What can you build on this lot?

LotLens answers one question for a US parcel: what the zoning rules leave room to build. Enter an address and you get the parcel, its zoning district, the front / side / rear setbacks with the source of every number, the zoning envelope and the max building the coverage and height limits allow — as a site plan, a 3D massing model, the FEMA flood zone, neighborhood context and a written feasibility report you can download as a PDF.

We built it because the gap between “I’d like to add a garage, an ADU or a second story” and “I know what is actually allowed here” is filled with zoning codes, GIS portals and consultations most people never get to. LotLens gives you the first honest picture in minutes — including what it cannot know, so you can verify the right things with the city before you commit.

Coverage: the United States. The zoning rules are read from the jurisdiction’s own published code by an AI research agent, every number with its section and a quote that we check on the code page; Regrid’s published values are used where its zoning data carries them, and a number no source gives is a generic estimate, marked as one. Every report states which numbers come from where.

The company

LotLens is made by Lotlens LLC, an independent company registered in Texas: a studio of licensed architects, planners and researchers that builds small planning tools, each answering one question well. The Lot Report is the first. LotLens Model, a paper model kit of a US house measured from public lidar, and LotLens Massing, for building plots in Austria, Germany and Switzerland, are in early access beside it, and each follows the same idea: one address in, one clear answer out.

The people behind it come from architecture, urban research and software. They have spent years reading zoning codes for design work, and they know how much of that reading is mechanical: find the district, find the setbacks, draw what is left. A computer can do that part in seconds and show its work. The judgment that follows still belongs to you, your architect and your city.

LotLens is not a broker, a lender, a builder or a city agency. It earns money one way: people buy its reports and model kits. It sells no advertising and no leads, it does not sell personal data, and it never contacts property owners. Payments are handled by Paddle, the merchant of record, so LotLens never sees your card details.

How we work

Numbers are computed, not generated

Envelopes and footprints are computed from geometry and the rules. AI finds the street side, reads the city’s code (each number with its section and a quote we check on the page) and writes the narrative. It does not produce the computed numbers.

Every number names its source

Each rule is tagged: Regrid’s published value, the city’s code with a checked quote, an AI reading we could not confirm, or a generic estimate. An estimate looks like an estimate.

We say what we do not know

Deed restrictions, easements, trees and overlay rules are not modeled, and the report says so. When a data service does not answer, the report says “not determined” instead of guessing.

One price, no subscription

Finding your lot on the map is free. A report is a one-time purchase for one address, delivered online, as a PDF and by email. An account is optional and free.

How the rules are read, how a quote is checked on the code page, and how the reading is measured against districts read by hand: how the rules are read and checked.

Important Information

Informational only. LotLens reports are preliminary feasibility analyses for general informational purposes. They are not legal, financial, engineering, architectural, surveying, real estate, tax, or construction advice, and do not create a professional, fiduciary, agency, attorney–client, or broker–client relationship.

Not a substitute for licensed professionals. Before making any acquisition, design, financing, demolition, or construction decision, verify all relevant facts and consult licensed professionals in your jurisdiction — at minimum an architect, structural and civil engineer, land surveyor, real estate attorney, REALTOR® with MLS access, and your local planning and permitting authorities.

Data accuracy & currency. Reports aggregate information from third-party providers and public datasets. Sources update on varying schedules, can contain errors or omissions, and may not reflect the most current ordinance, regulatory, ownership, valuation, or environmental status. Setbacks, height limits, FAR and coverage limits are taken from third-party data and from the jurisdiction's published code as an AI lookup read it; a value shown with a checked quote was found in that text by LotLens, not confirmed by the jurisdiction. Every regulatory parameter shown, with the flood zone, opportunity-zone status and deed restrictions, may be incorrect, outdated or superseded and must be confirmed with the jurisdiction before reliance.

AI-generated content. The written analysis in every report is produced by an artificial-intelligence model from the computed data, and the site plan and 3D massing are generated from the parcel geometry and zoning rules. AI image models also draw the cover rendering, the sharpened aerial, the front elevation drawing and the neighborhood illustration: interpretations, not photographs, and not drawings to build from. AI text can contain factual errors or misinterpretations of source data. Drawings are illustrative only — they are not architectural drawings, surveys or construction documents.

Copyright and use of reports. Every report, with its text, figures and images, is © LotLens LLC. A purchased report is licensed to the purchaser for personal use in deciding about that property and may be shared for that purpose with the purchaser's own advisors, lender, architect or contractor. It may not be resold, republished, posted online, or used in a listing, an advertisement or other commercial material. The data behind it remains the property of its sources under their own terms.

Rules change locally. Land-use regulations are highly local and change frequently. Overlay districts, planned-unit developments, historic-preservation designations, environmental overlays, subdivision plats, private deed restrictions, HOA covenants, easements, and municipal moratoria may significantly restrict what may be built — and may not be captured in any report. In Houston and surrounding unincorporated Harris County jurisdictions there is no traditional municipal zoning; private deed restrictions and Chapter 42 subdivision standards are typically the binding control mechanism and must be independently researched.

Non-disclosure states. Texas and about a dozen other states do not disclose sale prices. There, actual sale prices are confidential and accessible only through the MLS via licensed real-estate professionals. Any sale-price, market-value, or comparable-sale figure shown in a LotLens report is an estimate derived from public sources and should not be relied upon as the actual transaction price.

No brokerage, no solicitation. LotLens is not a licensed real-estate broker or sales agent. Nothing in a report constitutes an offer to buy, sell, lease, finance, or solicit any property or financial product, nor an endorsement of any contractor, lender, architect, engineer, or other professional. Options a report plays through are analytical observations, not recommendations to build or to transact.

No warranty; limitation of liability. Reports are provided “as is” without warranty of any kind, express or implied. Liability is limited as set out in section 7 of the Terms: no indirect or consequential damages, and never more than the amount paid for the report concerned. A report is prepared for its purchaser; no one else may rely on it, and it is not a substitute for the advice of an attorney.

Assumption of risk. Any reliance on a report is at your sole risk. You are solely responsible for independently verifying any fact, figure, regulation, or conclusion before acting on it.
