When David started planning his 40x60 workshop in Lakewood, he thought the process would be straightforward: find a contractor, get a quote, and start building. Six months later, after dealing with three different contractors, permit delays, and budget overruns, he wished he had known what he was getting into.
David's story isn't uncommon. Over 15 years, we've seen dozens of projects go sideways due to poor planning. But we've also guided hundreds of successful projects from concept to completion. Here's the step-by-step process that ensures your post-frame building project succeeds.
Phase 1: Project Definition (Week 1-2)
The Puyallup Auto Shop Success Story
The Challenge: A mechanic needed a 30x40 auto repair shop but had never built anything before. His initial "requirements" were simply "somewhere to fix cars."
Our Planning Process:
- Function analysis: How many bays? What equipment? Customer area?
- Future planning: Growth projections for 5-10 years
- Workflow design: Traffic patterns for vehicles and customers
- Code requirements: Commercial auto repair regulations
- Budget realities: Total project cost vs. available financing
Results: Clear project scope that prevented costly changes during construction. Final building exceeded expectations while staying within budget.
Essential Planning Questions
Before contacting any contractor, answer these questions:
Primary Function:
- What will happen in this building daily?
- What equipment or vehicles must it accommodate?
- How many people will use it simultaneously?
- Will functions change seasonally?
Size Requirements:
- Minimum dimensions for current needs
- Ideal dimensions for optimal function
- Maximum size property/budget allows
- Expansion possibilities
Performance Requirements:
- Insulation needs (climate control vs. basic weather protection)
- Electrical requirements (basic vs. heavy equipment)
- Plumbing needs (none vs. basic vs. full facilities)
- Special features (cranes, compressed air, etc.)
Phase 2: Site Analysis and Zoning Research (Week 3-4)
The Gig Harbor Setback Crisis
The Problem: A client designed their dream 50x80 barn before checking local regulations. Pierce County's rural setback requirements meant the building had to be 75 feet from any property line - impossible on their 2-acre lot.
The Solution: We redesigned as a 40x60 building positioned to meet setbacks while adding a 20x40 lean-to later for the same total space.
Lesson Learned: Always research restrictions before finalizing design.
Zoning Research Checklist
Setback Requirements:
- Distance from property lines (front, side, rear)
- Distance from existing structures
- Distance from wells, septic systems, or wetlands
- Special requirements for corner lots or waterfront properties
Height and Size Restrictions:
- Maximum building height
- Maximum coverage percentage of lot
- Maximum square footage for accessory buildings
- Restrictions on commercial use in residential zones
Use Restrictions:
- Permitted vs. conditional uses
- Home business regulations
- Environmental restrictions
- Historic district requirements
Phase 3: Site Evaluation and Engineering (Week 5-6)
The Yelm Soil Surprise
Unexpected Challenge: A simple horse barn project hit 3 feet of peat bog under what appeared to be solid ground. Standard post-frame construction wouldn't work.
Our Solution: Concrete piers down to the gravel layer with post-frame structure above grade. Added $8,000 to the project but prevented future settling issues.
Key Point: Site evaluation before design saves money compared to design changes during construction.
Professional Site Evaluation
Soil Assessment:
- Soil type and bearing capacity
- Drainage characteristics
- Seasonal water table levels
- Presence of rock, sand, clay, or organic materials
Topographic Analysis:
- Natural drainage patterns
- Required grading and excavation
- Access routes for construction
- Views and solar orientation
Utility Assessment:
- Distance to electrical service
- Water and septic system locations
- Internet and phone service availability
- Propane or natural gas access
Phase 4: Design Development (Week 7-10)
The Tacoma Workshop Evolution
Initial Request: "We need a 30x40 workshop."
Final Design: 36x48 workshop with 12x36 lean-to, office area, and customer parking.
Design Process:
- Function mapping: Identified workflow patterns and space needs
- Equipment planning: Sized spaces for current and planned equipment
- Traffic analysis: Separated customer and work areas
- Growth accommodation: Designed for lean-to addition
- Code compliance: Met commercial workshop requirements
Result: Building that functions better than initially envisioned while meeting all regulatory requirements.
Design Development Process
Functional Layout:
- Work area sizing and configuration
- Traffic flow patterns
- Storage requirements and locations
- Separation of different functions
Structural Design:
- Building dimensions and height
- Door and window locations
- Load requirements (equipment, storage, snow)
- Foundation type and specifications
Systems Integration:
- Electrical load calculations and panel location
- Plumbing rough-in requirements
- HVAC planning and equipment sizing
- Internet/phone infrastructure

Common Planning Mistakes and How to Avoid Them
Mistake 1: Underestimating Site Complexity
Example: A Federal Way client planned a simple 30x40 garage. During construction, we discovered underground utilities, poor drainage, and protected trees - adding 6 weeks and $12,000.
Prevention: Professional site evaluation before design finalization.
Mistake 2: Inadequate Electrical Planning
Example: A Tacoma workshop was designed with basic electrical, but the client's equipment required 220V service throughout. Retrofitting added $8,000.
Prevention: Equipment load analysis during design phase.
Mistake 3: Permit Surprises
Example: A rural Pierce County barn triggered environmental review due to seasonal creek proximity, delaying the project 8 weeks.
Prevention: Early consultation with building department.
Regional Planning Considerations
Pierce County Specifics
- Rural areas: Environmental review for critical areas
- Soil conditions: Marine clay requires deeper foundations
- Permit timelines: 4-6 weeks for standard projects
- Setback requirements: Vary significantly by zoning
King County Considerations
- Urban areas: Design review for aesthetics
- Environmental sensitivity: Steep slope and wetland regulations
- Permit complexity: More detailed review process
- Utility requirements: Higher connection standards
Thurston County Factors
- Agricultural zoning: Opportunities for larger buildings
- Flood zones: FEMA requirements near rivers
- Historic districts: Design compatibility requirements
- Growth management: Urban vs. rural development rules
