Austin ETJ Water Capacity Small Development Financing Guide

Sponsors with a capital partner already lined up still lose nine months on Austin exurban pods because the bottleneck is not rate. It is water, wastewater, ETJ jurisdiction, CCN boundaries, and MUD bond math — then construction pricing.

This guide is the diligence list a private construction desk actually uses on 4–20 door entitled pads in Manor, Elgin, Buda, Kyle, Liberty Hill, Dripping Springs, and Georgetown ETJ — not master-plan acreage with a logo and a prayer.

ETJ versus full-purpose — three utility worlds

Jurisdiction type	Who owns water/wastewater	Typical pod size	Investor friction
Austin full-purpose	Austin Water	Infill scrape, small ADU	Compatibility FAR, impact fees
City ETJ (Buda, Kyle, Manor ETJ)	City extraterritorial utility or negotiated CCN	6–20 cottage/townhome	Provider letter, not Austin Water
MUD / WCID (exurban Travis/Hays)	District operator + bond assessment	8–20 in finished plat	PID/MUD carry + dual tax bills
County / septic (Hill Country)	Onsite wastewater, well	4–8 cottage cautiously	Septic design capacity per door

Rule one: Read the provider name on the entitlement letter — not the mailing address “Austin, TX.”

CCN — Certificate of Convenience and Necessity

Texas CCN law maps which utility may legally serve a geographic area. A pad “near” a Buda subdivision does not automatically inherit that subdivision’s will-serve if CCN boundaries do not cover the parcel.

Investor diligence:

1. Pull CCN map from Texas Commission on Environmental Quality (TCEQ) utility maps or provider directly
2. Confirm water and wastewater CCN holder for exact parcel
3. Request will-serve / capacity letter for N connections (match pod count + fire flow if required)
4. Budget tap, impact, and facility fees from provider fee schedule — not broker guess

Capacity letter is a close condition on entitled pod files — vertical schedule assumes letter date before foundation draw.

MUD versus city ETJ on north and south Austin spillover

North / northeast (Manor, Elgin, Hutto spillover): Travis and Williamson county lines, mixed MUD and city ETJ utilities. Bond assessments $1,500–$4,000+/yr/door common. Collin CAD-style dual tax parcels less common than Collin but MUD bill separate from county/school still appears.

South (Buda, Kyle, Dripping Springs): Hays County appraisal, fast growth, wastewater treatment queues in boom corridors. Production builder comps abundant — pocket cottage must beat tract on rent or sell-out price.

West (Liberty Hill, Leander edge): Liberty Hill and Lago Vista paths — verify provider and school district (Liberty Hill ISD vs Leander) as comp fence, same as Carroll vs Coppell in DFW.

When septic beats central sewer (and when it does not)

4–6 cottage pod on 2–4 acres Hill Country: onsite wastewater (ETJ or county) may be only path. Design capacity must match door count — not single-home septic scaled by hope.

10–20 door pod: regional wastewater or MUD almost always required. Septic at ten doors is a red flag unless engineered cluster system with maintenance covenant — HOA must fund.

Lenders pass 10-door pro forma on five-house septic without engineer letter.

Entitlement versus vertical — community build rules recap

This guide covers entitled pads only — recorded map or approved site plan, shared drive engineered, HOA path drafted.

Stage	Product
Raw acreage, no plat	Vacant land or A&D
Entitled 4–20 pad	Community build
One spec house	Spec BTR

We do not fund 200-lot amenity master plans on this desk.

Leverage and carry on ETJ pods

Same rails as Texas construction statewide:

Parameter	Setting
Rate	8.99%–13.5% IO
Term	12–18 months
Cap	Lower of LTC and 75% LTARV
Release	Lot/unit release as COs issue
DSCR exit	5.75%–10.5%, 70%–75% LTV, 1.0+ DSCR

Tax: Hays or Travis CAD January 1 roll — model full improved value on hold doors. MUD/PID permanent.

Interest reserve: 14–18 months — ETJ civil and utility delays are common; 6-month reserve fails.

Worked example — Kyle ETJ 10-cottage BTR pod

Site: Entitled pad, Buda/Kyle ETJ, provider = city extraterritorial utility (not Austin Water). 1,380 sf rental cottages.

