About Haus+ and Their ADU Services
Haus+ is a Bay Area-based company offering full-service, turnkey accessory dwelling unit (ADU) solutions for California homeowners. Their approach positions the ADU as a product rather than a custom project, aiming to simplify what is typically a complex and time-consuming building process.
Their units are designed to be intelligent, customizable, and suitable for a range of yard sizes. Haus+ handles the entire process — from design and permitting through to construction and project management — so homeowners have minimal involvement in the day-to-day logistics.
How the Process Works
Haus+ follows a structured four-step process:
- Site visit and customization: A team member visits the property to assess conditions and work with the homeowner on design preferences.
- Permitting and paperwork: Haus+ manages all permits and administrative requirements on behalf of the homeowner.
- Site preparation and installation: Construction is expedited to minimize disruption to the homeowner's daily life.
- Move in or rent out: Once complete, the unit is ready for immediate use — whether as a guest space, home office, rental unit, or in-law suite.
The company states that their pricing is all-inclusive and provided upfront, covering design, engineering, permitting, construction, and project management. This is intended to avoid the situation where customers are quoted a low initial price and later charged for add-ons like foundations and utility hookups.
In terms of timeline, Haus+ acknowledges that their hybrid construction approach typically takes 2 to 3 months longer than a fully modular ADU. They are transparent about this trade-off, noting that their method prioritizes build quality and durability over installation speed.
Construction Approach and Sustainability
Rather than using a fully prefabricated or modular system, Haus+ uses a panelized hybrid construction method that combines prefab efficiency with on-site finishing by skilled workers. Their wall and roof panels are designed to be strong and well-insulated, and the company states their units are built to last a century or more. This approach also avoids the need for expensive cranes during installation.
Haus+ is working toward a net-negative carbon footprint through the following practices:
- Responsible resource procurement
- Zero-waste manufacturing
- Net-zero design principles
- Use of safe and non-toxic materials only
- Labor practices aligned with ethical standards
In-house financing is available on all units, which the company positions as a way for homeowners to begin generating rental income while the unit pays for itself over time.
Any California homeowner with sufficient space on their property can potentially build a Haus+ unit. The company recommends a free, no-commitment site consultation to assess individual property conditions, particularly for sites with unique challenges such as steep slopes. Units can also be installed on properties without an existing home, though the permitting process in those cases is typically longer and more involved.
As a granny flat builder, detached ADU builder, and garage conversion contractor, Haus+ covers a range of ADU types suited to different property configurations and homeowner needs. Their units can serve as in-law suites, backyard cottages, or standalone rental units, offering flexibility in how the space is ultimately used.
In the San Francisco Bay Area, Haus+ states that their units can add significant value to a property and generate rental income in excess of $3,000 per month, depending on location and configuration.
