Plano Setbacks & Height Limits — Residential Zones

Last updated: Verified:

Fact-checked against the City of Plano Zoning Ordinance posted in 2026 on September 20, 2026.

Plano's current residential zoning districts include SF-20, SF-9, SF-7, and SF-6. The previous version of this page listed an SF-12 district, but SF-12 is not in the current residential-district list in Article 9.

Current Standard Single-Family Requirements

The current Article 9 tables give these standard requirements:

Zone Min. Lot Area Front Interior Side Street Side Rear Max. Height
SF-20 20,000 sq ft 35 ft 10 ft or 10% of lot width, whichever is greater 15 ft 10 ft 40 ft*
SF-9 9,000 sq ft 30 ft 7.5 ft or 10% of lot width, whichever is greater 15 ft 10 ft 35 ft / 2 stories
SF-7 7,000 sq ft 30 ft 6.5 ft or 10% of lot width, whichever is greater 15 ft 10 ft 35 ft / 2 stories
SF-6 6,000 sq ft 25 ft 6 ft or 10% of lot width, whichever is greater 15 ft 10 ft 35 ft / 2 stories
  • In SF-20, the ordinance allows up to three stories and 40 ft, but the third story may not exceed 10% of the building's total floor area.

The previous page also understated several front and side yards and overstated rear yards.

Stormwater Incentive Options

SF-9, SF-7, and SF-6 include alternate Stormwater Incentive Option 1 and Option 2 standards.

For example:

  • SF-9 standard front yard: 30 ft; incentive options: 25 ft.
  • SF-7 standard front yard: 30 ft; incentive options: 25 ft.
  • SF-6 remains 25 ft under the listed standard and incentive columns.
  • Standard maximum coverage is generally 45%, with 47.5% and 50% options where the ordinance's stormwater-quality conditions are met.

These incentive standards should not be treated as automatic rights on every lot; the ordinance specifies when the subdivision may use them.

Alley-Served Lots and Other Exceptions

The district sections contain additional yard rules. For example, alley-served garages in SF-7 must be set back at least 20 ft from the rear property line.

SF-6 also contains a specific alley-served option allowing a 20-ft front yard when the rear yard is increased from 10 ft to 15 ft, with the garage set back at least 20 ft from the rear property line.

Planned Developments

Many Plano properties have PD conditions or other site-specific standards. A base SF designation therefore may not tell the whole story.

Confirm the complete zoning label and the applicable PD ordinance before relying on the base Article 9 table.

How to Check a Property

  1. Confirm the complete zoning designation and any PD number.
  2. Read the current Article 9 section for SF-20, SF-9, SF-7, or SF-6.
  3. Determine whether a Stormwater Incentive option actually applies.
  4. Check alley, garage, corner-lot, accessory-building, and general yard provisions.
  5. Confirm parcel-specific questions with Plano Planning before final design.

FAQ

What are the setback requirements for single-family zones in Plano?
Plano's standard single-family residential districts (SF-7, SF-9, SF-12) require a 25 ft front setback and 5 ft interior side setbacks. Rear setbacks are 15 ft in SF-7 and 20 ft in SF-9 and SF-12. Always verify your specific zoning district on the Plano zoning map before finalizing plans.
What is the maximum building height in Plano residential zones?
Maximum building height in Plano's single-family residential districts (SF-7, SF-9, SF-12) is 35 feet, measured from average grade to the highest point of the roof. Multi-family districts like MF-1 allow up to 45 feet. Overlay districts and planned development (PD) zones may change these limits.
How is lot coverage calculated in Plano?
Lot coverage is the percentage of the lot covered by buildings and roofed structures. Plano's single-family zoning districts typically cap building coverage in the 40-45% range depending on district, with the exact standard listed in the Zoning Ordinance section for your district. Driveways and uncovered patios are generally excluded.
Can I build closer to the property line than the setback allows?
Only if you receive a variance from the Zoning Board of Adjustment or if your project qualifies for a specific encroachment allowance in the Zoning Ordinance (for example, eaves, chimneys, or open porches may project a limited distance). Variances require a public hearing and a demonstrated hardship specific to your lot.
