Unlock Hidden Value in Your Backyard – Build an ADU in DC∙MD∙VA

Favorable zoning laws:
- DMV area has shown clear support for ADU construction by introducing favorable zoning for DC neighborhoods, zoned R3.
- As of November, 2025, Dept of Zoning has a motion on the docket to increase the maximum allotted size from 900sqft to 1200sqft. The Board is expected to vote on it in 2025.
Additional rental income: In the Washington metro area, well-designed ADUs can generate $2000-$5000 a month depending on location, size and type of rental (STR or LTR)
Property value uplift: Research shows homes in our region with permitted ADUs have seen value increases of 30%–45%.
Multigenerational living / aging in place: Provide private in-law suites, guest quarters, or future rental fallback.
Long-term sustainability: Modular rectangular or custom builds (our specialty) are solar-ready, reducing utility costs and adding modern appeal.

Based on recent local projects:

Detached 700-900 sq ft ADU in DC: ~$250-350K total cost (design + permit + build) before solar premium.
With projected rent of $2,500 – $5000/month, your gross annual income $30K – $60k = ~10-20% cash-on-cost.
If your base property value was $700K, a 30% increase from the ADU adds ~$210K.
We provide a custom financial model at no cost to each customer.

Building an ADU in DC/MD/VA comes with regulatory and site-specific hurdles:

Zoning/Permitting complexity – We handle references, submission strategy, and subs that move fast.
Utility tie-ins & alley access – We review your lot early and design around constraints.
Construction timeline and cost-overruns – Our developer mindset ensures we track schedule, avoid idle time, use modular strategies.

“How much time does permitting take in DC?”
- Depending on complexity of the build but for a full scale ADU, it is typically between 1-2 months

“Can I rent the ADU short term (Airbnb/VRBO or Long Term Rentals)?”
- Yes. Although check with your neighborhood association for any rules against STR, renting/additional income is actually one of the primary reasons why homeowners choose to build an ADU

“What’s the minimum lot size or alley access required?”
- Every lot and scenario is slightly different. Reach out to us for an evaluation

“Do you work with pre-approved modular/container systems or do you build onsite from scratch?”
- Our preference has been to build onsite. Not many know but container homes are not cheaper than a stick home and are often much less flexible in customization
“What happens if my main house is owner-occupied/parking rules?”
- Our first ADU had an owner-occupied main house who wanted a space for his family to stay during holidays and rent it when they weren’t visiting. He provided a parking pad in his rear yard. However, DC recently implemented electronic visitor parking passes that are simple to get for a short period when parking on the street.