Line	Amount
Pad / entitlement basis	$380,000
Shared civil + utility extensions	$310,000
Vertical 10 × $198K	$1,980,000
Soft, permits, legal	$142,000
Contingency (12%)	$278,000
Total cost	$3,090,000

Capacity diligence (timeline):

Step	Weeks
CCN verification + provider meeting	2–3
Will-serve letter 10 connections	4–8
Civil bid finalized post letter	2–4
Vertical permit	3–5
Pre-vertical dead carry	8–16 weeks

Budget $45,000–$70,000 IO on land + soft during capacity queue at 10.5% on $600K average drawn.

Valuation: Pocket BTR comps $340K/door — $3.4M as-completed. 75% LTARV = $2,550,000. All-in $3.09M → LTC 82.5% would be $2,549,250. LTARV binds.

Rent exit: $2,450/mo × 10 = $24,500 gross. Expenses with Hays tax ~2.1% and MUD $2,800/yr/door → NOI tight. Need $2,650+/mo or sell 6 / hold 4.

Close condition met: Will-serve letter dated before first foundation draw. Without letter, construction facility does not fund vertical — land bridge only if exit named.

Worked example — Liberty Hill 8-cottage for-sale pod

Liberty Hill ISD, MUD district, for-sale $395K target per door.

Line	Amount
All-in	$2,680,000
As-completed 8 × $395K	$3,160,000
75% LTARV	$2,370,000
Sponsor equity gap	~$310,000 + reserve

**MUD assessment $3,200/yr/door — buyer objection on marketing (“Why is tax so high?”). Sales team must disclose PID/MUD line honestly or DOM slips.

Sell-out 2 doors/month months 10–14 — size interest reserve for slow first closing, not best-case absorption.

Draw schedule with utility gates

Draw	Gate
Land / entitlement close	Title + entitlement recorded
Shared civil	Civil inspection + capacity letter on file
Foundation batch 1–4	Utility tap proof
Framing batches	Standard milestone
CO release	Per-unit release from facility

No finish draw on unit 7 if shared lift station for pod is incomplete — CO chain breaks.

HOA, rental caps, and DSCR

BTR hold on 8–12 doors requires CC&Rs allowing long-term rental — some ETJ HOAs cap rentals at 20% or ban entirely. Read draft CC&Rs before underwriting DSCR exit.

Build-to-rent DSCR needs lease in place or documented market rent — not broker pro forma alone.

Comparison to DFW pods

Factor	DFW (Collin MUD)	Austin ETJ (Hays/Travis)
Provider	MUD operator + CCN	City ETJ or MUD
Comp fence	ISD (Carroll vs Coppell)	LHISD vs Hays vs Leander
Bottleneck	Production competition	Wastewater capacity queue
Tax	CCAD + MUD bill	Hays/Travis + MUD

Same construction desk, different diligence checklist — see community build DFW.

Verify capacity and fees with provider before LOI — ETJ rules change on annexation and growth moratoria.

Next steps

Annexation risk on ETJ pads

Cities annex ETJ land on growth paths — changes utility provider, code version, and sometimes impact fees retroactive to approved plats. Ask city planning if annexation petition exists within 1 mile of pad.

Moratoria and wastewater treatment capacity

Boom corridors occasionally impose wastewater connection moratoria when treatment plant exceeds capacity — will-serve letters stop until expansion funded. Monitor Buda/Kyle utility board agendas during 90-day due diligence.

Fire flow and commercial tap fees

Pods 10+ doors may trigger fire flow requirements — upsized water main, hydrant contributions $15K–$80K+ on civil bid. Count connections in capacity letter request.

School district comp fence (exurban)

District	Pod buyer pool
Liberty Hill ISD	Austin spillover family
Hays CISD	Kyle/Buda commuter
Leander ISD	Northwest Austin tech

Liberty Hill sold does not comp Kyle pod door — different drive-time and tax.

Partner reporting — monthly draw narrative

Capital partners on $3M pods expect draw logs tied to inspection photos — not “trust me” emails. Align GC pay apps with lender inspection milestones before promising partner updates.
