Best for: A real estate or data person who enjoys turning municipal code into software rules
The ideaWhat this actually is
An automated report product that answers the first accessory-dwelling-unit question for any address: what the lot's zoning, setbacks, and coverage rules allow, roughly what it would cost to build, and what the permit path looks like. It is generated from parcel and municipal data in minutes for a flat fee, presented as a preliminary feasibility screen, not a survey or permit guarantee, with contractor, consultant, and lender referrals behind it.
The opportunityWhy this idea works
Homeowners curious about a backyard home hit a wall: zoning codes they cannot read, contractors who only answer after a sales visit, and consultants priced for people who already decided. The can-I-even-do-this question is answerable from parcel data and municipal rules, which means it can be a product instead of an appointment. Search demand is high, the report is cheap to generate once the rule engine exists, and the flat fee captures curiosity without a sales call while the real money layers behind it in referrals. Depth in a few ADU-friendly metros beats a shallow national promise.
The openingWhy this idea is overlooked
Turning municipal code into reliable software rules is tedious and locally specific, so most people assume it cannot be productized and default to consultations. The accuracy bar is high because a wrong answer is worse than no answer, which scares off casual builders. Someone who enjoys encoding zoning rules and knows when not to auto-answer can build an accuracy reputation that becomes the business.
The buildWhat you need to build this
| You need | Why it matters |
|---|---|
| Rule engines for a few ADU-friendly metros | Encoding each city's setbacks, lot coverage, height, parking, and owner-occupancy quirks, in metros where state law forces cities to allow ADUs, gives depth where demand is proven. Accuracy is the business. |
| A clear feasibility-screen disclaimer | Stating that the report is a preliminary screen from public data, not a survey, engineering opinion, or permit guarantee, and that unusual lots need professionals, protects you and positions the report honestly. |
| A parcel and zoning data pipeline | Parcel geometry, zoning layers, and assessor data feed the rule engine, with flags for slopes, easements, or overlays where automation is unreliable, routing those to manual review. |
| A decision-grade report | A buildable-envelope diagram, allowed size and height, a realistic local cost range, the permit sequence with timelines, and next steps let the homeowner decide whether to spend real money investigating. |
| A referral monetization layer | Vetted contractor referrals, a paid consultation tier, and lender partnerships for feasibility-to-financing are where the real revenue is, behind the flat report fee. |
| Professional distribution channels | Realtors marketing ADU-potential listings and renovation lenders wanting qualified leads distribute you via white-label or bulk pricing, turning one-off sales into a B2B channel. |

Questions
What people ask about this idea
Is the report a permit or a guarantee?
No. It is a preliminary feasibility screen from public data, not a survey, engineering opinion, or permit guarantee, and unusual lots need professionals. That disclaimer is stated plainly.
How can zoning become a product?
The can-I-even-do-this question is answerable from parcel geometry, zoning layers, and municipal rules encoded as a rule engine, which turns a consultation into a per-address report.
Why only a few cities?
Accuracy is the business, and each city's rules differ. Depth in a handful of ADU-friendly metros beats a shallow national promise that produces wrong answers.
Where does the real money come from?
Behind the flat report fee: vetted contractor referrals, a paid consultation tier, and lender partnerships for feasibility-to-financing.
How does it scale beyond one-off sales?
Through agents and lenders. Realtors marketing ADU-potential listings and renovation lenders wanting qualified leads distribute reports via white-label or bulk pricing.
