Mountain View / Bathroom remodeling
Bathroom Remodeling in Mountain View
Moving one wall turns a one-week Mountain View permit into a two-month one.
Mountain View requires a permit for every bathroom remodel, and the city publishes two very different timelines depending on whether walls move. We remodel bathrooms here with that line drawn at the first visit, plus the 2026 reach code and SVCE rebates planned in.
MOUNTAIN VIEW AT A GLANCE
What shapes a Mountain View bathroom.
Mountain View is a city of older housing and many renters, it has its own reach code, and it publishes exact permit timelines for bathrooms. Here is where each piece comes from.
- 1975
- median year a Mountain View home was built
- 60%
- of homes built before 1980
- 61%
- of households rent, 2024 Census estimate

Fixtures in place, or walls moving?
The city quotes 5 to 7 days for a permit when fixtures are upgraded in the same location, and 6 to 8 weeks when structural parts such as walls are removed or added. The plan is a single 8.5 by 11 inch sheet showing the existing and new layout either way. We show you both paths before any design is final.
Tub and shower
Replacing a tub or shower enclosure needs a permit. Shower walls are finished with a non-absorbent surface at least 72 inches above the floor, with tempered or laminated glass.
Layout changes
Removing or adding walls moves the job into a 6 to 8 week permit path with a 2 week first review, so structural work is decided before tile is chosen.
Electrical
GFCI on every receptacle, an outlet within 3 feet of each basin and a dedicated 20 amp circuit. At least one light on a vacancy sensor.
Ventilation
Any bathroom with a tub or shower needs an exhaust fan switched separately from the light. Mountain View does not accept an operable window instead.
Water heater and reach code
Since January 1, 2026, installing gas equipment during a remodel triggers electric-ready prewiring. A heat pump water heater instead can earn SVCE and city rebates.
Fixtures
New toilets 1.28 gallons per flush or less, showerheads 1.8 gpm, faucets 1.2 gpm. Older noncompliant fixtures elsewhere may need replacing under SB 407.
TWO PERMIT PATHS
Which timeline your bathroom gets.
Mountain View splits bathroom permits by scope. The difference is weeks, so the scope is settled before the plan is drawn.
5 to 7 day permit when
- Fixtures are upgraded in the same locations
- Walls, structure and the exterior stay as they are
- The one-page plan shows existing and new layouts
- Comments come back in 5 business days
6 to 8 week permit when
- A wall is removed or a new one is built
- Structural framing is modified
- Exterior changes need Planning review first
- Each review cycle takes about 2 weeks
No permit needed for
- A standard toilet replaced in the same spot, 1.28 gpf or less
- Painting, papering and similar finish work outside a remodel
- Stopping a leak without replacing pipe

Planning the work
How a Mountain View bathroom project runs.
Site visit
Free visit. Layout, framing, the panel and the water heater, and whether any wall has to move.

Demolition and rough-in
Plumbing, electrical and waterproofing, inspected before tile. Inspections requested by 3pm are set for the next business day.
Finishes and final
Tile, fixtures and lighting, then the final inspection by the City Building Inspector and rebate paperwork.
WHAT SLOWS MOUNTAIN VIEW REMODELS
Problems Mountain View homeowners run into, and how we plan around them.
From Mountain View residents' own posts, local news and the city's permit pages.
Permits take longer than the city's published estimate, and residents call Mountain View slower than its neighbors.
We submit complete packages and check status weekly, calling the Building Division when a review stalls instead of waiting.
A homeowner cannot tell whether the permit is really delayed or the contractor never filed it.
You get the permit number on submittal so you can look it up yourself, and every city comment is forwarded the day it arrives.
A small layout change quietly turns a one-week permit into a two-month one.
Fixture-in-place and wall-moving options are drawn side by side at the site visit, with the permit path for each.
A panel upgrade to carry new circuits ends in PG&E asking to trench through the city sidewalk.
Panel capacity is checked first, and if service work is needed, the PG&E route and the city excavation permit are settled before demolition.
Older homes hide noncompliant fixtures elsewhere that must be updated before final.
SB 407 fixture replacements are listed in the scope from the start, so they do not surface at the final inspection.

Do I need a permit to remodel a bathroom in Mountain View?
Yes. Mountain View requires a building permit for every bathroom remodel, including replacing a tub or shower enclosure. Swapping a toilet in the same location for one of 1.28 gallons per flush or less is the main exception. Plumbing and electrical permits are added when that work is part of the job.
How long does a bathroom permit take in Mountain View?
5 to 7 days when fixtures are upgraded in the same location, and 6 to 8 weeks when walls or other structural parts change. City staff return first comments in 5 business days for like-for-like work and in 2 weeks for structural work.
What are the permit fees for a bathroom remodel in Mountain View?
From $800 including inspections, according to the city, scaling up with the size of the bathroom. The exact fee is confirmed during prescreening after the online submittal and paid online before the permit is issued.
Does Mountain View's reach code affect a bathroom remodel?
Yes, if gas equipment is installed. Since January 1, 2026, remodels that install gas or propane equipment must include electric-ready prewiring for that area, under Ordinance No. 9.2025. A bathroom with no gas appliance is not affected.
Can a window replace the exhaust fan in a Mountain View bathroom?
No. Mountain View requires an exhaust fan in every bathroom with a tub, shower or combination, switched separately from the lights, and states that an operable window is not a permissible means of humidity control.
What rebates are there for a heat pump water heater in Mountain View?
Up to $4,500 combined in many cases. SVCE pays $2,500 for replacing a gas water heater with a heat pump model ($3,500 income-qualified), and the City of Mountain View adds $2,000 while its funds last. Both require applying before installation.
