What Survey Do I Need for a Building Permit?
Permit requirements vary by city/county, but many projects need a site plan showing setbacks and improvements.
What kind of survey is needed for a permit?
There is no single permit survey. The right scope depends on what the city, county, builder, engineer, or architect is asking you to prove. Some projects only need property-line verification for setbacks. Others need measured structures, topo data, drainage information, or a drawing that coordinates with design plans.
The safest way to avoid overbuying or underbuying scope is to get the requirement in writing before you ask for quotes. A one-line note from the permit office can save a full round of revisions.
Step 1: ask your permit office what they require
Before you hire anyone, ask the city/county exactly what they need for your permit application (and in what format). Requirements can range from a simple sketch to a stamped plan.
Common survey needs for permits
- Boundary survey / boundary verification to establish property lines for setback compliance.
- Topo survey when plans need elevations/contours (grading, drainage, engineering).
- As-built / improvement location to show where existing structures sit relative to lines.
If you’re not sure which category your project fits, use the Survey Types picker.
Common permit scenarios
- Additions, garages, ADUs, and sheds: boundary verification is often needed so setbacks can be shown accurately.
- Pools, retaining walls, and hardscape: property-line verification may be enough, or a fuller site drawing may be required.
- Drainage, grading, and engineered site work: topo data becomes more important because elevations drive the plan.
- Projects on raw land: address access, parcel details, and monument recovery early because the site may not be easy to locate.
What to send to a surveyor (to get a fast, accurate quote)
- Your address + parcel/lot info (if you have it).
- Project description (addition, ADU, pool, retaining wall, driveway, etc.).
- Any written permit requirements or checklist from the city/county.
- Timeline (rush vs flexible).
What changes permit survey cost and timing?
- Deliverables: field verification alone is different from a stamped drawing or topo package.
- Site complexity: sloped lots, heavy vegetation, missing corners, and active construction slow the job down.
- Coordination: when a builder, architect, engineer, or permit reviewer needs specific outputs, surveyors need those requirements up front.
- Rush deadlines: permit submittal dates can force premium scheduling, especially in busy markets.

FAQ
Do I need a survey for a building permit?
It depends on the project and your city/county. Many permits require a site plan showing setbacks and improvements. Start by asking the permit office what they need in writing.
What survey types are commonly used for permits?
Common permit needs include boundary verification (for setbacks), improvement location/as-built drawings, and topo surveys when elevations/contours are required for design or grading. If you’re unsure, use Survey Types.
Can a surveyor provide a site plan for my permit?
Often, yes — many surveyors can produce a drawing showing boundaries and measured improvements. Building design plans may still require an architect or engineer depending on your jurisdiction.
What should I send a surveyor to get an accurate quote?
Send the address (or parcel/lot), a brief project description, any written permit checklist/requirements, and your timeline. For exact pricing, request quotes.
