Waco's Accessory Structures: The Rules That Matter

Every city handles accessory structures a little differently. In Waco, Texas, there are 8 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Carport Rules

Waco Zoning Code Sec. 28-906 allows carports in side and rear yards no closer than 2 ft to a side or rear lot line, no closer than 5 ft to any principal dwelling on an adjacent lot, and no closer than 10 ft from the rear lot line if accessed from an alley.

Key details: Side/Rear Setback: 2 ft min (carport). Alley Setback: 10 ft min from rear lot line. Adjacent Dwelling: 5 ft min separation. Rear Yard Coverage: Max 30% (all accessory). Permit: Required for residential carport.

Building a carport closer than 2 ft to a lot line, encroaching the alley setback, exceeding the 30% rear-yard coverage cap, or skipping the building permit can result in stop-work orders, code enforcement citations, and an order to remove or relocate the structure. Setback violations also surface during real estate inspections and can block resale or refinancing.

ADU Impact Fees

Waco charges standard water/wastewater impact fees on ADUs requiring new connections under authority of Texas Local Government Code Chapter 395. Building permit fees are based on construction valuation through Planning Services. Texas has no statewide ADU fee waiver. Sharing the principal dwelling's existing water/sewer tap is the most common cost-reduction strategy for Waco property owners.

Key details: Permit Fee Range: $400-$1,200 typical. Water Impact Fee: ~$2,000-$4,000 (new tap). Wastewater Impact: ~$1,800-$3,500. State Authority: TX LGC Ch. 395. State Waiver: None — Texas has no ADU exemption.

Failure to pay impact fees results in permit denial or Certificate of Occupancy delay. Building or occupying an ADU on an unauthorized utility connection is a building code violation. Texas Local Government Code § 54.001 authorizes civil penalties up to $500 per day for zoning violations and $2,000 per day for building/fire violations.

ADU Owner Occupancy

Waco typically imposes owner-occupancy as a condition of any Special Use Permit granted for accessory dwelling units under Waco Code Chapter 28. The owner must occupy either the principal dwelling or the ADU as a permanent residence, with a recorded deed restriction filed with the McLennan County Clerk. Texas Local Government Code Chapter 211 preserves local zoning authority — no state preemption applies.

Key details: Code Section: Waco Code Ch. 28 (SUP). Owner Occupancy: Required (typical SUP condition). Deed Restriction: Recorded with McLennan County Clerk. Baylor Area: Heightened enforcement. Both Units Rented: Prohibited (single-family district).

Operating an ADU without satisfying owner occupancy is a code violation. The city may revoke the SUP and Certificate of Occupancy and refer the matter to Municipal Court. Fines up to $500 per day apply under Texas Local Government Code § 54.001. Both units rented to non-owners in a single-family district can trigger a stop-use order.

Compared to other cities, Waco takes a harder line on adu owner occupancy. The enforcement and penalty structure reflects that.

ADU Permits

Waco regulates accessory dwelling units under the Waco Zoning Ordinance (Code of Ordinances Chapter 28). Detached ADUs (commonly called accessory dwelling units or guest quarters) typically require a Special Use Permit (SUP) or are limited to specific zoning districts under Chapter 28. Building permits issue through the Planning Services Department only after zoning approval. Texas Local Government Code Chapter 211 preserves municipal zoning discretion — no state ADU preemption applies.

Key details: Code Section: Waco Code Ch. 28 (Zoning). Review Type: Special Use Permit (typical). Timeline: 2-4 months zoning + permit. Detached Max Size: ~600-800 sq ft typical. State Authority: TX LGC Ch. 211.

Building an ADU without zoning approval and a building permit is a Class C misdemeanor under the Waco Code with fines up to $2,000 per day for building/fire code violations and $500 per day for zoning violations under Texas Local Government Code § 54.001. The city can order removal and place a lien for abatement costs.

Compared to other cities, Waco takes a harder line on adu permits. The enforcement and penalty structure reflects that.

ADU Rental Restrictions

Waco ADUs may be rented long-term (30+ days) provided owner occupancy continues under the typical SUP condition. Short-term rentals (under 30 days) are regulated under the Waco STR ordinance with registration, hotel occupancy tax collection (Texas Tax Code Chapters 156/351), and zoning-based restrictions. STRs near Magnolia Market, Baylor University, and the Silos see the highest density and the most active enforcement.

Key details: Long-Term (30+ days): Permitted with owner occupancy. STR Registration: Required with city. State HOT: 6% (TX Tax Code Ch. 156). City HOT: Up to 7% (TX Tax Code Ch. 351). Combined HOT: ~13% on stays < 30 days.

Operating an unregistered STR carries fines up to $500 per day under Texas Local Government Code § 54.001 and is a Class C misdemeanor. Unpaid hotel tax accrues penalties and interest under Texas Tax Code Chapter 156. Waco monitors Airbnb and VRBO listings and pursues unregistered operators.

Compared to other cities, Waco takes a harder line on adu rental restrictions. The enforcement and penalty structure reflects that.
