The station record, briefly
NOAA's climate normals for the Vallejo station average 36.1 days a year with a high of 90°F or more, including 7.0 days at 100°F or more. For a house that's being painted while you live in it, the figure is a scheduling note: on hot days, outside work on sun-struck walls may move to early hours, and rooms being painted indoors need airflow without a blast of heat.
Most people don't move out
Unless the whole interior is being stripped back, most families stay at home through a paint job. That works well when the painter plans the job around the household instead of the other way round. Talk through these points before the start date:
- Which rooms go first, and how long each will be out of use.
- Where the crew will set up its materials and cleaning station.
- Which bathroom the crew may use, if any.
- Whether a bedroom can be finished, dried and returned before the next is started.
- How pets and children will be kept away from wet paint and ladders.
A room-by-room rhythm
A typical occupied-home sequence looks like this:
- Empty or center the room. Small items out, large furniture to the middle under plastic.
- Protect the floor. Canvas drop cloths are safer underfoot than loose plastic.
- Remove and bag hardware. Switch plates, outlet covers and curtain rods, labeled by room.
- Repair and sand. Holes and cracks filled, sanded, and the dust cleaned away.
- Prime the repairs, then paint the ceiling, the walls and finally the trim and doors.
- Reset the room so you can use it that night if the paint allows.

Fresh air without the heat
Water-based paints release far less odor than older solvent paints, but every room being painted still needs ventilation. On hot days, painters often open windows early and close up during the hottest part of the day, and keep a fan pushing air out rather than in. Ask about low-odor products if anyone at home is sensitive.
Older paint and lead-safe work
Under EPA's Renovation, Repair and Painting Rule, anyone paid to do work that disturbs paint in homes, childcare facilities and preschools built before 1978 must hold RRP certification, firms included, even sole proprietorships, and their workers must be trained in lead-safe work practices.
When you live in the home during the work, this rule matters even more. If your house was built before 1978, ask whether the firm holds RRP certification; that is the one credential question this page suggests. Then ask how the work area will be sealed off, how dust will be cleaned up each day, and how you'll know the room is ready to use again.
What CSLB says
CSLB says a license is generally required when the total cost of labor and materials on a project is $1,000 or more, or when the project needs a building permit or uses additional workers. The full wording sits behind the source link in the card below.
Keeping the peace with a crew in the house
- Agree on arrival and finish times.
- Decide where shoes, tools and ladders stay overnight.
- Keep a short list of anything that must not be moved.
- Ask who to call if a problem comes up while you're out.
- Plan a walk-through at the end of each room, not just at the end of the job.
If you are painting outside too
Exterior work can run alongside the interior. It just needs its own plan: washing, scraping, priming and two topcoats, scheduled around the hours when the walls are shaded and dry. Our exterior painting page explains the steps, and our pricing guide covers why an occupied home can take longer to paint.
