Tacoma Work/Live Code for Historic Redevelopment
Search code innovationsEnter a keyword to search for code innovations.
Tacoma Building, Fire and Historic Preservation officials worked with local architect Ben Ferguson to adopt an innovative Live/Work Work/Live code amendment in 2012. Tacoma has a lot of historic buildings with an uncertain future, but the LWWL code makes it easier to adapt existing buildings for modern urban life. By reducing regulatory and financial barriers by not requiring change of use, they have provided a clear path to approval for a new mixed-use building type that caters to today’s market.
Origin and purpose
Ferguson was concerned for the fate of many historic unreinforced masonry (URM) buildings in Tacoma, so he helped spearhead the Work/Live code amendment to facilitate redevelopment of existing commercial buildings into their highest and best use. This followed decades of momentum with “Live/Work” codes which gained popularity in the 1960s as a response to the de-industrialization of America’s inner cities. Live-work allows residents to operate small businesses as a secondary use of their unit; Work/Live code is the inverse of Live/Work: it allows a commercial building to contain a residential unit, so people can live where they work, i.e. the business use is primary with residence a secondary use. Otherwise known as “Zero-Commute Housing” work-live and live-work eliminate the need to travel to work, provide affordable housing and commercial space, and encourage small business.

|City of Tacoma Live/Work and Work/Live Code Amendments, adopted by Ordinance No. 28237 on November 3, 2015, codified in Tacoma Municipal Code (TMC) Sec 2.02.100 and Sec 202.135; TMC Land Use Code Sec 13.06; and TMC 6B.145||Live/work and work/live uses allow a nonseparated commercial business and a residential use within the same space.|
|2015 International Building Code, Section 419||Allows Live-Work Uses in R-2 Occupancies.|
Code Development and Adoption
Prior to their adoption in 2012, there were no specific land use code provisions for live/work and work/live development in Tacoma. The amendments provided a basic framework for where and how these uses would be allowed. The City then hired BLRB Architects in 2013 to conduct a
consultant study on code compatibility with the existing provisions in the City’s Building Code. The study documents code precedents from other jurisdictions as well as three existing building case studies in Downtown Tacoma. It offered specific recommendations to address Building and Fire Code roadblocks to the renovation and reuse of existing buildings, and identified existing provisions within the Land Use Regulatory Code that should be reevaluated.
Then in 2015, City staff proposed revisions to the Land Use Regulatory Code as incremental improvements to the original amendments adopted in September 2012. The Planning Commission held a public hearing on July 15, 2015, followed by a City Council Public Hearing on September 29. The City Council adopted the proposed code amendments pertaining to live/work and work/live uses on November 3, 2015. Posted below are the Council ordinance adopting the regulations and a tip sheet for interested parties and prospective permit applicants.
Application and Scope
Work-Live is defined as a commercial space with an unseparated residential accessory use. A work-live unit is the inverse of a live-work unit (an unseparated commercial use in a residential space) but the two types of units share nearly identical design principles. The goal of both codes is to enable small businesses to share residential space and to minimize commuting and financial barriers for tenants. In Tacoma, Work-Live is allowed in assembly (A), office/café/business (B), retail (M), and light manufacturing (F) occupancy classifications that are smaller than 3000 square feet..
The Work-Live ordinance is intended to lower regulatory and financial barriers for redevelopment. Tacoma has a large stock of heritage properties with permitted uses that are obsolete for their intended uses. Examples include small footprint downtown warehouses and narrow plan office buildings. These building typologies are ideal for residential uses but the cost of changing their use to residential is cost-prohibitive within current market rents. Work-Live allows a residential use in a commercial use building without changing the original occupancy classification.
Work-Live use is also ideal for small retail buildings in mixed-use centers where the back half of a building can be converted into an apartment with the street frontage remaining a retail or commercial use. Another ideal W-L building type is retail spaces with chronic vacancy. Work-Live allows short to mid-term use of a street level tenant space that can easily be converted back to retail when consumer demand is higher. Work-Live enables a property owner to realize short-term revenue without eliminating the potential of future retail.
Work-Live is an allowable use within the City of Tacoma with no additional approvals required. The city created a predictable approval process that does not rely upon staff discretion. Work-Live improvements must include all required life-safety aspects of both the original commercial use and R-2 residential. Building permit application must identify the business space with a distinct and definable separation from the living space, which does not need to be a firewall separation (subject to requirements – see below).
Additional limitations apply including:
- New construction can contain no more than 20 units.
- Subject to a conditional live/work and work/live agreement license and City of Tacoma business license.
- Residential portion must be inhabited by the operator or an employee of the business. The work and living spaces cannot be leased separately from each other.
- Residential portion of the unit limited to one family.
- Certificate of Occupancy required for the specific commercial use required for work/live units.
