Residential Infill Pilot Program


The intent of the Infill Pilot Program is to promote innovative residential infill while ensuring that such infill demonstrates high quality building and site design that is responsive to and harmonious with neighborhood patterns and character. The City hopes to see successful and well-regarded examples of these housing types built, as a way to inform future Council decisions on Tacoma’s regulatory approach to these housing types.

Two-Family Housing: 6 spots available in each Council District  

Planned Infill Housing will allow applicants to develop a project that meets the density requirement of the One Tacoma Comprehensive Plan and responds to the specific site conditions and  the needs of the occupants.      


Planned Infill Housing: 6 spots available in each Council District

Two-family housing in single-family zoning creates opportunities for infill on corner lots that maintain the scale and character of single-family buildings while utilizing two public edges of the property as front yards and entries.


Small Multi-Family Housing: 6 spots available in each Council District 

Small Multi-family housing in lower-density zoning increases density while preserving the neighborhood character through appropriate building massing and setbacks.


Cottage Housing: 6 spots available in each Council District 

Cottage housing provides a transition between single family housing neighborhoods and higher density areas, creating a development pattern that maximizes land values, reduces infrastructure costs and typically provides housing next to services.

Residential Infill Pilot Program 2.0 Adopted Process

The Tacoma City Council adopted Ordinance 28695 on October 20, 2020, updating the Infill Pilot Program to:   


1. Expand Infill Housing Types:

  • Add Planned Infill Housing category (previously referred to as density-based)
  • Increase the number of each housing type allowed through the program

2. Modify design requirements and other standards:

  •  Allow Cottage Housing in rear yards when an alley is present
  • Increase flexibility for the two-family housing type by removing the requirement to be on a corner lot, and to present the general appearance of a detached single-family dwelling
  • Increase emphasis on qualitative design review of all categories
  • Other changes for improved design outcomes, program clarity and consistency with Building Code
  • Remove parking requirement for projects reviewed by the Infill Pilot Program

3. Streamline the permit process

  • Integrate the Infill Pilot Program review process into the Conditional Use Permit process (rather than requiring both separately)
  • Update handbook to reflect changes and promote quality and performance through improved guidance.

    4. Update handbook to reflect changes and promote quality and performance through improved guidance.
