For serial builders & flippers
Cut weeks off pre-construction. Across every parcel.
Builders win or lose money before a shovel moves — in feasibility, code research, and permit strategy. faircompanies.build turns that work into a guided conversation, so a parcel you bought on Monday can be permit-ready by month-end.
Pre-construction in days
Drop in an APN or address. Get zoning, hazard, and permit-history in minutes — same data sources the pros pay for, surfaced as plain-English answers.
Cost-aware concepts
Iterate dwellings against your budget and your local labor market. Rough BOMs and value-engineering trade-offs are first-class outputs, not afterthoughts.
Portfolio that compounds
Every parcel you run through faircompanies.build sharpens the next one — your jurisdiction notes, your aesthetic preferences, your trade-off rules carry forward.
Where it fits
Concrete use cases
Underwriting a lot before close
Run feasibility, lot fit, and a 5-minute jurisdiction summary so you know setbacks, FAR, and likely permit timeline before you make an offer.
Picking between three properties
Spin up parallel concept iterations across each parcel and compare buildable square footage, ADU eligibility, and cost-to-build side by side.
Handing off to your GC
Generate a permit-set PDF, scope list, and BOM your contractor can actually price — not a vague Pinterest board.
Flipping with intent
Use the value-engineering stage to surface where to spend (and where not to) before drawings are even started.
How it works
