About this appAI proposal
Yardline helps homeowners plan a backyard office or shed. Enter your address, the size you want and how you will use the space. It drafts a layout and flags the setback, height, size and permit questions that may apply to your lot.
You refine the design by chatting: move the door, add a window, shrink the footprint. Each change is rechecked, and anything the tool cannot confirm is listed as an open question for your city office or HOA instead of being hidden.
It is for people who want to do the groundwork themselves before paying an architect or builder. Yardline is a planning aid, not a permit approval, and it shows where a licensed professional is still needed.

- Why this name
- A yardline is the edge of your lot, where setbacks and rules begin. The word is short, plain and easy to say.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Address-based rule check
Start from your address. Yardline lists the setback, height, size and permit rules it found for your lot and shows where each came from.

Open questions list
Anything not confirmed is flagged as a question for the city or HOA, so nothing is silently assumed.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Users share a read-only design link or permit packet with partners, builders, architects and HOA boards, who see the Yardline name on the plans.
- Do they become customers?
- Reviewers are often other homeowners or professionals, but most will only view once. Test whether builders and neighbours with their own yard projects start a free plan from the link.
- First customers
- Homeowners in one US metro with a clear shed or accessory structure rule set, planning a backyard office of under 200 square feet.
- Where to reach them
- Local homeowner forums: Answer backyard office and permit questions in city subreddits and neighbourhood groups, offering free rule checks.
- Hacker News and remote-work communities: Show the tool to the people who already discussed the problem and ask for test addresses.
- Local shed builders: Offer builders a way to send clients a pre-checked design link.
- First milestone
- Twenty free rule checks in one city, and five of those users paying for the permit packet.

RisksAI inference
- DataZoning and building code data differs by city and changes often. Coverage may start in only a few places, and stale rules could mislead users.
- RegulatoryUsers may treat the output as permit approval or professional advice. Clear disclaimers and a licensed-pro handoff are needed, and stamped plans may be required locally.
- AIThe chat may suggest edits that break a rule or state a rule wrongly. Every edit needs a deterministic recheck, and unknowns must be shown.
- CommercialThe evidence is one Hacker News post with 42 points and 24 comments. Demand and willingness to pay are untested.
- TechnicalReading parcel boundaries and placing a building on an irregular lot is harder than a plain rectangle.
