What to Know About Bathroom Renovation in Hillsborough
Local building codes, neighborhood character, and permit requirements vary by city. Here's what Hillsborough homeowners should know before starting a project.
- 01Hillsborough homes built before 1950 frequently have lead paint, asbestos tile, and galvanized plumbing — professional abatement and replumbing should be budgeted for bathroom renovations
- 02The ADRB does not typically review interior-only bathroom renovations, but any window changes visible from the street require review and approval
- 03Many Hillsborough homes have original radiant heating systems (hot water loops in the floor slab) that must be carefully navigated during bathroom demolition to avoid system damage
- 04Water pressure in Hillsborough is generally strong from Cal Water, but older homes may have undersized copper supply lines (1/2") that should be upgraded to 3/4" during renovation
- 05Hillsborough's building department is responsive and thorough — bathroom permits with plumbing and electrical changes are typically processed in 3-5 weeks

Bathroom Renovation in Hillsborough: FAQ
Answers to common questions from Hillsborough homeowners.
Primary bathroom renovations in Hillsborough take 8-12 weeks of construction. Historic homes with lead paint or asbestos remediation may add 1-2 weeks. Guest bathrooms and powder rooms take 4-6 weeks. Custom stone fabrication lead times (4-6 weeks) should be factored into the overall project timeline.
Yes — many Hillsborough bathrooms, especially in pre-war homes, are undersized by today's standards. We enlarge bathrooms by borrowing space from adjacent bedrooms or closets, which avoids exterior changes and ADRB review. If a bump-out or addition is needed, we manage the full ADRB approval process.
We study the home's architectural style and period details — molding profiles, proportions, materials, hardware — and design bathrooms that feel like they belong. For a 1930s Tudor, that might mean arched shower entries and iron fixtures. For a 1950s colonial, clean lines and marble wainscoting. The result is a bathroom that feels both new and authentically part of the home.
In Hillsborough homes built before 1970, we strongly recommend replacing supply lines (often galvanized steel) and drain lines (often cast iron) while walls are open. This is a one-time opportunity to prevent future plumbing failures that could cause water damage. The incremental cost is typically $3,000-$8,000 — a wise investment in a home of this caliber.
Electric radiant heat mats installed under tile or stone are our standard recommendation. Some Hillsborough homes have existing hydronic radiant systems — if functional, we can integrate the bathroom into that system. New electric systems cost $3,000-$5,000 depending on bathroom size and include programmable thermostats.
Freestanding soaking tubs are one of the most requested features in our Hillsborough bathroom renovations. We install Victoria + Albert, Bain Ultra, and MTI tubs with floor-mounted fillers in polished nickel or unlacquered brass. We verify floor structure can support the filled weight (typically 800-1,200 lbs) and reinforce framing as needed.
