to customers for order until after a design report has been completed and reviewed by the platform drafting team. Permit Sets will be delivered electronically via email to customers within 10-20 business days from date of order confirmation.

ADU Permit Sets follow the drafting phase schedule shown above and will be charged in three installments, 20%, 30% and 50% upon final preparation for submission. All payments are processed using Stripe's secure checkout system which accepts all major credit and debit cards. Pricing for services is quoted based on local property attributes, market values, zoning restrictions for ADUs and other local factors. Price quotations for ADU Services are made individually for each property and may be changed for future orders you place.

    Specific pricing for revisions, change orders, specical project types:

  • (a.) Revisions: Revisions requested by customers or contractors to project plans as well as requests for information (RFIs) after permit approval will be billable at reasonable rates from $45/hour to $65/hour work depending on the scope of change. In addition, change of scope which is material to a project after order confirmation may result in price changes for the project. This charge is in addition to the base price for Premium ADU Projects.
  • (b.) Project Types: Permit Set drafting services will remain fixed price for single story detached and conversion ADU projects which are compliant with state laws. Pricing for two story ADU projects which may have a discretionary review process or other increased compliance measures which will be billed on a base plus add-on pricing model.

  • (d.) Multi-Family ADU Projects: Projects on multi-family properties will be quoted on a base plus add-on pricing model and rates will vary on a case by case basis.
  • (e.) Special Reviews: Non-standard review processes such as soils reports, flood elevation surveys, boundary surveys, historical reviews, permit record requests, tree preservation reviews, environmental preservation reviews, or other similar processes are outside of the scope of our standard Permit Set services. Housable may offer assistance in sourcing third party services to meet such requests through our network of providers.
  • (f.) Additional Licensing: Services requiring special licensing or when it is requested will incur additional fees added to the base price quoted for projects. While these add-ons are uncommon for most projects, your Housable quotation will specify if a licensed engineer or architect will be required for permitting and approval of your project. When such a case is likely, additional reasonable fees will apply.

  • ADU Marketplace

    Customers may also elect to post their project to the Housable ADU Marketplace. Housable will work to connect homeowners to qualified contractors in their area. Qualified denotes that a contractor is licensed B (general) contractor with the California Department of Consumer Affairs Contractor State License Board (CSLB) or other similar state body in other states where Housable may conduct business. Additionally, Housable verifies that the contractor is bonded and insured, and performs a review of online reviews and other sources to verify that the contractor has not conducted any behavior which Housable deems to be unethical or is illegal. When possible, Housable will also review any outstanding litigation against a contractor as grounds to exclude them from the Marketplace.

    Housable will connect the homeowner with several contractors to bid on their project, but Housable does not select contractors on behalf of its customers. It is therefore the responsibility of the homeowner to properly vet a contractor prior to selecting them to begin construction. Housable may provide information such as a bid analysis report to summarize information contained within bids received from multiple contractors. This report and other communication regarding bids is for informational purposes only and does not constitute an endorsement of a particular contractor for a project. The homeowner is responsible for final vetting and selection of the contractor, and any disputes during or after construction shall be resolved between Homeowner and Contractor directly as stipulated in any bid or contract signed between those two parties. Housable does not bear liability for any construction disputes between Homeowner and Contractor.

    Software Services

    As design technology, GIS, public property information, and housing laws have advanced in recent years, it has become possible to evaluate, design, specify and permit smaller residential dwelling projects, such as ADUs, in more efficient ways that save customers time and labor costs, without sacrificing customization. The platform with its operators, and its drafters use extensive property analytics and software services to process orders for ADU Services - including architectural design systems, local zoning and permitting information, county level property information, and other internally developed software systems. Please note that our software services for ADU design, permitting and information provided in reports, design or drafting services and/or phone consultations about the information provided should not be used as the basis to make any development or investment decision.
