These are planning ranges for typical 2026 projects, not quotes. Every project is priced after a site visit.
Hillsborough is unlike anywhere else on the Peninsula. It is entirely residential — no commercial districts at all — with large minimum lot sizes, no sidewalks, and homes set well back behind mature landscaping. The housing ranges from 1920s and 30s estates through mid-century homes to substantial recent construction.
Work here is almost always whole-home renovation rather than single-room remodeling. Owners are reworking how an entire property functions, often over a longer horizon than a typical remodel, and the level of finish expected is high.
The older estates carry genuine architectural significance along with a century of systems that need attention. The mid-century homes are frequently excellent houses that want thoughtful modernization rather than replacement.
Hillsborough is a town rather than a city, and it is run accordingly — entirely residential, no commercial districts, large minimum lot sizes, and an architectural review process that takes appearance seriously. Permitting here is more deliberate than in neighboring cities, by design.
Because Hillsborough parcels are large and heavily landscaped, site work — grading, drainage, tree protection, and access — is a bigger share of a project here than in a city with compact lots. It deserves its own line in the budget rather than being folded into general conditions.
Permit fees and review times change. Check current requirements on the Town of Hillsborough Building Department building permits page before planning around a date.
Hillsborough reviews exterior work on how it looks and how it sits on the property. That is the town's central planning concern, and it is why the place looks the way it does.
Practically, it means design comes first and takes longer. A project that would move quickly in a neighboring city will move deliberately here, and the drawings need to be more developed earlier. That is not an obstacle so much as a different rhythm, and it is worth setting expectations around at the start rather than mid-project.
A 1930s Hillsborough estate has the same century-old systems questions as any pre-war house, at a larger scale. Original wiring across a substantial floor plan, galvanized plumbing runs measured in hundreds of feet, heating systems designed for a different era, and foundations that predate seismic requirements.
The scale changes the arithmetic rather than the nature of the work. We survey systems thoroughly before pricing, because on a large older property the difference between an assumption and a survey can be very large indeed.
