Do You Need a Permit for Your Remodel? A Plain-English Guide

When Washington remodels require permits, when they don't, and why permitting matters when you eventually sell the house.

Permits feel like bureaucracy until you try to sell a house with unpermitted work in it. Here's a practical read on when they apply.

What this covers

  • Generally requires a permit
  • Generally doesn't require a permit
  • The gray area
  • Why it matters at resale
  • Insurance is the other reason

Generally requires a permit

Moving or adding plumbing, moving or adding electrical circuits, removing or altering load-bearing walls, changing the building footprint, adding or enlarging windows and doors, converting space (garage to living area, basement finishing), and structural repairs. When in doubt, assume yes and confirm.

Generally doesn't require a permit

Painting, flooring replacement, cabinet replacement in the same configuration, countertop replacement, fixture swaps in the same location, and cosmetic tile work that doesn't alter plumbing. Like-for-like replacement is usually the test.

The gray area

Replacing a tub with a shower in the same footprint, or swapping a vanity where the plumbing shifts a few inches. Jurisdictions differ. Your contractor should know your specific city, and if they shrug at the question, that's informative.

Why it matters at resale

Unpermitted work shows up in disclosure and inspection. Buyers can demand it be permitted retroactively, ask for a price reduction, or walk. Retroactive permitting sometimes means opening finished walls. What looked like saving a few hundred dollars becomes a real problem years later.

Insurance is the other reason

If unpermitted work causes damage — a fire from unpermitted electrical, water damage from unpermitted plumbing — your insurer may have grounds to deny the claim. This is the risk nobody thinks about until it matters.

Who pulls the permit

Your contractor should. If a contractor asks *you* to pull the permit as the homeowner, be cautious — it can be a way of shifting liability, and it may indicate they aren't properly registered.

In the Puget Sound specifically

Much of the housing stock across Renton, Seattle, Kent, Tacoma and the Eastside predates 1980, and a large share of Seattle proper predates 1940. That age is what makes these homes worth renovating and also what makes the process less predictable than a new build.

Common questions

Do you handle permits?

Yes. When work requires a permit we pull it — we don't ask homeowners to pull permits for our work.

Can we stay in the house during the remodel?

Usually yes. We seal off work areas and keep sites clean. If it's your only bathroom or kitchen, tell us early so we can sequence around it.
