Summary
Upper Darby's home occupation ordinance flatly bars any outside sign advertising a home-based business. § 550-41B(4) says a non-impact home occupation, the only category of home business the Township allows, may show 'no outside appearance of a business use, including, but not limited to, parking, signs or lights,' making Upper Darby a strict no-signage jurisdiction for home businesses.
B. Non-impact home occupation standards. A non-impact home occupation is a business or commercial activity administered or conducted as an accessory use which is clearly secondary to the use as a residential dwelling and which involves no customer, client or patient traffic, whether vehicular or pedestrian, pickup, delivery or removal functions to or from the premises, in excess of those normally associated with residential use. ... (4) There shall be no outside appearance of a business use, including, but not limited to, parking, signs or lights.
Full Breakdown
§ 550-41 permits only 'non-impact' home occupations, defined as a business run as an accessory use clearly secondary to the residential use, with no customer, client or patient traffic and no pickup, delivery or removal activity beyond what a normal household generates. ' Other conditions in the same list reinforce the low-visibility model: the business can employ only family members residing in the dwelling (B(2)), cannot display or sell retail goods (B(3)), cannot occupy more than 25% of the habitable floor area (B(7)), and must meet the Township's commercial-motor-vehicle parking limits in § 550-33B(1) and (2).
Chapter 550 defines an 'ACCESSORY USE SIGN' in § 550-36 as 'any sign which identifies a home occupation,' but no district's permitted-sign table in § 550-37 actually authorizes one, so the definition exists without a matching allowance and the practical rule remains the § 550-41B(4) ban. Twelve use categories, including beauty shops, retail sales, and vehicle repair, are barred from qualifying as a home occupation at all under § 550-41C, regardless of signage.
Violations & Fines
A home occupation displaying a sign, exterior lighting, or any other outward business appearance loses its non-impact status and its underlying zoning approval. The Zoning Officer can revoke the use and occupancy permit under § 550-53, and the operator faces a civil judgment of up to $500 per day under § 550-53G, plus court costs and the Township's attorneys' fees, appealable to the Delaware County Court of Common Pleas.
