Measured drawings built on real Hillsborough conditions

Planning a project in Hillsborough? Precise as-built drawings are the foundation that keeps it on schedule and out of trouble at plan check. Hillsborough is a wooded enclave of grand estates and Mediterranean-style mansions on large hillside parcels above Burlingame.

Every downstream decision — structural, layout, budget — leans on the base drawings, so getting them field-verified up front pays for itself many times over. The Bay Area is defined by Victorian and Edwardian homes, Craftsman and Eichler neighborhoods, and modern tech-era infill. Aging structures and seismic considerations make reliable as-built plans indispensable for remodels, additions, and unit conversions.

FastAsBuilt combines on-site laser measurement with senior CAD drafting to document existing conditions across Hillsborough and the rest of San Mateo County. You get clean, dimensioned floor plans, elevations, and sections you can hand straight to your architect, designer, contractor, or the Town of Hillsborough Building Division.

Why Hillsborough owners order plans

Projects that start with accurate as-builts

Across Hillsborough, the most common reasons property owners come to us are simple: they need drawings that reflect what is really there.

Additions & remodels

Adding square footage or reworking a floor plan in Hillsborough starts with drawings that match the current building exactly.

Historic remodels

Hillsborough's older homes demand sensitive, accurate documentation before any renovation in a protected district.

Permit submittals

Additions, ADUs, and tenant improvements in Hillsborough all require accurate as-built drawings for the building department.

Buying & selling

Realtors and owners in Hillsborough use measured floor plans and verified square footage to market and close with confidence.

Insurance & records

Accurate documentation of your Hillsborough property protects you for insurance, appraisals, and future planning.

Permitting in Hillsborough

Drawings the Town of Hillsborough Building Division will accept

Bay Area jurisdictions combine some of the highest property values in the nation with strict, design-review-heavy permitting. Cities routinely require detailed as-built drawings for additions to older housing stock, and accurate documentation is critical where lots are small and every square foot is contested.

In Hillsborough, plans for additions, accessory dwelling units, and tenant improvements are submitted to the Town of Hillsborough Building Division. Reviewers compare your proposed work against documented existing conditions, so an accurate as-built set is what keeps a project from stalling in plan check.

Our Hillsborough drawings are prepared with California requirements in mind, including Title 24 energy documentation, current ADU regulations, and seismic considerations common to San Mateo County. That groundwork means fewer correction cycles and a faster path to approval.

Most Hillsborough building departments will not begin a meaningful review without existing-condition drawings, because they establish the baseline for setbacks, egress, occupancy, and how much of a structure is being altered. California ADU law has made garage and accessory-unit conversions especially popular, and each of those projects hinges on documenting exactly what is there before new work is proposed. Starting with a verified as-built set is the single most reliable way to avoid a stalled permit in Hillsborough.

Local architecture

The buildings we measure in Hillsborough

Hillsborough has a very different feel from denser Bay Area neighborhoods. Instead of tight lot lines and repeated tract plans, you see wooded grounds, long driveways, and large homes stepping across hillside parcels above Burlingame. In areas like Lower North, Country Club Manor, Tobin Clark, Carolands, and Black Mountain, the housing stock often leans Mediterranean and Spanish in character, with stucco walls, tile roofs, courtyards, arched openings, and wings added over time.

That architectural mix matters when you need existing-condition drawings. Homes of this scale often include offsets, split levels, terraces, irregular footprints, and changes made through earlier remodels that are not always reflected in older plans. FastAsBuilt documents these properties with on-site laser measurement, then our senior drafters turn the field data into permit-ready CAD files in PDF and DWG format. For Hillsborough houses, precise measurement helps capture the true relationship between interior spaces, exterior walls, grade transitions, and attached or semi-detached elements that can affect design and permitting.

Common projects

Why Hillsborough owners need as-built plans

Owners in Hillsborough usually come to us when a project starts with a complicated existing house rather than a blank slate. Common requests include hillside additions, historic remodels, and substantial home additions where the design team needs dependable base drawings before planning can move forward. On large estate properties, even a seemingly straightforward scope can involve multiple levels, older wings, and exterior features that need to be measured accurately.

FastAsBuilt is often brought in when you need to document:

  • an existing Spanish or Mediterranean residence before a major remodel
  • a sloped-site addition where floor levels and building footprint must be verified
  • an older home with incomplete or outdated drawings
  • a large house where designers need clean CAD backgrounds for coordination

Because Bay Area homes often carry age, complexity, and seismic considerations, verified as-built plans reduce guesswork early. Our 2D as-built plans start at $900, 3D as-built plans start at $1,500, and typical residential turnaround is 48 to 72 hours for local Bay Area projects.

Permitting

Working with the Town of Hillsborough Building Division

When you submit for work in Hillsborough, the Town of Hillsborough Building Division will expect clear, consistent documentation of existing conditions, especially for additions and remodels to large custom homes. In a town known for hillside sites and design-sensitive residential work, accurate base plans help your architect, engineer, and builder present a coordinated set instead of relying on partial legacy drawings.

That matters even more where older houses have been altered over time or where floor plates, setbacks, and grade relationships need to be understood from the start. FastAsBuilt provides field-measured as-built drawings using on-site laser measurement, followed by permit-ready CAD files prepared by senior drafters, so you can move into design and submittal with a verified record of what is actually there.

What Hillsborough area clients say

Real feedback from property owners and pros we've measured for across San Francisco Bay Area.

★★★★★
“We had no plans for our 1960s ranch house. FastAsBuilt measured it on a Tuesday and we had permit-ready PDFs and CAD by Friday. Our ADU project started on schedule because of it.”
Steven K.
San Jose, CA · ADU project
★★★★★
“Our Victorian had decades of quirky modifications. The field techs caught details other services missed, and the drawings reflected the house as it actually is.”
Grace F.
Oakland, CA · Victorian renovation
★★★★★
“SF plan check is unforgiving. These as-builts were dimensioned, layered, and formatted the way DBI expects, and our expediter had zero notes. That never happens.”
