My experience with Housable was exceptional. The team was extremely helpful and responsive. I am very satisfied and happy to have used these services. As a homeowner I do not know the construction lingo or process but the Housable team very kind and helpful and patient with me. My expectations were exceeded. Thank you for everything.

* Delivery times are estimated based on past projects and standard drafting processes which are subject to change.

** All Standard Projects receive our permit guarantee which means that we back our services with full support for each project until the standard project reaches approval. Our team will work with you and the city to reach approval for your project as we do for all Standard Projects, but due to the complexity of Non-Standard Projects, we are not able to predict approval timeline or aspects of the project which may require revisions by the city to reach approval. For these reasons, we are unable to provide the same permit guarantee that we do for Standard Projects.

*** Total price for a Standard Project includes structural engineering fees. Base price for a Non-Standard Project does not include structural engineering fees. Structural engineering fees for Non-Standard Projects are billed as add-on fees.
