What a Land Use Attorney Does in Washington

A land use attorney helps property owners, developers, businesses, and neighbors navigate the rules governing what can be built and how land can be used — zoning, permitting, environmental review, and the appeals that follow when a project is denied or a neighbor objects.

In Washington, those rules come from overlapping layers: state statutes like the Growth Management Act and the State Environmental Policy Act, county and city comprehensive plans, and local zoning codes such as Seattle’s Land Use Code. A land use attorney translates that maze into a practical strategy — securing an approval, defending one, or challenging a decision that harms your property.

At Dickson Frohlich Phillips Burgess, our Seattle land use attorneys represent private owners, developers, and public clients across King County and Western Washington at every stage — from permit application to administrative appeal to court.

The Washington Land Use Permit Process

Most development in Washington runs through a local project review process set by state law (Chapter 36.70B RCW) and carried out by each city or county. In broad strokes:

  • Application and completeness. You file a permit application with the local jurisdiction — in Seattle, that is the Seattle Department of Construction and Inspections (SDCI). The review clock does not start until the jurisdiction determines the application is complete.
  • Notice and comment. For many permits, the jurisdiction issues a notice of application and gives neighbors and agencies a chance to comment.
  • Decision. Routine permits are decided administratively by staff. More significant or discretionary permits — variances, conditional use permits, subdivisions — are decided in a quasi-judicial process, often after a public hearing before a hearing examiner.
  • Notice of decision and conditions. The jurisdiction issues its decision, frequently with conditions the applicant must satisfy through later building and engineering permits.

Timing and sequence matter. A poorly prepared application, a missed comment period, or unmet conditions can stall a project for months. Washington’s vested rights doctrine can also work in an applicant’s favor — filing a complete application can lock in the development regulations in effect on that date, protecting a project from later code changes.

We help owners and developers assemble a complete, well-supported application, preserve their vested rights, and anticipate the objections that tend to derail approvals.

Zoning, Variances, and Conditional Use Permits

Zoning determines what you can do with a parcel — the permitted uses, building height, setbacks, lot coverage, and density. In Seattle, those rules live in the Land Use Code (Title 23 of the Seattle Municipal Code); every Washington city and county has its own equivalent. When a project does not fit the code as written, there are established tools:

  • Variance. A variance is permission to depart from a specific dimensional standard — a setback or height limit, for example — where strict application of the code would impose an unusual hardship because of the physical characteristics of the property. Variances are discretionary and are decided against specific legal criteria.
  • Conditional use permit (CUP). Some uses are allowed in a zone only with a permit and conditions that address their impact on neighbors. A CUP is how those uses get approved.
  • Rezone or code amendment. Where the underlying zoning itself is the obstacle, the path may be a site-specific rezone or a change to the regulations.

Larger multifamily and commercial projects in Seattle may also undergo design review by SDCI, which evaluates a building’s form and its relationship to its surroundings. Each of these processes is discretionary, fact-intensive, and frequently contested by neighbors.

We build the record — hardship, compatibility, and consistency with the comprehensive plan — that these approvals turn on, and we oppose applications that would harm our clients’ property.

SEPA and Environmental Review

Washington’s State Environmental Policy Act (SEPA, Chapter 43.21C RCW) requires local governments to consider the environmental impacts of many projects before approving them. Environmental review usually runs alongside the underlying permit, and the jurisdiction issues a threshold determination:

  • a Determination of Nonsignificance (DNS) or Mitigated DNS, if impacts are not significant or can be conditioned away; or
  • a Determination of Significance (DS), which triggers a full Environmental Impact Statement (EIS).

SEPA is one of the most common pressure points in a contested project — both a tool for owners to move a project forward and a basis on which neighbors challenge it. A SEPA appeal is generally consolidated with the hearing on the underlying permit. We handle SEPA strategy on both sides: supporting a defensible determination for an applicant, or challenging an inadequate one.

