Can I build on this land? The zoning and permit checks to run first

Buildability is not a property of the land. It is a decision the county has already made in writing, and you can read that decision before you spend anything. Here is the order we run it in.

1. Identify the zoning district and permitted uses

Find the parcel on the county or municipal zoning map, then find that district in the zoning ordinance. You are looking for whether a single-family dwelling — or whatever you intend — is permitted by right, permitted with a conditional use permit, or not permitted at all. Agricultural and forestry districts frequently allow a residence; some conservation and resource districts do not. Unzoned counties still exist, and there the building and health codes carry the weight instead.

2. Confirm it is a legal lot of record

This one surprises people. A parcel can have its own tax bill and still not be a legally recognized building lot, usually because it was split off years ago without going through subdivision approval. Ask the planning department directly whether the parcel is a legal lot of record eligible for a building permit. An illegally created parcel may require a subdivision or variance process before anything can be permitted.

3. Check minimum lot size, setbacks and frontage

• Minimum lot area and minimum lot width for the district.
• Front, side and rear setbacks, plus any stream, wetland or ridgeline buffer.
• Required road frontage, and whether a private easement satisfies it.
• Maximum height and lot coverage.
• Driveway and culvert permit standards, including sight distance at the road.

Draw the setbacks and buffers on the parcel map. On narrow or heavily constrained parcels this exercise alone sometimes leaves no buildable envelope at all.

4. Overlay the environmental constraints

FEMA flood zones and floodway, National Wetlands Inventory, steep-slope and erosion-control rules, and any state critical-area or coastal program. Floodway is the strictest: many jurisdictions will not permit a habitable structure inside it under any conditions. Wetlands typically require a delineation and possibly a federal permit before disturbance.

5. Confirm water, septic and power

No sewer means a septic system, which means soil that passes a perc test. No public water means a well, so check typical depth and yield for the area with the state well-log database. Then call the electric utility with the parcel number and ask for a distance-to-service estimate — running power a half mile is routinely a five-figure line item, and it is the one buyers most often forget to price.

6. Check the private layer too

Zoning is public. Deed restrictions, covenants and dormant property owners' associations are private, recorded, and enforceable independently of the county. A parcel zoned for a manufactured home may still be subject to a 1997 covenant prohibiting one. Both layers have to say yes.

Questions worth asking the county by phone

• Is this parcel a legal lot of record eligible for a building permit?
• What district is it in, and is a dwelling permitted by right?
• Are there prior permits, violations or open enforcement actions on this parcel?
• Is there a perc or soil evaluation on file for it?
• What is the full permit sequence and current timeline for a new dwelling here?

Write down the name of everyone you speak to and the date. Verbal answers from a planning counter are useful, but the ordinance and the recorded documents are what govern — and those are what belong in your file before you write an offer.
