Office Renovation Budget Template

The difference between a project that stays on budget and one that blows it usually isn't the big-ticket items — it's the 30 "small" costs nobody accounted for. This template covers every category so nothing falls through the cracks.

Budget Summary Framework

Category	% of Total Budget	Cost Range (per SF)
Pre-construction / design	8-12%	$5-15/SF
Hard construction	45-55%	$30-80/SF
Furniture	20-30%	$15-50/SF
Technology / AV / cabling	8-12%	$8-20/SF
Move management	2-3%	$2-5/SF
Contingency	10-15%	Varies

Pre-Construction & Soft Costs

• Architecture / design fees — $5-15/SF or 8-12% of construction cost. Includes space planning, construction documents, and construction administration.
• Permits and fees — Building permits, fire marshal review, health department (for kitchens). Budget $2,000-10,000 depending on jurisdiction and scope.
• Engineering (MEP) — Mechanical, electrical, plumbing engineering. Often included in architect's fee but sometimes separate, especially for complex HVAC work.
• Environmental testing — Asbestos survey required in most pre-1980 buildings before demolition. Budget $2,000-5,000 for testing; remediation is additional.
• Project management — If hiring an owner's rep or PM firm, budget 3-5% of total project cost.

The Top 5 Budget Busters

1. Scope creep during design — "While we're at it..." additions during construction cost 2-3x what they would have cost if planned upfront.
2. After-hours work requirements — Many occupied buildings require noisy work after 6pm. This adds 15-30% to labor costs.
3. Existing conditions surprises — Asbestos, undersized electrical panels, non-code-compliant elements. Budget 10-15% contingency to cover these.
4. Furniture lead times causing delays — If furniture arrives late, you're paying rent on a space nobody can use. Order furniture as soon as the floor plan is locked.
5. Not including tax — Sales tax on furniture and materials ranges from 0-10% depending on state and local rates. It's always more than you think.
