With an increasing demand for housing in the Bay Area and homeowners need for creative second-incomes. Often times, ADUs create options for middle-income renters who don’t qualify for below-market-rate housing and can’t afford a market-rate apartment. But ADUs can be even more diverse than just a rental unit. Although ADU’s are both ‘adaptive reuse’ and ‘urban infill’, ADU’s are also highly important to our work aside from broader categories of interest. ADU’s satisfy our social mission interests by empowering home owners to become ‘mini-developers’ to create income streams on their current properties while also adding much-needed housing to the cities current fabric (with little development cost to the city and associated infrastructure).
We assist owners by wearing our architect, contractor, and developer ‘hat’ with ADU’s to help create small pro forma’s and financial docs as design-tools to understand the budget and payoff projections for their project. By assisting with financial projections, in addition to architecture and construction budgeting not only can we create a sound financial investment for our clients, but a less-conflicted process of design and construction that deals with contingencies’ in design rather than during the construction process.
With ADU code in metamorphosis in majority of cities around the US, DDB keeps up-to-date to create solutions for every site that fits the needs of an individual client. See new California Prop. http://www.hcd.ca.gov/policy-research/docs/2016-12-12-ADU-TA-Memo.docx.pdf to incentivize more ADU construction in CA.
- Rental ADUs
- In-law units
- AirBnB Rentals
- Downsizing/Retirement ADUs
- Sustainable design
- Existing building footprint design/”grandfathering”
- Detached ADUs
- ADU code facilitation
A stock answer for any size project is “It depends.” Although ADUs are small in size, their scope can be about equal to a typical new build project. Generally speaking, the ADUs we design and build (particularly the stand-alone variety) start at a couple hundred thousand dollars in construction cost, cost typically range between 250-400 per SQ FT for finishes, fixtures, and building components.
- Research your property, home history, zoning, and historic neighborhood designations.
- Look up your local jurisdiction’s ADU code. If they do not have official city code, read your state’s ADU code. (California’s ADU code)