Comprehensive Plans and Washington’s Changing Zoning Landscape

Under the Growth Management Act (Chapter 36.70A RCW), Washington counties and cities adopt comprehensive plans — long-range blueprints for growth — along with zoning codes that must be consistent with those plans. Comprehensive plans decide where housing, density, and development go, and they directly shape what any individual parcel can become.

This landscape is shifting quickly. Recent state “middle housing” laws (House Bill 1110 in 2023 and House Bill 2321 in 2024) require most Washington cities to allow more housing types — generally up to four units on residential lots and six near major transit stops — in areas formerly reserved for single-family homes.

Seattle has folded these requirements into its One Seattle Plan comprehensive plan update and a corresponding rewrite of the Land Use Code, and King, Pierce, and Thurston County jurisdictions are updating their own plans and codes on staggered deadlines.

For owners and developers, that means both new opportunities and new uncertainty — what a property is zoned for today may not be what it was two years ago. We help clients understand how these changes affect a specific parcel and how to act on them.

Administrative Appeals and Land Use Litigation (LUPA)

When a jurisdiction approves a project you oppose, or denies or over-conditions one you need, there is a defined path to challenge it — and strict deadlines that end the fight if you miss them.

  • Local administrative appeal. Most decisions can first be appealed within the jurisdiction, often to a hearing examiner, typically within a short window (commonly 14 days). This is usually an open-record hearing, sometimes followed by a closed-record appeal to the local legislative body.
  • Judicial review under LUPA. Once local remedies are exhausted, judicial review of a land use decision is governed by the Land Use Petition Act (Chapter 36.70C RCW) — the exclusive route to challenge most local land use decisions in court. A LUPA petition must be filed and served within 21 days of the decision. Washington courts enforce that deadline strictly; a late or improperly served petition is dismissed before the merits are ever heard.
  • Growth board and shoreline appeals. Challenges to a comprehensive plan or a development regulation go to the Growth Management Hearings Board, and shoreline permit decisions go to the Shorelines Hearings Board — separate tracks with their own rules and deadlines.

Because these timelines are short and unforgiving, the time to call a land use attorney is when the decision issues — not weeks later. We handle administrative appeals and LUPA petitions for both applicants and objecting property owners.

Land Use FAQs

How long do I have to appeal a land use decision in Washington?

Usually very little time. A local administrative appeal is often due within about 14 days, and judicial review under the Land Use Petition Act must be filed and served within 21 days of the decision. Courts strictly enforce the 21-day LUPA deadline, so contact a land use attorney as soon as a decision issues.

What’s the difference between a variance and a conditional use permit?

A variance is permission to depart from a specific dimensional standard — like a setback or height limit — when the property’s physical characteristics create an unusual hardship. A conditional use permit allows a particular use that the zone permits only with conditions to manage its impact on neighbors. Different legal standards apply to each.

Does my project need a SEPA environmental review?

Many projects do, though some minor ones are categorically exempt. If SEPA applies, the jurisdiction issues a threshold determination — nonsignificance, mitigated nonsignificance, or significance — and a determination of significance requires a full environmental impact statement. SEPA review usually happens alongside your underlying permit.

Can I challenge how my property is zoned?

Sometimes. If the zoning itself is the obstacle, the path may be a site-specific rezone or a challenge to a development regulation before the Growth Management Hearings Board. If a specific permit decision is the problem, the route is a local appeal and, if needed, a LUPA petition. Which applies depends on what you are actually challenging.

How have Washington’s new “middle housing” laws changed what I can build?

Recent state laws require most cities to allow more housing types in formerly single-family areas — generally up to four units per lot, and six near major transit stops. Seattle and the surrounding counties are implementing these changes now, so a parcel’s development potential may be greater than it was a few years ago. The specifics depend on your jurisdiction and your lot.

When should I involve a land use attorney?

As early as possible — ideally before you file a permit, and immediately if a decision goes against you. Land use processes run on strict deadlines and build a record that is difficult to fix later. Early involvement lets us shape the application or the appeal while it still counts.