Internal staff discussions after the conclusion of the committee recommendation resulted in stricter sprinkler upgrade requirements than originally intended. The fire department was concerned about residential uses co-located with retail shelving storage. High density storage can result in very intense fires that would overwhelm Type 13-R or Type 13-D systems. Code language was adapted to require full NFPA Type 13 sprinklers in unseparated units. Separated units can utilize the less expensive NFPA Type 13-R and Type 13-D sprinklers.
Only one project to date has utilized the Tacoma Work-Live ordinance, currently in construction as of March 2017: The Mckinley Station Lofts are converting an existing building previously occupied by the Tacoma Police Dept into 14 loft style work/live and live/work residential units. The west half the building is being constructed as residential (live/work) and the east half is being constructed as commercial (work/live). This distinction was vital to the success of the project, since residential uses are prohibited at street level on McKinley Ave, a designated core pedestrian street per our land use codes (See related project case study – forthcoming). No other projects have been completed to-date.
Multiple additional property owners are exploring the viability of work-live for their investment properties. Ferguson Architecture has actively been working with one owner for a renovation to activate vacant street level retail for their downtown Tacoma multi-floor apartment building.
It is too early to identify whether the Work-Live code will be a valuable tool to rehabilitate Tacoma’s vast existing building stock. It is also too early to determine whether the Work-Live ordinance language creates code flexibility without being vulnerable to development professionals who attempt to avoid necessary life-safety requirements.
Other cities have implemented Work-Live ordinances but have approached the code regulations differently. There was a major fire in a Work-Live project in Oakland on December 6, 2016. Thirty-six people lost their lives and the Oakland government is investigating code modifications. The Tacoma version of Work-Live would not allow similar uses that led to the fire.
EXEMPTIONS FOR EXISTING BUILDINGS
Existing buildings converting to live/work or work/live uses may be able to take advantage of some exemptions in the zoning and building codes. For buildings lawfully in existence prior to December 5, 1989:
- No additional parking is required for live/work or work/live units.
- Buildings may be partially equipped with sprinkler systems provided all stories with work/live uses and any stories/basements below those uses are fully sprinklered.
- Buildings with 4 or fewer units may be able to use NFPA 13D or 13R sprinkler systems.
For historic buildings, up to 10% of new floor area may be added in which external additions and alterations are exempt from all prescriptive design standards contained within TMC 13.06.500 and TMC 13.06A.
Offsite improvement requirements may be waived for live/work buildings with less than 10 units, or work/live buildings less than 30,000 square feet in area.
Tacoma’s Work-Live ordinance was designed as a Tacoma amendment to the International Building Code (IBC). By working within the IBC the City is able to use conventional plan review processes which eliminates costs of additional oversight. No additional fees are required by permit applicants. No incentives are proposed or necessary for this policy, the policy is a lower-cost method of development.
The intent of Tacoma’s Work-Live ordinance is to minimize regulatory barriers to adaptive reuse of underutilized buildings without compromising the safety and welfare of the public and emergency responders. Tacoma has a large stock of poorly performing buildings. Tacoma initiated discussions with property owners to identify the reasons their properties were underperforming and why they had not further developed their properties to overcome the issues. The two most common responses were low lease rates and the high cost of changing the existing undervalued use to a higher demand residential.
It is too early to determine if the Work-Live ordinance will eliminate barriers to adaptive reuse. Multiple projects are in development as of March 2017.
The ordinance development process included collaborative meetings between a private consultant and city staff. Staff members included the building permit reviewers, planning permit reviewers, and fire department permit reviewers. The primary challenge to overcome was maintaining fire safety of residential occupants and emergency responders.
Commercial buildings have a lower level of emergency response than a residential building. Fire personnel are required to sweep residential buildings for occupants during a fire event. Once a residential use is possible within a building the responders must verify the building is empty. Fire Department personnel were primarily concerned with providing sprinkler systems to any building that contained residential use. The committee agreed to a graduated and phased approach to sprinklers to minimize first cost without placing occupants and emergency personnel at risk. Type 13-R and 13-D systems were approved for projects with four or less units that have separated commercial and residential areas. Full Type 13 systems are required for unseparated uses and projects with greater than four units. Unsprinklered buildings that would be partially occupied with W-L units would be required to fully sprinkler the units without immediately providing sprinklers for the remaining non-Work-Live spaces. Future substantial improvements for non-Work-Live units are required to be upgraded on a space by space basis.
Future Outlook and Replicability
The Work-Live ordinance is likely to remain an indefinite part of the Tacoma amendments to the IBC. No additional processes are required for the code to be maintained. The two most likely reasons the code would be eliminated are if a flaw is identified that causes unintended life-safety danger with the Tacoma code or if there are further life-safety issues on a national scale with the Work-Live movement. The Ghost Ship fire in Oakland has fire officials concerned and they are watching the investigation closely.
The State of Washington was the approving agency for the Tacoma amendments. It is possible for other local jurisdictions or the State of Washington to add Work-Live code amendments to the IBC in the future.
