Washington DC is not a greenfield subdivision market — new construction means rowhouse pop-ups, rear infill on alley lots, English basement legalization, ADU additions, and adaptive reuse of underbuilt structures. New construction loans in Washington DC require lenders who understand DOB plan review, Historic Preservation (HP) districts, TOPA on occupied acquisitions, and recordation tax above 2%.

What gets built (and funded) in DC in 2026
| Project type | Typical cost band | Hold |
|---|---|---|
| Rowhouse pop-up (3rd floor addition) | $180K–$320K vertical | 10–14 months |
| Rear ADU / coach house | $150K–$280K | 8–12 months |
| English basement legalization | $50K–$95K | 6–10 months |
| Ground-up rowhouse infill (rare) | $600K–$900K+ | 14–20 months |
| Office-to-residential conversion (small) | $200K–$500K/unit | 18–36 months |
The office-to-residential wave — led by projects like The Geneva on Connecticut Avenue — creates spillover demand for small investors in adjacent corridors. See DC office-to-residential guide.

DOB and HP — permit reality
DC Department of Buildings plan review runs 3–6 months on rowhouse additions — longer than suburban municipalities. Historic Preservation review in Capitol Hill, Georgetown, and Dupont adds 2–4 months and constrains facade materials.
Draw schedule aligns to:
- Excavation / foundation sign-off
- Structural / framing
- Rough mechanicals and electrical
- Insulation / drywall
- Certificate of occupancy
Occupied rowhouse acquisitions may trigger TOPA — extend construction loan term to 18–24 months when tenants inherit. See TOPA compliance guide.
ADU ordinance — expanded pathways
DC’s Accessory Dwelling Unit rules allow rear structures and basement conversions on many residential lots. Investors use construction or bridge capital to:
- Build rear coach house with separate entrance
- Legalize English basement with egress and separate meter
- Pop-back addition on alley-facing lots
Post-CO exit: DSCR loans Washington DC on two-unit rent roll — often the highest-velocity BRRRR path in the District.
Worked scenario: Petworth pop-up + basement
Property: 1925 rowhouse, vacant at acquisition Acquisition: $625,000 Scope: Third-floor pop-up ($185K) + English basement legalization ($72K) Total vertical: $257,000 Construction loan (100% LTC on qualified file): $882,000 @ 10.75% IO Timeline: 13 months (HP review on front facade) Stabilized rent: Upper $2,950 + basement $1,775 = $4,725/mo As-completed value: $798,000 Exit: DSCR refi Petworth at 85% LTV rate-and-term (~$678,000 on $798K value)
Recordation and transfer tax
DC recordation and transfer often exceed 2% combined on acquisition and again on refi. Budget $12K–$18K friction on $700K assets before counting construction carry — flip math that works in Virginia may fail in DC after tax stack.
Office conversion — small investor angle
Institutional conversions (The Geneva, Portals campus) dominate headlines, but small investors participate via:
- Adjacent corridor acquisitions — spillover rent demand
- Partial building conversions — 4–10 unit office-to-residential
- Condo conversion of renovated rowhouses — see condo conversion financing DC
C-PACE and Housing in Downtown tax abatement primarily serve $50M+ projects — small sponsors use private construction debt at 8.99%–13.5%.
Why Jaken Finance Group for DC construction
We fund DMV metro deals daily from our Hoffman Estates headquarters — rowhouse vertical, basement legalization, and pop-up additions with draw inspectors who understand DOB sign-off sequence, not generic national checklists.
Comparison: DC vs Arlington new build
| DC rowhouse vertical | Arlington infill | |
|---|---|---|
| Permits | DOB + HP, slower | County, faster |
| TOPA | Often applies | No |
| Recordation | 2%+ | Lower |
| Rent | Higher gross | Similar net after tax |
Many sponsors build in Arlington and rehab rows in DC — we fund both.
GC selection — lender requirements
We require DC-licensed GC with DOB permit history on rowhouse vertical — not only suburban tract-home resume. Submit three Chicago references on 2–4 unit scope before draw schedule approval.
Petworth pop-up and Takoma row economics
Petworth and Takoma row additions trade $720K–$890K all-in on pop-up + basement scopes — finished 3-bed + ADU configurations achieve $4,200–$4,850/mo combined rent when basement CO and separate meters are clean. DC HP review on visible pop-ups adds 6–10 weeks — construction carry at 10.5% on $680K drawn balance costs $5,950/mo during permit hold.
Worked carry: $695K land + structure acquisition, $185K vertical addition scope, 70% LTC construction → avg $615K drawn at 10.75% for 11 months = ~$60,500 interest. Stabilized $4,650/mo gross supports DSCR Washington DC at 60% LTV on $980K appraised → DSCR ~1.06 after $1,850/mo modeled expenses.

DC new construction — HP and TOPA file gates (2026)
DC construction files fail when pop-up HP review adds 6–10 weeks unbudgeted, or recordation 2%+ is modeled once instead of on buy and refi.
- Pop-up worked: $625K acquisition + $257K vertical → $4,725/mo stabilized → DSCR at 85% LTV on $798K
